1949 – Moniac: A Hydromechanical Machine to Teach Economics

The MONIAC or Phillips machine is a hydromechanical analog computer built to teach basic economical principles using colored water flowing in transparent pipes. The machine was built in 1951 after electrical-engineer-turned-economist William Phillips and his economist colleague Walter Newlyn realized that flows were used as a metaphor to teach economics, but have never been made physical. Phillips is also known for his eponymous curves. Several MONIACs were built, and a working one is permanently displayed at the Economics Department of Cambridge University.

1949 – Mississippi River Basin Model

As a response to devastating floods of the Mississippi river in the early 1900s, the US Army Corps of Engineers built a large-scale hydraulic model of the entire river system. The model, 2.5 times the size of Disneyland, allowed them to design better flood control infrastructures and to eventually save millions of dollars. In 1973, the physical model ceased to be used and was replaced by computer models. Nevertheless, mathematical equations […]
