...George Ellery Hale, director of the Mt. Wilson Observatory, writing in Scribner's Magazine (June), tells what is now known about sun spots. Sun spots are believed to be (though no astronomer is certain about it) regions of incandescent gas on the sun's surface, whirling with a centrifugal motion. Although they are really brighter and hotter than the most powerful electric light, they are so much cooler than the 'body of the sun itself, that they appear to us as dark spots. They move in very definite cycles of eleven years and one month. Starting...
...wild theories of their relation to terrestrial conditions have been advanced. They do seem to be of a magnetic nature and to produce electrical and atmospheric disturbances on the earth at certain periods. Professor Tchijewsky, a Russian scientist, has recently come out with a theory that at sun spot maxima, worldly affairs are excited and wars, revolutions, migrations, etc.. break out. He thinks he has traced definite cycles of such historical events in the 19th Century paralleling the sun spots. The purely fantastic character of this conjecture is obvious; the problem of the physical influence of the spots...
...follows: The photographic film (it can be used wet, direct from the developing bath) is held taut and curved in the form of a cylinder, like an old-fashioned phonograph record. Light, from an ordinary automobile lamp, is passed through a lens and concentrated in a small spot at one corner of the film. At the receiving station a blank film is formed into a similar cylinder. By a device known as a synchronizer, the cylinders at both ends are started simultaneously and turned at the same rate of speed. The light beam travels in a continuous line over...
...forth according to their intensity, making the slot wider or narrower. The light beam, passing through the slot, falls on the revolving cylinder, printing broader or narrower lines of light on the film. With each revolution the cylinder is jerked 1/65th of an inch to the right, and the spot traces another line exactly parallel. This interval was found the best for newspaper pictures, but the machine can be set for any degree of fineness or coarseness, according to the type of engraving to be reproduced...
...Samborski's slugging at the ball game yesterday was in the press stand, where Billy B. Van, comedian in "The Dream Girl" at the Wilbur Theatre, was broadcasting the story of the contest to radio fans through Station WNAC, the Shepard Stores. His witty comments drew to the spot a large circle of spectators, who chortled with glee when the comedian seriously made through the microphone such remarks as "Hammond knocks a foul into the grandstand.... It hits a man in an empty seat", and "The umpire calls a balk, Williams demands a recount... The umpire wins...
