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.”...

1824. Jackson had won a plurality of the popular and electoral votes. But because he lacked a majority of the electoral votes, the House of Representatives had todecide the election among the three candidates with the highest number of electoral votes.

L'oeuvre de Dos passos
tivent par un procédé évident de montage cinématographique la vision personnelle de l'auteur. Ce procès d'une Cité destructrice broyant l'individu sous ses gratte-ciel et ses tonnes d'acier est aussi l'expression d'une fascination, d'une excitation lyrique et épique sans précédent. Roman expérimental, Manhattan Transfer l'est d'un bout à l'autre. Et c'est aussi l'évocation, pour donner l'alarme, de la plus terrible des « failure-stories...

At the party convention Mulroney was one of the candidates who ran against Clark. This time Mulroney did not have to contend with a rival candidate from Québec. Healso had the support of the remnants of the Diefenbaker faction—who disliked Clark even more than they disliked Mulroney. Mulroney was also endorsed by asubstantial group of members of Parliament; this endorsement helped allay concerns about whether he could provide effective leadership in Parliament.

fréquence et l'enregistrement numérique ont accru les exigences d'un public épris de qualité sonore autant que de musique, et de plus en plus éclectique. En même temps, l'internationalisation du système américain des « charts » et « hit-parades » (aujourd'hui normalisé en France par le « Top 50 ») a exacerbé la concurrence entre les éditeurs. À la fin des années soixante-dix, l'édition phonographique a connu une grave récession, puis une reprise spectaculaire a suivi la commercialisation du disq...

Igneous Rock.
As a magma cools, the first crystals to form will be of minerals that become solid at relatively high temperatures (usually olivine and a type of feldspar known asanorthite). The composition of these early-formed mineral crystals will be different from the initial composition of the magma. Consequently, as these growing crystalstake certain elements out of the magma in certain proportions, the composition of the remaining liquid changes. This process is known as magmatic differentiation.Sometime...

before eruption. Very violent explosive eruptions are called Plinian eruptions, after Roman naturalist Pliny the Elder. These eruptions can last for several hours to daysand eject a large amount of pyroclastic material. Some volcanoes can produce much more energetic eruptions that eject materials farther from the vents because oftheir andesitic and dacitic composition. Andesitic and dacitic lava is generally thicker than basaltic lava. Stiff lava generally produces more-explosive eruptions. B No...
