Today is National PI Day. You’re probably expecting some kind of PIE joke, right? Well, I’m not gonna do that. This is serious, ok? PI is a mathematical something or other that never, ever, ever changes. It’s ALWAYS 3.14 (followed by a million more numbers which never, ever, ever change). You can always count on PI to stay the same. The House of Representatives created this holiday back in 2009 (HR224) in the hopes it would excite young minds around the nation about mathematics and science. So… is it working??
