Archimedes

Archimedes was born in the city of Syracuse on the island of Sicily in 287 BC. He was the son of an astronomer and mathematician named Phidias. Aside from that, very little is known about the early life of Archimedes or his family. Some maintain that he belonged to the nobility of Syracuse, and that his family was in some way related to that of Hiero II, King of Syracuse.

In the third century BC, Syracuse was a hub of commerce, art and science. As a youth in Syracuse Archimedes developed his natural curiosity and penchant for problem solving. When he had learned as much as he could from his teachers, Archimedes traveled to Egypt in order to study in Alexandria. Founded by Alexander the Great in 331 BC, Alexandria had, by Archimedes' time, earned a reputation for great learning and scholarship.

After his studies in Alexandria, Archimedes returned to Syracuse and pursued a life of thought and invention. Many apocryphal legends record how Archimedes endeared himself to King Hiero II, discovering solutions to problems that vexed the king.

One such story recounts how a perplexed King Hiero was unable to empty rainwater from the hull of one of his ships. The King called upon Archimedes for assistance. Archimedes’ solution was to create a machine consisting of a hollow tube containing a spiral that could be turned by a handle at one end. When the lower end of the tube was placed into the hull and the handle turned, water was carried up the tube and out of the boat. The Archimedes Screw is still used as a method of irrigation in developing countries.

Despite the many fantastic tales surrounding the life of Archimedes, we are most indebted to him for his mathematical treaties and the contributions he made to the understanding of fundamental physical phenomena. Through the medium of geometry, he was able to elucidate the principles for such basic devices as the pulley, the fulcrum and the lever – devices still utilized today. Archimedes is also credited with the discovery of the principle of buoyancy, or the power of fluid to exert an upward force on a body placed in it. His further research into volume and density was fundamental to the development of theories of hydrostatic – the brunch of physics dealing with liquids at rest.
