...powerful laser, which is housed in cavernous quarters the size of a football field. The juxtaposition of the two objects is apt, and for several reasons. Like Shiva, the $176 million laser bristles with its equivalent of arms: ten bright blue tubes, each a conduit for an intense laser beam. And like Shiva, Nova will dance to a schizophrenic tune: it could benefit life --and perhaps help to destroy...
After the giant laser is dedicated in a ceremony at Livermore this week, scientists will employ its intense beam of light in an attempt to weld the nuclei of hydrogen atoms, releasing bursts of energy at temperatures exceeding those at the center of the sun. Should they succeed in harnessing nuclear fusion, they could point the way toward a limitless supply of cheap, clean power. "Once we crack the problem of fusion," says John Emmett, associate director for lasers at Livermore, "we have an assured source of energy for as long as you want to think about it. It will...
...bombs cannot be exploded in power plants, and when Lawrence Livermore scientists begin their experiments six weeks from now, they will use powerful laser beams instead. In Nova, under the guidance of more than 50 computers, a pulse of light is whipped around a master oscillator until all of its wavelengths are identical and in phase. The pulse of pure laser light is then split into ten parts, each of which races down its own 460-ft.-long tube equipped with amplifiers, spatial filters and isolators. As it emerges, each beam is focused to about the width of three human...
...notably telegrams and telex, remain profitable but have come under pressure from new rivals like in-house corporate message networks. In seeking other opportunities, Western Union has gone off in an unwieldy number of directions. Its ventures have ranged from making mobile- telephone equipment to building ground stations that beam messages to satellites...
...World Trade Center by firing a rifle bullet from the top of the John Hancock Building in Chicago. The sensors also would have to flash back instantaneous assessments of what targets had been hit, so that a battle station would not waste vital seconds aiming a laser or particle beam at a missile or warhead already destroyed...
