...ways of teaching science, math, reading and foreign languages will reach more youngsters than ever. From noon seminars to Saturday morning classes, more time will be spent at studies. TV teaching will reach nearly half the classrooms in California. In six Midwest states, two DC-6 airplanes will beam taped lessons to earthbound schools under the Ford Foundation-financed Midwest Program on Airborne Television Instruction, which by June may reach 2,000,000 students...
Russia's most useful eavesdropping weapon is a tiny, kopeck-sized reflector. It was such a reflector, installed inside a plaque of the U.S. Great Seal in the Moscow embassy, that U.N. Ambassador Henry Cabot Lodge displayed to the Security Council last year. When an infra-red beam is aimed at the reflector from outdoors, it acts as a microphone. Alternatively, but less reliably, the infra-red beam can be trained on any imperceptibly oscillating object, such as a metal lampshade or empty highball glass, that can act as a crude reflector for conversation...
...long been the practice of wealthy U.S. museums and collectors to buy historic European buildings, then transport them beam and brick across the Atlantic. Last week the process was somewhat reversed; in Great Britain an American museum was open near the Regency resort town of Bath. Its purpose: to show the British just how their cousins lived from the landing of the Mayflower to the beginning of the present century...
Dives & Loops. To learn more about the moth's methods of escape, the two scientists set up a floodlight and trained a camera on its beam. When an insect flew across the floodlit area, the operators opened the camera's shutter and turned on their electronic beeper to simulate a cruising bat. "Many insects." say Roeder and Treat, "showed no change in flight pattern when they encountered the sound. In others, the changes in flight path were dramatic in their abruptness and bewildering in their variety. One of the commonest reactions was a sharp power dive into...
...team (Albert Ghiorso, Torbjorn Sikkeland, Almon E. Larsh and Robert M. Latimer), by coating thin nickel foil with a circular film of artificial californium (element 98) only one-tenth of an inch in diameter. Placed in a container filled with helium gas, this tiny target was bombarded by a beam of boron nuclei from the lab's heavy-ion linear accelerator. Most of the boron bullets missed, but a few scored a bull's-eye on californium nuclei. Atoms formed by the combination of californium and boron bounced off the nickel foil, were slowed by collision with helium...
