As always, Pi Day is March 14. While you can (and should) certainly celebrate the big day by eating as much pie as humanly possible, there's also another fun, and albeit nerdy, way to to celebrate — by memorizing the first 100 digits of pi.
But first, let's define pi. Pi is the ratio of a circle's circumference to its diameter. So, draw a circle with a diameter all the way across. The circumference all the way around the circle is pi.
Okay, now back to you memorizing pi's first 100 numbers. Here they are:
3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679
If musical numbers are more your thing (get it... musical... numbers), you're in luck. There's an adorable song and video on YouTube by AsapSCIENCE that will help you memorize pi's first 100 numbers.
Do it. You have until Sunday. Or until forever, because pi isn't going anywhere.
