    The incorrectly buttoned shirt is a marvellous example of displacement! ;)

      No, the point that it illustrates is 'broken symmetry' -- didn't you follow the details of the interview?

    Electrons in the conduction band at low temperatures are combined into a Bose-Einstein gas, which has the property of superfluidity, therefore, the so-called superconductivity is actually superfluidity of an electron gas without the resistance of the crystal structure. The ability of a substance in a special state, which occurs at temperatures close to absolute zero, to flow through narrow slits and capillaries without friction. This is superfluidity.

      Does not make sense. Superfluidity is about liquid flow without kinetic energy dissipation, superconductivity is about electrons moving through a solid.

      @@bhadeshia123 Conduction electrons move only in the conduction band of the crystal. It can be represented as an averaged capillary.

    brillinat person, thinking differently
