...human eye has ever seen a breeze. But two physicists recently produced a photograph of one. They announced a high-speed photography technique by which they have made unusually sensitive pictures of air currents, heat waves, sound waves...
...passes through air masses of varying density. Barnes and Bellinger caught these rapid changes in air density by means of an extremely fast mercury lamp with an exposure of less than one-millionth of a second. The light, flashed through a region of disturbed air, recorded on a photographic plate a "shadowgraph" showing groups of bunched air molecules. Using a more elaborate rig, which has a knife-edge that stops all but the bent light rays, the experimenters developed a technique so sensitive that it can photograph the heat rising from a human hand at room temperature...
Dziepatowski was 21 or 22. Through other members of the underground he got Karski false papers. Karski was now Kucharski, born in Luki, in poor health, a primary-school teacher. He was sent to a photographer in a poor district, given a photograph that was enough like him to be claimed as his, but vague enough to be disowned if necessary. For two weeks Karski waited, memorizing the new story of his life...
...feature of the exhibit is the "Vectograph," a three-dimensional picture taken from the air, which, viewed with the naked eye, seems to be a blurred photograph, but which appears as a revealing photograph in three dimensional detail, when seen through a special polaroid viewer. Supplementing the 16-poster display is a set of pictures describing the officers' programs in the Yard...
Glimpses of the Moon. Last week Britain's famed jack-of-all-sciences, J. B. S. Haldane, philosophically predicted a big postwar future for V2, which he thought could rise to 200 miles if fired vertically. Mused Haldane: "it could take photographs . . . [of] the sun and perhaps other heavenly bodies. . . . For the cost of a day of war, it should be practicable to send a series of rockets round the moon and photograph its far side...
