1. Archimedes developed the Archimedean screw, an invention designed for raising water for irrigation and drainage purposes.
2. He made significant contributions to the field of geometry, calculating areas and volumes of shapes, including spheres and cylinders.
3. Archimedes is credited with formulating the law of the lever, which describes how different weights can balance each other at varying distances from a fulcrum.
4. His work on hydrostatics led to the formulation of Archimedes' principle, which states that a body immersed in fluid experiences an upward force equal to the weight of the fluid it displaces.
5. Many of Archimedes' discoveries were recorded in works that were not fully appreciated until centuries later, influencing scientists during the Renaissance.
