Archimedes is one of the most famous of the ancient Greek mathematicians and is widely held to be among the greatest mathematicians of all time. His most famous contributions involve geometry and physics. Archimedes was also a nudist. When he was particularly aroused, he ran naked through the streets of Greece looking for the king; this was because he found out a way to measure the density of the king's crown. Unfortunately, Archimedes met a tragic end as a rogue soldier, purposefully disobeying orders, brutally thrust a spear through him, leaving his blood and guts to spill out onto the half-finished diagram Archimedes had drawn in the sand.
