Explains Dance Director Rulon Stanfield, a Utah business engineer: "The glory which one attains in the next world is relative to the amount of his service to his fellow man on earth. And no matter how many dollars you sacrifice, you forget all about it when you see those young dancing feet...
...last to his own destruction. The curtain rises on the interior of a spaceship dominated by the towering electronic brain, a mechanism so advanced that it is nearly human. Ranged in front of it as ghostlike silhouettes, the passengers chant a lament for the planet Doris (actually the Earth) they just left behind...
Storm Trouble. The most sensitive way to detect distant earthquakes-or underground atomic explosions-is by measuring the long waves that travel along the earth's surface instead of striking deep into its interior. Drawback to this method is that even such minor disturbances as a storm at sea set up shorter surface waves (microseisms) that obscure or blot out the record. The Lamont improvement is an ingenious filtering device that separates earthquake waves from local confusion...
...system is based on a type of seismograph in which a heavy weight is suspended so that it holds still while the earth waves move past it. The slight motion between the weight and electrical elements close to it creates a fluctuating electrical current. Before the current reaches the recording apparatus Pomeroy and Sutton pass it through a special galvanometer-a coil that makes a small weight move against the resistance of a delicate spring. The waves in which they are interested are long and of low frequency (40 to 50 sec.). They found that by choosing a galvanometer with...
Pomeroy and Sutton are guarded about the effect their filters will have on international networks for detecting underground nuclear tests. They calculate that six stations equipped with the new instruments could detect most underground disturbances anywhere on earth that have the energy of a "nominal" (20-kiloton) nuclear bomb. Between 20 and 50 stations (v. the presently postulated 180) would be required not only to detect but also locate such disturbances. They are not prepared to estimate just how many more would be required to detect explosions of bombs as small as 5 kilotons or how accurately they could distinguish...
