The previous reveiwer who suggests that this book is being removed and that Stephen Hawking does not want it published has got it entirely wrong. What he refers to is a completely different book. Universe in a Nutshell is a new work based on Hawking's new theories and the author and illustrators spent two years creating it. I know this because I was responsible for the artwork. It's a pity that so-called reveiwers are so ignorant and loud-mouthed without having the knowledge or intelligence needed to make comment.
