...influences of the home environment on delinquency operate selectively to propel toward maladjustment only those children characterized by specific traits which enhance their vulnerability. Some such traits are essentially constitutional and therefore rigid. For these, it is possible to reduce the hazards of delinquency by altering environmental factors. Other traits are essentially due to sociocultural conditioning and are therefore more plastic and modifiable...
...well-knit, Uelses runs the 100-yd. dash in 9.7 sec., needs only an abbreviated, 104-ft. approach (standard: 130-140 ft.) to reach top speed. He gets so much lift that he needs only a cut-down, 14-ft. 11-in. pole to propel his body across a 16-ft.-high bar. Aloft he is unusually graceful, clearing the crossbar with his feet tucked closely together, stomach sucked in, arms flung high over his head. Uelses never rests between vaults. He paces back and forth, stares up at the crossbar, tidies up the runway with a broom. "Mental attitude...
Purcell's views, which were given national attention over the weekend in a New York Times article on the possibility of communication with other worlds, are based on elementary mechanical considerations which show that preposterous amounts of fuel would be required to propel a rocket to another planetary system and back to the earth within a reasonable period of time...
...engine developed by the family chauffeur. By pressing tirelessly for mechanical perfection of the diesel engine and touting its economy, Miller transmuted this white elephant into a golden goose. Though Cummins' sales declined slightly to $64 million in 1961's first half, the new engines should soon propel the company's earnings to record highs...
...book rise above the level of applied science. About the only novel idea is highways with cables carrying high-frequency current under their pavement. The electric field surrounding the cable, says Engineer U. A. Dolmatovsky, will hold automobiles out of contact with the ground and at the same time propel them forward at 150 m.p.h. There will be no accidents no matter how heavy the traffic, because automatically guided cars are free of human error. Such high-speed cars will operate only on main highways. Inside cities says Dolmatovsky, the citizens will use slower, driverless taxis, which will be plentiful...
