Archimedes of Syracuse was a Greek mathematician, physicist, engineer, inventor, and astronomer. He is known for coining the term “Eureka !” which means “I found out” when he was given a challenge to find out if the King’s crown is made of pure gold or had silver mixed up in it. This can be found by measuring the density of the crown and seeing if it matches the density of pure gold. But to find out the density, you need mass and volume. Finding the volume of the crown was hard since it is not a regular shaped object like a cube or sphere for which you can find out the volume by measuring its dimensions. Let’s listen to the full story of what happened and how Archimedes came up with a brilliant and yet simple idea to figure out the volume of irregular shaped objects when he was taking a bath ! • This is part 1 of the a 2 part Archimedes principle series. In this video we will do a quick DIY experiment to find out the volume of a golf ball ( a regular shaped sphere) by immersing it in water ( the Archimedes approach) and using its dimensions and see if they match ! • • Related videos: • Why things sink and float in water: • Density for kids Part 1: Why things s... • How heat affects density: Hot water/cold water experiment: • Density for kids Part 2: Hot and cold...
