Archimedes

Definition

Archimedes was a Greek mathematician, physicist, engineer, astronomer, and inventor who lived during the Hellenistic period. He is best known for his contributions to mathematics, particularly in geometry and the understanding of the principles of buoyancy and levers. His work significantly influenced the development of science and engineering, making him one of the most important figures in Hellenistic thought.
