...myth, that no change had been made since 1909, when the cork centre was introduced. When the New York Telegram, crusading against the "lively" ball, last week produced cross-sections of a 1919 ball and of a 1929 ball to show that the 1929 ball contains a layer of rubber not found in its 1919 ancestor, Julian W. Curtiss, Spalding president, wrote to the Telegram: "Let me assure you that the life of the ball has not been changed since 1920." He left the inference, satisfying to sticklers, that it had been changed between...
...third and outer blanket, the Heaviside layer, very little is known, and that only inferentially. Pressure 100 miles up is calculated to be 1/300,000 of the pressure at sea level, practically a vacuum. Highly tenuous though that upper medium is, it is nonetheless dense enough to burn up meteors by its friction. Like the lower atmosphere it carries electrical charges. Proof of that is the great heights from which the curtains of Aurora Borealis, an electrical phenomenon, hang. If Professor Goddard, or anyone else, can learn the exact nature of that high zone it is conceivable that man will...
Those few flyers who have been able to get seven miles above the earth have been at the top of the earth's atmosphere layer. They have been able to stay there only a few moments, for the temperature is 75 degrees below Fahrenheit zero and the air-pressure is one-eighth of what man is built to endure. Nor could the thin air sustain the planes or sufficiently burn the fuel...
Beyond the "atmosphere" is the "stratosphere," a rarefied layer extending 25 mi. further, where it meets the Heaviside Layer of tenuous, electrified gases off which, in theory, radio waves "bounce" from transmitter to receiver...
...university. While Oxford cannot boast of the yellow, strangling fogs which infest London and turn her days into hideous night, she can offer a specimen of a sort no less disagreeable to newcomers. For a few hours at least during these quiet winter days, a thick white layer is apt to fill the bowl which the Isis and the Cherwell have made between Cumnor, Boars' Hill, and Shot-over. The dome of the Radcliffe Camera, the spires and towers of St. Mary the Virgin's, Magdalen, Merton, and the Cathedral are lost in the lower reaches of this fog-bank...
