What to Celebrate this Week: Pi (π) Day!

by Stefanie on March 13, 2010

When: March 14 (3.14) at 1:59pm

Pi = 3.1415926535…

Mmmmm, Pi.

The Greek letter π, is the symbol for the ratio of the circumference of a circle to its diameter. Wait, wake up! Come back! Pi Day is fun, I swear! You don’t have to be a math enthusiast to celebrate Pi Day! Perhaps you love something else round that goes by the same name?

A fairly new national holiday, The U.S. House of Representatives passed a non-binding resolution recognizing March 14, 2009 as National Pi Day. But self-proclaimed geeks have been exchanging “Hi-π‘s” on March 14th long before the day was nationally recognized. The first Pi Day celebration was held in a circular space at the San Francisco Exploratorium in 1988 where members of the staff and the public ate fruit pies. The founder of Pi Day, Larry Shaw (AKA The Prince of Pi) is a retired physicist at the Exploratorium and still helps out with the celebrations. But you don’t need a retired physicist to plan your Pi Party, you can do it with these simple ideas from PartyLand!

FOOD:
Whether it be pastry or pizza, strawberry or sausage, once a year on Pi Day we can celebrate pie too! For snacks set out ‘pi’neapple or ‘pi’ne nuts. And for dinner serve a chicken pot pie!

Don’t let this deliciously geeky holiday slip your friend’s mind. Send a Pi ecard!

MAKE A PI NECKLACE:

Make a Pi necklace to reinforce the idea that some numbers never repeat or end. Use from 100 to 300 beads, depending on the size of the bead. Assign a color to each digit (including 0) then string the beads into a necklace, using the digits of Pi as your color guide.

MUSIC:
Play American Pie or create your own Pi music here!

Then see how many digits of Pi you can memorize. The world record is held by Chao Lu who recited 67890 digits in 2005. This song will help get you started: Pi Song

F-Y-Pi: March 14th is also the birthday of Albert Einstein and the two events are sometimes celebrated together.

Q: What do you get when you cut a jack o’lantern by its diameter?
A: Pumpkin Pi!

Happy Pi Day everyone!
