Query: Exceptional book!

I read so many books to put together the same facts I just found in one book: Big Bang by Simon Singh. I savored every single word. The way the book is written makes it easy to grasp the concepts, which were given an equal amount of thought and consideration. The summaries at the end of each chapter, as well as the tables of comparison, constitute an efficient way of serving the objectivity with which these topics are discussed throughout the book. Loved it, loved it! I highly recommend it to everyone who loves science in general, this including old and new theories alike.
