• électronique de spin.

  La structure décrite ci-dessus est une « vanne de spin » ; elle peut être utilisée comme un détecteur de champ magnétique. Il suffit d’utiliser deux couches magnétiques présentant des comportements différents. La première, appelée « couche dure », est insensible à un champ magnétique externe ; au contraire, la seconde, dite « couche douche », voit son aimantation tourner en fonction de l’intensité du champ magnétique extérieur. Ainsi, en fonction de son orientation, un champ magnétique externe v...

• From Bulfinch's Mythology: Bacchus (Dionysus) - anthology.

  me their fishing rods and nets and their fisherman's trade. This I followed for some time, till growing weary of remaining in one place, I learned the pilot's art and howto guide my course by the stars. It happened as I was sailing for Delos we touched at the island of Dia and went ashore. Next morning I sent the men for fresh water,and myself mounted the hill to observe the wind; when my men returned bringing with them a prize, as they thought, a boy of delicate appearance, whom they hadfound a...

• Discrimination.

  Throughout United States history many other groups have suffered racial or religious discrimination. Since Europeans first came to America, Native Americans havebeen forcibly deprived of their lands and denied civil rights. Congress enacted the Indian Civil Rights Act in 1968, and the federal courts have entertained a number ofsuits designed to restore to Native American tribes ancestral lands and hunting and fishing rights. Many religious groups, including Roman Catholics, Jews, and others,have...

• Electron I INTRODUCTION Models of the Atom Once scientists discovered the electron, they set out to explain how electrons behave in atoms.

  Electron Density and Orbital ShapesAtomic orbitals are mathematical descriptions of where the electrons in an atom (or molecule) are most likely to be found.These descriptions are obtained by solving an equation known as the Schrödinger equation, which expresses ourknowledge of the atomic world. As the angular momentum and energy of an electron increases, it tends to reside indifferently shaped orbitals. The orbitals corresponding to the three lowest energy states are s, p, and d, respectively....

During months ofprotests, Albany’s police chief jailed hundreds of demonstrators without visible police violence. Eventually the protesters’ energy, and the money to bail out protesters,ran out. The strategy did work, however, in Birmingham, Alabama, when SCLC joined a local protest during the spring of 1963. The protest was led by SCLC member FredShut...

• Protestantism.

  F England The Anglican Church became the established church in England when Henry VIII assumed (1534) the ecclesiastical authority over the English church that had previouslybeen exercised by the pope. Henry’s motive was to annul his marriage to Catherine of Aragón rather than to reform church doctrine, and he imposed severe lawsupholding the major tenets of medieval Catholicism. Under King Edward VI and Queen Elizabeth, however, the Anglican Church developed a distinctly Protestant creedthat w...

• Democratic Party.

  At the beginning of the 20th century the Democrats’ minority position among voters remained central to their existence. The Progressive split in Republican rankshelped elect Woodrow Wilson twice, but the entry of the United States into World War I ended that. The war, popular at first, backfired against the Wilsonadministration when large numbers of German Americans and Irish Americans protested with their votes against U.S. involvement on England’s side. The result wasanother Republican landsli...

• Glacier.

  covered. In spring the snow cover begins to melt in the lower reaches, exposing the ice surface. As temperatures increase, the melting moves up the glacier. Thesnowline is the highest position the melting reaches during the year. Firn is old granular snow. The firn limit may not exactly coincide with the annual snowline since insome years rapid melting leaves behind firn patches below the snowline. Some glaciers exhibit features called ice streams and icefalls. Ice streams are valley glaciers th...

  and troops to Europe from the United States and other overseas sources. In 1914 Britain implemented a sea blockade of Germany to prevent the delivery of importssuch as food and war materials. The same year, Germany began using submarines to disrupt Allied seaborne traffic and prevent supplies from reaching Britain. In 1915Germany instituted a submarine blockade around Britain. From February 1915 to September 1915 and again in 1917, Germany used unrestricted submarine warfare,sinking ships withou...

• Maya Civilization.

  destruction was directed mostly at temples in the ceremonial precincts; it had little or no impact on the economy or population of a city as a whole. Some city-states didoccasionally conquer others, but this was not a common occurrence until very late in the Classic period when lowland civilization had begun to disintegrate. Until thattime, the most common pattern of Maya warfare seems to have consisted of raids employing rapid attacks and retreats by relatively small numbers of warriors, most o...

• 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...

• Bear - biology.

  programs sponsored by zoos or other breeding centers have attempted to breed giant pandas in captivity, although most of these programs have proved unsuccessful.Among the difficulties faced by captive breeders has been the problem of encouraging a female giant panda to mate with a selected male during the two to three daysof the year when she is most fertile, a period known as estrus. B Spectacled Bear Creamy-white rings surrounding the eyes give the spectacled bear its name. Its shaggy coat of...

• Track and Field.

  VI RUNNING EVENTS Running events are competitions that test athletes’ quickness, speed, and endurance. Athletes win running races by completing the distance or course in the leastamount of time. A Sprints The shortest running events, called sprints or dashes, are the premier events at a track-and-field meet. The outdoor sprints consist of the 100-meter, 200-meter, and400-meter events. Sprints contested at indoor meets include the 50-meter, 60-meter, 200-meter, and 400-meter events. Past champ...

These practices were promoted by the policy of mercantilism that many European colonial powers adopted. Those who advocated mercantilism believed that exports toforeign countries were preferable both to trade within a country and to imports because exports brought more money into the country. They also believed that thewealth of a nation depended primarily on the possession...

  as Marxists. They believed that the working class—with its struggles to organize trade unions and to bring about political reforms of benefit to the majority ofpeople—would become the primary force for revolutionary change. The Russian Marxists formed the Russian Social Democratic Labor Party (RSDLP) in 1898. By 1903,however, the RSDLP had split into two factions. The faction called the Bolsheviks (from the Russian word for “majority”), led by Vladimir Ilich Lenin, favored a more centralized a...

• Manhattan Project - U.

  other possible uses of nuclear energy, such as using uranium to operate large power plants or, perhaps, as power sources for ships or submarines. Then Nazi Germanyinvaded Poland on September 1, 1939, and Europe plunged into war. The scientists realized that any plans to build large-scale nuclear power plants would have to waituntil the war was over. Two weeks after the invasion of Poland, Hitler made a radio speech in which he threatened Britain with “a weapon against which there is no defense.”...

• Hungary - country.

  Northern Hungary lacks sufficient water, especially between July and October, when precipitation levels are typically low. Canals irrigate the Great Hungarian Plain,which is subject to drought. Because of the country’s mainly flat terrain, only limited water resources can be harnessed for hydroelectric power. F Environmental Issues Rapid industrialization in Hungary following World War II contributed significantly to a number of major environmental problems, including air, water, and soil pollu...
