...Defense. The best: the U. S. fleet in action, with battle planes and bombers swooping down from the sky. Other good exhibits: U. S. Indian arts & crafts (TIME, March 6); a Federal Theatre offering such Living Newspaper hits as .... one third of a nation . . . , such documentary films as Pare Lorentz' The River...
Ecce Homo (Sat. 7:30 p. m. CBS). Documentary Film Producer Pare Lorentz (The Plough That Broke the Plains and The River) does a documentary radio script on unemployment for Columbia's Workshop...
...famed Michelson-Morley experiment of 1887, in which perpendicular beams of light were raced against each other, seemed to show that a light-carrying ether pervading all space did not exist. Fitzgerald, Larmor and Lorentz shored up the collapsing ether-concept by showing-theoretically-that a moving body must contract slightly in the direction of motion, that a moving clock would therefore slow down. Though imperceptible except at speeds approaching light's velocity (186,000 mi. per sec.), these changes would affect a Michelson-Morley apparatus just enough to cancel any possible observation of the ether-drift-by altering...
...Einstein's Relativity (1905-15) the ether was discarded as an unnecessary hypothesis. The Fitzgerald-Larmor-Lorentz effects were incorporated into Relativity theory, not as a consequence of absolute motion through a stagnant ether but as an effect of relative motion. If two observers are moving relative to each other, each one would find, checking by his own timepiece, that the other's clock was running slow...
...years the scientific world has waited for experimental demonstration of the Fitzgerald-Larmor-Lorentz effects. That demonstration was historically furnished last week at the meeting of the august National Academy of Sciences in Washington. The physicist who furnished it was Dr. Herbert Eugene Ives of Bell Telephone Laboratories. For "clocks" he used (at Einstein's suggestion, made in 1907) glowing particles of hydrogen gas. In such particles the frequency of energy oscillations determines the wave length of the emitted light, just as the oscillation frequency of a radio transmitter determines the length of the radio waves. When his particles...
