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
March 14th (3/14) is celebrated as PI Day every year. Albert Einstein – one of history's greatest minds – was born on that very day in 1879. Coincidence?
