There was one person at Caltech who wrote a review which said my book should virtually be banned from children, because it will keep them from going into science. Maybe this person went into science for different reasons but, certainly, that hasn’t been the effect. Most people who read the book say it was fun, and people say it inspired them to go into the field. So I don’t think that touch of reality really — but some people thought “this is evil,” and I didn’t.
