...Andreas is well understood--the fault marks the major interface between two sections of the earth's crust that are grinding past each other--scientists argue endlessly about the details. Among the most pressing questions are whether the rock in the fault zone is intrinsically strong or weak and whether an increase in fluid pressure helps trigger earthquakes by prying apart the fault. "We have lots of ideas, and finally we're getting a chance to test them," says William Ellsworth, chief scientist for the USGS Earthquake Hazards Team...
WHEN WILL WE GET OSAMA BIN LADEN? That is a question that goes far deeper than you know. In the chain that you need to successfully wrap up the war on terror, we have some weak links. And I find that until we strengthen all the links, we're probably not going to be able to bring Mr. bin Laden to justice. We are making very good progress on it. But when you go to the very difficult question of dealing with sanctuaries in sovereign states, you're dealing with a problem of our sense of international obligation, fair play...
...Fischbach is proved right, his hypothetical force, which he calls hypercharge, would be the fifth known basic force. (Four forces are known to exist: gravity; electromagnetism; the strong force, which binds the atomic nucleus; and the weak force, which is responsible for certain types of radioactivity.) Hypercharge, Fischbach reports in Physical Review Letters, is an extremely weak repulsive force that acts between objects no more than about 600 feet apart and varies in strength from element to element. It is strongest in iron and weakest in hydrogen. Thus, the physicists contend, if an iron ball and, say, a feather were...
Cautious forecasters point out, however, that the boom machine still has a few weak spots. The oil bust, for example, has threatened the stability of energy firms and banks in the Southwest. "There are always things that can go wrong," concedes Beryl Sprinkel, chairman of President Reagan's Council of Economic Advisers. "But I'd say they are minimal at the present time, and the things that can go right are pretty evident...
Inflation seems so weak that many businessmen and economists think the Federal Reserve could allow interest rates to fall even further without risking a jump in prices. Says Edward Yardeni, chief economist for Prudential-Bache Securities: "Lower rates could deliver us into the golden land of zero inflation and 6% economic growth. So why not ease...
