It's an excellent book.

Longitude particularly made me appreciate the craftsmanship that these inventors applied. Could you imagine spending 20 years building a single machine, not sure if it was going to work, then sending it off on a boat for 2 years and only when it comes back do you know if it worked? Makes me a bit more patient to wait 2 minutes for the test suite to run...
