...estimated ten tons of earth brought out from the 130-ft. tunnel (about 2 ft. high by 2 ft. wide) had been shoveled into an intersecting tunnel that was used for a 1931 prison break and never filled in. The guerrillas had even managed to rig a plastic and cardboard bellows to provide air to the diggers...
...conservatively dressed man with graying hair strode unflinchingly to the target area of one of the world's most powerful nuclear particle accelerators last week and donned a molded plastic mask. At a signal, the accelerator beam was switched on, and nitrogen nuclei, traveling at almost the speed of light, flashed into his temple through a hole in the mask. At first nothing happened, even though the beam struck his optic nerve, behind the retina. For the next pulse, however, his head was moved so that the beam passed through his retina. "Hey, there's one!" he shouted...
...step in bringing the universe down to earth. Like cosmic rays from outer space, the particles shot through the Bevatron are really bare nuclei of atoms-in this case nitrogen-that have been stripped of their electrons and accelerated to tremendous velocities. By shooting these tiny bullets into a plastic target rich in hydrogen atoms, the Berkeley team was able to dissect the laboratory-produced cosmic rays. The collisions fragmented the nitrogen nuclei into every element lighter than nitrogen in the periodic table. By analyzing the results of this and similar experiments, physicists hope to bolster their meager store...
...purveyors of plastic credit prefer to absorb the cost of stolen cards -which last year amounted to well over $50 million-rather than claim the $50 per victim to which the law would entitle them? Credit card executives are vague on that question. But staffers at the FTC's Division of Consumer Credit and Special Programs say that most companies have a lot to gain by keeping their customers uninformed. If a cardholder knows that his liability is limited to $50, for example, he may not be so prompt in letting the company know when he finds that...
Expected to sell for about $10 when it appears on store shelves this week, the kit consists of a blue plastic tray of diluted chemicals, four test tubes, five "dropping bottles," a funnel, magnifying glass, microscope slides, a smoke chart and parts for assembling a "smoke trap." One of the experiments described in the instruction booklet shows children how to test the effect of phosphates on algae by adding fertilizer to pond water in a jar; another calls for testing the acid or alkaline content of water in their home washing machine by putting five drops of a chemical (called...
