...early riser (6:45 in winter, 5:30 in summer), Dr. Keys eats a leisurely breakfast-half a grapefruit, dry cereal with skim milk, unbuttered toast, jam and coffee. Then, brown paper lunch bag on the seat beside him, he drives to work in a two-toned Karmann-Ghia. Although lunch is slim-a sardine sandwich, an olive, a cooky and a glass of skim milk-Keys eats with deliberate slowness. "I don't like to insult food," he says. Lunch done, he sits back, closes his eyes, and goes to sleep for exactly ten minutes in his office...
...knew it. Gone were the cigars and bourbon and branch water ("striking a blow for liberty") that he gave up just before his 90th birthday. He is still quick to provide visitors with the wherewithal to strike their own blows, but his current personal quaff is just plain grapefruit juice...
...size or mass of his latest white dwarf, but he believes that it weighs at least ten tons, or 20,000 lbs., per cubic inch. It could conceivably weigh as much as 1,000 tons per cubic inch, in which case a chunk of star no bigger than a grapefruit would weigh more than the 84,000-ton Queen Elizabeth...
When Vanguard I, the U.S.'s second satellite, popped into orbit early in 1958, Nikita Khrushchev derided it as a "grapefruit." It was indeed small (6.4 in. in diameter, 3.25 Ibs.). But last week, as it completed its second year in orbit, Vanguard had proved to have two virtues that the massive Soviet satellites lack. First, it soared into so high an orbit (apogee 2,500 miles above the earth, perigee 400 miles) that the outermost fringes of the atmosphere exert almost no slowing effect on its motion. It has kept going while heavier competitors sagged into the atmosphere...
Vanguard's second virtue is the solar battery that has kept its small radio beeping steadily, long after bigger satellites lost their voices. Tracked by its radio signals, the "grapefruit's" motions in its orbit have given invaluable information about the earth's slightly bumpy gravitational field, and about the shape of the earth itself. Last week another bit of information came down from the little satellite. There was a slight, unexplained wandering in its long-studied orbit. After much calculation, Dr. Peter Munsen and other orbit experts of the National Aeronautics and Space Administration reached their...
