Devising cars of the future
Mr Charles F. Kettering, president of the General Motors Research Corporation, is also actively connected with many other great industries in America. "Why must a man get out into the mud to crank his car?" Kettering asked himself. And out of that question came a revolutionary system of starting, lighting and ignition for automobiles. ‘‘One thing you can be sure of, the car of the future is going to be as much better than the car of to-day as the car of to-day is better than an ox-cart. Not everybody believes that. There are lots of folk with ox-cart minds." Kettering aims high, like the boy at the moon. "First of all, you've got to form the habit of thinking about problems audaciously, even extravagantly."
Sails, clouds reflect sound waves
There is a story told of a sailor who went aloft to reef the sails of a vessel far out at sea and reported when he descended that he had heard the sound of bells faintly but clearly. They were being rung for a celebration, he was sure. The captain knew that the ship was far from land. But he had a liking for curious things so he entered the story in the ship’s log. When he reached port he found that there had been rejoicings in a coast town, where all the bells had been rung lustily and long. The explanation proved simple enough. The mainsail, blown out by the wind, made a fine collector and focus of sound. Probably the sound waves of the bells were also reflected from the clouds, which were plentiful that day. Clouds are first-class sound reflectors, as can be told from the rolling echoes in a thunderstorm. The unequal surfaces and varying distances of the cloud forms repeat the echo doubly and trebly. At sea the thunder sound is flung by the clouds to the sea and back again, so that tremendous echoes are produced and prolonged. — ODT, 1.9.1924
