...reentry, i.e., how to keep a space vehicle (or missile) from burning up due to friction when it hits the relatively dense atmosphere of the earth at 20,000 m.p.h. To study this friction in the laboratory, Dr. Gabriel M. Giannini, a close friend of the late Atomic Physicist Enrico Fermi, is building a device called a "plasma jet." A stream of inert gas such as argon is passed through a high intensity electric discharge. The resulting heat forces a jet of highly ionized gas out a small hole at enormous speed and temperature (even a small jet will quickly...
Died. Walther Wilhelm Bothe, 66, Prussian-born nuclear physicist who in 1930 produced unexpected radiation by bombarding beryllium with alpha particles, and thus led to the discovery of the neutron, in 1954 won the Nobel Prize for physics for his development and use of the "coincidence method" of measuring time with billionth-of-a-second accuracy; after long illness; in Heidelberg, West Germany...
Walt Disney, who made a mouse enter taining, last week made a mousetrap educational. To illustrate an atomic chain reaction for Our Friend the Atom on ABC's Disneyland, Disney moviemakers crowded 200 mousetraps together, each with a pair of pingpong balls poised on its taut spring. When Physicist Heinz Haber, the show's narrator, tossed a single pingpong ball into the arena of massed traps-so that each sprung trap would fire two balls to spring two more traps-the screen erupted into a chaos of snaps, pings and pongs. The mousetraps were the brightest touch...
Another Chinese physicist at Columbia, Associate Professor Chien-Shiung Wu, went to Washington. Working with a topflight team at the National Bureau of Standards, she arranged an elaborate deepfreeze apparatus to cool radioactive cobalt 60 to 0.01° above absolute zero ( - 273.1° C.). The cobalt nuclei are known to be spinning, and they continue to spin in the deepfreeze, but their random "thermal" motions are reduced almost to nothing by the extreme cold. This accomplished. Dr. Wu and her helpers applied a powerful magnetic field that pointed the cobalt nuclei in one direction as if they were tiny magnets...
...Columbia's physicists, Fridays are "Chinese lunch days," when Professor Lee, a gourmet as well as a physicist, takes a select group to a nearby Chinese restaurant, where he orders special dishes. During a very long Chinese lunch, Dr. Wu's progress in Washington was discussed excitedly. Dr. Lee turned to Associate Professor Leon M. Lederman. who works with Columbia's 385 million-volt cyclotron at Irvington, N.Y. "Why not try the mu mesons?" he asked...
