Main Question or Discussion Point
The "Universe In A Nutshell" (okay, for all you picky people out there, I know I shouldn't have underlined and quoted the title to be grammatically correct...) is an excellent book for an intermediate learner of theoretical physics. And that's what I dislike about the book, it'd be hard to understand for people who have little background in physics. Believe me, I tested it on my sister. Anyhow, it uses great anologies, and Stephen Hawking (the author) consistently describes things from quite a few views: Positivist, and non-positivist, are the most common ones.
