...First Finder. Like a good scientist Dr. Compton thought it best to begin at the beginning: "In order to place the results of the recent studies of cosmic rays in appropriate perspective, let us recall very briefly their early history. It is well known how at the beginning of the present century. . . ." At the beginning of the present century Geitel of Germany, experimenting with a quartz-fibre electroscope, noticed that for no apparent reason the air in his instrument gradually became more electrified or ionized. Later experimenters discovered that thick screens of lead or water shut out some...
...veterinarian gave the dog an injection of glucose and a 50-50 chance to live, rushed it to the O'Haras' home in Pawtucket. There last week Sox, wasted from 20 to 6½ lb., was under constant care of two veterinarians and Mrs. O'Hara. Finder Kelley, more concerned with his creditors than with Sox's health, kept mum about what he would do with his $1,000 windfall...
Another report was that two radio engineers named Rodman and Dumont had helped Captain Clayton develop the ship-finder, using a thermocouple. Thermocouples operate on the physical principle that, if two small strips of dissimilar metals are made to form a closed circuit, minute changes in the temperature of the strips set up minute electrical currents, which may be amplified by vacuum tubes and measured. Astronomers use thermocouples to measure the temperatures of stars trillions of miles away...
...focus of a movable parabolic reflector, and to assume, when a peak of electrical activity was noted, that the reflector was trained on some strong source of radiation-such as a metal ship out to sea in the dark. If this is how the Signal Corps' ship-finder works, it differs in no essential detail from the infra-red "Fog-eye" developed by Paul Humphrey Macneil and successfully demonstrated two years ago (TIME...
...Harvey Harlow Nininger, Colorado meteorite expert, revealed discovery of a 700-lb. aerolite by a farmer near Hugoton, Kans. Buried a yard deep in the ground, it was the most massive aerolite ever turned up in that State.* Mr. Nininger bought the ponderous stone on the spot, and the finder hoisted it into his trailer, started hauling it to Denver where Mr. Nininger is curator of meteorites at the Colorado Museum of Natural History...
