The solution to this problem was continued at an exhibit down the hill at the National Maritime Museum. In 1714, the British government offered a reward, equivalent to £2 million today, to anyone who could solve the problem of finding longitude at sea. Possible solutions were developed that involving time-keeping, lunar distances, magnetism, signaling and Jupiter's moons. It took almost 60 years for the prize to be awarded and in the end, time-keeping proved to be the best way, although lunar distances did work for some time.
Friday was our last full day in London and we spent it checking out a couple of exhibits at the British Museum and the Tate Britain. We finished off our time in the UK by going out for one last family dinner in London. It was definitely sad to say goodbye to everyone and leave the UK.
