...Polar lee. Debus let his gaze linger on the mighty Saturn V rocket beneath the Apollo 17 spaceship. "The Saturn V is the end too," said Debus. "I don't believe we will build a stronger rocket in this century. The Saturn can boost a payload of 200,000 lbs. into orbit. If you want more payload than that, it is cheaper to launch several Saturns than to develop a new rocket...
Such symbolism aside, the motives and methods of chess players are as varied as their personalities. Even among the small number of men who have been world champions in this century there have been polar differences. Emanuel Lasker, title holder from 1894 to 1921, was a philosopher, mathematician and thoroughgoing "square" by most psychological standards. His satisfactions from chess appear to have been entirely intellectual. Cuba's Jose Capablanca (champion from 1921 to 1927), who gave up the orderliness of a projected career in engineering to become a chess giant and his country's hero, enjoyed competition...
Fired to an altitude of 492 nautical miles, the satellite is expected to operate for a year in a near-polar orbit that runs almost parallel to the earth's axis of rotation. Sweeping down from high above the Arctic Circle to Antarctica, it will then head back north every 103 minutes. This orbit has an important advantage: it will bring the spacecraft back over the same spot on earth every 18 days at almost exactly the same time of day. Thus, ERTS's photographs, each covering a 100-by-100-mile square, will be taken at each...
...planet last November. By patiently matching and assembling these photographs, scientists at Caltech's Jet Propulsion Laboratory have put together a jigsaw-puzzle-like map of a strip of Mars extending 30° above and below the equator as well as an overall view of its south polar cap. Indeed, detailed photographs, showing features as small as 100 yards across, were among the highlights of the 15th annual session of the international Committee on Space Research, attended by more than 1,000 scientists from 35 countries...
...into the rhythm of the sermon, everyone had to reach out and possess each maxim as if it were a truth of infinite wisdom that had never been expressed before. An organic interchange of energy and enlightenment flamed up with every sentence, accelerating until all strength was spent. The polar opposite of a Harvard lecture...
