These Clocks Helped Measure the World

At The Royal Society in London, Adam takes a look inside a few special timepieces that were used by Captain James Cook during his voyages traveling the world. These regulator clocks and chronometers were used as a way of timing the transit of planets across the sun and coordinating those observations with others made around the globe. They weren't just timekeepers, but important scientific instruments on Cook's expeditions that still work to this day!
