...been nothing less than remarkable. . . ." Mrs. Coolidge and John Coolidge laughed and waved. Then the locomotive snout sneezed, the wheels began turning and the Coolidges, standing on the back platform of the Washington train, watched the Rapid City station turning into a tiny light spot in which molecular faces peered and electronic fingers wiggled the West's farewell. CT Reporters who traveled east- ward with the President remembering the trip west in June, were impressed with the improvement in his appearance since that time. Then his face had been grey with presidential pallor, etched with executive anxiety...
...shadows of Harold Lloyd and Gloria Swanson, the chemists admired cinematic views of chemical wonders. A strip of animated drawings designed and presented by the General Electric Co. projected the electron theory of atoms into visible action, showing protons and their spinning satellites moving about to form molecular cubes, circles, chains, polymorphs...
...invention, the "window." This constituted a vast improvement upon the aluminum disc of earlier experiments. It was a sheet of nickel 1/2000 of an inch thin and three inches in diameter, supported against the 100-pound suction of the vacuum tube by skeleton struts of molybdenum. The molecular structure of nickel is such that molecules of air (oxygen, nitrogen) cannot pass through it, though it offers a minimum of resistance to those billionth parts of molecules, electrons...
...cathode, they raced off down the 12-inch exit passage of the tube until, when they reached the "window," they were going some 150,000 m.p.s. (four-fifths the speed of light). Their volume was virtually undiminished as they shot through the thin nickel foil and out into heavy, molecular air, where their effects were at once visible and startling...
Hottest Flame. Dr. Irving Langmuir of the General Electric Company described his discovery of a flame hotter than hydrogen burning in oxygen (oxy-hydrogen). He made atomic hydrogen burn in an atmosphere of molecular hydrogen. His hydrogen blowtorch melted tungsten wire like an icicle, indicating that its heat was at least 7,000° F. Playing on a sheet of chrome steel the flame left molten pools behind it. Significance: steel girders could be welded silently instead of noisily riveted;* the welds would not (as when an oxyhydrogen flame is used) be oxidized and thus weakened, they would be annealing...
