Happy Pi Day.
It's March 14 -- or 3/14 if you write down the date in the m/d format. And that means it's time to celebrate that mysterious mathematical relationship between a circle's diameter and its circumference: 3.1415926535...
Today is also, appropriately enough, Albert Einstein's birthday. So the science-minded among us have two good reasons to celebrate. He was born in 1879 and died in 1955.
But back to Pi. Two years ago, NPR's Bryant Park Project noted Pi Day with this report. As they said, Pi Day is when "numbers geeks all over the world bake pies, write 'pi-kus' and recite pi to as many decimal points as possible."
A "pi-ku", bu the way, works like this:
-- First line: 3 syllables
-- Second line: 1 syllable
-- Third line: 4 syllables
Not good at math
I'm sure many of you can do much better, feel free to add your own in the comments thread.
If you need inspiration, the folks at PiDay.org have lots of stuff to play around with, including links to Pi-related videos. Here's one:
