...with a parlor game: a modern variation of famed tiddledywinks. An ashtray is placed on the floor. The players (any number from two to eight), equipped with dimes and quarters, squat. In turn, they use their quarters to try to flick their dimes into the ashtray in a graceful arc. It is a game requiring firm thumbs, keen eyes. It was invented by that skillful player, John Cowles, 29, who is to Des Moines what a dynamo is to a powerhouse...
...shuttle back and forth . . . across Nicaragua, enjoying a fairly adequate food supply, tapping rich agricultural sectors, and passing rapidly from point to point; whereas the American troops, to cover this same region, and maintain intact their line of communications with Managua and Leon, must swing over an arc half again as long...
...latest measurements of the cosmic ray (TIME, November 23, 1925) prove it to consist of definite bands of color, like the light from a Cooper-Hewitt mercury arc, but the spectral region in which the bands occur corresponds to frequencies 100,000,000 times greater than those emitted by the Cooper-Hewitt arc. Having measured the ray, Dr. Millikan sat down to figure out its importance. He turned to Einstein's theories. He found, using the Einstein equation (M C 2-E), that the most conspicuous band in the cosmic ray spectrum is probably the same band that would...
From the Lesser to the Greater Antilles the flyer took the tiniest hop of his trip. San Juan, Porto Rico was only 90 miles away. Col. Lindbergh doubled the distance by flying out of his way in a sharp arc to give natives of St. Croix Island a glimpse of him in passing. At San Juan he had three notable experiences. The first was an orderly and properly policed landing. The propensities of crowds on three continents to smash police lines wherever formed around a Lindbergh terminal was checked in Porto Rico. Six hundred native police, local militia...
Sending Set. This consists of: 1) an arc light of brilliant and steady glow which throws a beam of light through 48 apertures arranged spirally in 2) a large disc that revolves 18 times a second. The light thus brushes speedily across an object or performer and is reflected back upon the third important element of the device-photo-electric cells. The reflected light modifies the electro-magnetic waves passing through the tubes. With light waves rapidly translated into electro-magnetic waves, there remains no problem of sending the electro-magnetic waves through the air. Radio transmission, which changes sound...
