Who was the coolest mathematician ever?

Could it have been Pythagoras, Archimedes, or Eratosthenes?

What were their claims to fame? How have they influenced our world through their discoveries or theories? Do they have a particular thing they are renowned for?

Pick your favourite and say why :-)

The basic shape is similar to the one pictured above. The dimensions and proportions are bigger.
