Article excerpt

From a parlor trick in ancient Alexandria to the driving force of industrial revolution, the steam engine's journey spans nearly two millennia. Hero of Alexandria devised a simple device that spun when heated, a curiosity that seemed to have no practical purpose.

The progression from novelty to necessity reveals how technological breakthroughs often require both conceptual innovation and historical timing.
