Title: Failure to explain
Review: I was really disappointed by this account. I've long been a fan of Harrison's chronometers since I found them in the maritime museum at Greenwich. The book just fails to explain what was different about them that enabled them to win the prize. The essence of the solution of the "greatest scientific problem of his time" is simply never addressed. I could summarise all the book has to say as "Harrison made a better clock"; it doesn't explain how or why it was better.
Is the review positive or negative?
