Negative Positive
Title: Excellent popular history
Review: This is an interesting, well-written popular history of the creation and development of the chronometer, which ultimately solved the longitude problem. The illustrated version of this book provides the pictures, drawings, and diagrams that were sorely needed in the original book by Dava Sobel. By the way, the inventor's name was JOHN Harrison, not William (as stated in the Amazon.com review) and not James (as stated in one of the reader reviews).
Is the review positive or negative?
