...blinking lights, clicking radiation counters, and black and white checkers to signify protons and neutrons. Seaborg uses them to demonstrate the manipulation of highly radioactive substance. In one film, for example, he extemporizes while a mechanical arm juts out from a wall, picks up a flashlight and directs a beam into a vat of boiling fluid. Another arm lifts a bottle of deadly radioactive fluid and pours a tiny but lethal amount into a test tube. A third mops the floor. Some of the shows deal with historic events in the young life of nuclear physics: in one, the University...
...blaze, which occurred in Ramsey's molecular beam laboratory, started when a small welding generator overheated in "the normal course of operation." Ramsey has borrowed another generator, and expects no interruption in his work...
Fortunately for both Hollister and Fisher, they were standing directly underneath the elevator's one cross-beam, which saved them from being crushed by the debris. "We were really pretty lucky," Hollister admits...
...beam of light can be transmitted along a glass tube, why not transmit detailed images along the same path? The problem has steadily resisted the best efforts of optical researchers. But now the University of Rochester's Indian-born Dr. Narinder Singh Kapany, 30, has succeeded by applying a technique he refers to as "fiber optics." With his new method, said Dr. Kapany last week, he has already designed a glass "gastroscope" which can be snaked down the throat for a detailed closeup view of the human stomach...
...side of the planet. The radio waves from the sources are normally reflected back to the planet's surface by ionized layers in the Venusian atmosphere. The only waves that reach outer space are those that travel vertically and are therefore reflected less strongly. In effect, a broad beam of radio waves sweeps around Venus as the planet revolves. Only when the beam points toward the earth is it detected by Dr. Kraus. So the time between the peaks of energy gives Venus' period of rotation...
