...body. His inquisitor kept coming back to the same insinuating questions about whether he had been stealing or was heavily in debt; every time he answered no, he imagined to his horror that the lines were jumping wildly. Fortunately, they were not. The young man eventually passed his lie-detector test -and thus qualified for a job as a store manager for a hamburger chain...
...become a growth industry. Restaurant chains and retail stores-both notorious targets for petty, in-house thieves-are known to be heavy users of the polygraph. Officials of Zale Corp., a Dallas-based jewelry chain, admit that they ask a large number of new employees to take lie-detector tests before they are formally hired. The Burger King and McDonald's hamburger chains also have used the polygraph on some employees, though McDonald's last month ended the practice at its California outlets under pressure from the state labor commissioner. Indeed, polygraphers figure that as many...
...past five years, to 1,200. Many operate one-machine offices, but a few companies, like Dale System Inc. of Garden City, N.Y., and Management Safeguards Inc. of Manhattan, have offices in a number of cities. Lincoln M. Zohn Inc. of Manhattan, probably the largest U.S. lie-detector firm, recorded sales of $1.5 million last year, double those of 1969, and has filed with the Securities and Exchange Commission for a public stock offering...
...Apollo 17, four wholly new instruments have been included in the ALSEP package: a mass spectrometer to measure the moon's tenuous atmosphere; a detector that will let earthbound scientists monitor the bombardment of cosmic dust particles and micrometeorites on the moon's surface; an array of four listening devices-geo-phones-that can pick up shock waves from explosive charges that will be detonated after the astronauts leave and should tell much about the substructure of the landing site; an extremely sensitive gravimeter that is designed to pick up minuscule variations in lunar surface gravity...
...years ago, University of Maryland Physicist Joseph Weber astonished his colleagues with the announcement that he had detected gravity waves. Predicted by Einstein's 1916 general theory of relativity, such waves are the vehicles presumed to transmit gravitational energy across space. Critics have contended that Weber's detectors probably sensed some of the earth's own rumblings. But if sudden variations in gravity are now simultaneously picked up by a detector on the moon and a comparable device on earth, the skeptics may well be silenced...
