Lanzmann, at times, is incredibly subtle. Without condescension or harassment, usually patient, he is always on just the right wavelength for the individual conversation. The results can be endearing, terrifying and just astonishing...
...financial advisers abscond with all her cash. One of those assets, she discovers, is a detective agency run by David Addison, a TV- obsessed private eye with boundless self-confidence but few clients. She tries to help him drum up business, but they are rarely on the same wavelength. "This is always how I imagined it would be with a partner," he enthuses. "Two people working shoulder to shoulder, seeing eye to eye . . ." "Eating hand to mouth," she ripostes...
LASERS. They are devices that generate high-powered, concentrated beams of light, almost perfectly parallel and of a single wavelength. The light from a lamp, in contrast, is a fuzzy discharge wiggling at different wavelengths and scattering in every direction. Laser beams travel at the speed of light (not surprising: they are light, though not always visible) and can be focused over thousands of miles of space to burn a hole in the skin of a Soviet missile, destroying its guidance mechanism and deactivating its warheads...
...reaction of gases such as hydrogen and fluorine, are the most powerful lasers now in use. But a missile-killing laser beam might have to be 10 million times as powerful as the one that the Air Force is now using in antisatellite weapons tests. Also, because its long wavelength somewhat spreads out its focus, a chemical laser beam might have to be held on precisely the same spot on a missile's skin for as long as seven seconds; during that time the missile might rise 20 miles. Because a ground- based laser could not send a beam around...
Cornell said the telescope is the center's response to a national need in astronomy to advance the study of unexplored regions and stellar occurrences using "sub-millimeter waves"--radiation with a wavelength of less than a millimeter. "This is the spearhead of a national drive in astrophysics to advance study in this area," he said...
