Query: Very interesting

I am almost done with this book, and I liked it very much, he seems like he would have been a great teacher, the kind who would have made class interesting. I read it, and I can almost get how the universe works. Obviously, it is too simple for those with a physics background, but for those who merely have an interest, without the background it can be helpful-I would almost recommend it as a supplimental textbook for an intro to physics book, makes me wish I had had this type of book when i was in college.
