Is there something you love so much that you could spend hours doing it? Maybe you love video games, reading or watching movies. Archimedes was an ancient mathematician who lived 200 years before Christ’s birth. He loved math so much that sometimes he forgot to eat while he was figuring problems.

Archimedes is considered to be one of the most brilliant mathematicians in history. He figured out many complicated mathematical equations. He probably got his love for math from his father, who was an astronomer. Archimedes invented a miniature planetarium, but his main job was to solve problems for the King of Syracuse, which was a part of Sicily in Italy.

Legend has it that the king worried that the royal crown maker might be replacing some of the gold in his crowns with a less valuable material. The king asked Archimedes to find a way to determine if the crowns were 100 percent gold. Archimedes thought of the solution while in his bathtub. He supposedly jumped out of the tub and ran through the streets naked, shouting, “Eureka! Eureka!”

Some tales say he invented giant mirrors that could light the sails of war ships on fire through the heat of the sun.
• Archimedes did figures wherever he was. He often worked on problems in the dirt, using a stick as a pencil.
• The Romans eventually succeeded in invading Syracuse. Archimedes was slain by a Roman soldier.
