...knows yet where cosmic ray particles come from. A few may originate in rare solar "flares," but most of them come from farther space. The fastest particles pack an enormous punch, up to 1016 ev (10 million billion electron volts) of energy. To accelerate a flea to this speed, said Neher, would require all the energy released by a hydrogen bomb...
...what looks like a TV camera with a conventional lens, but instead of taking light in, the "camera" shoots light out, acting like a highly educated floodlight. The source of light behind the lens is a luminescent surface that glows brightly when struck by a hair-thin beam of electrons. The electron beam scans back and forth, covering the whole surface in a small fraction of a second. The spot of light that it creates is projected on the scene by the lens, scanning it like the beam of a small searchlight. There are no moving parts except electrons...
...Millikan, the first boss of modern Caltech, who discovered the cosmic ray and first measured the charge of the electron. Nobel Laureate Thomas Hunt Morgan unlocked the mysteries of the chromosome, and Richard Tolman helped prepare the way for the modern theory of chemical-reaction rates. Richard Badger's rule described the relationship between the vibration and size of two-atom molecules. Through his work on the red and yellow pigments of such plants as carrots and tomatoes, Laszlo Zechmeister has determined some of the molecular configurations that are effective precursors of vitamin...
...leader in basic research on tooth growth and structure, Dr. Sognnaes has made intensive studies of the enamel of teeth, using chemical analysis and the electron microscope...
...even more radical flat tube under development by General Electric Co. gets rid of the vacuum, and it has no electron beam either. It consists of a sheet of "electroluminescent" phosphor that glows when it is excited by an electrical voltage. The phosphor is sandwiched between a matrix of horizontal and vertical wires. If there are 500 running in each direction there will be 250,000 points at which wires cross. These intersections can be made to glow by impressing the proper voltage on the wires. If the voltages are changed rapidly, the spot of light scans the screen, forming...
