In 1950 they built the Doodson-Légé Machine, which runs under similar principles but with many more variables.

This one is operational and they ran it up for us. 🌊🖥️

We were there to get a guided tour of their old tide calculators - mechanical analogue computers that were used to predict tide heights around the world.

This is the Roberts-Légé Machine, built in 1908. It was used to predict the tides for the D-Day landings (among many other things)

Researchers built an analogue computer that uses water waves to forecast the chaotic future

Can a computer learn from the past and anticipate what will happen next, like a human? You might not be surprised to hear that some cutting-edge AI models could achieve this feat, but what about a computer that looks a little different—more like a tank of water?
