Eureka, from a Greek word for I have found. Archimedes ran down the street yelling out Eureka in excitement that he has realized the solution to his problem of how to confirm a gold crown's purity. I wonder if I can ever be completely obsessed with something with passion to a point where I would forget my current physical state (e.g. Archimedes forgetting he was naked 'cause he was in the middle of taking a bath). Do you have a passion like that?
