    i always heard of the term superconductor alot, wherever i read Quantum mechanics articles and many others. What puzzles me, is the fact that i cant make much sense out of what they actually mean, and how they work.

    can anyone give me an outline, or just a brief description of how superconductors work??
    thanks~

    A super conductor is a conductor with very little or no electrical resistence. Most super-conductors work at only super-cool temperatures.

    If you are looking for a more scientific and mathematical definition then someone else will have to asnwer this question.


    The hand of time rested on the half-hour mark, and all along that old front line of the English there came a whistling and a crying. The men of the first wave climbed up the parapets, in tumult, darkness, and the presence of death, and having done with all pleasant things, advanced across No Man's Land to begin the Battle of the Somme. - Poet John Masefield.

    A superconductor is a material with ZERO (not just very close) electrical resistance.

    The explanation is not simple, and in some cases not understood. In many materials it is explained throught the mechanism of "Cooper pairs".

    John Bardeen received his second Nobel Prize in physics for work on the theoretical basis for superconductivity.

    It comes up in talks on QM because it can't be explained without QM at all, at least not as far as I know.

    Conductivity, super or otherwise, is determined by the solid state structure of matter, and that can only be addressed via quantum mechanics.
