...Hickman still, the hot surface carrying the distillate and the cold condensing surface are in the form of concentric, vertical cylinders. The vacuum is about one-millionth of atmospheric pressure. General Mills joined Eastman Kodak in erecting a pilot plant, which was put into semi-commercial operation a year ago. Its Vitamin A capacity is 60 billion units a week. This output is expected to be trebled by two stills of improved design now under construction...
...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...
