It's a number you never forget from school: 3.14, aka π aka the ratio of a circle's circumference to its diameter.

It's also the perfect excuse to bake and scarf down pies today, on Pi Day. Today has been dubbed Pi Day of the Century since at 9:26:53 AM it marked exactly 3.1415 9:2653.

Nerds rejoice with some cherry pie!

Never loved math more than now.


God bless America, and apple pi.

Crumble straight to my heart.


Ultimate nerdery.

In my belly!


Of course the pros jumped on the Pi bandwagon


A little burnt around the edges, gooey on the inside. Such a metaphor for life.


This is not a pie, it's straight-up chocolate cake. Pi Day don't care. Neither do I.

This, on the other hand….nice try.
