I think maybe it's worth no helping the audience gain this intuition that physicists have, that warm, wet things won't be quanta mechanical. A a quanta mechanics is the world, the whole world is quanti mechanical. But classical physics is a pretty god approximation to it. It becomes a very good approximation when things are big and radiating and so forth. And we can use entanglement as a touchstone. You mention that you think of entananglement as clearly quantum. I really do too. So suppose that we were interested in finding some biological system that makes use of entanglement. This entanglement would need to be concentrated and controlled between the few systems

Randomness and probability are central to modern physics. In statistical mechanics this is because we don’t know everything about the distribution of atoms and molecules in a fluid, so we consider a probability distribution over what they might be; in quantum mechanics it’s because the theory only lets us predict measurement outcomes probabilistically. Physicist Nicole Yunger Halpern explains how we’ve been lagging behind at bringing these two theories together, and how recent progress is changing the landscape of how we think about the microworld.
