Who Was Archimedes?

Legend has it that this Greek mathematician ran naked through the streets of Sicily shouting "Eureaka" when he discovered the buoyancy principle that bears his name.

But his contributions don't stop there. Investigate the inventor and scientist who calculated the value of pi, created an engineering device still used today, and much more — all some 2,000+ years ago.
