over terminal screens and pore over mounds of studies for up to 16 hours each day. Their mission: to advance Japan one giant step in the world of computers, creating new ultrahigh-speed machines dedicated to that branch of computer science known as artificial intelligence...
...alert code would be instantly relayed by telephone, ultrahigh-frequency radio or teletype to the crews manning the 1,052 Titan and Minuteman intercontinental ballistic missiles in underground silos scattered across the Great Plains. At each launch site, the crew commander and his deputy would decode the incoming message separately, then make sure that the two versions matched. The two officers would open two combination locks to a safe; neither has the combination to both locks. If the sealed authenticator inside the safe matches the incoming message, the officers would take out separate firing keys and go to consoles about...
...after the Marconis and the Bell people and the Hertzes and the Maxwells raised their dust, and radiowaves with ultrahigh, superhigh or extremely high frequencies--those ranging in wavelength from 100 centimeters to a millimeter--became known as microwaves. These "microwaves" are very intense concentrations, "short-waves" of electromagnetic radiation focused into an intense beam. They travel through matter, can be reflected by electrical conductors, and can be directed accurately. Thus, microwaves revolutionized communication. They are responsible for television communications, radio (especially FM) broadcasts, CB radio, satellite communication, radar, sonar, and electric garage-door openers...
...tunnel back and forth through an insulator separating adjacent superconductors even when there is no voltage present-an idea totally at odds with the behavior of electricity at ordinary temperature; and 2) that if a voltage is applied across layers of superconductors and insulators, it will produce an ultrahigh-frequency alternating current. Devices based on the Josephson effects have already been used to measure natural phenomena like magnetic fields with unprecedented precision. In the future they may be the key elements in extremely high-speed supercooled computers (TIME, March...
...will drastically reduce the tax gap between regular income and investment gains. Thus ultrahigh-salaried taxpayers like corporation chairmen and pro football stars have much less reason than before to dodge taxes by converting, often through gimmicks like buying non-productive farms, part of their earnings to "capital gains." The law also chips away at incentives to make more conventional investments. Says George A. Kuhnreich, vice president of Ungerleider, Haidas & Co., a brokerage firm that services many wealthy investors: "It eliminates a good part of the rewards that used to be given to the long-term investor. It will mean...
