...Manhattan, Davisson and his colleagues decided to find experimental proof of the de Broglie theory. If a beam of electrons could act like a beam of light, it should show a pattern of concentric rings when diffracted through a crystal. But the low-powered electrons (100 volts) which Davisson was using would not go through a crystal. He knew, however, that a beam reflected from the topmost atoms of the crystal structure would make a pattern similar to that made by a beam passing through. So he decided to explore the recoil pattern of electrons bouncing off the crystal surface...
This technique has become of great practical importance for investigating crystal structures. Meanwhile, with the impetus provided by this experimental confirmation, the wave theory was developed by de Broglie. Heisenberg, Schroedinger and Dirac into the monumental theoretical structure which is modern quantum Mechanics. All these theorists are Nobel Prizewinners...
...immediate cause of her death; 2) an ovary to examine the tumor which mysteriously developed a few weeks ago, caused her to waste away, reduced her resistance to the pneumonia; and 3) her strange, ineffective brain. Then she was buried with a fresh corsage of gardenias and the crystal necklace which her constant fiance, a jewelry salesman named James Burns, gave her. Her mother, Mrs. Peter Miley, whose second husband, like her first, is a structural iron worker, had kept a meticulous diary of her daughter's 2,096 days in bed. The doctor in the case, Dr. Eugene...
Sold to a standstill in the six-week slide that lopped off more than a year's gains, the stockmarket steadied last week, then rebounded feebly. By now it was crystal clear that whatever gave the market the first push downhill it would not have slid so far on a false alarm. But the market's barometric value is limited. It seldom indicates how much it will rain, or how long...
Manhattan is proud of its clear, sea-born air, which, especially in the first days of fall, Manhattanites find as heady as a new vintage. Manhattan is also proud of its nightspots, where the atmosphere, though equally shady, is not so crystal-pure. When Repeal put an end to Prohibition's frowzy summer, Manhattan's undercover nightclubs, legally uncorked at last, popped and fizzed into a boom-de-ay of business gaiety. When the egregious Billy Rose converted a theatre into his Casino de Paree, where hundreds instead of scores could wine, dine, dance and watch a show...
