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” –
BUT!
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.
