Zaisser removed from the People's Police a hard core of former Nazi officers, carefully screened P.W.s and recruited youths. Then he set them up in Bereitschaften under direct control of the Russians. The ready squads, of 250 men each, are armed with rifles, submachine guns, machine guns and light artillery. In equipment they have a better start than did the bootleg German army of the '20s, which was also founded on a cadre of the best officer material...
...theory of the earth's birth and development. According to Urey, the earth and the moon were formed at the same time out of the primeval dust cloud around the sun. First materials to "precipitate" from the cloud were light stony silicates, which formed the cores of the earth and moon. But the earth's core was bigger than the moon's, and it attracted much more of the heavy iron which precipitated later from the dust cloud. For this reason, says Urey, the moon is lighter, volume for volume, than the earth...
Divided Land. But while life was evolving, the earth was heating up because of the radioactivity of its stony ingredients. The stony core got hotter and so did the stone-iron mixture. Eventually the outer mixture got soft enough for the iron to trickle down toward the center. Its "fall" of several thousand miles made the earth's middle layers even hotter...
Then, says Urey, the light stone core began to float up through the iron like a tennis ball through molasses. As it approached the surface, land appeared for the first time; the oceans were crowded to one side, as on the third day of biblical creation.* For a while the earth had only a single continent (Pangea), but the continuing rise of the core material and its spreading out near the surface broke Pangea into chunks and carried them apart. His theory, says Urey, accounts for the remarkable fact, first pointed out by Alfred Wegener in his theory of continental...
