More on Penrose

I had missed that Peter Woit had favourably reviewed Roger Penrose's new book a few weeks ago.   Go have a read.

(It's interesting, the discussion about Penrose's issues with inflation.  I always had the feeling that this seemed to be a solution that was widely accepted before the mechanics of how it could happen were even guessed at, which seems to be a somewhat backwards way to work compared to most of physics.  Well, at least for a phenomena that isn't actually being observed but is being inferred. Was my hunch right?)
