...would be interference, hence black lines and light fringes visible in the instrument. With this second result, it would be apparent that something impeded the light going in one direction-the movement of the earth (as the Einstein theory foretells would be the case) or the drift of the ether (according to the ether drift theory...
...were still provisional-that work was to go on for another month or two. But in no experiment so far had the beams going in opposite directions returned to the interferometer simultaneously. Every time there was interference, light fringes and dark lines supporting both the Einstein theory and the ether drift theory. More accurate observations are still to be made, but Mr. Michelson said in conclusion, referring to Einstein: "There is no question that the tests furnish another striking confirmation of his brilliant work...
Trash readers, comic-strip fanatics, crossword puzzlers, gum-chewers are satisfied by the noises which may be transmitted to them over the ether. But even in their case, and though they delight in listening in on Presidential speeches, football games, ball games, jazzy funnymen, first aid lectures, bed-time stories and advice to mothers, their interest is thus aroused in their newspapers. They delight in reading what they have heard. Many of Mr. Rose's friends told him that radio has made them read the newspaper accounts more eagerly. More critically...
...National Radio Week" was celebrated by attempts on several successive nights to exchange the programs of U. S. and European Radio Stations. For one hour, the U. S. radiocasters had the ether and the Europeans tried to keep still. For the next hour, the Europeans had the air and the Americans were supposed to do nothing but listen. The experiment was hardest on the Europeans because it was held from 3 to 5 A. M. London time, which in the U. S. are respectable hours of the previous evening. The object of choosing such inconvenient hours for the Europeans...
...were back in five seconds. They were three SSS's and three CCC's sent out by radio telegraph, racing around the World in relays. Really their time was poor-most of it being taken by the frail humans who relayed them on their way. The actual ether time for a signal to go around the World would be something less than one seventh* of a second...
