Happy Pi Day!

PiIt’s here! March 14. It’s Pi Day.

(Get it? The date is 314.)

I talked a little bit about it in this Pi post last year.

For the uninitiated:

The Greek letter Pi is the symbol for the ratio of the circumference of a circle to its diameter. It’s celebrated on March 14, (3/14) because the first few digits of Pi are 3.14. Pi is unique because it’s the only fraction which does not repeat.

The folks over at Pi have links to Pi’s first million digits. Very cool.

Three years in a row, the blog 360 (a very cool math blog) posted a Pi Sudoku. Not this year. But here are links to previous pages:

Pi Sudoku 2008
Pi Sudoku 2009
Pi Sudoku 2010

Check out this link:

(It doesn’t link to any really nifty math stuff, unfortunately, but the URL is still pretty kewl, no?)

And here’s a wonderful page called the Joy of Pi which has tons of very fun Pi links.

I’m off to read about Pi and the Fibonnaci Numbers.

Happy Pi Day!

p.s. Today is also Albert Einstein’s birthday…he didn’t discover Pi, but he’s geeky coolness unto himself.

  • Thanks for the kind words about 360! I wanted to give you a heads up that there’s also a 2011 sudoku (variation) puzzle. I just posted about it here, but it comes from Brainfreeze Puzzles.

    • Oh, hi! Thanks for stopping by to say hello, and for the link to the 2011 Pi Sudoku puzzle, and for setting me straight that it’s a Brainfreeze Puzzle and not a 360 puzzle from the awesome folks in the Nazareth College Math Department. Even if you don’t write the puzzles, you guys rock. 360 is one of my favorite math blogs…because you talk about really kewl math stuff. Happy Pi Day!
