...went the speech-while outside the long lines of police, hands joined, resisted and almost sank beneath wave on wave of mob. The priest promised a (roughly) 60? dollar, praised the President for having the "intestinal fortitude" to fight Morgan. At a mention of Al Smith (see above) the crowd jeered, booed...
...Foreign Commissar, left their four-room apartment in a converted garage with her grave, acutely class-conscious 16-year-old son Mischa. Together they hurried to the Soviet Commissariat of Communications. Proud as punch. Soviet technicians placed before them a Russian-made telephone, bade them talk by short wave radio to Comrade Litvinoff, seated in the Oval Room of the White House. "Millions of Americans will listen to you on their radio networks!" cried the chief Red technician proudly. "Say whatever you wish...
Eight years ago an astute French theorist named Louis de Broglie enlarged and vastly complicated the field of subatomic study by endowing orbital electrons with the properties of waves or pulsations. Erwin Schrodinger then began work which led to a potent development of this idea. He replaced the classical equations for electron motion with new differential equations similar to those which describe the wave motion which constitutes light and sound. Thus the atom is conceived as a positive nucleus wrapped in a throbbing field of negative electricity. To expound these ticklish ideas to U. S. scientists slim, smallish, pleasant-spoken...
...Heisenberg: "You know what they call the new physics in Germany? They call it the 'Boy Physics.' " Werner Heisenberg at 21 had distinguished himself by studies on the Zeeman effect (splitting of spectrum lines when light comes from an electromagnetic field). Independently of the de Broglie wave mechanics, he devised an abstruse mathematical description of electronic behavior which he called "matrix mechanics." He saw the necessity of a wave concept as well as anyone else, but he followed the Newtonian principle that hypotheses should be avoided. In the light of wave mechanics alone, electrons lost their individualities, melted...
...Wave mechanics and matrix mechanics are different mathematical expressions of the same theory. A third description of electron behavior, which strengthened rather than contradicted the other two representations, was contributed by last week's third prizewinner, Cambridge University's brilliant young Dr. Dirac. Also, long before lightweight protons or "positrons" were experimentally observed by Caltech's Dr. Carl David Anderson (TIME, March 6), Dr. Dirac had declared such particles to be required by mathematical necessity. But this shy, angular youngster with small Wack eyes and small black mustache, already a big frog in the subatomic puddle, made...
