...linear collider (SLC), built in a hurry (3 1/2 years) and on the cheap ($115 million), has been struggling since February to measure the Z 0. Despite delays in getting the machine up and running, physicists at the Stanford Linear Accelerator Center, in California, have already produced 120 Z 0s. That is enough to calculate the particle's mass more accurately than ever before. And by the end of the year, when the number of Z 0s produced is expected to reach 2,000, the Stanford scientists think they could have the Z 0's life expectancy pinned down...
...work from the start. The positrons and electrons in the LEP are made to circle repeatedly in opposite directions through the tunnel, with new particles added periodically to the stream. In a given period of time, the LEP is expected to produce hundreds of times as many Z 0s as the Stanford collider does. That gives CERN the best odds of being the first to measure the Z 0's life-span...
...heart of the new features are computer circuits that change standard analog TV signals, which are broadcast as a series of undulating waves, into digital impulses -- strings of 0s and 1s. The digital signals can then be transformed by microprocessors -- tiny computers on silicon chips -- to achieve a variety of exotic effects. When the processing is complete, the signals are changed back to analog for display on an ordinary TV picture tube...
...enhanced when an entirely new transmission technology, known as the Integrated Services Digital Network, is put into place across the U.S. Currently, most phone service is based on analog transmission, in which voices and data are carried by ordinary electric currents. ISDN uses a dense stream of digital signals: 0s...
