...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...

Fast moving electrons make an impression on a photographic plate as X-rays do, but Davisson's electrons were too slow to obtain such a picture. So he "felt" the pattern of his reflected beam by moving an electron collector around in the recoil region. Connected to an ammeter, the collector translated the strength of the electron beam at a number of points into measured electric current. The pattern having been thus patiently and ingeniously mapped out, it was seen to consist of true diffraction rings. Concluded the researchers: "Our experiments establish the wave nature of moving electrons with...

...long, it builds up solidly. Under the primary influence of the later Yeats--in particular, I think, of "The Second Coming"--Mr. Brown has tried for the compression and suggestiveness of symbolist poetry. The difficulties of such a technique are great. In stanza 4 the strained Apollo-Daphne pattern of symbols sticks out like a bad metaphysical conceit; while in stanza 5, the symbols are blurred, which in turn gives the lines an affected air of forced subtlety. But at once Mr. Brown returns to the simpler strain in which he is at his best...

...Hahn's fatal fascination had consisted of her skill at German cooking. Each contained ample traces of the favorite Hahn seasoning- arsenic and croton oil. By the time the corpses of four of Mrs. Hahn's former friends had been examined, a variation in the monotonous pattern of Mrs. Hahn's past finally appeared. This was a hardy sexagenarian named George Heis, for whom the only consequences of a late evening snack of beer, pancakes, spinach, arsenic and croton oil, prepared by Mrs. Hahn, was partial paralysis and indigestion. Still hale enough to be wheeled into court...

...winning fight in Cheyenne had not kept both of Publisher McCraken's hands busy. Between 1927 and 1932 he had bought and made daily tabloids of the weekly Newcastle News-Letters and Rock Springs Rocket. These followed the pattern of the Eagle: breezy style, plenty of comics, big, black type and Democratic politics. To keep his papers on their toes, Publisher McCraken made each local manager a part owner...
