Archimedes: Greek mathematician, phycist, engineer, inventor, astronomer

The “eurika” guy.

A King had asked a goldsmith to create him a crown using the gold provided. After recieving the crown, the King had an inkling that the goldsmith had cheated by sneaking silver into the crown and had kept some of the gold to himself. That’s when the King had asked Archimedes to ‘investigate’.

One day when taking a bath, Archimedes noticed how much of the water was displaced depended on how much of his body was immersed.

Density = mass—volume

Archimedes was able to discover that the goldsmith did indeed sneak silver into the crown. Gold is more dense than silver.
