Eureka (Greek "I have found it") is an exclamation used as an interjection to celebrate a discovery.

It is most famously attributed to the ancient Greek scholar Archimedes; he reportedly said "eureka!" when he stepped into a bath and noticed the water level rise -- 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 meant that the volume of irregular objects could be calculated with precision, a previously intractable problem. He is said to have been so eager to share it that he leapt out of his bathtub and ran through the streets of Syracuse naked.
