The Archimedes Spiral
Each year the Nile had floods and when the waters returned to normal, farmers plowed their fields and planted. The sun was so hot and the Nile valley so fertile that farmers got two or three crops a year.
But water was a problem. For months, there was no rain and farmers had to manually carry the necessary water, bucket by bucket, from the river to their fields.
Archimedes watched for a long time what they were doing, and thought that there must be a better way to do this work. He made plans and diagrams. He sought out a carpenter and explained what he wanted. The carpenter shook his head, having never seen anything like it, but he executed Archimedes' plan.
What he built was called the “Archimedes Spiral,” and it worked something like this: a wooden spiral, similar to a corkscrew, fitted into a cylindrical-shaped case. The end of the spiral was placed in water and the top was on the earth. There was a crank at the top of the instrument that, when activated, made the spiral rotate. While being held in the water at the proper angle, as it turned, it lifted the water, which passed successively from one spiral to the other, rising. Thus, the water of the Nile flowed over the land, in the fields.
More than two thousand years later, farmers in Egypt still use this instrument to irrigate their fields.
