Pretty much self expanatory.
Ill go with this dude.
ARCHIMEDES
Hard to believe most of his work was lost. Who knows where science would be today if this had not happened. Its even said that he was the first to invent the computer.
Archimedes was the eminent mathematician and excellent physicist of his time. He was born in Syracuse, on the island of Sicily in 287 B.C. At that time Sicily was a Greek land. Archimedes was the son of an astronomer. He studied at Alexandria in Egypt, and then returned to Syracuse. He early became an astronomer. He constructed a brass planisphere - a projection of the celestial sphere - that showed the revolution of the Sun, the Moon and the five known planets, and showed the nature of eclipses.
Discoveries and inventions
During a Roman siege of Syracuse in 213 Archimedes kept off the attacks of the Roman forces. There is a legend, that he used a gigantic mirror which focused the Sun's rays upon the Roman ships. When the Romans overcame the Syracusan defences, they ordered to bring Archimedes to Rome. Archimedes was 75 at that time. A Roman soldier was near Archimedes after the breach of the city's defence. Archimedes, probably tired after his work during the siege, was sitting on the ground, drawing mathematical figures in the dust. A soldier ordered him to surrender, but the great mathematician paid no attention to him. The problem was more important to him. Archimedes said, "Get away from my circles, you dog!" The soldier killed the world's greatest thinker.
His planisphere was taken to Rome and was described by Cicero, 150 years later. Archimedes is generally regarded as the greatest mathematician and scientist of antiquity and one of the three greatest mathematicians of all time.
