An extremely well done review of a difficult book. Starts easily, then escalates smoothly into Lie groups. Then: > The discussion is rapidly getting technical, and if unimpeded, it is apt to become much more technical. The pedagogical challenge in all this is to communicate the elements of group theory to physicists in a way that persuades them of its use, and to mathematicians in a way that assures them of its honesty. LOL. This reminds me of the comment in Morse and Feshbach's two volume tome that (paraphrasing) "At this point the casual reader may have difficulty distinguishing the forest from the trees." I've been working on Schwichtenberg's "Physics From Symmetry", which is covering the same ground. It is really terse. I think I'll take a look at Woit.
