Re: Heisenberg and his Principle (and how it relates to paleontology)

Such stuff is still far too big for statistically significant contributions
from HUP, I'd say. It might, say, increase the noise in a mass spectrometer,
but this is a total guess.

Roger Penrose's (I think; can find a ref) suggestion that in the microtubuli
of (nerve) cells a superposition of quantum states (a direct consequence of
HUP) can establish itself and cause random, free will etc. is very, very
interesting -- but later I read somewhere that even microtubuli are too big
for that.
