Archimedes is regarded as the greatest Greek mathematician. He invented 3 simple machines, the pulley, screw, and lever. The Archimedes screw, a device used for raising water, is still in use today. He also analyzed the area of a circle and discovered how to calculate volumes and surface areas of spheres and cylinders
