...Instead of automobiles, however, it will handle streams of speeding electrons. It is Stanford University's linear accelerator, the newest tool in one of the newest and fastest-growing disciplines of science, high-energy physics. When it achieves full power and goes into operation this fall, the largest atom smasher in the world will give man a closer look at the mysterious subatomic world and its host of newly discovered particles...
...chemistry exact and predictable: they have made the first direct measurement of the minimum energy required to cause one of the simplest chemical reactions known to science. An absolute minimum of one-third of an electron volt is needed, they discovered, to split a hydrogen molecule into two hydrogen atoms and to combine one of them with a deuterium atom to form deuterium hydride. An addition of any less energy and the reaction will not occur...
Rainbow of Colors. To measure this tiny quantity-less than a millionth of the energy needed to split the nucleus of an atom-the scientists devised an ingenious technique. Light from a 200-watt mercury vapor lamp was focused on a diffraction grating, which, like a prism, broke up the beam into its constituent rainbow of colors, its separate wave lengths of light. By rotating the grating to a carefully calculated angle, the scientists were able to reflect light of a single, specific wave length at a target. Knowing the wave length, they were able to determine precisely the energy...
...White, this suggested that the wave length of light used in the previous exposure provided the minimum energy needed to cause the reaction. They then determined the energy carried by a photon at that wave length and calculated how much of it had been imparted to the deuterium atom when the deuterium iodide molecule was split. Their result: one-third of an electron volt...
...devices on China's perimeter. Drone planes, high-flying U-2s and satellite cameras record roads, railways, steel mills, oil wells, nuclear plants, missile ranges and troop movements. U.S. Government analysts early spotted China's gaseous diffusion plant at Lanchow, the plutonium reactor at Paotow, and the atom-bomb test site at Lop Nor in the Taklamakan wastes of Sinkiang. They have predicted well in advance the timing of all three Chinese atomic explosions...
