Do you know that Archimedes' principle was invented during bath? 🛀

Today, I am going to tell you an interesting story about how the Archimedes' principle was invented, who invented it, and why. If you don't know what Archimedes' principle is, when you submerge a body (object) in the water, then there will be a force that will push it upwards called buoyant force. This force will be equal to the weight of the fluid (water) that is displaced by the body. This is called Archimedes' principle.

I was scrolling through youTube and suddenly I came across this interesting video in which they explain how the Archimedes' principle was invented while taking a bath.

So the story goes like this: One day, the king of Sicily summoned a goldsmith to make a crown for himself. The King gave him the exact amount of gold that was needed to make the crown. After some days, when the crown was completed, the goldsmith gave the gold crown to the king. But the king suspected that the goldsmith had cheated him. The king thought that the goldsmith kept some gold for himself and added silver to make the crown so that no one would suspect him. So, the King summoned Archimedes and ordered him to find out whether the goldsmith really cheated him or not, but on the condition that Archimedes couldn't harm the crown in any way. 

So Archimedes begins to think about how he will find out if the goldsmith really cheated the king or not. He thought hard but couldn't come up with an answer to the king's question. But one day, he was going to take a bath, and the bathtub was filled to the brim. He noticed that when he sat down in the bathtub, the water level rose and water overflowed from the bathtub. He realised that something was happening here. After some more experiments, he realised that how much water spilled out of the bathtub depended on how much of his body was immersed. This led to the discovery of the Archimedes' principle.

After this discovery, Archimedes went to the king, and then he placed the crown in a water jar, and in another water jar he placed the amount of gold that the king gave to the goldsmith to make the crown. Because the density of gold is greater than the density of silver, he just needed to measure the density of the crown and compare it with the density of the total gold given by the king. But the crown has an irregular shape, so how can we measure its density?

Here, Archimedes' principle comes into play. That is why he submerged the crown and gold in water jars. With this method, he found the volume of gold and the crown. With their volume, he found their respective densities. Because the crown was less dense than the gold, the king found out that the goldsmith had indeed cheated him.
