I read that book in college and loved it. 

 

 

The story of John Harrison has been turned into a book, a movie, and a tv mini-series! All called Longitude. I liked the book!

 

 

 

Found this article today about a 250 year old mechanical pendulum clock design that keeps near perfect time (loses less than a second every hundred days).

You may be asking yourself, “Why am I getting an email from a GIS listserv about a clock?”  Well, it’s because the clock designer was John Harrison, who was a leading figure in creating maritime chronometers for determining longitude for ocean going navigation.  Very interesting man.  Worth a Google search.
