March 14

It comes every year on this day.  March 14.  It’s better known as Pi Day.

I can remember first learning about Pi.  3.14 or 22/7 was good enough to solve the problems presented in class.  And, beyond that, why would you want to learn more?

Then, I had a real mathematics geek who got us more excited and encouraged us to learn more about Pi and to memorize more than just two digits of decimal places.  So, I went as far as 3.1415926.

The game changed with the calculator and this magic button.

And, of course, your favourite programming language has a value of pi built into it.  Have you ever wondered to how many digits of accuracy?

The worlds best URL is located at “http://3.141592653589793238462643383279502884197169399375105820974944592.com/

The website is called Pi to 1,000,000 places.  Visiting and actually finding the million digits are two different things but hey…

Or, cheat and visit this site.

And get a poster here.

Or, write your own program.

I’ve been keeping track of interesting things about Pi for a long time.  The current collection is here.  I supposed collecting links for this is irrational but it keeps me occupied and I enjoy solving the challenges and read that there are so many mathematicians fascinated by documenting their experiences.

It’s a shame that Pi Day appears during the March Break.  But, you could always celebrate when the students come back or, get ahead of the game, like Alice Aspinall did.

The content of this blog is created by me at the keyboard or as a result of an aggregator of my daily reading under the title OTR Links. On Fridays, look for my signature post "This Week in Ontario Edublogs" where I try to share some great writing from Ontario Educators. The other regular post appears Sunday mornings as I try to start a conversation about things that have gone missing from our daily lives.

  1. Agh. I’m asleep on the job. Now scrambling to figure out what I can quickly make today to celebrate pi day. Last year, we had mini quiches for breakfast, tarts for dessert, and a meat pie for supper.
