ARCHIMEDES BATHTUB HOW TO
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.Īrchimedes' insight led to the solution of a problem posed by Hiero of Syracuse, on how to assess the purity of an irregular golden votive crown he had given his goldsmith the pure gold to be used, and correctly suspected he had been cheated by the goldsmith removing gold and adding the same weight of silver. ) He then realized that the volume of irregular objects could be measured with precision, a previously intractable problem. (This relation is not what is known as Archimedes' principle-that deals with the upthrust experienced by a body immersed in a fluid. 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. The exclamation "Eureka!" is attributed to the ancient Greek scholar Archimedes. The initial /h/ is dropped in modern Greek and in several other European languages, including Catalan, French, Italian, Spanish, Portuguese, Dutch, and English, but preserved in others, such as Finnish, Danish, and German.ġ6th-century illustration of Archimedes in the bath, with Hiero's crown at bottom right The long vowels in the first two syllables would sound like a double stress to English ears (as in the phrase Maltese cat). In the Greek pronunciation, the first syllable has a high pitch accent, because the Ancient Greek rules of accent do not force accent to the penult unless the ultima (last syllable) has a long vowel. The accent of the English word is on the second syllable, following Latin rules of accent, which require that a penult (next-to-last syllable) must be accented if it contains a long vowel. It is closely related to heuristic, which refers to experience-based techniques for problem-solving, learning, and discovery. "Eureka" comes from the Ancient Greek word εὕρηκα heúrēka, meaning "I have found (it)", which is the first person singular perfect indicative active of the verb εὑρίσκω heurískō "I find".
