ARCHIMEDES 287 B.C.-212 B.C.
The greatest mathematician of ancient Greece, and perhaps of all time, Archimedes perfected a method for calculating the areas and volumes of curved figures, deduced the approximate value of pi, devised the first general theory of levers ("Give me a firm place to stand on and I will move the Earth."), invented the water-screw and solved the dilemma of relative density while reportedly soaking in his bathtub.
In 212 B.C., Romans invaded the Greek city-state of Syracuse, home to Archimedes. Reports vary about what exactly happened, but the most common account describes a Roman soldier coming upon Archimedes drawing geometric symbols in the sand. The soldier demanded Archimedes cease and follow him. Intent upon his work, Archimedes refused. The soldier killed him.
"Do not disturb my circles," Archimedes reportedly cried with his last breath.
