Etymology

The word 'buoyancy' originated from the Old French word 'buoiance', meaning 'to buoy up'. It has been used in English since the late 18th century. The concept of buoyancy in physics was first described by the ancient Greek mathematician Archimedes, who stated that an object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object.
