• 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.”...

Les cartes topographiques ordinaires, comme celles qui sont produites par l'Institut géographique national (IGN), sont à l'échelle de 1/100 000, 1/50 000 et 1/25 000. Pourles cartes militaires, l'échelle peut aller jusqu'à 1/15 800. Depuis le début du siècle, un certain nombre de pays participent à l'élaboration d'une carte standard du monde àl'échelle de 1/1 00...

• Géographie LA CARTOGRAPHIE

  La cartographie Les projections Construire une représentation plane ou faire une projection de la surface terrestre est difficile car il est impossible de développer une sphère sur une surface plane, de fait toute projection implique des déformations. Selon l'usage d'une carte, qu'elle soit une carte de représentation et de conservation ou une carte des surfaces, le carto­ graphe choisit des projections différentes. Il y a des projections dites conformes...

• Map - Geography.

  Often only southeast slopes are hachured or shaded, giving somewhat the effect of a bird's-eye view of the area illuminated by light from the northwest. Shadings orcarefully drawn hachures, neither of which give elevations, are more easily interpreted than contour lines and are sometimes used in conjunction with them for greaterclarity. IV MAP PROJECTIONS For the representation of the entire surface of the earth without any kind of distortion, a map must have a spherical surface; a map of this...

  Si les points A, B, C, a, b, et c sont placés arbitrairement sur une section conique, par exemple sur un cercle, et que le point A est relié aux points b et c, le point B à c et a, et le point C à b et a, alors les points d’intersection des couples de droites ( aC) et (A c), ( aB) et (A b), ( bC) et (B c) sont alignés. De la même manière, un autre théorème de géométrie projective est décrit par la figure 2, sur laquelle on a tracé six tangentes quelconques d’un cercle. Les droites rel...

• Population.

  year AD 1, and it took more than 1,500 years to reach the 500 million mark. Growth was not steady but was marked by oscillations dictated by climate, food supply, disease, and war. Starting in the 17th century, great advances in scientific knowledge, agriculture, industry, medicine, and social organization made possible rapid acceleration inpopulation growth. Machines gradually replaced human and animal labor. People slowly acquired the knowledge and means to control disease. By 1900 the worldp...

• Leonardo da Vinci.

  Leonardo's stylistic innovations are even more apparent in The Last Supper, in which he represented a traditional theme in an entirely new way. Instead of showing the 12 apostles as individual figures, he grouped them in dynamic compositional units of three, framing the figure of Christ, who is isolated in the center of the picture.Seated before a pale distant landscape seen through a rectangular opening in the wall, Christ—who has just announced that one of those present will betrayhim—repres...

• Qing Dynasty - History.

  The Manchus also dealt with the problem of Russian expansion into northeastern Asia. In 1689 the Treaty of Nerchinsk was signed by an envoy from the Manchu courtand a Russian representing Peter the Great. The treaty, the first between China and a Western country, established territorial boundaries and defined rules ofcommerce for the two powers. Through the mid-18th century, the Manchus continued to consolidate their power. In 1720 the Qing ruler sent forces to fight the Mongols in Tibet and the...

• Panama Canal - Geography.

  The size of ships using the Panama Canal has steadily increased. About 27 percent of the vessels that use the canal are built to the maximum dimensions that can passthrough it (a category called “Panamax”). This has prompted further widening of Gaillard Cut, so that the larger Panamax vessels may transit safely. However, some ofthe world’s commercial and military ships are too large for the canal. Since the 1940s, new U.S. battleships and aircraft carriers have been built exceeding the canal’sdi...

  Astrolabe (Observatoire de Lyon) 4/26/2007 page 2/9 II - Description. La dimension de l'astrolabe est laissée au choix du constructeur. La précision est fonction de la grandeur des cercles gradués. Mais les contraintes des matériaux utilisés limitent souvent l'astrolabe à tenir sur une feuille A4. Pour s'affranchir des dimensions, nous supposerons que le rayon de l'équateur sur la sphère céleste est pris pour unité. Tout autre astrolabe sera une homothétie centrée sur le pôle, a...

  (17 ft) tall, was carved from a block of stone that another sculptor had left unfinished. Michelangelo drew on the classical tradition in depicting David as a nude,standing with his weight on one leg, the other leg at rest ( see contrapposto). This pose suggests impending movement, and the entire sculpture shows tense waiting, as David sizes up his enemy and considers his course of action. While David reveals Michelangelo's expert knowledge of anatomy (he had been dissecting corpses for about...

• theories of Common-sense reasoning

  formulas of some logical language, and that the reasoning tasks underlying this intelligence can then be accomplished by means of logical deduction. Both the idea of using logic as an underlying representation language for artificial intelligence and the emphasis on formalizing common-sense knowledge are present even in McCarthy's very early work (for example, McCarthy 1959 ), but the project receives its clearest articulation in a paper jointly authored by McCarthy and Patrick Hayes (1969 )...

  (in New York City). These congresses were attended by increasing numbers of representatives from the United States, Europe, Africa, and the Caribbean. Severalimportant factors affected the growing popularity of the congresses. First, many delegates were sponsored by international labor movements, which were growing insize and power in the 1920s. A second factor was the growth of the black nationalist movement of Marcus Garvey. The Garvey movement was important in the UnitedStates as a popular ex...

Two of the semicircularcanals are in a vertical position and are used to detect vertical movement, such as jumping or falling. The third canal is horizontal and detects horizontal movement,such as turning or spinning. The action of the canals depends on the inertia of the fluid inside. When the motion of the body changes, the fluid lags behind, causing...

• Archaeology.

  Prehistoric archaeology is practiced by archaeologists known as prehistorians and deals with ancient cultures that did not have writing of any kind. Prehistory, a term coined by 19th-century French scholars, covers past human life from its origins up to the advent of written records. History—that is, the human past documented insome form of writing—began 5000 years ago in parts of southwestern Asia and as recently as the late 19th century AD in central Africa and parts of the Americas.

  Question 2 (géographie). Représentation globale de la Terre échelles et projections cartographiques 1. Il semble que, de tous temps, les hommes ont essayé de représenter l'espace sur lequel ils vivaient. C'est en Grèce qu'on peut définir le berceau de la cartographie. L'oekoumène (voir« 280 questions d'histoire et de géographie», p. 29, Ed. Tempes, 2006) semblait alors centré autour de la Méditerranée. Mais, ces premiers cartographes se sont rapidement heurtés à un problème majeur : il est impos...

• Flood Control.

  When scientific research into the causes of floods showed that the construction of levees was insufficient as a method of control, the first steps were made to provide forreforestation and soil conservation. The Clarke-McNary Act of 1924, the Mississippi Flood Control Act of 1928, and the McSweeney-McNary Act of 1928 were all directedtoward that end. In 1935 the Soil Conservation Service was established by the Congress of the United States under an act declaring a policy of permanent provision f...

• North Dakota - geography.

  Bismarck, the growing season averages 134 days, as the average date of the last killing frost is May 11 and that of the first killing frost is September 22. The length ofthe growing season drops to about 110 days in the northerly reaches of the state. The long periods of summer sunshine at this latitude, providing as much as 16 hoursof daylight in summer, help crops to mature quickly, thus compensating somewhat for the relatively short growing season. Temperatures in the north are, on the averag...
