Last week three young Carnegie Institution men, Drs. Merle Anthony Tuve, Lawrence R. Hafstad and Odd Dahl, through the Physical Review, offered atom crackers a new, manageable howitzer. (They had first mentioned that piece of laboratory ordinance when the Association for the Advancement of Science met in Pasadena last June. Although the scientists could see little of the machine's effect, they nonetheless gave a $1,000 prize to the ingenious young men.) Their machine consists essentially of a tesla coil under oil and a cascading cathode tube. The coil builds up an electrical potential...
...three hours, near dusk, a radio officer at the airport hears that the Akron is about to return. The lounging ground crew springs into action. A large cloth panel with the figures "63" is spread on the ground, tells Commander Rosen dahl the ground temperature. Another panel, striped, is spread several hundred feet "upwind" from the mooring mast and marked by two lantern-swinging grounds men. A smoke candle is lighted to show the direction of the ground wind. Presently there is a drone of engines from the east, then the wink of two white bow lights, two green starboard...
...with whom Counsel .Untermyer did most of his dickering is tall, big-toothed Gerhard Melvin Dahl, onetime (1910-12) commissioner of street railways in Cleveland. Although New York's two systems are figuratively autonomous, Mr. Dahl is board chairman of both because of B. M. T.'s large I. R. T. holdings. Because he is the biggest figure in New York's transit business and because he played so prominent a part in the Untermyer negotiations, observers believed that, instead of losing his job if and when the unification plan becomes an actuality, he may sell...
...Paper. Dr. Merle A. Tuve, physicist of the Carnegie Institution's department of terrestrial magnetism, read a paper worth $1,000, the annual Association award for outstanding address of the meeting. With three fellow physicists, Drs. L. R. Hafsted and Odd Dahl of Carnegie Institution and Dr. Gregory Breit of New York University, he worked for several years to develop a two-million-volt tube which produces X-rays equivalent to the gamma rays of 182 million dollars worth of radium. Laboratory significance : scientists by using these powerful rays may be able to burst the atom nucleus. Practical significance...
