...buildings. U.S. building codes are written to save lives, not prevent all damage. Modern structures are designed to sway and maybe even crack in a quake, but not to break apart and crush their inhabitants under falling debris. Says Bill Iwan, director of the earthquake engineering research laboratory at Caltech: ``With buildings, if you walk out after a quake, the designers did their...
Stone said that by teaching, he feels as if heis giving something back to the remarkableinstructors he had as an undergraduate in chemicalengineering at the University of California Davis,and as a graduate student at Caltech...
...good news, say scientists, is that last week's tremors had only a mild impact on the San Andreas itself. The bad news is that they increased subterranean stresses closer by. Caltech geologist Kerry Sieh, for one, is worried that the violent release of energy may have adversely affected the Elysian Park system, a deeply buried network of thrust faults directly under Los Angeles. Parts of this system have lain dormant, Sieh says, "since before Abraham." But he cannot predict when the faults might awaken...
Harvard's "citation impact" rate compares with an international average of just more than two-and-a-half citations per paper. Second in the survey was the National Institute of Standards and Technology (8.94 citations per paper), followed by Caltech (8.30 citations per paper) in third place...
...Earth, and its daytime temperatures can reach 430 degreesC (800 degreesF). The last thing scientists expected to find there was ice. But that is just what a new radar study of Mercury, reported in Science, has detected. Planetary scientists at NASA's Jet Propulsion Lab and at Caltech aimed powerful radar beams at both of the planet's poles; the return signals bore the telltale signs of having bounced off a frozen surface. Like Earth and Mars, Mercury appears to have polar ice caps...
