Right.

When you have a medium such as an atmosphere to do that.

Cool breeze.

Yeah, the cool breeze will cool you down faster than just you radiating your heat.

You're radiating it away, your whole heat.

Okay.

It's slightly different.

The cool breeze is forcing your sweat to evaporate, and the evaporation takes energy out of you.

But, so let's get back to...

to the absolute zero.

So I keep taking heat out and the temperature gets lower and lower and lower.

You reach a point where quantum phenomena dominates and you can no longer use classical reasoning.

This, by the way, Dalton was not alone in this intersection, this troubled paradoxical intersection between classical physics and what we call modern physics.

So you get down there and you try to take more heat out and you can't because, and by the way, taking heat out means that particles are moving slower and slower.

The heat is vibrational energy typically.

So you take that out.

And there's a regime where the quantum fluctuations prevent it from ever stopping its motion.

All right?

Okay.

So you're saying, let me...
