HERON OF ALEXANDRIA (ca. 75 AD)




I know this latest column is not about David Bowie, but if you are curious about history and mathematics, you would be surprised to discover (if you don't know already) what Heron of Alexandria invented.

Leonard De Vinci is his son in a way. Heron built a lot of machines especially for priests. There were a huge concurrence between religions in Egypt and every priest tried to find a solution to attract people 'cause they needed money.

Heron built doors who could be opened automatically, people were impressed and thought it was magical, but in reality it was a mechanism used by priests.
