Archimedes was the man who ran down the streets of Syracuse shouting “Eureka!”, meaning “I have it!” in Greek. So, how does this matter? Well, he ran all naked on the streets. Oh! But why? For, it was no normal day in the history of science.
When the king of the land wanted a golden crown for himself, he gave some gold to a goldsmith and ordered him to make a crown. But, when the crown was made, the king was suspicious if the crown was made of pure gold or not. So, he asked his court scientist Archimedes to find out.
Archimedes was a Greek scientist. He lived in Syracuse nearly 2,000 years ago. He pondered over the king’s issue for quite some time. One day, when he was in his bathtub, he slid inside the tub. Immediately, a large quantity of water flowed over the brim of the tub. When Archimedes noticed this, his brain got into action. He jumped out of the bathtub, shouting, “Eureka! Eureka!”
Different metals of the same weight have different volumes. Objects, put in water, will displace water. The displaced water will be equal to their volume. For example, an iron cube weighing a kilogram will disperse some water. But an aluminum cube of the same weight will displace more water than the iron cube.
Archimedes tested the same and found out that the crown was not made of pure gold. He reported to the king, who then demanded the truth from the goldsmith. The goldsmith confessed to stealing the king’s gold.
Observe the world around you carefully and you can discover your own “Eureka moment”!
