Archimedes was the best mathematician and inventor of the ancient world. King Hiero asked Archimedes to design a pump to drain his ship during the voyage to Alexandria, Egypt. Archimedes devised a simple but brilliant solution. The device today known as the Archimedes Screw. The screw lifts water when it turns, and was so effective that it was quickly adopted in many countries for irrigation. Some researchers have postulated this as being the device used to irrigate the Hanging Gardens of Babylon.
