Rockford (pop. 140,000) was the victim not of a lethal twister but of glitches in new computer software used by the National Weather Service. The tornado alert was one of five test alarms that were incorrectly sent out to local radio stations last week. Few Rockford residents believed the warning anyway. They know their weather, and early-morning tornadoes are rare indeed. Says Rockford Mayor John McNamara: "We don't take tornadoes lightly here...
...first speech was delivered at a session on strategic arms reductions, the second at a session on antiballistic-missile (ABM) defense and the Strategic Defense Initiative, the third at a session on the problem of banning underground tests ((a so-called comprehensive test ban, or CTB)). I attach special significance to the second of the talks, in which I came out against the "package" approach, whereby the U.S.S.R. is strictly linking agreements on nuclear weapons reductions to conclusion of an SDI agreement. Another important statement was on the safety of nuclear power, in my third speech. I would like there...
...principle divide every nuclear charge into four relatively independent systems: electronic, ballistic, atomic and (for a hydrogen device) thermonuclear. The reliability of the first three systems can be confirmed by laboratory tests supplemented by experiments in which a low-yield fission or fusion reaction releases a small quantity of neutrons, which can be measured by a counter close to the charge to be tested. The fourth system -- thermonuclear -- does not require testing in the majority of cases, since its reliability may be established by analogy to previously tested charges based on the same physical and design principles. At the same...
...Test scores may tell you what students are learning, but not how they're getting that information," says Trudy W. Banta, a professor at Knoxville's Learning Research Center...
Most faculties, however, continue to test students without consciously analyzing what abilities they seek to foster, Adelman said. Advocates of ability-based curriculum feel that these educators force students to learn facts that are not critical in a world of rapidly developing information technology...
