John Harrison and the Problem of Longitude

History of the Harrison clock

Currently reading “Longitude” by Dava Sobel and gaining insight into the fascinating story of dead reckoning navigation and its deadly results. As a consequence, the Longitude Act sought a better way of determining a ship’s position in the sea.

I like this video because I wanted to see one of John Harrison’s chronometers in action. There is more history here than I had already learned from the book, and I saw his early clocks, wooden clocks, clocks without lubrication; fascinating to the mechanical side of my interests.
