@10:25 well yeah DD, I would completely deny that proof is physical. For we mathematicians who live in the physical world our proofs are communicated physically, so in that sense they are physical. But there is more to the subjective consciousness and mind than mere physics. Or so I would believe. It's not a scientific belief. But it is likely true. You cannot divorce the notion of mathematical proof from a mind that understands the proof, and understanding is (again _likely_ ) not a wholly physical phenomenon.
