Usage examples of superconductivity.
Anderson, an expert in superconductivity and solid-state physics, was visiting Cambridge for the year while on sabbatical from his position at Bell Laboratories.
Luckily, that volume has already been written, following in great detail the path from the Egyptians to modern times, including the strange effects of Meissner fields, superconductivity, and magnetism.
Once upon a time, superconductivity had been associated only with utter cold, near absolute zero.
She treats the roiling, surging channels of superconductivity far below as she formerly did the highways and byways of the Net, as yet another domain to rule by proxy, by subroutine, by force of will.
Today we understand superconductivity to be an intrusion of quantum mechanics into our everyday, macroscopic world.
Instead, superconductivity relies on a subtle mechanism that prods the electrons to join in pairs, at which point they become bosons and lose all inhibition.
As of this writing, the physical basis for high-temperature superconductivity remains an enigma.
Even in its original low-temperature form, superconductivity always offered great economic and energy-saving promise.
That was one reason why the discovery of high-temperature superconductivity caused such a stir: The critical temperatures could now be reached by cooling with liquid nitrogen, which is both cheap and abundant.
Yet Josephson seemed to be suggesting he understood the theory of superconductivity better than its creator did.
His entry to the field came when he began collaborating with Peter Hadley, a graduate student at Stanford University, and his adviser Mac Beasley, an expert on superconductivity, who had already realized that nonlinear dynamics should have something to offer to the analysis of Josephson arrays.
Kreef managed to perfect room-temperature superconductivity, Spock said, the Joy Machine is clearly big enough to perform almost any function necessary.
Luckily, that volume has already been written, following in great detail the path from the Egyptians to modern times, including the strange effects of Meissner fields, superconductivity, and magnetism.
Not the parlor magic stuff of superconductivity, but a real low-cost system that would negate mass and resistance.
Until late 1986, superconductivity was a phenomenon never encountered at temperatures above 23 K, and usually at just a couple of degrees Kelvin.
