ARCHIMEDES

         Eureka! Famously shouted by this philosopher running naked and taking long bath after discovering the solution to Hieron crown. ''I have found it'' the meaning of from the Greek word Eureka. This man was born in 287 B.C and lived for 75 years which was extremely long lived for a person in those time. He was the son of an astronomer and mathematician Phidias. His family was some way related to that Hierio II the king of Syracuse. This philosopher, is also a greek mathematician, physicist, engineer, inventor, and astronomer. You want to know who this philosopher is? He is Archimedes. Archimedes is said to have been killed during the siege of Syracuse. (https://en.wikipedia.org/wiki/Archimedes)

        The king of the land wanted to wear a Golden Crown. He gave some gold to a goldsmith to make a suitable crown. After few days, the goldsmith brought the finished crown to the King. The crown was weighed. The weight of the crown was equal to the gold given to the goldsmith by the king. The king looked at the color of the crown. he had a suspicion. The goldsmith could have stolen some gold from the gold given to him. The king wanted to find out the truth. He asked his court scientist Archimedes to find out. The king said, ''Find out how much gold had been stolen?''

        How to find out the truth? Archimedes thought about the problem day and night. One day he was about to have his bath, but he was busy thinking. He did not notice the bathtub. Immediately a large quantity of water flowed over the brim of the bathtub. He noticed this suddenly. His brain wave worked suddenly. He jumped out of the bathtub, shouting, ''Eureka! Eureka!'' Uereka in Greek means '' I have found it'' (https://www.englishforstudents.com/Eureka-Eureka.html)

        In my analysis the meaning of Eureka is I have found, he discovered a method of detecting the amount of alloy mixed with the gold in the crown of the king of Syracuse. Archimedes had been considered he had found the law of Buoyancy at ''Eureka'' moment because it seems to have been considered that the overflow water volume measurement that vitravius wrote is impossible. It is true that Archimedes did not find the ''The Law Of Buoyancy Of Eureka'' moment at this moment he must found the solution of the king Hieros problem in specific gravity. 

Now do you want to say Eureka?
