This is the first book of the author I read. (Good dyslexic I will not venture to write his name). By gathering all my good faith and my jealousy very impressive career of the author, I would say the first half of the book is devoted to a sickening resume. After knowing with "the man", the second half is very exciting, and some passages are real small moments of happiness for science buffs a bit of a dreamer like me. The ubiquitous friendliness of the author also help to make this book a delightful read, humanist, and illuminating our universe. To put all hands, good or bad.
