...analyze them. Science's heavy artillery comes in two different forms. One is the linear accelerator, which shoots the particles down a long, straight tube. The largest of these is the two-mile-long machine at Stanford University, which recently had its power increased to 22 billion electron volts.* The other, more common form is the circular accelerator, which whips particles round a ring-shaped tunnel to get them up to speed. With the monster at Batavia not yet in operation, the world's most powerful atom smasher is the Soviets' 76 billion-electron-volt accelerator near...
Amid the crack of 450-volt xenon strobes, the silent zap of lasers and an unprecedented clicking of turnstiles, the Los Angeles County Museum's exhibition called "Art and Technology" is under way at last. It will run through August, and it affords a revealing spectacle of the stimuli and problems that rise out of a major encounter of art and industry...
...quite. After Shepard and Mitchell made the usual in-flight inspection of the lunar lander, an unexpected voltage drop was discovered in one of the two batteries of Antares' ascent stage, which would take the astronauts off the moon. The reading was only three-tenths of a volt lower than normal; yet mission controllers felt that it might be a sign of more serious trouble-a leakage in the LM's critical electrical circuitry, for example. That too could have barred a moon landing. Happily, a subsequent check by Mitchell, who holds a doctorate in astronautics from M.I.T...
Unable to empty out the tank during tests at the Cape, NASA technicians applied 65 volts to the heater, trying to boil off the semiliquid oxygen. The voltage fused the inadequate 28-volt cutoff switches, allowing the temperature in the tank to rise to 1000° F. and damaging the Teflon insulation on the wires. This led to the arcing that occurred during the mission. Why did the Cape Kennedy technicians have to resort to this untried procedure for emptying the tank? Because, said the panel, the tiny tube through which oxygen is fed in and extracted had probably been...
