• Church (building) I INTRODUCTION Church (building), a building designed for worship for groups of Christians.

  nearby was a basilica; the two are now combined in one building, known as the Church of the Holy Sepulchre. The original Saint Peter's Basilica in Rome, replaced bythe present church during the Renaissance, was a huge processional basilica with projecting wings—transepts—forming a Latin cross in plan. The domed, centralizedform persisted in the Byzantine and Slavic East, where medieval churches, small in scale, often took the form of five domes arranged on a Greek cross plan. IV MEDIEVAL EUROPE...

• Dog Family - biology.

  muzzles, long and bushy tails, and large ears. Many foxes hunt by stalking prey and then leaping on it with a distinctive, stiff-legged pounce. Once thought to besolitary animals, foxes are now known to live in groups of up to six individuals. The remaining canids are each highly distinctive. Raccoon dogs and bush dogs are the least doglike canids in appearance. Raccoon dogs, found in eastern Asia, havestubby legs, a stout body, short ears, shaggy fur, and a black face mask that resembles a racc...

• Surrealism I INTRODUCTION Surrealism, artistic and literary movement that explored and celebrated the realm of dreams and the unconscious mind through the creation of visual art, poetry, and motion pictures.

  Hieronymus Bosch’s The Garden of Earthly Delights (about 1505-1510).© 2008 Salvador Dali, Gala-Salvador Dali Foundation / Artists Rights Society (ARS), New York./Bridgeman Art Library, London/New York Dreams, according to Freud, were the royal road to studying the unconscious, because it is in dreams that our unconscious, primal desires manifest themselves. Theincongruities in dreams, Freud believed, result from a struggle for dominance of ego and id. In attempting to access the real workings of...

• Folktales I INTRODUCTION "Little Red Riding Hood" The popular children's story "Little Red Riding

  seemed important to them. Thus, the Grimms postulated a common Indo-European origin for folktales, and the German philologist Theodor Benfey as well as theScottish writer William Clouston believed that stories diffused by way of travelers migrating east and west from India. Such theories, however, have proven incompleteand inadequate. Nevertheless, the research of these and other scholars greatly stimulated interest in folklore and folktales. The German scholar Max Muller held thatmyths originat...

• Illustration I INTRODUCTION Illustration, pictorial material appearing with a text and amplifying or enhancing it.

  Hypnerotomachia PoliphiliThe Hypnerotomachia Poliphili (The Strife of Love in a Dream), a work attributed to Dominican monk Francesco deColonna, was first published in Venice, Italy, in 1499 by Aldus Manutius. Its text and its beautiful woodcut illustrationsinfluenced Renaissance art and architecture. This illustration shows the book’s protagonist, Poliphilus, asleep under a tree.The Pierpont Morgan Library/Art Resource, NY The first illustrated book with a text printed from movable type was pro...

• Hardware (computer).

  Magnetic tape drives use magnetic tape similar to the tape used in VCR cassettes. Tape drives have a very slow read/write time, but have a very high capacity; in fact,their capacity is second only to hard disk drives. Tape drives are mainly used to back up data. Compact disc drives store information on pits burned into the surface of a disc of reflective material ( see CD-ROM). CD-ROMs can store up to 737 megabytes (MB) of data. A Compact Disc-Recordable (CD-R) or Compact Disc-ReWritable (CD-RW)...

• Dance I INTRODUCTION Dance Archive Films/BBC Worldwide Americas, Inc.

  features in its dance styles. The ordinary potential of the body can be expanded in dance, usually through long periods of specialized training. In ballet, for example, the dancer exercises to rotate,or turn out, the legs at the hips, making it possible to lift the leg high in an arabesque. In India, some dancers learn to choreograph their eyeballs and eyebrows.Costuming can extend the body's capabilities. Toe or pointe shoes, stilts, and flying harnesses are a few of the artificial aids employe...

• Blood.

  substances. For example, a person who is blood type A positive will not make antibodies against the A or Rh markers, but will make antibodies against the B marker,which is not on that person’s own red blood cells. If blood containing the B marker (from types B positive, B negative, AB positive, or AB negative) is transfused into thisperson, then the transfused red blood cells will be rapidly destroyed by the patient’s anti-B antibodies. In this case, the transfusion will do the patient no good a...

