	From Wikipedia:

"Absolute zero is the point at which particles have a minimum energy,
determined by quantum mechanical effects, which is called the zero-point
energy."

	I guess one can define absolute zero your way as well - but then it
becomes physically unattainable.

	Don't know if Heisenberg stated it, but I think physicists believe it
does. What makes those universal laws and not this?
