My biggest problem with this book is that the title suggests material that is only covered in the last 10% of the book. I purchased it to get a lay person's view of string theory but the book hardly refers to string theory at all. It covers a lot of material in the first 90% that I was already familiar with and did not need another book to explain it all to me again. I was expecting a book that concentrated on events over more recent years, and not another book going right back to the beginning of quantum theory. In my opinion, the title misrepresents the content.
