The Archimedes screw is a simple machine used to lift water from a lower level to a higher one. It consists of a helical screw inside a hollow tube. When the screw is turned, water is trapped in the screw's grooves and is lifted as the screw rotates. This device is often used in irrigation and drainage systems. Named after the ancient Greek mathematician Archimedes, the screw has been in use for centuries. It is efficient and can move large volumes of water with minimal effort. The design has inspired various modern applications in engineering and technology.
