...center of the cloud. It was also clear that there was systematic motion inside. Just as a train whistle is higher in pitch as it approaches than when it recedes, radio waves also vary in frequency according to direction of motion. Using the radio telescope like a police-radar detector, the astronomers measured the movement within the cloud. "We didn't detect any motion in the outer, cooler regions," reports Wilking. "It was as we probed deeper and deeper that we began to see evidence of gas falling inward...
...security directive on combatting espionage. In it, he called for widespread polygraph testing to cut down on the flow of sensitive information into the hands of enemy agents and enemy journalists. The directive made all Federal employees with access to such information, including Cabinet officials, subject to random lie-detector testing. After the directive was made public, Defense Secretary Caspar W. Weinberger '38 said that taking the test "wouldn't bother me a bit." But Secretary of State Shultz would have none of it. "The day in this Government I am told that I'm not trusted...
...understand why, for instance, a man with a proven sensitivity to such matters as George Shultz sees nothing wrong with such testing. Why is being asked to submit to a urinalysis any less noxious, any less a questioning of his integrity, then being asked to take a lie-detector test...
Once an obscure gadget found mostly on the dashboards of high-performance cars or in the cabs of long-haul trucks, the portable radar detector is fast becoming standard operating equipment in workaday Chevys, Fords and Toyotas. By beeping a warning whenever a police radar transmitter is operating nearby, the small (as light as 6 oz.) electronic gizmos give lead-footed drivers a chance to slow down before a police officer can spot a speeding violation. About 1.5 million citizens bought so-called Smokey detectors last year, a 25% increase over 1984. This year industry sales are expected to keep...
...first commercial radar detector was invented in 1968 by, fittingly enough, a disgruntled motorist who felt that he had been unfairly nabbed for speeding. Dale Smith, a Dayton-area electronics whiz, dubbed his creation Fuzzbuster I. The theory behind the device is simple. Police radar sets bounce a microwave beam off an approaching car or truck in order to measure the speed at which the vehicle is moving. The target must be in a direct line of sight with the radar transmitter before an accurate reading can be taken. The radar emissions, however, can be detected by a simple electronic...
