Eight of the last ten Nobel physics awards have gone to atomic researchers. Stern's and Rabi's awards were for studies of the atom's nucleus-the core of protons and neutrons...
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...
...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...
...mechanism is not designed to bridge the gap between these two extremes. As an alternative, the bankers advance the "key country approach." Most of the world's trade, they argue, is carried on in pounds and dollars. Therefore, the dollar-pound rate should first be stabilized, providing a nucleus to which other currencies could anchor at proper levels...
...more or less won in A.S.F. plans. The Army will give most consideration to the length of a man's service, will also consider his age and the number of his dependents. But the Army is going to keep enough well-seasoned troops to form a good-sized nucleus for every outfit...
