...first time, Dr. Millikan will use a new, streamlined cosmic ray counting apparatus. It is a light structure of four shelves, enclosed within an oval framework about three feet long, covered with black cellophane to keep out light. The two upper shelves in the black football each contain two Geiger counters, or ionization tubes which detect the arrival of cosmic ray particles. On the shelves below the counters are eight radio tubes. Connected to the counters and tubes is a light, compact short-wave radio transmitter with an aerial. When the apparatus is attached to a balloon and sent aloft...
Eighteen months ago the trust-busting division of the Department of Justice got its ears pinned back by crusty Federal Judge Ferdinand A. Geiger. When he found out that the Department was quietly discussing a consent decree with big finance companies and automobile manufacturers while a grand jury at Milwaukee was mailing an anti-trust investigation of motormakers' financing relationships, he denounced such shenanigans, summarily discharged the grand jury...
...particle, the neutretto-similar in mass to the barytron but having no electrical charge. The existence of neutrettos has not been proved. But in Chicago last week Physicist Francis R. Shonka of the University of Chicago reported high-altitude cosmic-ray experiments, in which he juggled various arrangements of Geiger-Muller cosmic-ray counters and selective lead shields, obtained evidence of something which he took to be electrically neutral particles of high penetrating power...
...first hearing of the suit in Milwaukee, Federal Judge Ferdinand Geiger was so outraged at learning that consent decrees were being arranged on the side that he tossed out the case...
...past four months physicists of the National Bureau of Standards at Washington have been sending clusters of small sounding balloons to great heights in the upper air. Purpose: cosmic ray research. The balloons carry Geiger-Müller cosmic ray counters, barographs, automatic radios which send signals to a ground station every 15 seconds, recording the altitude (in terms of air pressure) and the intensity of the cosmic bombardment. Last week Drs. L. F. Curtiss and A. V. Astin reported that one cluster of six balloons had reached the remarkable height of 23 miles (about 120,000 ft.). This...
