...line with tax reform, the new 1040s will include five income brackets, instead of 15. Many of the intricate old deductions, including the write-off for state sales tax, are gone. But supplemental income schedules contain a welter of new instructions. What does the IRS, fresh from the humiliating recall of its W-4 withholding forms, have to say? The changes, pleads Arthur Altman, head of the IRS group that redesigned the forms, are a "reflection of what Congress has given...
...past. In the field armaments, the nonproliferation treaty has held the rate of nuclear diffusion to one-third the level that President Kennedy predicted in 1961. In commerce, the General Agreement on Tariffs and Trade has helped to slow the growth of protectionism. In banking, cooperation has worked to contain the threat of massive defaults and to manage the vast shifts of wealth brought on by the OPEC cartel. New opportunites for progress may exist in areas as disparate as protecting the ozone layer, stabilizing exchange rates, establishing rules for capital movements and trade, limiting nuclear weapons, or even...
...aircraft splintered into thousands of pieces over a wide area, most of them afire. Fire fighters and area residents dug ditches to contain the blazes, then began a fruitless search for survivors. "Doctors came, had a look and there was no one to save," said Zagorska. "Hands and legs were hanging from the trees." It was the worst disaster ever for the Polish national airline...
...many atoms, particularly those of metallic conductors, the outer shell has a number of empty slots, and the electrons that it does contain are not bound as tightly to it as those in the inner shells. Just as the sun's gravitational pull is weaker on distant Pluto than on nearby Mercury, the hold of an atomic nucleus is also weaker on electrons in the outermost layers...
...powers the sun), rather than splitting them. Key to one promising fusion process, which is under development in several countries, is a "bottle" composed not of any material substance but of powerful magnetic fields, generated at great expense by conventional electromagnets. Such fields are the only envelopes that can contain and squeeze atoms together at the hundred-million-degree temperature required to initiate fusion. But superconducting magnets, especially warm-temperature ones, could produce more intense fields at less expense and thus could "help make fusion power possible and practical," says Harold Furth, director of Princeton University's Plasma Physics Laboratory...
