"[Archimedes] happened to go to the bath, and on getting into a tub observed that the more his body sank into it the more water ran out over the tub. As this pointed out the way to explain the case in question, he jumped out of the tub and rushed home naked, crying with a loud voice that he had found what he was seeking; for he as he ran he shouted repeatedly in Greek, "Eureka, eureka." meaning "I have found (it), I have found (it)."
-Marcus Vitruvius Pollio
