Back in the 19305 when the nuclear era began, the building blocks of matter seemed simple enough. There were neutrons and protons nestled in the nucleus of the atom, electrons spinning around it, and photons to carry electromagnetic radiation. That seemed to be it. Then, after the big bomb-building breakthrough and the construction of billion-electron volt accelerators, scientists discovered a chaotic array of new particles. Some were so short-lived that their age was measured in less than a billionth of a second, their very existence inferred from the erratic tracks they left in bubble and cloud chambers...
...deal with the theme of atomic war. But unlike Fail-safe, in which a mere two cities are destroyed, Triumph obliterates two continents. The Russians--those traditional villains--start a war, their cunning leaders having first stashed away several thousand people in bombproof shelters. These people will provide a nucleus for Soviet world domination once the bothersome populations of both the U.S. and U.S.S.R. have been eliminated...
...shrugged off the letter's strong rejection of totalitarianism, and concentrated on its espousal of those causes-such as the liberation of the working classes and anti-colonialism-that Communists like to talk about. The Vatican radio hastily said that the Communists were missing the point: the "central nucleus" of the encyclical was "the dignity of the human being, his rights, his duties...
Relativistic Limit. A galactic explosion starts, say Hoyle and Fowler, when a large mass of gas accumulates in the center of a galaxy's nucleus. The gas behaves like a very large star, equal in mass to 100 million suns. For a while it burns hydrogen and changes it to helium just as normal stars do, and the temperature in its center rises to 70 million degrees. Then the star burns its helium, forming heavier elements. Its central temperature rises to 500 million degrees, while its powerful gravitation causes it to shrink toward its superheated middle. In spite...
