Most explanations of that phenomenon liken the sun to a dynamo. Mighty currents of electricity flowing in the solar interior generate magnetic-field lines that, like the earth's, tend to be oriented in a north-south direction. But because the sun, unlike the earth, is gaseous, it does not rotate uniformly: bands of gases around the equator circle the solar axis once every 27 days, compared with a 34-day rotation rate near the poles...
...wrapping and stretching of magnetic-field lines is also believed to be responsible for the spots' appearing progressively closer to the solar equator and the switch of magnetic polarities after each cycle. But ingenious as it seems, the dynamo model of the sun may need some serious revision. Astronomer Richard Altrock, at Sacramento Peak, has observed a brightening of the sun's corona that begins near the poles -- just when the first sunspots of a cycle break out around 35 degrees latitude -- then slowly progresses toward the equator. The brightening, he suspects, marks the beginning of still another cycle, long...
...increasingly fierce international battle for the attention of readers, filmgoers and television viewers. The New York Times proclaimed that the union would "insure Time Warner a place in the 1990s as one of a handful of global media giants." Declared the Chicago Tribune: "The deal creates a corporate dynamo." In Munich the daily newspaper Suddeutsche Zeitung disagreed, predicting that the union would be a "Tower of Babel." And on Wall Street, where there had not been much excitement since the contest for RJR Nabisco, investors and speculators were agog over the proposed $9.5 billion exchange of Time shares for Warner...
...boyish 5-ft. 9-in. dynamo with the gap-toothed grin was reared in a $9,000 tract house in the San Fernando Valley. He originally wanted to become a doctor, but show business kept catching his eye. Sally Field, a classmate at Birmingham High School in Van Nuys, remembers him standing quietly in the back of the room, watching her drama-class rehearsals...
Chandler was a rebounding dynamo. She had sevenrebounds in the first seven minutes of the game,completing the first half with 14 of Crimson's 24rebounds. As Flames Coach Francine St. Clair said,"Nobody stopped...
