Right down the middle went the third, Hester. She married and divorced Ellery C. Huntington Jr., All-America (Colgate) football star and Wall Street lawyer, married and divorced Sculptor Oscar Fulton Davisson Jr. Among such liberal minds as inhabited conservative New Canaan, Conn., Hester was in the forefront. Still within the pale, still listed in the Social Register, Hester was not Red, but a delicate pinko...
...idea of electronic magnification has been a live subject in physics for a decade. Foundations of the technique were laid down in Germany in 1926-27. Other work has been done in Belgium and in the U. S. by Dr. Clinton Joseph Davisson of Bell Telephone Laboratories, who won a Nobel Prize in physics last year for experimentally demonstrating the wave nature of electrons. Some years ago, Astronomer Francois Charles Henroteau of Ottawa's Dominion Observatory suggested that an electronic telescope (converting feeble starlight into electric current by means of photoelectric cells) could be built which would equal...
...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...
Last week the Swedish Academy of Sciences reached back ten years in atomic history, back to the experimental demonstrators of the wave nature of electrons, awarded to Clinton Joseph Davisson and George Paget Thomson this year's Nobel Prize for Physics. Each will receive about $20,000. Said dark, lantern-jawed Dr. Davisson, already much honored for his researches: "I am suffering from a bad case of stage fright...
