In 1872, William Thomson develops a way to combine the movements of multiple pulleys through one flexible connection. The result: a machine built to calculate tidal patterns through mechanical motion. #TidePrediction #MechanicalEngineering #EngineeringHistory #ScienceHistory #Inventors

Predicting tides takes more than tracking the Moon. Lord Kelvin saw that overlapping cycles of the Moon, Sun, coastline, and sea depth could be modeled as simpler repeating movements. #ScienceHistory #LordKelvin #TidePrediction #OceanScience #Mathematics
