Noble prize, afterward.
Superconductivity was explained like decriesing of resistance thank to some hypothetical phonemons, yielding by material of superconductivity, which are kind of oil , making free conducting without resistance.
I say , there is circumstances of fenomena SASER into material of superconductivity, because of different magnetic exiting of electrons in different atoms , cooperating in superconductivity material . And this SASER would suppress fluctuations of material at the time of electricity conducting.
