Happy Pi Day from all of us at the Bartlett Public Library! We celebrate today as Pi day since the date, March 14th, is the same as the first three digits of π (3.14).
You can learn more about the mathematical concept of Pi in Why Pi? by Johnny Ball, in our juvenile nonfiction section at j530.8 BALL.
You can celebrate Pi Day with challenges from NASA scientists and engineers as part of their Pi Day Challenge! Good luck!
