More fundamental is the fact that while the new ceramics remain superconductors at high temperatures and can withstand intense magnetic fields, they can as yet carry only about a hundredth of the current capacity of conventional superconductors. And because the amount of current flowing through the magnetic field determines its strength, scientists are concerned that a quick fix may not be in sight. Warns GE's Robb: "What we need now is a second invention that would modify copper oxides to allow high currents to flow at high temperatures. There's a fifty-fifty chance that second invention will ever...
...even the best of ordinary conductors have some resistance to the flow of electrical current. The reason: as current passes through, some of the electrons collide with other electrons, thus dissipating their energy in the form of heat. According to the BCS theory, these collisions are avoided in superconductivity. "What causes a material to become superconducting is a phase change,"* explains Bardeen, now a professor emeritus at the University of Illinois. "You can think of it as electrons condensing into a new state." That state involves the pairing of electrons and a kind of group discipline...
...face it, the only people excited by the details of Swiss bank accounts are the Gnomes of Zurich. So let the committee counsels do this work for you. Otherwise, warns Republican Media Consultant Roger Ailes, "you could end up looking like a chief financial officer discussing the cash-flow management for the coming marketing season...
...finger pointing was inflamed by the conflicting reports surrounding Linder's death. Eyewitness accounts reaching both Managua and the U.S. suggested that Linder and some government workers were measuring the water flow of a stream in a northern village when a band of contras struck. The contras claim that a fire fight ensued, a distinct possibility since the Sandinista leadership encourages Nicaraguans to carry weapons in war zones in self-defense. The rebels regard anyone armed or in uniform as a combatant, though the Sandinistas view many of the same people as civilians. It remained unclear whether Linder, who sometimes...
That could be disturbing for Apple, which needs a steady flow of fresh software for products like the Macintosh. So last week Apple announced plans to set up a well-financed, independent software company that could eventually rank among the industry's top five producers. The new concern will initially develop software only for Apple machines under an unspecified non-Apple name. The company will aim in part to seek out hot new ideas from small-time independent programmers who lack the resources to market their products. So, just like Apple's first computer, the next software breakthrough...