• Antelope - biology.

  antelopes still display complex patterns of behavior, although much of it is instinctive rather than learned. In open habitats, antelopes run a high risk of predation (being preyed upon). To survive they use several kinds of defensive strategy, including living in herds. Herd living ensures that many pairs of eyes and ears are on the alert for danger. Herd living also gives individuals a better chance of avoiding attack, because predators canchoose from many potential targets. When danger thre...

• American Music I INTRODUCTION American Music, the folk, popular, and classical music of the United States--created by American-born or American-trained composers, or originating in American culture, or written primarily for American audiences.

  The country's first permanent orchestra was the New York Philharmonic Society, founded in 1842. Among the first symphonic and operatic composers the mostprominent was William Henry Fry, who composed the first opera by an American ( Leonora, 1845). Fry is best remembered, however, for four symphonies written in the 1850s and 1860s. George F. Bristow wrote the first opera on an American theme; his Rip Van Winkle was performed in New York City in 1855. Town bands, a popular form of community mu...

• Rain Forest.

  dropped into the heart of the forest by helicopters. Suspended from the crane’s long, movable arm is a large gondola that functions as a mobile treetop laboratory.Moving from tree to tree, forest researchers collect specimens, conduct experiments, and observe life in the canopy frontier. The highest stratum of the rain forest is made up of the emergent trees, those individuals that stick up above the forest canopy. Emergents, which do not form acontinuous layer, are usually the giants of the for...

• Technology.

  loose soil in this region, known as the Fertile Crescent, was easily scratched for planting, and an abundance of trees was available for firewood. By 5000 BC, farming communities were established in areas known today as Syria, Turkey, Lebanon, Israel, Jordan, Greece, and the islands of Crete and Cyprus. Agricultural societies in these places constructed stone buildings, used the sickle to harvest grain, developed a primitive plowstick, and advanced their skills inmetalworking. Trade in flint al...

  history of architecture. See Basilica; Church; Early Christian Art and Architecture;Prayer. C Christian Life The instruction and exhortation of Christian preaching and teaching concern all the themes of doctrine and morals: the love of God and the love of neighbor, the twochief commandments in the ethical message of Jesus (see Matthew 22: 34-40). Application of these commandments to the concrete situations of human life, bothpersonal and social, does not produce a uniformity of moral or polit...

• Uzbekistan - country.

  E Environmental Issues The evaporation of the Aral Sea is one of the worst ecological disasters in the world. The Aral has shrunk so much that it now holds only about one-fifth the volume ofwater it held in 1960. The shrinkage is due to irrigation withdrawals from the Amu Darya and Syr Darya, a practice that began on a massive scale in the early 1960s aspart of the Soviet Union’s ill-conceived drive to increase cotton yields in Central Asia. Growing cotton in the naturally arid and saline soil...

• Encyclopedia of Philosophy: A posteriori ?

  do not appeal to considerations about irrevisability. Some versions appeal, instead, to considerations about thedependence of relevant evidence on sensory experience. 3 Foundationalism about empirical warrant The leading alternative to coherentism is foundationalism about empirical justification: empirical justification has atwo-tier structure in that some instances of such justification are non-inferential, or foundational, and all otherinstances of such justification are inferential,...

• Art, abstract

  without any optical interference, the figures have become enigmatic new realities inhabiting an equally unnaturalspace. This contrasts with the effect in Analytic Cubism of normal objects seen through a radically fractured lens.Another of the many currents of schematic abstraction is generally known as lyrical or expressionist and isrepresented by various works of Kandinsky, Franz Marc, Paul Klee and others. Objects and space are dematerializedby blurred and calligraphically naive transf...

• Legislative Branch.

  popularly elected parliament, composed of one or two chambers. The majority party, or a coalition of parties, agree to form a government, known as the government of the day . Executive power is exercised by a cabinet headed by a chief minister—usually called prime minister, premier, or chancellor—who is typically drawn from the membership of the legislature. Such systems are found throughout western Europe and in countries such as India that were once part of the British Empire. In systems base...

• Macroeconomics.

  IV INFLATION For several decades after World War II (1939-1945) the main inflation theories were demand-pull and cost-push. The cost-push theory basically emphasized the role ofexcessive increases in wages relative to productivity increases as a cause of inflation, whereas the demand-pull theory tended to attribute inflation more to excessdemand in the goods market caused by expansion of the money supply. A central concept in inflationary theory since the mid-1950s has been the Phillips curve...

