The Famous mathematician Archimedes discovered the number 3.1415926535 897932384626433 was approximately closer to 3, than 4. Inspired by this insight he looked into finding a use for this fantastic number, and after many late nights spent pacing around his perfectly circular house; He found the number was also approximately equal to how much longer it took him to run around his house, than to run directly across it. Thus Archimedes is thought by all famous mathematicians of the modern day to be the first ever human being to own a perfectly circular house.
