If you’ve looked at the calendar today you’ve might noticed that today is Pi Day. 14 march (3/14) is a holiday of mathematical constant pi (pi symbol is greek letter π). If you don’t know what is pi, you better get back to school. Even miserable Wikipedia knows that pi is mathematical constant whose value is the ratio of circle’s circumference to its diameter. Who could have thought that over 12 000 people monthly is searching “what is pi” at Google. Btw Uncle G has terribly failed as he didn’t make any Google Doodle for this great occasion. Shame on you Google – you better don’t miss it next year if you still want to be recognized as geeky company.

But let’s leave Google and proceed to our beloved one. The Pi.

The hero of the day - Pi

If you are true geek, you should put this picture instead of your girlfriend / boyfriend photo in your wallet / purse. However if you are not that radical mathematician you can just go out and get drunk or something. Remember to sing the pi song until you lose conscious to proper celebrate Pi Day.

Pi song

They are still singing this song. If you want lyrics (which basically are digits of pi) to sing with them here you have first 100 digits of pi:

When celebrating and eating Pi pie you can amuse your friends with some pi day jokes which you will find below.

The mathematician says: “pi r squared.”
The baker replies: “No! Pies are round, cakes are square!”

Q: What do you call what happens when you cut a jack’o'lantern by its diameter?
A: Pumpkin Pi!

Uh, right they are not very funny… So maybe rather you should exchange with them some pi facts like, for example, that in Star Trek episode Wolf in the Fold Spock has neutralized an evil computer by ordering it to compute to the last digit the value of pi. Then you can watch Pi movie by Darren Aronofsky and finally try to fall asleep counting pi digits instead of sheeps.
