ARCHIMEDES (287-212 BC.)

Archimedes was the first scientist to use the power of the lever. This gifted Greek

mathematician and inventor once said, "Give me a place to stand and rest my lever on, and

I can move the Earth." He also discovered the compound pulley and Archimedes'screw.

Archimedes was a brilliant mathematician who helped develop geometry. He discovered

the relation between the surface area and volume of a sphere and those of its

circumscribing cylinder.

A legend says that Archimedes discovered the principle of displacement while

stepping into a full bath. He realized that the water that ran over equaled in volume the

part of his body that was in the water. Through more experiments, he presumed the

principle of ability to float, which is called the Archimedes' principle. According to this

principle a body dipped in a fluid loses as much in weight as the weight of an equal volume

of the fluid.

Another legend describes how Archimedes uncovered a fraud against King Hieron

II of Syracuse using his idea of flotation. The king suspected that a solid gold crown he

ordered was partly made of silver. Archimedes first took two equal weights of gold and

silver and compared their weights when put in water. Next he compared the weights of the

crown and a pure silver crown of identical dimensions when each was put in water. The

difference bet...
