...wide variety of jobs requires a wide variety of electronics. The surface of the 170-lb. sphere glitters with electricity-generating solar cells. Suspended by nylon cords inside, a 20-in. aluminum canister is crammed with gadgetry. Pink plastic foam nestles around batteries, switches, sensing instruments, 1,064 transistors and 1,464 diodes. But for all the jobs that it can do, Telstar's most spectacular achievement is its radio and TV relay system. A receiver inside the canister amplifies signals received from earth 10 billion times, changes them in frequency from 6,390 to 4,170 megacycles...
...surface. This vertical distance can be measured accurately; if it is too great, the waves almost surely will not have come from a test. It is not likely, say the seismologists dryly, that even the most industrious Communists will explode secret tests far down in the hot, semi-plastic depths of the earth...
...Poupees de Paris, is modeled after the revues at Paris' Lido and Folies Bergere, and it is the smash hit of the Seattle World's Fair. Costing $200,000 to produce, it is a spectacle bathed in dancing waters, fireworks and rain. The puppets-131 rubber and plastic females, seven wooden males-are about three feet high, and no expense has been spared in fitting them out; some of the miniature gowns cost as much as $2,000 apiece and were designed by Balmain. Star puppets resembling such people as Mae West, Charles Boyer, and Liberace speak with...
...cheaper process developed by Chemistry Professor Harry P. Gregor of Polytechnic Institute of Brooklyn uses thin plastic membranes containing submicroscopic pores that permit the passage of small atoms with positive electric charges. Milk is made to flow along one side of a membrane; on the other side is a solution of such salts as calcium and sodium chlorides that are naturally present in milk. If the milk contains strontium 90 atoms, they pick up positive electric charges from a current flowing through the solution. Then they slip through the membrane and lose themselves in the harmless salts. Dr. Gregor thinks...
...Into a plastic tank the budding ichthyologist pours tepid tap water. Into the tap water he drops tiny fish eggs. Twenty minutes to two days later, pop! pop! pop! -instant fish, tastefully colored red, yellow, blue. They are an African variety, the eggs of which survive even when dried out during droughts, and hatch when the rains come. What do they eat? Instant shrimp, of course. Into a separate small tank in the aquarium goes salt water, and into the salt water goes a powder that turns into hundreds of tiny shrimps (a magnifying glass is included). By the time...
