I agree with the above - I've just started using this book myself, and there really aren't that many passages, compared to other books that are out there. However, I'm finding it extremely helpful so far. Each chapter is explained in simple and manageable terms, and the problems at the end work you up from very simple to a few passages; I really strongly dislike physics (I'm even a little scared of it) and I've been finding that the way this book is set up gives me some much-needed confidence.
