The Wikipedia definition of a super fluid is:

Superfluidity is a state of matter in which the matter behaves like a fluid with zero viscosity

As a fluid dynamics guy, I have a hard time imagining a zero viscosity fluid. Does superfluids have near zero viscosity, or exactly zero viscosity? A big of context explaining where the "loss of viscosity" comes from would be great.

  • An "electronics guy" might also have trouble imagining a zero resistance conductor, yet superconductors are precisely that. In both cases, the origin of the zero value are quantum effects. – ACuriousMind Feb 20 '16 at 23:00
