(Unknown - Unknown)

Archimedes
Greek inventor and mathematician

Born in 287 BC in Syracuse, Sicily, he was educated in Alexandria (Egypt).
Archimedes was a cousin of King Hierón II of which was Counsellor and head of the defence of the city. The determination of King Hierón was the construction of a large fleet and built the Syrakosa, the largest ship of its time, that at the time of its launching was muddy. Archimedes using compound pulleys helped by levers shoring up in town got to raise it to float to the fascination of the King.
It is anticipated many of the discoveries of modern science, pure mathematics . He was able to show that the volume of a sphere is two-thirds of the volume of the cylinder that circumscribes it. In addition, in mechanics, he defined the law of the lever and is recognized as the inventor of the compound pulley. In Egypt he invented the 'worm' to raise the water level. Famous for the discovery of the law of hydrostatics, also called Archimedean principle, which States that any body immersed in a fluid experiences a loss of weight equal to the weight of the volume of the fluid that dislodges. It is said that this discovery did while he bathed, to see how water moved and was overflowed.
The greater part of the life of Archimedes took place in Sicily, Syracuse and surrounding areas, and dedicated it to the research and experiments. During the Roman conquest of Sicily was at the disposal of the authorities of the city and many of its mechanical instruments used in the defense of Syracuse. Between the war machine highlights their inventions of the Catapult and a system of mirrors that burned ships enemy to focus them with the rays of the Sun.
When Syracuse was conquered during the Second Punic War, it is believed that he was killed by a Roman soldier who found him drawing a mathematical diagram in the sand in 212 BC. They say that Archimedes was so involved in operations that offended the intruder by saying: "Not my diagrams disorders".
