...lonosphere Observatory of the University, after a four-year shutdown, has resumed its radio investigations of the little-understood deep blankets of atomic particles which surround the earth's atmosphere a hundred or so miles from the ground, and which enable long-distance wireless communication...
Back in radio's early crystal-set era, gloomy prophets spooked telephone stockholders, predicting that the wireless voice would make wire lines relics of an obsolete communications system. Few prophets foresaw that radio would vastly increase the use of wire services as radio pipelines, and nobody would have guessed the telephonic congestion caused by two radio riddle programs last week...
...then active: the Navy, private companies engaged in ship communications and the small group of early-bird amateurs. Anybody who applied got a license. Its issuance was part of the job of the Secretary of Commerce, a very small part until 1920 when KDKA (Pittsburgh) applied for the first wireless telephone broadcasting station license. The Secretary granted it a wave length of 360 meters, continued issuing other stations licenses on the same wave length until...
...soprano named Margaret Kubatzki. Soprano Kubatzki, making her official Covent Garden debut in a role previously sung by the eminent Kirsten Flagstad (Senta in Wagner's The Flying Dutch-man), created a sensation. Said Conductor Beecham: "One night last October I was turning the various knobs of a wireless ... I heard a magnificent voice. . . . When I went to Germany to make records of the Magic Flute I enquired of every eminent German musician I met as to what he knew about Kubatzki. None of them even knew the name. I rang up every opera house in Germany until...
...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 to be an electro-magnetic wave. This was one of the greatest achievements in the history of science. Physicists speak of Maxwell...
