Even before the last bodies had been found, the detective story began. Federal investigators started poking through the smoldering wreckage of the DC-10 in the flame-seared field near Chicago's O'Hare Airport, collecting pieces of metal that colleagues later examined under electron microscopes. Their findings last week were enough to chill the most seasoned air traveler: the key elements that destroyed American Airlines Flight 191 and killed 274 people appeared to be a bolt 3 in. long and ⅜ in. in diameter, and a cracked metal plate. Both were parts of the pylon assembly under...
...broken bolt that searchers found beside the runway. It was one of five that held the pylon to the wing, and officials thought it had snapped because of "metal fatigue"-the progressive weakening that results from repeated stress. One investigator even christened it "the murdering bolt." But electron microscope studies showed the bolt had been broken by a sudden, violent strain. Meanwhile, a crack had been found in the plate that formed the aft bulkhead...
...storage-room spill of a quart of flammable acetone caused an hour-long evacuation of the Cambridge Electron Accelerator building yesterday morning. Officials said no one was injured in the incident, which occurred on the fourth floor of the Oxford St. research laboratory...
...twin pillars of their science. But at its heart is an almost philosophical aspect that deeply troubled Einstein. It is the uncertainty principle, which says, for example, that it is impossible to tell both the exact position and the momentum of a single atomic particle?an electron, say?because the very act of observing disturbs it. Only by statistical means (like those used to determine probability in dice or poker) can a scientist predict what the results of such an experiment will...
...supposed to bring. The U.S. agreed to let Peking open consulates in Houston and San Francisco in exchange for American consulates in Canton and Shanghai. The U.S. also promised to sell China on credit a communications satellite system that will cost about $500 million, and a 50-billion electron-volt accelerator, used in nuclear research. This would cost up to $200 million and would be the largest such installation in China, but only one-eighth the energy of one now operating at Fermi National Accelerator Laboratory in Batavia, Ill. Finally, the two countries formally agreed to exchanges of scholars, journalists...
