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...
Probing deeper into the mysteries of the atom, Dr. L. R. Van Wert of the Graduate School of Engineering has devised a new method of investigating the atomic structure of metal alloys. The effects of pressures as high as 20,000 atmospheres on the speed with which certain alloys undergo agehardening are studied in his process...
...chemicals of earth it, like all plants, manufactures a colorless substance called proto-chlorophyll. Proto-chlorophyll accumulates in certain cells of leaves called chloroplasts where it comes in contact with carbon dioxide in the air. When the sun is shining a molecule of proto-chlorophyll, stimulated by an atom of magnesium which holds it together, absorbs four quanta of energy from a sunbeam. The extra energy enables the proto-chlorophyll to attract carbon dioxide, kick off the oxygen which it does not require, absorb the carbon. At that instant the colorless proto-chlorophyll becomes chlorophyll and makes the grass green...
...higher than normal concentration (one part in 4,500) in the Dead Sea, the Great Salt Lake, the sap and wood of willow trees, borax deposits. The hydrogen of honey, coal benzene and kerosene was found comparatively rich in D. But in the Sun's atmosphere only one atom of D in 100,000 of hydrogen appears to be present...
...chemists, according to Dr. Urey, the greatest importance of heavy hydrogen is that exchange reactions involving hydrogen can be traced, since the heavy and light atoms are as distinct as red and green. To physicists, the heavy nucleus, the deuton, has proved an invaluable atom-smashing projectile. To commercial chemists, interaction experiments between hydrogen and heavy hydrogen at low temperatures have offered hope that the cost of synthesizing alcohols and ammonia may be drastically reduced...
