“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”. It is closely related to heuristic, which refers to experience-based techniques for problem-solving, learning, and discovery.
Isn’t it latin for ‘fetch me my towel’?
