Penrose and Entropy

rev.goetz

Roger Penrose calculates entropy by the number of photons per baryon.
And whenever I asked a physics graduate student about this, they where
not sure why. I wonder if it makes more sense to calculate entropy by
the number of photons per gluon. Does anybody know why Penrose
calculates entropy by the number of photons per baryon?

This is a VERY complex issue, for a rough guide where to start try the
Princeton University: WebMedia - Lectures.
