...Alarm Clock. When Hunt and crew had a rat sleeping peacefully, they recorded its heartbeats on an electrocardiograph (300-350 beats per min.). Then they squirted it with a beam of silent, invisible, 250,000-volt X rays. In about 12 sec., the rat woke up, sometimes going into a violent "state of alarm." Its heartbeat would speed up too. But if the radiation continued for long, the rat would go to sleep again, like a human grown accustomed to a steady night-time sound...
Broad Goal. The solution is to put the state's best teachers on TV and beam their skills at every classroom. First talked up by a group of businessmen, notably Textile Manufacturer John Cauthen, closed-circuit TV can eventually cover the state at a yearly cost of only $14 per pupil. The goal is still distant, but the state legislature has yet to turn down a single new TV appropriation. Each year more coaxial cables are run from schools to microwave stations that pick up broadcasts from the South Carolina Educational Television Commission's well-appointed studios...
Since laser light can be concentrated into a thin beam that barely spreads out at all, Professor Louis Smullin and Dr. Giorgio Fiocco, the M.I.T. engineers who performed the experiment, estimate that the laser's light diverged only about two-thirds of an inch for each mile of its quarter-million-mile journey to the moon. When it reached the moon's mountains, the laser beam lighted faintly a circular area only two miles in diameter...
...speed of light is measured by reflecting a beam back and forth between carefully placed mirrors and clocking the time it takes the light to cover that measured distance. Dr. Lowther proposes to improve this experiment by using the pure brilliance of newly developed lasers (TIME, April 20) and new electronic techniques. He hopes to pinpoint the speed of light to three parts per 100 million, which will give the distance to the moon within...
Starting quickly the Crimson first stringers piled up a 5-0 first period lead. The attacking trio of Lon Williams, Grady Watts, and Woody Spruance, so effectively sniffed by Princeton Saturday, was back on the beam...
