Things I didn't need to know but wanted to know

At 493 pages on just describing physics, this book had a lot to say.  Knowing about theoretical physics is just fun.  It is also frustrating to get the beginning of the story and not have an ending, just a bunch of theories and ideas.  Is superstring theory really the way to go?  Will we ever be able to measure a Planck length?  So many questions without answers.  This book leaves more questions that a good literary book.

Though I enjoyed it, and was thrilled to find out Brian Greene has another book out, which I will be reading eventually.  This book sat on my shelf for over a year, I know this because it still has the Whatthebook sticker on the cover.
