Everyone knows that the cricket produces its chirps by rubbing one fore wing across the other. With a microscope and sound camera Entomologist Frank Eugene Lutz of the American Museum of Natural History lately discovered that a cricket, outheifetzing Heifetz, makes a full-tone slur downward from the fifth "D" above middle "C" in one-fiftieth of a second. It makes four of these notes, separated by infinitesimal pauses, at each stroke of its bow. The cricket's stridor is a love song, produced only by the adult male. When the bemused female approaches he tones down his serenade...
Earth's Curve. Exhibited to the Cleveland scientists by Charles Edward Kenneth Mees, director of research of Eastman Kodak Co., was the first photograph ever taken showing the earth's curvature. Snapped in one-fiftieth of a second from an airplane in South America by Captain Albert W. Stevens, U. S. Army photographer, the picture shows a stretch of 300 miles of pampas beyond which rise the Andes. The distant horizon line of the pampas is curved slightly downward at one end. The picture was taken on film made sensitive to red and infra-red rays (not scattered...
Snuff addicts "dip" or "sniff" four lbs. a year, apiece. Thus far in 1928, one-tenth of the population of the U. S. has consumed 41,000,000 Ibs. In 1880, one-fiftieth consumed 4,000,000 lbs. American Snuff Co. stock has slowly climbed from...
...came news. An experiment had been made with aerial photography at night by flashlight. A Martin bomber 3000 feet up dropped 50 pounds of flashlight powder which was detonated in midair. Seven special cameras and a cinema machine clicked. There was a swift and powerful flash-it lasted only one-fiftieth of a second-then a tremendous explosion "rocked the buildings," "broke windows" (a few). The photographs were a "success." "Useful in war," said observers...
...probably about as competent as the 1,500 French aviators with which France began this war. After two and three-quarters years' of this world war which has been the greatest object lesson in the value of air fighting that could well be conceived of, we have today about one-fiftieth of the number of aviators that we ought to have and that we easily might have had, if sufficient attention had been given to the matter and if sufficient money had been asked for by the army and navy...
