Did you ever play a game with yourself as a small child, "I wish..."  --- I did and I got very serious about it.  I very quickly progressed through the stages of wishing for a million dollars.  By the time I was a teenager I used to wish that I could understand everything in the universe.  By the time I was an undergraduate student in college I used to wish I could be arrested, put in jail for a few years and just catch up enough to do justice to the courses I was taking "THAT" semester.  By the time I was finishing up my graduate degree I used to wish I could get all the Mathematicians and Physicists in one room and force them to behave themselves and write some content that would give the rest of us a clue.  Since graduate school I have spent many many hours reading popular accounts of the latest 'bandwagon-theories' of mathematics and physics and loving every bit of it.  My wish slowly evolved to the point where I wished I could stay aware and awake enough to appreciate the new stuff as it came out.  Well; folks like Roger Penrose in this book and Brian Green in his two books and even Robert Laughlin in his book about emergent phenomena have basically granted my wish.  I really fell in love with Brian Green's books and found myself constantly flipping to the back of the book and reading the end notes and saying to myself, "Wow, wouldn't it be great if someone could sort of flesh all this out without requiring the reader to have a PhD in physics and math."  I read Roger Penrose's book The Emperor's New Mind some years ago and it only made me wish for more.  I can only applaud the Physicists and Mathematicians of our age for writing these types of books.  And I must say if you have even an undergraduate degree in math, physics, or any other physical science where you enjoyed the math and physics courses you took then this book is for you.  And even if you do NOT have a degree in math or some physical science but enjoy reading the best of the best then this book is for you.  I hope everyone will enjoy it as much as I have.
