About to start on "Gravity’s role in quantum state reduction". In most physics books, this chapter would be considerably shorter.

"Holomorphic sheaf cohomology isn't really so hard". This appears to be the punchline to one of the book's better running jokes.

Okay... twistors are starting to make more sense. In twistor-space, light-rays are points and they intersect at events. But the math is still very hard to follow.

Twistors. Well, I think I just about understand what they are, but I don't see why they're so wonderful. He promises to explain.

Why the graviton has spin 2 - I had wondered about this! Unfortunately, I'm only understanding perhaps a quarter of the math. This chapter is incredibly hard.

Did I say he was dissing string theory? Actually, he'd barely got warmed up when I wrote my last post...

Withering criticisms of string theory. The thing that annoys him most (it's a close-run thing) is that it's being promoted as a theory of quantum gravity, yet fails even to address the problems which most interest the gravity community. Not hard to see why the string theorists hate him.

He doesn't believe in supersymmetry either. I'm looking forward to hearing his views on Santa Claus and the Easter Bunny... maybe they'll be in the final chapter?

Oh my goodness. Penrose casually reveals the answer to Life, the Universe and Everything. Though it's possible not everyone in the physics community agrees with him.

The vexed question of whether information is lost when things fall into black holes. Penrose says that's obviously the case, and any other conclusion is just wishful thinking from theoreticians feeding their pet theories. But it looks like he's about to throw a large chunk of red meat to one of his own pets...