• THE CONTRACT (droit anglais)

  REQUIREMENT FOR TERMS OF A CONTRACT Although contracts can be interpreted as almost any monetary exchange for goods or services, the terms of an agreement are often required so that compensation can be obtained if one party fails in its responsibilities. Without such specifications, it becomes almost impossible to seek reparations; for example, "we agree to sell/purchase a car for a fair price" is too vague for any decision to be reached at a later date. That being said, many contracts of a ve...

• Federalism.

  the Commerce Clause during the New Deal in the 1930s. The New Deal, which President Franklin Roosevelt created to confront the country’s economic depression,included laws affecting nearly every home and workplace. The Supreme Court upheld most of Roosevelt’s New Deal initiatives, including laws setting minimum standardsfor pay and working conditions, protecting labor unions, and regulating farm production. After World War II (1939-1945), national authority under the Commerce Clausecontinued to g...

• Dark Matter - astronomy.

  observed, and the measured frequency of such events has placed limits on how much dark matter can take the form of MACHOs. From the observations that have beenmade by astronomers, it is now known that MACHOs cannot be the dominant constituent of dark matter. There are simply not enough such gravitational lenses. Physicists suspect that a more exotic form of cold dark matter must exist. This form is not baryonic. Like neutrinos, this form barely interacts with ordinary matter, butis some type of...

• Development (biology) - biology.

  Understanding the molecular machinery within cells gives biologists a direct basis for understanding growth, because growth is the synthesis of new protoplasm, andbiologists know the basic mechanism of this synthesis. One key gap, however, exists in this knowledge. Biologists want to know not only how substances aresynthesized but also how growth is controlled so that the proportions of an animal or plant remain consistent from generation to generation. The direction and amountof growth, which a...

• Pollination - biology.

  rapidly as in cross-pollination, because one plant with a beneficial gene can transmit it only to its own offspring and not to other plants. Self-pollination evolved laterthan cross-pollination, and may have developed as a survival mechanism in harsh environments where pollinators were scarce. IV POLLEN TRANSFER Unlike animals, plants are literally rooted to the spot, and so cannot move to combine sex cells from different plants; for this reason, species have evolved effectivestrategies for ac...

• Child Abuse.

  C Social Isolation and Low Community Involvement Parents and caretakers who abuse children tend to be socially isolated. Few violent parents belong to any community organizations, and most have little contact withfriends or relatives. This lack of social involvement deprives abusive parents of support systems that would help them deal better with social or family stress. Moreover,the lack of community contacts makes these parents less likely to change their behavior to conform with community va...

• Endangered Species - biology.

  Red List database assesses the status of, and threats to, animal species worldwide. To add to this and other biodiversity databases, nongovernmental organizationssuch as Conservation International and World Wildlife Fund conduct periodic rapid assessments (focused, intensive evaluations) of biodiversity in varioushotspots— regions like Madagascar that are both rich in endemic species and environmentally threatened. This information is used in the administration of international agreements such...

• Classification - biology.

  species based on the fewest number of shared changes that have occurred from generation to generation. IV HISTORY OF CLASSIFICATION SYSTEMS Classification is one of the oldest sciences, but despite its age it is still a vigorous field full of new discoveries and methods. Much like other fields of science, greatthinkers have shaped the course of classification. One of the earliest classification schemes was established by Greek philosopher Aristotle, who lived in the 300s BC. Aristotle believe...

• Trigonometry I INTRODUCTION Trigonometry, branch of mathematics that deals with the relationships between the sides and angles of triangles and with the properties and applications of the trigonometric functions of angles.

  If point P, in the definition of the general trigonometric function, is on the y-axis, x is 0; therefore, because division by zero is inadmissible in mathematics, the tangent and secant of such angles as 90°, 270°, and -270° do not exist. If P is on the x-axis, y is 0; in this case, the cotangent and cosecant of such angles as 0°, 180°, and - 180° do not exist. All angles have sines and cosines, because r is never equal to 0. Since r is greater than or equal to x or y, the values of si...

• Computer Memory.

  been created, information can be retrieved but not changed. Newer technologies allow ROMs to be semi-permanent—that is, the information can be changed, but ittakes several seconds to make the change. For example, a FLASH memory acts like a ROM because values remain stored in memory, but the values can be changed. C External Memory External memory can generally be classified as either magnetic or optical, or a combination called magneto-optical. A magnetic storage device, such as a computer'shar...

• Latin American Music I INTRODUCTION Tito Puente Playing the Drums Since the 1950s American drummer Tito Puente has popularized Latin American music, especially the mambo, in the United States.

