Archimedes Archimedes was a Greek mathematician, physicist, engineer, inventor, astronomer, and geometer. He is considered one of the greatest scientists of all time. Archimedes discovered the law of floatation while taking a bath. He noticed that the water level rose when he got into the bath, and he realized that this was because the water was displaced by his body. He then realized that this principle could be used to determine the density of objects. The law of floatation states that a body immersed in a fluid experiences an upthrust equal to the weight of the fluid displaced. This means that if the weight of the object is greater than the weight of the fluid displaced, the object will sink. If the weight of the object is less than the weight of the fluid displaced, the object will float. The law of floatation is used in many different applications, including the design of ships, submarines, and hot air balloons. It is also used in the construction of dams and other structures that must withstand the force of water.
