...three isotopes, is comparable to a lot of lemons, oranges and grapefruit in a paper bag.' Dr. Bainbridge knew the weight of the whole, also the average weight of each piece of his "fruit," but (he assumed) not the weight of each individual piece. So he propelled the neon atoms through the chamber with an electric force, strong enough to blow the "bag" to pieces, ionize the atoms. Two huge electromagnets created a powerful magnetic field, which, like gravity pulling the fruit to earth, defleeted the course of the ionized atoms. Dr. Bainbridge snapped a picture. The lightest isotopes, like...
...size and shape of an invisible barn might be determined by throwing a million baseballs at it and studying the number of balls which hit it and the angles at which they bounce off. That is the way physicists have determined the structure of the atom. Pellets have been radium particles, X-rays and, lately, cosmic rays. Inability to control available ammunition has been the great handicap...
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...
...similar jolt of energy would bolt from a light-weight atom at the instant it acquired energy by merging with another light atom or by accumulating raw energy from circumambient space...
...Anderson's 50,000,000-volt rays prove him right, reasoned Dr. Millikan last week. He figures that at the interstellar birth of a helium atom 70,000,000 volts would be released; for oxygen 116,000,000 volts; for silicon 216,000,000 volts; for iron 450,000,000. Those are, he is convinced, the only elements floating between the stars in sufficient quantities to produce radiation effective on earth. Radiations from helium, oxygen and silicon do not reach the earth because the atmosphere damps them. It is iron's radiation which Dr. Millikan believes his adherents and opponents...
