Invented in the first century by Greek mathematician Hero of Alexandria, the Hero engine, or aeolipile, is a steam-powered device that illustrates the reactive forces of a gas jet. It usually consists of a mounted spherical vessel equipped with angled nozzles that release steam in opposite directions, causing rotational movement. The world’s first steam engine, Hero’s aeolipile was a forerunner of the modern jet engine. Its name derives from a term meaning “ball of Aeolus.” Who was Aeolus? Discuss
