This is a well-blurbed book, and I really looked forward to reading it. Nearly as soon as it arrived I set aside everything to read it. What I liked about it was his open-mindedness and curiosity and playfulness. What disappointed me were the factual innaccuracies and just general lack of precision thinking. I learned a good bit about Kary Mullis, but I didn't learn much else. A very disappointing, weak book. Can't recommend it, although mericfully it is not a long read.
