While concern over computer security has garnered headlines in recent . weeks, veteran users tend to take the matter in stride. "There is no such thing as privacy on a computer," says Thomas Mandel, an analyst at SRI and a regular on several Silicon Valley computer networks. "The view here is that if you don't want something read, don't put it on the system...
...long. The instant the remaining silicon in the core is fused into iron, the thermonuclear reactions stop. Without enough radiation pressure to sustain it, the now all-iron core, hidden under the star's outer layers, begins its final, catastrophic collapse. In the incredibly short time of just 1 second, according to University of Arizona Astrophysicist Adam Burrows, the core is compressed to more than the density of an atomic nucleus. "It's as if the earth had suddenly collapsed to the size of New York City," says Burrows. "At this point the rest of the star is oblivious...
...Harvard's Robert Kirshner, the temperature of 1987A's expanding shell should drop from its current 10,000 degrees C to roughly 6,000 degrees C, about the same temperature as our sun's surface. During the explosion, though, internal temperatures climbed to billions of degrees, and elements like silicon, sulfur and platinum, synthesized by the star, began spewing out over a vast region of space, where they will form clouds of gas and dust that can coalesce into new stars and planets. Indeed, most of the elements abundant on earth today, except hydrogen, were cooked up in some star...
When H. Ross Perot was forced off the board of General Motors last December, many people wondered where he would park his $700 million settlement. Some of the money showed up in Silicon Valley last week: Perot announced he was buying a stake in Next, the computer venture of Steve Jobs, the co-founder and former chairman of Apple Computer. For $20 million, Perot, 56, joins the Next board and gets 16% of a company that is at least a year away from shipping its first product. Jobs, 31, will keep 63% for himself. "We feel we can call...
...problem by Harris Pastides and Edward Calabrese of the University of Massachusetts at Amherst's division of public health. The two investigated a group of 744 women and found a somber correlation. Pregnant women working where nitric and sulfuric acids were used to engrave circuitry patterns on silicon wafers experienced a miscarriage rate of 39%, vs. the national average of roughly 20%. Even though it has long allowed pregnant workers to transfer from such areas, Digital says, its study is inconclusive. "We have the data," says Spokesman Jeff Gibson, "but we have no way of drawing any causal inferences from...
