ARCHIMEDES PRINCIPLE

The principle states “a body fully or partially immersed in a fluid is buoyed up by a force equal to the weight of the fluid that body displaces.”  There is an interesting legend that accompanies this principle.  Apparently Archimedes was asked by his close friend/relative King Hiero II whether a wreath (often falsely stated to be a crown) he received was pure gold or alloyed with another metal like silver as he suspected.  He could not destroy the wreath to make the determination.  Archimedes didn’t come up with a solution until one day while he was sitting in the bath.  He suddenly realized that since gold is more dense than silver, a given weight of gold will have less volume than an equal weight of silver.  Consequently, the gold would displace less water than an equal sample of silver.  Upon conducting the experiment, he found that a sample of gold equal to the weight of the wreath displaced significantly less water than the wreath.  This insight led to Archimedes Principle.
