Very interesting--I like his graphical/geometrical approach.

He also talks about 'quaternions.'  I'm not a mathematician, but this isn't the
first time I've seen that subject mentioned.  Several months ago, I read a
fascinating mathematics book called MATHEMATICS: THE LOSS OF CERTAINTY by Morris
Kline (published in 1980.)  It's really a book-length essay, a kind of
philosophical discussion about the basic 'illogic' of some of modern
mathematics. The book has practically no hard 'math' equations at all (so I
actually read it cover-to-cover!) He talks about quaternions (and the earlier
calculus) as being a kind of 'breaking point' between the pure logic of previous
maths, and more modern constructs. Definitely worth a read.
