Name the ancient Greek mathematician famed for the buoyant force principle and the story of weighing a crown with water displacement.

• A. Euclid
• B. Archimedes
• C. Pythagoras
• D. Aristotle

Answer: (B)

Buoyancy and using water displacement to detect density differences are what this is about. Archimedes is the ancient Greek mathematician famous for the buoyant force principle and the story of weighing a crown with water displacement. He argued that an object submerged in a fluid experiences an upward force equal to the weight of the fluid it pushes aside. That idea explains why objects float or sink and provides a method to test density by displacement. In the crown anecdote, he sought to determine whether the crown was pure gold by comparing its weight in air to its apparent weight in water, using the change caused by the displaced water to infer density. The other figures listed are known for geometry, theorems, or philosophy, but Archimedes is the one tied to this buoyancy principle and the displacement story.
