...lines recorded on photographic film. This apparatus permits the position of the diffraction lines to be measured with great accuracy and rapidity, and is proving a valuable tool in the determination of the distances between the atoms in metallic crystals. These distances are of the order of the hundred millionth part of a centimeter and may be measured with an accuracy of one part in ten thousand...
Taken in brilliant flashes of light of as brief a duration as one one-millionth of a second, both still and motion pictures will be shown. Professor Edgerton will exhibit the equipment and explain the technique he employed in this particular branch of photography...
About the same time in Aberdeen, Physicist George Paget Thomson, able son of Sir Joseph John, obtained the same result by a different method. He used much more high-powered electrons, around 50,000 volts. These were able to penetrate the crystalline structure of a film of metal one-millionth of an inch thick. After emerging they were still strong enough to impress a photographic plate, and Thomson obtained the first pictures of diffraction rings created by electrons...
...later wrote, "I began to wonder how the world must appear to a ladybug: what the sensation would be if my six feet of height dwindled down and down until I was hardly a quarter of an inch long; if I shrank to a thousandth, a ten-thousandth ... a millionth of my present bulk. Like Alice, I began to feel I was 'shutting up like a telescope...
...seven-millionth visitor had his ticket punched at the Paris Exposition of 1937 last week and experts agreed it was rapidly reaching historic rank with the great French expositions of the past. Greatest of these was Paris 1900, attended by thirty-nine millions before closing day. but a worthy successor was Paris 1931 with thirty-three and a half millions. On May 23 only four pavilions were ready when Paris 1937 was "inaugurated" by sad-eyed, droop-mustached French President Albert Lebrun, but last week 160 pavilions were complete and the Exposition was all but finished. Wiseacres agreed that...
