I love pi (and pie), so I LOVE Pi Day. Still, I've talked about it before (most notably here - scroll down - and here), so I was thinking “been there, done that” –
Then I realized that THIS year, Pi Day wasn't just Pi Day—it's Pi Day of the Century!
You see, pi, which is the ratio between the circumference to the diameter of a circle, is an irrational number that goes on and on and on and on...
Pi starts 3.14... (and then goes on forever, never repeating itself), and so we celebrate Pi Day on 3/14 (March 14).
But today we get this:
3.141592653 = 3/14/15 at 9:26:53 in the morning!
So get ready to celebrate Pi Minute at 9:26 A.M. today, and Pi Second at the 53-second mark!
How do you get ready?
- Make a Pi Day of the Century shirt.
- Make (or buy) and eat some pie.
- Be ready to talk about the wonders of irrational numbers that go on forever!
- You can also join a Pi Day Facebook group!
Also, happy birthday, Akira Yoshizawa, grandmaster of origami!
Born in Japan on this date in 1911, Akira Yoshizawa is credited with raising origami from a craft to an art. He made more than 50,000 origami creations—and only a few hundred are explained with diagrams in his 18 books on origami. Most are unexplained, unique creations—although of course some people try and even succeed at copying them.

One thing I noticed about Yoshizawa's work is that much of it is very simple. I love complicated, detailed origami, such as Brian Chan's amazing insects. But there is something so beautiful and satisfying with some of these seemingly simple pieces.
