...despite their losses. Next night the fighting resumed, in perhaps as weird a contact as either side has made in the war. About 8 p.m. a group of men walked through a U.S. company's command post, one of them with a flashlight in his hand. "Douse that light," snarled a U.S. sergeant major, at the same time noticing that the offender was wearing black pajamas and carrying a Chinese AK-47 gun. But the group kept right on walking, and it was several startled seconds before everybody started firing. Four of the Viet Cong were captured...
...Stanford to help the U.S. learn how to detect enemy missile launches was used by Stanford Electrical Engineer Von R. Eshleman to bounce the first radar signals off the sun.* Classified research at Michigan helped Emmett N. Leith develop the new science of holography (see SCIENCE), which uses laser light to produce three-dimensional images with potential uses in art, television and industry. Says Leith: "The idea that you can close yourself off to these programs is pure ignorance...
...other in a complex sound pattern that is, in effect, an acoustical "picture" of the object being scanned. The mixed pattern of sound is transmitted as electrical en rgy from the microphones to an oscilloscope-similar to a television picture tube. The oscilloscope then converts the electrical energy into light patterns. A special polaroid camera records a time exposure negative of the converted sound pattern...
Rapid Read-Out. From this point on, Metherell's technique closely parallels that of optical holography (TIME, March 18, 1966). The filmed pattern is illuminated from one side by light from a helium-neon laser device. The light is diffracted by the converted sound pattern into an image of the original object. Viewers standing on the opposite side of the film can then see a measurable, three-dimensional representation of the object that has been scanned. By reconstructing three such photographs taken with sounds of different frequencies, the scientists believe that they wil soon be able to make multicolored...
...Dogs & Bowling. Inside, only the entertainment had changed. Under the same frescoed ceiling with its soaring tiers of light-studded arches, the New York City Ballet performed A Midsummer Night's Dream. "Why don't they build like this today?" said Ballet Director George Balanchine. "Nothing could be more modern than this...
