Heron, also known as Heron of Alexandria (? ρ ω ν λ ε ξ α ν δ ρ ε), an ancient Roman mathematician, lived in Alexandria, a Roman province.

He is also an engineer, active in his hometown of Alexandria. He invented a steam engine called a spinning ball. He also invented the wind wheel, which was the earliest equipment to use wind energy. He is generally regarded as an atomist. Some of his ideas come from the works of Cortexibius.

background introduction

The arithmetic and algebraic geometry of ancient Babylonian civilization have always had a great influence on ancient pan-Mediterranean civilization. Because Herod's works were deeply influenced by Babylonian culture, he was once considered as an ancient Egyptian or Phoenician by scholars, but some scholars thought he was a Greek.

C. B. Boyer, a mathematical historian, explained that Herod was considered an ancient Egyptian or a Phoenician because his works had a strong Babylonian color.

action

Because most of Hiro's works (including mathematics, mechanics, physics and gas mechanics) appear in the form of lectures, he is considered to have taught in the Muse House (including the Alexandria Library).

In addition, although these academic fields were not formalized before the twentieth century, his inventions were all research materials of model control. Hong invented many devices, such as spinning ball, vending machine, syringe, steam organ and so on.
