Archimedes Streaking Around

Archimedes was a Greek mathematician who lived in the third century B.C. I know this is supposed to be about scientists and not mathematicians, but back then, Archimedes was as close to a scientist as you could get. 

Needing some relaxation, he decided to bathe at the public baths. As he stepped into the full tub and saw the water overflow, he realized that the volume of his body that was submerged was equal to the volume of water that overflowed. He had his answer for measuring the volume of the crown. He got so excited that he ran home naked through the streets, yelling Eureka, eureka G ve found it ) And this method of determining the volume of an irregular solid is still used today. (By the way, the crown was an alloy, and the dishonest jeweler received swift justice.)
