...curve of decay, plotted on a chart, normally consists of portions of two straight lines. On nine occasions in 1951 and early 1952, Holter & Glasscock collected samples that gave far from normal curves. Study showed that they were the decay curves of very complex mixtures of radioactive substances. The fission products remaining after an atomic explosion fit this description exactly...
...radios on the side to meet expenses. During the war he joined the FBI, was assigned to the important anti-sabotage unit which kept a watch on the Communist cell at the University of California's radiation laboratory in Berkeley, where basic research was under way on atomic fission. After the war, Velde went into Republican politics in Illinois' Tazewell County, was first elected to Congress in 1948. His FBI record helped his campaign...
...this quite straight in our minds," she said. "It is not what men discover that changes the structure of society. It is how men legislate upon those discoveries which change the structure of society . . . The discovery of nuclear fission has not changed, and will not solve, one underlying problem of the world today . . . Energy and matter, which we now know to be one, are both amoral. Man only is moral or immoral. We have only to reflect that if all the large nations of the world were led today by moral men, instead of immoral ones, [development of] atomic energy...
...Harvard, the eminent educator became chairman of his alma mater's chemistry department before assuming its presidency in 1933. In World War II, as chairman of the National Defense Research Committee, he bossed a $2 billion research program to develop radar, antiradar, various chemical warfare projects, and nuclear fission. Putting in some 250,000 miles of travel, bounded by Cambridge, Washington and Los Alamos, he deputized for Vannevar Bush, served as consultant for Major General Leslie Groves, was the No. I intermediary for scientists, generals and industrialists who helped fashion the Abomb. Since...
...basic principles were worked out long before World War I, but the popular vogue probably grew out of two great technical achievements of World War II. Nuclear fission convinced the public that "science can do anything." The German V-2 rocket proved that a man-made vehicle can climb briefly into space. The head of the V-2 project, Dr. Wernher von Braun, is still only 40 and is the major prophet and hero (or wild propagandist, some scientists suspect) of space travel. As a boy, Dr. von Braun wanted to go to the moon. He still does...
