Kapitsa, Allen, and Misener cooled liquid helium below 2.17 K and found it became a superfluid— flowing without friction, forming quantized vortices, forming density and temperature waves, flowing against gravity without viscosity, and conducting heat and electricity without resistance.
Thermal conduction in a superfluid looks like a sound wave. Instead of slowly diffusing through the liquid, it moves across the liquid in a wave.
A film of superfluid creeps up the side of its container against gravity, without friction, without sticking, and over the top.
The mind is meta; it models minds, steps back, sees its own reflection, and steps into a mirror. We think we know the mirror surface and its frame, but the mirror is reflected in another mirror.
