Re: Ch. 5 - The Theory of Everything
I think this chapter is where the layman such as myself starts to get lost. On p. 107 he talks about renormalization, subtracting infinities, blah blah blah. By the end of the chapter, he is talking about different versions of string theory making up M-theory with eleven dimensions that has 10^500 solutions, and somehow this is supposed to correspond to 10^500 universes.
I should point out that I'm not saying that a very complex theory that is inaccessible to the layman can't be true (or a good model at least), but I'm critical of the book because he doesn't seem to making much of an effort to make the case for it, and we are left wondering why he is so enthusiastic and satisfied with this theory. Not to mention, as I've said before, whether his interpretation of all this mathematics is just poetic license. (I pulled a quote on this that I will post for the next chapter's thread)