  Panpipe Music of BoliviaWell before the Spanish conquest, native peoples such as the Quechua and Aymara living in the Andes Mountains inBolivia, Peru, and Ecuador, developed a rich musical tradition. Panpipes (set of tuned pipes), made of ceramic, sugarcane,or bone were paired with shell trumpets, cane flutes, and drums, which accompanied dancers during religious and secularceremonies. Large ensembles of 4 to 20 panpipe players are still the norm, and Spanish influences have since beenintegrated...

• Millennium.

  Postmillennialism, also referred to as progressive millennialism, interprets the Bible less literally than premillennialism does. Postmillennialists regard the millennium as a1,000-year reign of Christian ideals that will end with the return of Christ. In this view, the millennium will not start suddenly through an apocalypse, but graduallythrough the efforts of human beings. Postmillennialists believe that through social reform and by upholding Christian ideals, the kingdom of God will be built...

• Air Pollution.

  Several pollutants attack the ozone layer. Chief among them is the class of chemicals known as chlorofluorocarbons (CFCs), formerly used as refrigerants (notably in airconditioners), as agents in several manufacturing processes, and as propellants in spray cans. CFC molecules are virtually indestructible until they reach thestratosphere. Here, intense ultraviolet radiation breaks the CFC molecules apart, releasing the chlorine atoms they contain. These chlorine atoms begin reacting withozone, br...

• Primate - biology.

  The primate order includes a handful of species that live entirely on meat (carnivores) and also a few that are strict vegetarians (herbivores), but it is composed chieflyof animals that have varied diets (omnivores). The carnivorous primates are the four species of tarsiers, which live in Southeast Asia. Using their long back legs, thesepocket-sized nocturnal hunters leap on their prey, pinning it down with their hands and then killing it with their needle-sharp teeth. Tarsiers primarily eat in...

• Toys. I INTRODUCTION Toys, objects that serve as playthings for children. Although the

  clay. These readily available elements were also used to make more elaborate toys as human society advanced. Archaeologists have found primitive, handmade toys such as wooden or cloth dolls, clay marbles, and terracotta figures that date back thousands of years. In ancientEgypt, Greece, and Rome, people placed dolls or clay figures in the graves or tombs of children for them to play with in the afterlife. The yo-yo may seem like a 20th-century fad, but it actually dates back at least 2,500 years...

• Great Depression in the United States - U.

  prices would continue to rise and they could soon sell their stocks at a profit. The widespread belief that anyone could get rich led many less affluent Americans into the market as well. Investors bought millions of shares of stock “on margin,” arisky practice similar to buying products on credit. They paid only a small part of the price and borrowed the rest, gambling that they could sell the stock at a highenough price to repay the loan and make a profit. For a time this was true: In 1928 the...

• Blacks in Latin America.

  Throughout Latin America and the Caribbean the slave population declined at the astonishing rate of 2 to 4 percent a year; thus, by the time slavery was abolished, theoverall slave population in many places was far less than the total number of slaves imported. The British colony of Jamaica, for example, imported more than 600,000slaves during the 18th century; yet, in 1838, the slave population numbered little more than 300,000. The French colony of Saint-Domingue (present-day Haiti)imported mo...

• Pottery I INTRODUCTION Pottery, clay that is chemically altered and permanently hardened by firing in a kiln.

  basket, or a clay or plaster form. Liquid clay can be poured into plaster molds. A pot can be coil built: Clay is rolled between the palms of the hands and extended intolong coils, a coil is formed into a ring, and the pot is built up by superimposing rings. Also, a ball of clay can be pinched into the desired shape. The most sophisticatedpottery-making technique is wheel throwing. The potter's wheel, invented in the 4th millennium BC, is a flat disk that revolves horizontally on a pivot. Both...

• Light - astronomy.

  Each different frequency or wavelength of visible light causes our eye to see a slightly different color. The longest wavelength we can see is deep red at about 700 nm.The shortest wavelength humans can detect is deep blue or violet at about 400 nm. Most light sources do not radiate monochromatic light. What we call white light,such as light from the Sun, is a mixture of all the colors in the visible spectrum, with some represented more strongly than others. Human eyes respond best to greenlight...

• Native American Architecture.

  B Relationship to the Universe and Nature A more profound difference between European American and Native American perceptions lay in how human beings saw themselves in relationship to the universe andin what they believed their responsibilities were to the natural world and to each other. Most European Americans saw themselves as separate from creation andadversaries of nature, ever struggling to conquer and subdue nature and force it to yield to their will. Native Americans saw themselves as...
