This is great. Easy to follow lecture. Good speaker. Very complex subject though. -mp

Best explanation of superconductivity I ever heard

So wonderful energy ⚡

would a superfluid (a room temperature one of myth) feel like the absence of viscosity, like, would I feel that the air is resisting too much just above the fluid?

i want sir walter lewin everywhere in physics

Put nanoiron in the superfluid helium , have it spinning while in a inductive superconducting coil that is hookup to a variable resistor . power generation long as it remains in ON state or super cold. Until hans purple in a vacuum is figured out

can two pieces of matter occupy the same space at the same time... if that's what it takes to expel the magnetic field, yeah. The electric field at the edge of the superconducting region is changing as a charge builds up due to a current, since the magnetic field that causes is expelled the electrons *must* rush through the superconductor. So ... how or why is the magnetic field expelled?

Room temperature superconductor,,, hans purple ,a dye, in a vacuum changes its molecular shape into a 2d shape that is superconductive
