...bombarded by radiation from the stars, they respond in a precise and predictable way: they radiate electromagnetic waves at characteristic frequencies. Detected by radio telescopes, these waves are the "fingerprints" that scientists use to identify interstellar molecules. Carbon-monoxide molecules, for example, radiate at an incredible 115 billion hertz (115 billion cycles...
Doubts Dispelled. Until recently, radio telescopes were not designed to pick up such high frequencies, but the Bell researchers-Arno Penzias, Robert Wilson and Keith Jefferts-had some timely aid: a newly developed telephone transmission device that can convert frequencies in the multibillion-hertz range into more easily detectable radio frequencies of about 100 million hertz. After adapting this device to the National Radio Astronomy Observatory's 36-ft. dish antenna at Arizona's Kitt Peak, the Bell scientists aimed the radio telescope at the distant Orion Nebula, a region of glowing gases more than 1,600 light...
...many, the trip was an initiation into the politics of protest. "This is the first time I've ever done anything," said Seymour Hertz, 37, a specialist in corporate and securities law. "I'm just frightened by what's happening in this country; Viet Nam isn't worth it." Most regarded the visit to Washington as a unique opportunity to get their ideas on the war across to the Government. "We're lawyers, not longhairs," said Randy Bevis, 29, a member of Thomas Dewey's law firm. "We're respectable, and I think...
...folksy headline: "Honest, Jim and Maureen Cunningham, now you can afford to go to Britain." A year ago some ads for Eastern Air Lines were entirely given over to touting the smiles of the stewardesses; today Eastern's ads carefully specify price, service and routes. In 1969 Hertz highlighted its costlier car rentals...
