While your carry-on is being X-rayed, you step through the metal detector. It screeches. You dump your coins in a tray and try again. Screech. You remove your metal-rimmed glasses. Screech. As other latecomers fidget behind you, you remove your belt -- and finally pass through. The machine is so sensitive that your tiny buckle...
...other and emptied of air. A laser, placed at the intersection of the pipes, will emit a beam that is split into two parts, each of which will bounce back and forth between suspended weights and finally return to the intersection. There the beams will be recombined, and a detector will examine them for slight distortions that will reveal whether movements of the weights have forced one light beam to travel as little as one ten-quadrillionth of a centimeter farther than the other, a likely signal that gravity waves have affected them...
...elevator doors opened into a cavernous room in an underground tunnel outside Geneva. Out came the eminent British astrophysicist Stephen Hawking, in a wheelchair as always. He was there to behold a wondrous sight. Before him loomed a giant device called a particle detector, a component of an incredible machine whose job is to accelerate tiny fragments of matter to nearly the speed of light, then smash them together with a fury far greater than any natural collision on earth...
...physicists, who will have no trouble finding jobs even if the SSC construction were to stop suddenly, the lure of the giant collider is irresistible. In fact, the leaders of the 500-scientist teams that will eventually run the SSC's enormous detector experiments are already beginning to organize. One such collaboration is being formed by Ting. Politically shrewd, he has wooed physicists from a number of weapons laboratories and Southeastern universities, which until now have not been powers in the field of particle physics. Observers expect he will run the experiment in the strictly hierarchical fashion he has displayed...
