Celebrate Pi Day With These Mathematical Reads

It’s not the loneliest number, but it might be the most famous. Pi (or π) is commonly defined as the ratio of the circumference of a circle to its diameter. π has been calculated to trillions of digits, but most people just know the first few, namely 3.14—hence, Pi Day, celebrated every year on March 14th (3/14, get it?).

If you haven’t already rolled your eyes and closed this tab, you might be the type who’d enjoy reading more about Pi and/or math in general, so here are some librarian recommendations. And don’t forget to enjoy a slice of Pi(e) while you’re at it.
