quiz : technology : WHAT NATIONALITY WAS THE SCIENTIST WHO INVENTED THE STEAM ENGINE? [+] ballot by texsue57 ACTIVE Thu Apr 06, 06 - Tue Dec 30, 08 Heronas’ Steam Engine "Heronas of Alexandria was a Greek mathematician, engineer and inventor of the first century BC. He initially worked as shoemaker but he eventually decided to explore his ideas. He is better known as an engineer for his hydraulic mechanisms, simple machines and automations, but he was also an important mathematician of his time. He served as a director of the famous Technical School of Alexandria (maybe the world’s first polytechnic university). He presented and operated the world’s first steam engine, consisted of a closed, spherical container, filled with water. When the water was heated and began to boil, the stream was relieved by two nozzles, configured in a polar alignment. The container was fixed in such a way that was allowed to rotate. The steam release caused a rotating motion of the container that could be used as a steam motor for various applications. The principle of this simple configuration is the same used today for jet propulsion." I thought I'd bring a little known fact to light.
