...story concerned University of California's Ernest Orlando Lawrence, No. 1 U. S. experimenter in artificial radioactivity, whose 85-ton electromagnet frequently makes scientific news. Solemn young Dr. Lawrence would be horrified to find himself associated with the "death-rays"' of lurid pseudoscience. Actually he was only protecting himself and hi's co-workers from the effects of a beam of 10,000,000 neutrons a second generated with the help of his electromagnet for use in straightforward atomic experiments...
Microanalysis. By means of capillary tubes which require microscopes to tell when they are properly filled and a tiny iron-filled glass ball agitated by an electromagnet to stir the contents of the tiny glass vessels, Drs. David Glick and Gerson Ravinson Biskind of San Francisco made micro-analyses of microscopic bits of human tissue. Thus they learned that the middle part of pituitary gland contains Vitamin C (found in oranges, lemons, tomatoes, peppers, spinach) in more concentrated form than any plant or other animal tissue. The fore part of the pituitary, the adrenals and the ovaries also contain heavy...
Artificial Radium. By means of a powerful electromagnet Professor Ernest Orlando Lawrence of Berkeley can in ten hours' operating time instill as much radiant energy into a speck of common table salt as $2,500 worth of natural radium contains. The chief difference is that whereas natural radium, a deadly poison, will retain its radioactivity for thousands of years, radioactive table salt will lose all its potency within a few hours. During the period of its radioactivity, however, such table salt may do as much medical good as natural radium, and probably without harmful effects...
Radiant Copper. Dr. Ernest Orlando Lawrence, 33, wears octagonal spectacles and harries the atom with an 85-ton electromagnet in a ramshackle old building on the University of California's campus. Dr. Lawrence and his associates have done the most intensive work in the U.S. on artificial radioactivity. Lately the young physicist succeeded in inducing radioactivity in sodium. Since common salt contains sodium, the prospect immediately arose of injecting harmless but radioactive saline solutions into the human body as a cancer remedy. Few weeks ago Dr. Lawrence was appointed a research consultant of Columbia University's Crocker Institute...
...polarized by a Nicol prism, then sent through a cell containing carbon disulfide, a second cell containing a water solution of any substance to be tested; lastly through a second analyzing Nicol prism. Each of the two cells is surrounded by a coil of electric wire which becomes an electromagnet. The coils are so wound that the swings of the magnets are in opposite directions. To operate, the Allison device is so set that, with the magnets not working, the beam of light passing from the spark through the two cells and mirrors is at a minimum. Then...
