Query: Great Introduction to Physics

I love reading Feynman. I am not going to write a long review of this book. If you are interested enough in physics to be at this page, then reading this book is a no brainer. I will say that I read QED first, and that is Feynman's masterpiece. This work suffers by comparison only in that he is addressing underclassman and trying to get them interested in the big picture, whereas QED is the big picture. The great thing about this book is its conversational tone. You can almost imagine yourself in a classroom headed by the most brilliant physics teacher or our time. That's worth something, I'd say. Enjoy.
