Archimedes was a Greek mathematician who lived between about 287 and 212BC. Unlike many Greek philosophers of the time, Archimedes believed in making experiments to prove that his theories worked. He made practical inventions, such as the Archimedean screw which is still used today to lift water for irrigation. He also worked out the laws which govern the use of levers and pulleys.
Archimedes is most famous for allegedly leaping out of his bath in excitement shouting ‘Eureka!’ (The Greek for ‘I have found it!’). He did this when he realized that his body displaced a volume of water equal to its own volume.
