Dear Rational Thinkers,

Today we’ll eat a little pie. That’s because Saturday is 3/14/15 and those are the first five digits of the constant pi. In your mathematical career, you’ll learn about and use pi–to find the circumference of circles, the area of circles, and pretty much anything about circles or curves. It’s a number that shows up throughout nature. It seems to represent something important about order and chaos.

Sincerely,

Mr. H
