...President's coolly proper speech of greeting. "The Soviet people want to live in friendship with the American people." But Nikita Sergeevich Khrushchev was not five minutes into his speech or 15 minutes into the U.S. before he sounded a prideful note of power that was to echo, sometimes blaring, sometimes muted, as the dominant theme of his trip. "Shortly before this meeting with you, Mr. President," he said, "the Soviet scientists, technicians, engineers and workers filled our hearts with joy by launching a rocket to the moon. We have no doubt that the excellent scientists, engineers and workers...
...idea came to him, he says, during a hurricane-tossed Atlantic crossing. "Sitting in my cabin, I suddenly realized that in a storm you stop noticing the noise; as it stays at a high level, your hearing threshold falls. I tried out the Lear speech and heard it echo sharp and clear in my mind. That's the way it should be. The storm's inside Lear...
...along high school corridors in 1959. Dobie starts out safely enough, tells what "bugs" him, what's "a gasser," who's "kooky" and "all that jazz." But in no time at all, the gassers have become "marvy," the jazz is "jive," and people start "yacking away." An echo from the past informs everyone to "stay loose." Another, from the Dark Ages, adds...
...range detection system. Since both the ionosphere and the surface of the earth will deflect radio signals, a transmitter can angle its beam upward and the broad waves will carom back and forth between ground and sky as they proceed to circle the earth. Each deflection sends back an echo to the home transmitter, and this "back-scattering" was the phenomenon that attracted Thaler...
...wouldn't the globe-girdling radio waves also bounce off the trail of ionized gases left by a high-altitude rocket or the cloud of ionized gases created by a nuclear explosion? Then, if there were even a slight difference in the returning echo patterns-and if receivers could be made sensitive enough to detect the difference -monitoring oscilloscopes could display telltale evidence of what the waves had encountered on their travels. Since these radio waves bounce around the earth, the new method would overcome the limitation of radar, whose line-of-sight waves travel in straight lines, thus...
