...moon-probe Pioneer is man's first triumph in applied celestial mechanics. Earth satellites, like bullets, baseballs or missiles, need to contend with the earth's gravitation only. Pioneer was born on a higher level of technical evolution. Its projected course toward the moon took into account three of the overlapping gravitational fields (the earth's, the sun's, the moon's) that govern the solar system. To set it on its trajectory called on theoretical astronomical and mathematical lore that man has painstakingly been accumulating without practical employment since the birth of science...
...sums as quickly as he can raise a telephone. Says Playwright Marc (Green Pastures) Connelly: "Stevens is a stage-struck shrewdie who brings nothing to the theater but a knowledge of real estate. The only thing you can say for him is that he keeps employment at a high level...
...some alarmists, is ruining the nation's health by eliminating the normal healthy exercise of walking. Appropriately, Directors Alfred P. Sloan Jr., 83, and Charles F. Kettering, 82, of General Motors, both proudly proclaim that they have never taken a lick of exercise in their lives. On level ground, the farthest they walk is from office or apartment door to car or from car to plane. Up and down, "Boss"' Kettering gets a fair amount of walking because he is too impatient to wait for elevators, walks up two floors and down three in offices and labs...
...automobile tire or piston wears out, so eventually must human organs, is only half true. In the youthful, still growing organism, cells divide rapidly, and all the components of the body (except nerve cells) are not only quickly added to, but also constantly replaced at the most intimate molecular level. This process does not stop with maturity; it goes on until death. But there is evidence that the rate of cell and tissue replacement slows down, until- perhaps at different times in dif ferent tissues - it is markedly less than the rate of natural death and destruction...
Bismarck's Diktat. Until that day comes, society as a whole and millions of individuals and their families will be faced with problems of aging at a grosser, more practical level. The trouble may begin at 65, when (thanks to a chance decision by Bismarck in the 1880s) most pension plans and many compulsory retirement plans begin to operate. For business, this cutoff point may be sound up to a point. Says G.M.'s Sloan, who kept administrative control until he was 71: "The rule is probably sound, because, while some men can stay in administrative posts beyond...
