Freezing Frames. The effect of Goldmark's system is to free individual TV receivers from the confinement of commercial broadcasting. Under its agreement with CBS, Motorola will produce briefcase-sized player units with wires that clamp onto the antenna terminals of existing TV sets. The viewer can then choose a film cartridge, drop it into the player, and dial an unused channel. The film, which automatically threads and rewinds itself, can carry nearly an hour of black-and-white viewing and can be stopped at any time for either individual "freezes" or to flip the frames through...
Although the theory remains vague, the potential uses of Nitinol alloys seem apparent enough. Goodyear Aerospace Corp. has already demonstrated that a complex Nitinol satellite antenna crumpled up into a small ball before launching can be restored to its original form simply by heating it in space. The same procedure has been proposed for orbiting a radio telescope as large as a mile in diameter. "All we have to do," says Buehler, "is put these large structures into suitably compact packages on the ground and then kick them into space and let them unfold from solar heating...
...General Motors, Pontiac will feature a 1969 Grand Prix boasting the longest hood in the industry and superthin wires across the windshield to take the place of the traditional radio antenna that usually rises from a fender. The big Oldsmobiles are in for the biggest changes. They will remain big, but their pudgy '68 bodies will give way to more severe trim and styling...
...Entomologist Philip Callahan, of the Department of Agriculture, reports on delicate experiments with which he answered the question. Callahan caught some giant cecropia moths, which live in the woods, studied them under a binocular microscope and decided that it was tiny spikes at the base of their delicate, fernlike antennae that reacted to strong light. To check his theory, he blacked out the moths' eyes, painted each antenna black, except for the tips of the spikes, and ran minuscule wires into the main antennal nerves. Then he began subjecting them to light of varying intensity...
Their rough but unique closeup of Venus stems from 17 radar probes with NASA's 210-ft. dish antenna at Goldstone, Calif., last summer. At that time Venus was only 26 million miles from the earth. Since then, the scientists have been "drawing" a map by feeding their electronic findings into a computer. The result shows three blotches of extremely rough terrain, which Goldstein presumes are mountains, moonlike craters or fields of boulders...
