The word "eureka" is often used to express excitement when someone has finally found the solution to a problem or made a new discovery. It comes from a story about a famous Greek scientist who shouted "eureka" when he discovered the solution to a problem he had been working on for a long time. Nowadays, people might say "eureka" when they suddenly figure out the answer to a math problem, or when they finally find their lost keys. It's a way of showing joy and enthusiasm for a breakthrough or revelation.
