TIMES change. Before the war, what was missing from the American scene was "a good five-cent cigar." One of the Gods of the present generation is Science, and the efforts of Wells, Durant Eddington, Jeans, and others to explain what the new theoretical science means left unsatisfied the persistent statement that "what this country needs is a good two-dollar explanation of Relativity...
...Brown's exposition each share of common stock was "worth" on December 31, 1936, about $31. Yet Mr. Brown's report points out that the company in March 1937 was able to sell 100,000 shares of its common stock at $100 per share. Let Mr. Brown explain how he was able to sell stock which he says was "worth" $31 per share for a consideration of $100 per share...
Even Heavyweight von Helmholtz was unable to explain what made the simplest wheels of a musical composition go round. But ever since his time rubber-gloved scientists have been trying to get music and musicians into test tubes and under microscopes. Today's No. 1 and 2 musical microbe hunters are flute-playing, Einstein-disputing Professor Dayton C. Miller of Cleveland's Case School of Applied Science, and Iowa State University's dapper, white-haired Dean Emeritus Carl Emil Seashore. While Physicist Miller has succeeded in taking up where the doughty von Helmholtz left off, Psychologist Seashore...
...field. The lines of force in these fields were not arranged in Newtonian straight lines but in curves. After curved fields in space came waves of energy. The wave theory of light, which had been opposed by Newton, was picked up again because it was the only way to explain certain phenomena-for example, the diffraction rings produced when light passes through a small aperture. Before electro-magnetic waves (e.g., wireless waves) were ever demonstrated experimentally, Maxwell distilled them out of his mathematical equations, then showed that their velocity was equal to the velocity of light. Therefore, light appeared...
...discussion of the Quantum Theory. Max Planck provided the first experiments and Einstein the early theory which regards energy as released and received not in continuous flow but in separate little bundles called quanta. A quantum of light is called a photon. Einstein used early Quantum Theory to explain photoelectric action-the ability of photons to knock electrons out of metals...
