...final energy of millions of electron volts achieved by the projectiles equals the sum of the energies of all of the separate pushes...
Previous-lightning measurement has relied mainly on the oscillograph, which records the changing intensity of a bolt by means of an oscillating electron beam playing on photographic film. The fulchronograph is not only cheaper to use, says Westinghouse, but furnishes a clearer lightning picture...
...weighs 238 units.* The barium atom weighs 137 units. Since the barium could have originated only as a fragment of the big uranium atom, it was logical to suppose that the latter had cracked asunder, in two nearly equal parts. The release of atomic energy was 200,000,000 electron-volts. Heavy atoms had been "chipped" before -that is, forced to throw off small particles like neutrons-but this was the first time they had been cracked...
...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...
...last week was a picture taken by Professor L. C. Martin of London's Imperial College which showed a germ called Micrococcus flavus magnified 16,000 times. Last week in Richmond, Dr. Vladimir Kosma Zworykin of RCA Manufacturing Co. showed fluorescent-screen projections, made with his electron microscope, of tungsten crystals in which the molecules themselves could be distinguished in the molecular structure...
