## Kepler Celebrating Pi Day with a Little Pi Humor

Today is that wonderful time of year where we get to celebrate one of mathematics wonderful little values: π. Many celebrate March 14th by competing in pizza pie or apple pie eating contests. Some even go as far as eating some pie at 1:59PM (or AM if you’re awake). Here at Kepler, we employ several…let’s call them math-enthusiasts. You know, those who loved calculus class and enjoy building mathematical models until 4 in the morning. The ones that loved proofs in geometry, yep those guys. Well, because our math-enthusiasts are dear to our Kepler family, we wanted to show our Pi-appreciation, by passing along some Pi-humor. Enjoy!

### A Little Pi-Humor

What did π say to √(-1)? “Get real”. And what did √(-1) say in return? “Be rational”.

What do you get when you divide the circumference of a Jack-O-Lantern’s by its diameter? Pumpkin Pi

What do you get when you divide the circumference of the moon by its diameter? Moon Pi

What do you get when you divide the circumference of the sun by its diameter? Pi in the sky!

Mathematician: Pi r squared. Baker: No pies are round, cakes are square!

A mathematician, a physicist, and an engineer are all given identical rubber balls and told to find the volume. They are given anything they want to measure it, and have all the time they need. The mathematician pulls out a measuring tape and records the circumference. He then divides by two times pi to get the radius, cubes that, multiplies by pi again, and then multiplies by four-thirds and thereby calculates the volume. The physicist gets a bucket of water, places 1.00000gal of water in the bucket, drops in the ball, and measures the displacement to six significant figures. And the engineer? He writes down the serial number of the ball, and looks it up.
