Hero of Alexandria: Mechanics, Steam, and Electric Dreams

The provided source offers an extensive overview of Hero of Alexandria, a pivotal Greek engineer and mathematician from the 1st century A.D., summarizing his life and numerous mechanical and mathematical contributions. Hero's key innovations are highlighted, including the development of the first steam-powered engine, the aeolipile, which is considered a precursor to the reaction turbine, along with his formula for calculating a triangle's area. The episode details his mechanical systems, such as the organization of five simple machines, the creation of measuring instruments like the dioptra, and theatrical automata which often combined science with illusion. Finally, the source presents a modern thought experiment, suggesting that Hero would have been fascinated by the concept of the electric car, viewing its silent, autonomous propulsion as the realization of his ideal "perpetual motion" machine, specifically identifying the VW ID. Buzz as a model he might have favored.
