...Rainier underground explosion to serve as an example. The only observable products of an underground explosion are shock waves, waves which are very similar to those of an earthquake. The experts concluded that a control system of 180 stations equipped with seismographs would be adequate to detect with "good probability" explosions of five kilotons or more. Such a system could also spot tests of smaller extent but with less reliability...
...same witness chair had been occupied for four days by a tawdry succession of fixers and schlockmeisters, corrupters and corrupted (see above). Bob Kintner had gone to Washington with the difficult task of showing that 1) NBC had done everything that could be reasonably expected to prevent or detect fraud on the quiz shows, and 2) the quiz scandals did not reflect a sickness in other areas of television. In 3½ hours of testimony, Kintner notably failed to prove either point...
...chemistry went to Professor Jaroslav Heyrovsky, 68, of Charles University, Prague, the first Czechoslovak to win a Nobel Prize. The award came as much-belated recognition for his discovery of polarography, a delicate electrical method of chemical analysis. It works by measuring the properties of ions, and can detect slight traces of metals in a drop or two of a complex solution. Discovered in 1925, polarography is still used all over the world by analytical chemists...
Faithful to this rigid ritual, few writers busy paying for their swimming pools and Thunderbirds with Private Eye cash could take the facetious oath of Britain's Detection Club-that their heroes "shall well and truly detect the crimes presented to them . . . not placing reliance on nor making use of Divine Revelation, Feminine Intuition, Mumbo-Jumbo, Jiggery-Pokery, Coincidence...
...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 cannot see beneath the horizon...
