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 […]

2015 – Solid Model of Stellar Winds

Scientists keep using solid models to help them better understand complex 3D data (here, an astrophysical simulation): They say this provides even more insight into what’s going on. “The ability to hold and inspect the 3-D printed models provides a new perspective on the WWIR’s geometry and an improved sense of the scale of the different structures,” they say. In particular, they say the model allows them to appreciate just how large the shockwave is compared to the stars and the distance […]
