Ingenious are the methods of the monitoring crews. Often they trace an illegal transmitter to a large office building. They find out which office houses the set by using portable detector outfits, small enough to fit into a vest pocket and equipped with indicators geared to rise with proximity to the transmitter. Most such bootleg equipment is used by gamblers, who are often able, by means of quick flashes, to place last-minute bets on horse races already...
...MOONLIGHT-Helen McCloy - Morrow ($2). Fairly cerebral story of murder at Yorkville University, where Victim Dr. Konradi, an Austrian, had found refuge and money for biochemical research. When suspects refuse a lie-detector test, a psychiatric assistant to the D. A. does his stuff...
...metres. Naturally the energy of each wave is tiny and each atom sends out a wave only once in 1,000 to 100,000,000 years. But there are so many billions of atoms in a small pinch of substance that Dr. Rabi gets a continuous program on his detector, which is a ribbon of incandescent tungsten in an oscillating electromagnetic field. He expects to use atomic radio to learn more about the nuclear structure and energy mechanism of atoms. The physicists admired his discovery and Dr. Rabi got a $1,000 prize for the A. A. A. S. convention...
...listener to hear it louder in one ear than in the other. He rotates the bar until the sound volume is equal in both ears; then the bar is perpendicular to the direction of the sound source. In antisubmarine practice, it was soon found impracticable to rotate the detector, whether attached to the hull of the patrol ship or towed behind. So the detector was kept stationary and the effect of rotation was obtained by lengthening the path from one receiver to one ear, shortening the other, until the sound volume was equal in both ears. This was called "binaural...
...parent and educator suspects that children's radio programs overexcite their youthful audiences. Parent John James DeBoer, whose one child is too young to listen to radio, investigated the suspicion. He questioned 738 grammar-school children, had 486 radio-listening moppets watched, used a "photopolygraph" (modified lie detector) on 148 to measure respiration, blood pressure, pulse, electrical resistance of skin...
