Which greek mathematician ran through the streets of Syracuse naked while shouting "Eureka" after discovering the principle of displacement?

Archimedes, the famous Greek mathematician, ran through the streets of Syracuse naked while shouting "Eureka" after discovering the principle of displacement. This incident occurred when he realized that the volume of an irregularly shaped object could be determined by measuring the amount of water it displaced when immersed in a container. Overjoyed by this breakthrough, Archimedes could not contain his excitement and rushed through the streets proclaiming his discovery. This event has come to symbolize the enthusiasm and passion with which great scientific discoveries are made.
