History

Etymology

From Ancient Greek εὕρηκα (heúrēka, “I have found”), perfect active indicative first person singular of εὑρίσκω (heurískō, “to find”). Archimedes supposedly exclaimed this when he figured out how to determine the density of an object. First use appears c. 1603 in a text by Philemon Holland.
