was aGreek mathematician who flourished in Sicily. He is generally
considered to be the greatest mathematician of ancient times.
Legend has it that Archimedes discovered his principle of buoyancy,
which states that the buoyancy force is equal to the weight of
the liquid displaced, while taking a bath, upon which he is supposed
to have run naked through the streets of Syracuse shouting "Eureka!"
Archimedes' principle of buoyancy states that the buoyant force
exerted on a floating body is equal to the weight of the volume
of water which isdisplaced by that body. Since the weight of
water is about 62 pounds per cubic foot, huge forces result from
large displacements, so it becomes understandable how steel ships
float. This law or principle is used in determining specific
gravity of various substances.
