Bullard, who was knighted in 1953, pioneered study of the earth's magnetism and heat flow through...
...pure). They reasoned that any electrons donated by the impurity would tend to migrate to the adjoining undoped gallium arsenide layer because of their tendency to seek what physicists call a lower energy state. Explains the Australian-born Dingle: "It's rather like the inclination of water to flow downhill." The new design worked. Isolated from the obstructing impurities in the alternate layers, electrons flowed at unprecedented velocities through the gallium arsenide layers: nearly twice as fast at room temperatures, and as much as 20 times as fast at lower temperatures...
...level. But Dingle see many practical future applications, ranging from stereo set components that require less energy to a new generation o high-speed computers and telephone transmission systems. Even more dazzling devices may be in the offing. At present semiconductors are flat; their electrons, for all practical purposes, flow in a single plane. But with the new layering technique, Dingle foresees three-dimensional devices in which electrons flow in all directions. That could make possible even tinier circuitry that would make today's minuscule computers look like veritable dinosaurs...
...energy bill permits natural gas prices to rise significantly, leading to total decontrol in 1985, and meanwhile imposes the same pricing system on gas pumped and sold within a single state and fuel piped across state lines. Energy executives in Houston forecast that as a result, more gas will flow from producing states like Texas and Louisiana to homes and factories in the North and Midwest, where gas ran desperately short the past two winters...
...weakness in the haphazard process is that solutions that worked once may be tried over and over again in situations requiring entirely different resolutions. Most economic forecasters, however, accept the traditional notion that firms seek to maximize profits. If that is not so, then the economic policy decisions that flow from their forecasts, both in and out of government, are to say the least, questionable...
