Did you know that today is Pi Day? ( I know, I know, I'm weird like that!) Pi represents the ratio of a circle's circumference to its diameter.
$\pi = \frac{C}{d}.$
This ratio, Pi, is an irrational number meaning it will continue infinitely without ever repeating and thanks to computers, we now know the value of Pi to over 1 trillion digits!

Happy Pi Day all!
