Eureka (word)
The exclamation 'Eureka!' is attributed to the ancient Greek scholar Archimedes. He reportedly proclaimed "Eureka! Eureka!" after he had stepped into a bath and noticed that the water level rose, whereupon he suddenly understood that the volume of water displaced must be equal to the volume of the part of his body he had submerged. (This relation is "not" what is known as Archimedes' principle—that deals with the "upthrust" experienced by a body immersed in a fluid.) He then realized that the volume of irregular objects could be measured with precision, a previously intractable problem. He is said to have been so eager to share his discovery that he leapt out of his bathtub and ran naked through the streets of Syracuse.
Eureka Spurs
The Eureka Spurs () are several rock spurs exposed along the east side of the head of Mariner Glacier, southwest of Mount McCarthy, in Victoria Land. They were so named, after the ancient Greek word eureka, by the Victoria University of Wellington Antarctic Expedition field party to Evans Neve, 1971–72, on the occasion of fossil discoveries made in the area.
