Heron's steam engine

<space=1em><b>Heron of Alexandria</b>

<space=1em>Heron lived in Alexandria, Egypt, around the first century AD. He taught at the <nobr>Museion of Alexandria,</nobr> the scientific center of ancient Egypt, which included the famous library.

<space=1em>Heron's most famous work is "Metrica", which gives definitions of a spherical segment, a torus, as well as rules and formulas for the exact and approximate calculation of the areas of regular polygons, the volumes of truncated cones and pyramids. His "Mechanics" is also an outstanding scientific work.

<space=1em>Heron's "Pneumatics" can also be considered one of his most significant works. A significant part of it is a description of various siphons and vessels from which water flows by gravity through a tube. The book mentions about <nobr>80 devices</nobr> and mechanisms operating using the principles of pneumatics and hydraulics, including the famous aeolipile and a water pump that was unique for its time. The originals of these works have not survived. Only rewritten copies of Heron's works made by his students and followers have survived to this day.

<space=1em><b>Aeolipile</b>

<space=1em>Heron was the first to create a prototype of a steam engine, suggesting that a mechanical shaft could be made to rotate using heat. The operating principle of his aeolipile ("the ball of the god of winds Aeolus" in Greek), the drawings of which have survived to this day, is well known.

<space=1em>The aeolipile was a tightly sealed boiler with two tubes on the lid. A rotating hollow ball was installed on the tubes, on the surface of which there were two <nobr>L-shaped</nobr> nozzles. Water was poured into the boiler through a hole, the hole was closed with a plug, and the boiler was placed over the fire.

<space=1em>When the boiler was heated, the resulting steam entered the ball through hollow tubes and escaped through nozzles. The reactive force of the steam jets created a torque, causing the ball to rotate around its axis.
