Today is Pi Day. March 14th… 3/14… 3.14… get it?


We’re a little on the geeky side here at Zazzle and couldn’t help but notice that today is a special day for one of our favorite mathematical constants in the world – Pi!

Some interesting facts about Pi that I found on Wikipedia:

  • The symbol for Pi is the first letter of the Greek word that means “circumference”
  • Pi has been calculated to over 1 trillion digits with supercomputers and no pattern has yet been discovered
  • The current world record for digits of Pi memorized is 100,000 decimal places which was set on October 3, 2006 by Akira Haraguchi. It took him 16 hours to finish!

The internal Zazzle record for digits of Pi memorized is 32 decimal places by one of our head backend engineers Jason Li. Not too shabby even though he says his feat is way too lame compared to what Akira memorized.

Think you can do better than Jason? Leave a comment telling us how many digits you can do. It’ll be even better if you can link to a video of you performing your amazing feat. As an added incentive, we’ll send the winner a Pi inspired product from Zazzle like the ones below:
