...Hiroshima Peace Center. * Finished in stages during the early 1950s, the complex is a complete preview, in miniature,of Tange's architectural career. Nearly all of his low-rise, high-modern ideas are on display: the International Style box, the inverted cone, the rough concrete pillars, the swooping concrete shell. The details have a light touch; the forms are blessedly simple. Tange's best designs embody heavenward sweep, a figurative and literal uplift. The central feature of a printing plant in Numazu (1954) is a great set of steel trusses, a wing- like cantilever from which the factory's glass...
Working with Illinois Bell, McDonald's is now using ISDN technology to link its Oak Brook, Ill., headquarters with its Chicago regional office. Tenneco and Shell Oil will begin tests by early next year. To the consternation of the local and regional Bells, a few companies, including Westinghouse and the Travelers insurance firm, have installed their own ISDN internal systems. The Bells are concerned that they may lose some of their largest customers if more companies follow suit...
Some astronomers are in less of a hurry, figuring that the best is yet to come. Says Woosley: "Once the photosphere ((the supernova's luminous surface layer)) is gone, that's when it gets interesting." When that shell thins out, months or years from now, astronomers will be able to look inside and "see" the newly born, rapidly spinning neutron star, but with a radio telescope rather than the optical kind...
...last week scientists had already amassed more data than they could immediately analyze, confirming some theoretical predictions and making several observations that for the time being puzzled everyone. Earliest readings showed that the shell of gases expanding around 1987A was initially traveling outward at nearly 10,000 miles per second. Since then the color of the supernova has been changing from blue to red much faster than expected. "That change is five to ten times faster than other supernovas," says Robert Williams, director of the U.S.-financed Cerro Tololo Inter-Observatory in Chile. This phenomenon indicates that the rapid expansion...
...core contracts, however, its internal pressures will rise, forcing the temperature rapidly back up again until the intense heat ignites the unfused hydrogen gas surrounding the core. The interior of the sun will now be hotter than ever, a dense core of incandescent helium surrounded by a thin shell of hot, fusing hydrogen. Over the next few hundred million years, heat from the core will drive surface layers of the sun so far outward that they will cool to about two-thirds of the current 6,000 degrees C surface temperature, and redden. The sun will have become...
