Archimedes' principle. Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid. Archimedes' principle is a law of physics fundamental to fluid mechanics. It was formulated by Archimedes of Syracuse.
Archimedes was also an accomplished engineer and an inventor. He was believed to have been obsessed with Geometry though. Archimedes was born in Syracuse, Greece in 287 BC and died 212 BC after being killed by a Roman soldier who did not know who Archimedes was.rchimedes was also an accomplished engineer and an inventor.
