Lost at Sea: The Search for Longitude (#2511)

It was one of humankind's most epic quests - a technical problem so complex that it challenged the best minds of its time; a problem so important that the nation that solved it would rule the economy of the world. The problem was navigation by sea - how to know where you were when you sailed beyond the sight land - the finding of your longitude. While the gentry of the eighteenth century looked to the stars for the answer, an English clock maker, John Harrison, toiled for decades to solve the problem. His elegant solution made him an unlikely hero and remains the basis for the most modern forms of navigation in the world today. This film is both a celebration of Harrison's invention and an adventure story. An expedition on a period sailing vessel as it journeys to the open ocean will demonstrate the life and death importance of finding your longitude at sea. [56 minutes] Closed Captioning
