just finished Susskind's QM. Definitely blew my mind. Can't stop wondering about commutators. Trying synthesize and remember with self quiz I can't self grade.
Super quiz: Could one in principle calculate the number of Planck flops (commutaor operations or bits) in a human lifetime?
My answer: Sure, the Planck unit is the quanta of action. If one were just to consider the position-momentum basis (to keep it simple), and assume a person is at all proper seconds "located" (because wherever you go there you are), and assume that a person is always a set number of massive quanta (surface area*kg) you could calculate how many non-commutative decisions were made to localize their position in space over some proper time interval - in other words how many [x,p] plank-sized commutator bits were left behind as "lost energy", or added as "einselections" (depending on your preference).
