Absolutely excellent. The best explanation of quantum mechanics ever and this from an undergrad business major with a master's degree in writing who dabbles in 'weird science' to stretch her brain (and to write convincingly--a factor she's not yet proven). I've recommended this to the very few people I know who also love the challenge of modern physics or those who simply cannot help themselves when it comes to weird science or those who thirst to understand the basis of life. Next time I'm in London, I'm going to look these guys up. A true wow! And also a bit gutsy, especially the ending.
