...hundred-ton cyclotron, one of the most powerful atom-smashers in the world, will be on view. In addition the visitor may see the new indoor wind-tunnel for testing airplane design; the new electron bombardment furnace, producing temperatures half as hot as the sun; the 100,000 - volt storage battery, most powerful in the world; the high-frequency radio equipment making automatic records of condition in the ionosphere; experiments which have led to a new theory of mountain formation; and many other laboratory features...
...Atom Smasher, a working model...
...venerable, rich American Philosophical Society in Philadelphia last week, grey, gentle Astronomer Henry Norris Russell of Princeton (see p. 58) explained what he considers the most reasonable modern theory on this question. The theory was worked out mathematically by Dr. Hans Albrecht Bethe of Cornell, a brilliant analyst of atomic behavior. Dr. Bethe sat down to figure out what atomic reactions would occur often enough to be important in the sun's energy economy, yet not so often as to use up the supply of some important ingredient in a hurry. He found that, at temperatures above...
...complete cycle withdrawing and returning a carbon atom to circulation requires more than 52,000,000 years. But such an enormous number of cycles are going on all the time that they keep the sun stuff...
...grounds of the Carnegie Institution of Washington stands a circular, domed building which looks like a modest astronomical observatory. It houses no telescope but a powerful atom-smasher, one of the two biggest in the world. The other is being readied at East Pittsburgh by Westinghouse Electric. Last week, after years of planning and construction, the Carnegie monster started its first test runs, hurling streams of protons (nuclei of hydrogen atoms) into a quartz plate at 5,000,000 volts...
