What exactly is PI?
The shortest answer to one of the universe's greatest mysteries
3,141592653 … forever …
Every digit is unique – they NEVER repeat and never end
The circle's best friend
Draw a circle. Measure around the edge (circumference) and divide by the width (diameter). The answer is ALWAYS 3.14159… = PI! Try it with a pizza base! 😄
The universe in one number
With just 39 decimal places of PI you can calculate a circle as large as the OBSERVABLE UNIVERSE – accurate to a single hydrogen atom. 🤯
Infinite and irregular
PI is an "irrational number" – it can NEVER be written as a fraction. The digits are random with no pattern, forever. Nobody knows why! 🤷
PI Day = Einstein's birthday
