...precision holes through materials as hard as diamonds in a small fraction of the time required by conventional methods. It can vaporize the rough edges of such microscopically small products as integrated circuits. A less powerful laser beam can weld wires and other delicate metallic parts without damaging nearby heat-sensitive parts...
...precision and penetrating power of laser beams have, as predicted, given them entree to the operating room, where they can cut into human and animal tissue as delicately as a finely honed scalpel. Even better, the laser knife does not draw blood. Its searing but highly localized heat cauterizes capillaries and other blood vessels as they are severed. Like ordinary light, laser beams pass through transparent substances but are absorbed by darker, opaque materials. Thus they flash harmlessly through the cornea and lens of the eyeball to weld a detached retina back into place, or puncture small holes...
...Others have gone beyond the early idea of a death ray and suggested that laser beams may eventually be powerful enough to provide the ultimate defensive weapon against missiles. Powerful laser beams, they predict, might well make iCBMs obsolete. Focused on an incoming missile, their light would generate enough heat to melt it into uselessness...
...style could be purchased, Norman Jewison, normally a versatile, canny director (The Russians Are Coming, In the Heat of the Night), would surely have included it. Unable to do so, he has turned out a glimmering, empty film reminiscent of an haute couture model: stunning on the surface, concave and undernourished beneath...
While the lights had the misfortune of drawing Cornell in the first round of their meet, the heavies--in their quest for the big prize--have it easy today as Vesper and Penn slug it out in the first heat. Harvard meets no-contest boats in the other heat...
