...astronomer, Ole Roemer, who measured the variations in eclipse times of Jupiter's satellites according to Earth's distance from that planet. His calculation was only about 3% too high. First terrestrial measurement was made in 1849 by Armand Hippolyte Louis Fizeau of France, who passed a beam of light through the teeth of a spinning cogwheel. The light struck a mirror, bounced back to the wheel. The wheel had been timed to move just enough in the brief interim for the teeth of the wheel to intercept the light as it was reflected. By timing the revolutions...
Trip 6 got away safely from Medford, Ore. after midnight, with seven radio ranges, their beams running in four quadrants, to guide him to Oakland. But at Medford, Stead had already made his first blunder. He failed to fill his gasoline tanks. From Medford, on instruments, against a heavy headwind and an hour behind schedule, he went down the south leg of the Fort Jones range, passed the Red Bluff localizer, reported that the Sacramento range was drowning out the Williams beam (which ground stations reported was operating without interference). Then, for almost an hour, Trip 6 was silent...
...fact that the U. S. has quietly entered the short-wave news propaganda battle. Every day in the week for the past year and a half, NBC's 25-kilowatt W 3 XL, its power stepped up to the equivalent of some 150 kilowatts by a directional beam antenna, has sent in the direction of Germany's 5,000,000 shortwave receivers an hour of news, music and Americana calculated to reach Germans between eight and nine o'clock at night...
...attention among scientists who want to see ever smaller & smaller things. The magnification of ordinary microscopes is limited by the wave nature of light. Some things are so small that they slip through the meshes of the light rays like BB shot through a tennis net. Instead of a beam of light the electron microscope utilizes a beam of electrons, which have wave lengths thousands of times shorter than visible light but also make impressions on photographic plates...
...short-wave broadcasting power is the 40 kw. of General Electric Co.'s station W2XAF at South Schenectady and Westinghouse's station W8XK at Saxonburg, Pa. But General Electric is building a 100 kw. transmitter to improve the service it sends on directional beam to South America. Germany lists its short-wave transmitter that operates from Berlin's Haus des Rundfunks at 40 kw. Great Britain's Daventry, with top power at 50 kw., sends its short-wave voice round the world. The Netherlands has two 60 kw. stations at Hilversum, which operate with unique beams...
