Pi Day

A day to celebrate the mathematical constant π (pi). While it might seem like a niche interest for mathematicians, Pi Day has become a global celebration of curiosity, problem-solving, and the sheer elegance of the universe. This lesson explores why humans are so obsessed with finding patterns, whether math is a language or a discovery, and how a simple number can inspire a worldwide celebration.

  7. If you were to discover a new universal constant today, what would you name it and what would it represent?
