Tide Predicting Machines

This lovely machine was built by Lord Kelvin in 1872-3, an early analogue computer.

Check out this German tide predicting machine! It turns out that predicting the tides is actually very difficult--"Tides are still one of the most difficult problems which modern geophysics has to deal with. Research institutes involved in tidal prediction are equipped with top of the range, high capacity computers."
