...peculiar language of the document was easily skirted by the Germans, who used poison gas to devastating effect in World War I. In April 1915, German soldiers surreptitiously installed 5,730 cylinders of liquid chlorine in the trenches along a four-mile section of no-man's-land near the Belgian town of Ypres. Using a heavy artillery barrage, the Germans were able to shatter the cylinders and release the lethal gas. In a single afternoon, 5,000 French troops were killed and an additional 10,000 were injured. The carnage in Flanders was commemorated in a poem by Wilfred...
...vitesse), hits only 186 m.p.h. One maglev is already running: a short, slow-moving (25 m.p.h.) line in Britain that shuttles people from Birmingham's airport to the railway station. But much faster prototypes are being tested, and ambitious projects could get under way next year, including a 230-mile link between the Los Angeles area and the gambling mecca of Las Vegas...
...they achieve perfect conductivity. Turning the thermostat that low requires costly liquid helium and heavy compressors aboard the train to reliquefy the evaporating helium. The Japanese, who have poured $379 million of private and government funds into the maglev, have reached a speed of 323 m.p.h. on a 4.4- mile straight track at Miyazaki on the southern island of Kyushu. But the track has none of the loops and sharp curves found along real railways. It will probably be at least five years before the Japanese develop a model that is both economic and practical enough to be commercially viable...
...have to be serene to carry the Japanese through what looks to be years of headlines and television coverage for the West Germans. Their Transrapid program, which has consumed more than $830 million of public funds, is readying its final prototype, the TR-07, for tests on a 20-mile track with loops at both ends at Lathen, near the Dutch border. A previous model, the TR-06, has already run the straightaway at 256 m.p.h.; the TR-07 is designed to reach 300 m.p.h. Most impressive of all, though, is the Transrapid consortium's push to break ground...
...physicists reached their conclusion as the result of an experiment conducted in Greenland last summer. They lowered a supersensitive gravity meter into a mile-deep hole bored in glacial ice -- chosen because its density is more uniform than that of rock -- and monitored the gravitational pull as the meter descended. What occurred was startling: the expected increase in gravitational force predicted by Newton was there, but it got stronger faster than expected. Either something was enhancing the force of gravity or the researchers had come upon a heretofore unknown, far more complex working of gravity itself. Or, just possibly, they...
