...Given this manifestation of solar activity, our interest lies in the determination of any possible terrestrial influence," Andrews said. "The presence of huge magnetic fields in the sunspots results in their acting as howitzers to pour forth charged particles of matter into the interplanetary realm. If the earth is in the range of the howitzer, its atmosphere is the recipient of these particles, and, beyond doubt, electrical phenomena should occur there...
...rotation of the sun on its axis in a period of some 25 days prevents the earth's being constantly in the range of a sunspot or sunspot group, and so we look for the evidence of a terrestrial effect when a spot lies near the centre of the sun as seen from the earth. When this state of affairs is valid such terrestrial phenomena as auroral displays, magnetic storms, and effects on long distance radio reception should occur, for they depend upon the electrical conditions of the atmosphere; and indeed our expectations are fulfilled...
Except for the pontifical autobiography that the late John Hays Hammond wrote at the age of 80, U. S. mining engineers have been surprisingly reticent about their world-wide rovings, their climbs up high mountains and descents into the deep earth. Last week a successful mining engineer now little more than half Hammond's age offered a volume of reminiscence as informal as Hammond's was ponderous, less than half as long and twice as funny, and dealing with events that were as inconsequential as those that Hammond recorded were important. Saying he "would not be so brash...
...epitaph for as no man knows my motives dare now vindicate them. Let them and me repose in obscurity and peace and my tomb remain uninscribed until other times and other men can do justice to my character. When my country takes her place among the nations of the earth, then and not till then let my epitaph be written. I have done...
...Hess was the first man to see clearly that the cosmic rays were cosmic-that is, that they did not come from the earth or the atmosphere. Enthusiastic Austrians once called this mysterious radiation "Hess Rays," just as an enthusiastic U. S. scientist later called them "Millikan Rays." Cosmic rays, as almost everyone now knows, bombard Earth continuously from every direction in the sky. No one knew this when the 20th Century opened. About that time it was observed that some sort of radiation from somewhere was constantly ionizing the air in electroscopes. Some theorists thought the source was radioactive...
