The ultimate book to start with on Physics and the Cosmos

This is the second time I have read this book.
The first time I read it what When it was first released in the eighties ... the updated 10th Anniversary version is pretty much the same thing with some added discussion on String Theory ... Basically more revised.
First of all, the book is not easy to read ... Especially for Those Who Can not clear Their Minds of everything to focus on what is being read. Without a clear mind you will be lost ... it takes common sense, good logic and quiet surroundings to successfully read the book in its Entirety.
Second, the topics covered are well laid out ... from relativity, to quantum mechanics, to the cosmos, to String Theory ... and even a chapter discussing our existence and how God fits into the picture. All in all, every chapter builds on the next very well, and the visual / "plain English" descriptions blend well with the scientific terminology.
Third, the chapter on string theory (Which was recently added) left me feeling a little hungry for more ... Although it Describes what String Theory is, I felt a lacking of Completeness ... probably due to the factthat this is a Newer field in theoretical physics.
If you are interested in theoretical physics at all, and wish to understand Einstein's theories of relativity and how the fit with quantum mechanics, then this is the book to start with. After having read this book you will feel the urge to get some other books discussing quantum mechanics, space-time warping, string theory, wormholes, and black holes.
Believe me ... Theoretical Physics is a very interesting subject indeed has been developed over many years by brilliant minds ... Those who are able to open Their Minds to what the cosmos and the universe have to show can Certainly achieve understanding ... Perhaps things and question further.
Enjoy!
