# Care for a slice of π?

Posted by & filed under Blog.

Today you have a few options. You can treat it as any typical day, or you can treat yourself and celebrate National Pi Day!

Yes, that’s right, National Pi Day.

If you’re unprepared or unsure of how to celebrate this mathematical wonder, we’ve got some suggestions.

First… what is pi? Unfortunately, it’s not the dessert. It is actually the numerical constant that is the ratio of the circumference to the diameter of a circle represented by the Greek symbol (π). Basically, it’s a super cool number that goes on forever but is often approximated in short as 3.14.

Get it? That’s why we celebrate it today. 3/14. Love it.

We’ve all probably encountered pi multiple times in our lives in one math class or another. It even has its own special key on calculators.  Pi can be used to solve so many equations, whether we want to solve them or not, and help make the world a better place.

So you’re probably wondering how you can celebrate pi, right? Right. Here are those ideas I mentioned.

1. Celebrate pi with pie! Have a pi(e) party, if you will. That’s what we did here in the Admissions Office at UW Oshkosh. You can even go all out and decorate your pies with pi symbols.
2. Go to a store and buy something priced at \$2.99. With tax, your total will be \$3.14.
3. Tell your friends (or math teacher) a pi joke. Here are a few to try out:
What do you get when you cut a jack-o-lantern by its diameter?
Pumpkin pi!

Mathematician: Pi r squared.
Baker: No! Pies are round. Cakes are squared.

4. Listen to The Pi Song. Seriously. Check Youtube.
5. Woo someone by referring to them as a “QT π.”
