Mind power:
Hero was Greek or Hellenized Egyptian. He was a prolific writer, but many of his manuscripts and drawings have been lost over time.
Hero was a follower of the pioneering work of Ctesibius, the man believed to be the first head of the Alexandria Museum. Scholars assume that Hero also taught there.
The calculations known as Heron’s algorithm (for determining the square root of a number) and Heron’s formula (for finding the area of a triangle when the side lengths are known) came from the analytical mind of the ancient mathematician.
