i t ate out of it my first quarter at u. C l a to 18 and 19 year olds, i would answer every question at the back of each chapter just in case they ast - which they never did. But i thought, this is too hard for these undergrads. And sure enough, i think that was true. When people look at that book, if you leave through it in its physical formit doesn't look like a modern graduate text book because there are not many equations, if any. It's actually a literary work as well as as a text book.
