The greatest mathematician of antiquity, a man of superlative inventive power, well skilled in all the mechanical arts and sciences of the day. When Syracuse was taken by the Romans, he was unconscious of the fact, and slain, while busy on some problem, by a Roman soldier, notwithstanding the order of the Roman general that his life should be spared. He is credited with the boast: "Give me a fulcrum, and I will move the world." He discovered how to determine the specific weight of bodies while he was taking a bath, and was so excited over the discovery that, it is said, he darted off stark naked on the instant through the streets, shouting "Eureka! Eureka! I have found it! I have found it!" (287-212 B.C.).
