...free world's camgaign to bolster democracy. Most have been detained for more than seven years in camps, many of them in Western Europe. There is a two-fold danger here: at best these people will have a political apathy toward democratic countries, and at worst they react with violent hostility toward the free world. In effect we are nurturing a modern type of savage deprived of the rights of existing laws...
Indo-China, said he, is the kind of thing that must not be handled by one nation trying to act alone. We must have a concert of opinion, he said, and a concert of readiness to react in whatever way is necessary. You had a row of dominoes set up, said Ike, and you knocked over the first one, and what would happen to the last one was the certainty that it would go over very quickly...
...early days of nuclear energy, only two main ingredients, U-235 and plutonium, were available to the bombmakers, and both behaved about the same. Now the situation is more complicated. Many light isotopes are suitable for fusion, and under the conditions in an exploding bomb, they may react with one another in many different ways. They also react with the products, e.g., neutrons, given off by the fission detonator, and with materials in the casing of the bomb. As the temperature changes, their behavior changes too. So a diagram describing the behavior of a fusion bomb can give only...
...main reaction is the combination of L16 with H², forming two atoms of helium (He4) and giving off a flood of energy. Since helium is the final product, the well-designed bomb should produce as much of it as possible, but side reactions are likely. Neutrons from the reacting plutonium are apt to hit lithium atoms, turning them into helium and tritium (H³). Tritium may hit deuterium, yielding helium and a free neutron. The bomb-com-pounders may include other ingredients (e.g., lithium seven and ordinary hydrogen), and these will react in characteristic ways...
...Bulletin of the Atomic Scientists, Professor (of physics) Victor F. Weisskopf, of the Massachusetts Institute of Technology, says: "Whereas there are now numerically fewer refusals of visas, there are considerably fewer applications, as many foreign scientists react against the needless indignities and delays accompanying them. Rather than become involved in long, drawn-out procedures . . . [they show] complete reluctance to visit the U.S. for meetings...
