Cavalier as he may have been about his wives, he had a deep moral sense. At the height of World War I, he risked the Kaiser's wrath by signing an antiwar petition, one of only four scientists in Germany to do so. Yet, paradoxically, he helped develop a gyrocompass for U-boats. During the troubled 1920s, when Jews were being singled out by Hitler's rising Nazi Party as the cause of Germany's defeat and economic woes, Einstein and his "Jewish physics" were a favorite target. Nazis, however, weren't his only foes. For Stalinists, relativity represented rampant...
...navigation gear had failed: after all, it had certainly been working well enough to guide the vessel up the channel in the first place. Declared General Lennart Ljung, the Supreme Commander of the Swedish Armed Forces: "I don't think it happened because the gyrocompass broke down. They have many other ways of navigating...
...mission was canceled when three of the eight helicopters heading toward Desert One broke down while flying through a blinding sandstorm. An electrical power supply on one craft overheated and failed, knocking out the gyrocompass, the horizon indicator and the cockpit lights. The crew flew back to the Nimitz, making a dangerous landing, with fuel tanks nearly empty...
...fail to meet adequate safety standards. The Argo Merchant, for example, was involved in 18 "incidents"?including two previous groundings?before the Nantucket disaster. Her captain since June, Georgios Papadopoulos, 43, admitted at a hearing last week that his ship carried no LORAN (long-range navigation) equipment. His gyrocompass, he said, was not being used just prior to the accident because it was six degrees off, and the helmsman was steering by magnetic compass. He himself had not had an accurate fix on his position for more than 15 hours. Even if he had known his position, he might...
...detection systems that have been used by submarines and sub detectors since World War II, and the more advanced electronic navigation devices that have recently come into use aboard high-speed aircraft. Mounted beneath the Alan's hull are four small pairs of sound projectors and receivers. A gyrocompass keeps them constantly aimed toward the cardinal points of the compass as powerful beams of sound are caromed off the ocean floor and picked up again...
