  A magnetic field H is expelled from the interior of a metal becoming
superconducting. Everybody thinks the phenomenon is perfectly well understood,
particularly scientists with the highest H-index think that. I don't. I will
explain why I believe that without Holes, conceptualized by Heisenberg in 1931
fifty years after Hall had first detected them in some metals, neither magnetic
field expulsion nor anything else about superconductivity can be understood. I
have been a Heretic in the field of superconductivity for over 30 years, and
believe that Hans' little story about the emperor perfectly captures the
essence of the situation. Here is (a highly condensed version of) the wHole
story.
