Archimedes did a tremendous amount of ground-breaking work on levers and pulleys, enabling the Greeks to move heavier things than ever before. He once bragged “give me a place to stand on, and I will move the earth”. He also invented the Archimedes screw, a device (consisting of a large screw inside a pipe) still used in irrigation today. Despite all this he considered his greatest accomplishment to be his book on the sphere and the cylinder. He even had a sphere and cylinder engraved on his tombstone when he died.
