Pi Day

PiDayToday is March 14, which means it’s Pi Day!

Pi, of as you might know it: π, is a mathematical symbol used to represent the ratio of a circle’s circumference ( length of the outside of the circle) compared to it’s diameter(the length of the inside of the circle). It’s always the same no matter the size of the circle and it is usually written out as 3.14. However, this isn’t a true representation of pi.

Pi is an infinite number. Mathematicians are still calculating pi to try and find an end to the numbers behind the decimal. So far, over one trillion digits have been calculated and there’s no clear sign of stopping. In fact, there will never be a clear sign of stopping.

Math lovers around the world have designated March 14 (3/14) as international pi day. They celebrate by holding contests to see who can memorize the most digits of pi, baking pies to eat, baking cakes in the shape of pi (but it’s pi, but it’s cake, but it’s pi, but it’s cake!), and noticing pi in every day life.

Here’s a song that might help you memorize pi if you’re so incline. At least, the first few digits.
