I loved this book---it made quantum mechanics fun and dicipherable, while revealing Niels Bohr as a person, not merely a scientist. The drawings help convey a sense of the people and their personalities---I wish this had been available while I was doing high school physics, it keeps the interest up rather than reducing it to math, like we did in class. The novel also places Bohr in the context which he lived---the matrix, if you will, that produced him.
