...lengths enough for all comers. Firstcomers, who had their pick, staked out their claims on the easy frequencies, the most readily exploitable wave lengths. Ultrashort waves (frequencies of 30,000 kilocycles and higher) were the wasteland. It was known that they were reliably effective only as far as the horizon, a paltry range for services which sought to blanket the whole earth...
...television engineers. But televisors cannot simply establish squatters' rights, they must compete before the Federal Communications Commission with other services that seek room for expansion (TIME, July11). Meanwhile the inventors and engineers are concentrated on the problem of stretching this narrow field, increasing its effective range beyond the horizon. RCA-NBC boosted its television transmitter to the top of Manhattan's Empire State Building, claims reliable reception for its experimental telecasts over a radius of 43 miles, receives reports of sporadic reception some 100 miles away...
...ultrashort waves do spray beyond the horizon. When they travel far, however, they become as shifty and unaccountable as ricocheting bullets, cannot be relied upon to hit any particular target. Radiomen are appalled at the cost of setting up a network of ultra-short-wave stations, piping programs from station to station by cable or ordinary short-range radio-relay links. Last week was announced the invention by RCA's Inventor Vladimir Kosma Zworykin of a system designed to eliminate such costly cables...
Computations by which navigators determine their position from sextant observations of the altitude (elevation above the horizon) and azimuth (true bearing by compass) of heavenly bodies may take up to 15 minutes. In airplanes traveling 200 m.p.h. such computations are out of date by the time they are made. The Navy's Hydrographic Office published tables last year covering latitudes of 30 to 39 degrees, from which navigators could check their position in a few seconds...
...practically at the point of saturation, which permits her no longer to receive further refugees without upsetting the equilibrium of her social structure." M. Bérenger cried: "The hunting of a man, confiscation of his property, a concentration camp beyond which there is only the graveyard as a horizon-all this is contrary to human dignity and can result only in the catastrophic disturbance of relations between nations!" Such language was not calculated to soothe Adolf Hitler, whose help would be most useful in getting Jews out of Germany. Already forbidden to take money with them, German Jews were...
