||Many people will already be familiar with some of the inventions of
the ancient times, so we'll focus on something a little different.
Over the years irrigation has been an important and well developed field of
science because of its importance to crop growth. Well, you may have heard of an ancient
Greek inventor called Archimedes. Archimedes was an inventor as well as a discoverer and a
physicist. One of his most important inventions was the Archimedes screw, which draws up
water. It is still in use today as a primitive water pump, but it is also used in many
hydroelectric power stations to draw up huge volumes of water! The archimedes screw works
by a rotating spiral of wood or metal inside a tube. When the spiral is turned water is
drawn up the tube.
