The premise of the book is that it is a series of lectures by Hawking and his mentor Roger Penrose. This was "the high point of a six month program held in 1994 at the Isaac Newton Institute for Mathematical Sciences at the University of Cambridge." I'm not sure where Cambridge is or what it's famous for, but I'm sure this was the hottest thing going in that half-year. The book itself is not a debate, only the last of the seven chapters. The first six are lectures alternately by Hawking and Penrose building up to the debate. If the seventh lecture was the high point of the program, the lectures certainly built up the dramatic tension in exactly the way universities don't build up dramatic tension.
The lectures are semi-non-technical. By that I mean that Hawking and Penrose can't help themselves and they put the pretty equations in the text for you to admire, but they aren't used for anything. So, really, they're nothing more than window dressing for the topic at hand. The topics are the classical theory of space and time (what is the future, what is the past, do they always exist?), singularities in space time (and some ideas about them), many varieties of quantum mechanical stuff (quantum black holes, quantum cosmology, quantum gravity), and twistor theory. Not necessarily light subjects, but presented in a way that most anyone should be able to understand.
And here both Hawking and Penrose get a chance to discuss some of their theories, like: why, exactly, would nature abhor a singularity? How exactly does it go about hiding them?
To be honest, the debate doesn't seem to be very heated when you get to it. It's just a restatement of the positions outlined beforehand, mostly. Not much "here's why I'm right and you're wrong." So, if you were waiting to find out who won the debate, I'm sorry: it wasn't that kind of debate.
----------------------------------------------------- I just noticed that Princeton is now putting this is a series call "The Isaac Newton Institute Series of Lectures," which is awesome. I want to read all of the books in that series. It's just that I have: there's only one in it so far, and that's this one -- which I read in its old Princeton Science Library format (a series that I love)
I'm sure the Isaac Newton Institute has brought some very engaging speakers in, and I was wondering if you'd help me bother them for more.
Mostly for myself, what I'm thinking about reading:
- Quantum Physics, Mini Black Holes, and the Multiverse: Debunking Common Misconceptions in Theoretical Physics (Multiversal Journeys) by Yasunori Nomura (Author), Bill Poirier (Author), John Terning (Author), Farzad Nekoogar (Editor)
- Quantum Sense and Nonsense by Jean Bricmont
- Quantum-Classical Analogies (The Frontiers Collection) by Dragoman and Dragoman A [started, actually, 7/28/2018]
