I hope this is not too inappropriate, but I generally consider these forums to be of a very friendly nature and didn’t know where else to ask.
Has anybody read or have an opinion on Penrose’s new book ‘The road to Reality’?
I’m thinking of getting it, it looks like it tries to properly tie in the underlying mathematics of theories in physics unlike other books in the popular science genre. Am I right in this or do you think that I will be left unsatisfied? (To give you an indication I have some mathematical skill, I have experience with differential equations (ordinary/partial) and some with non-Euclidean geometry etc… but of course mostly forgotten but understood it at the time.)

I didn’t know about R.P.'s new book,i’m glad to learn so
I read early this year Penrose’s The large the small and the human mind, very interesting and intelligible book, i even wrote a review on amazon.com.
Now I’m into The Emperor’s new mind, many things are discussed it seems brilliant, i hope i’ve the free time to read his new one too
since i found some interesting review here:

I’m Reading Road to Reality at the moment and have a similar background to the topic starter. Penrose does not hold back with the mathematics at all. He proves things which are easy (Pythagoras, irrationality of root 2) but skips proving anything which is hard or tedious. For instance, he tells you that the differential of x^2 is 2x but does not prove it. This allows him to start using notation like dx/dy after a few pages of explanation rather than 20. He takes a similar approach through much harder equations involving tensors and spinors. This is superb becuase you get to understand ‘the real’ equations that people like Penrose are using day-to-day. If you want formal proofs of the harder equations then Penrose gives excellent references.
