...more successful device is the use of the voices of what seems like hundreds of individuals. Each voice, in the inflection of its own part of the world and in the jargon of a particular martial trade, gives one molecular view of the campaign. A Brooklyn tankman tells of his disgust when his tank runs out of gas, a Canadian describes the hideous fighting around Caen, a Royal Navy man admits his road sickness when his assault craft is trucked cross-country to the Rhine, a Negro cook tells how he learned to fire a bazooka at Bastogne, a primly...
...technique for molecular photography was originated by famed British Physicist Sir William Lawrence Bragg (TIME, Oct. 3, 1938), pioneer in the X-ray study of molecular crystals. He found that X rays, when diffracted by crystals, provide clues for calculating the pattern of atoms in a molecule. Using this information, he developed certain films, made of light and dark bands, which, when superimposed on the X-ray picture, make the atomic pattern visible. By enlargement of such a photograph, a molecule can be magnified 250,000,000 times...
...Molecular Beam. Stern and Rabi tackled the question: what holds the nucleus of an atom together? Its protons have positive charges which repel each other, yet the nucleus as a whole possesses a magnetic force that keeps them from breaking loose. Nuclear magnets are so small that for a long time no one knew how to measure them. But at Hamburg, where Rabi worked with Stern as a graduate student, Stern discovered...
...developed a "molecular beam" consisting of a stream of molecules shot through a very fine slit into a vacuum tube. In the empty tube, each molecule traveled in a straight line. When it was subjected to a magnetic field, a molecule's magnetic "moment" or force could be gauged by the extent of its deflection from a straight course...
Rabi, carrying these studies further, found the molecular beam much more helpful in studying the structure of an atom than an atom-smashing machine, whose use he likens to studying the Taj Mahal by dynamiting it and considering the fragments. By his method, Rabi learned, for example, that the deuteron, the simplest known nucleus, revolves like a football spinning end over...
