My kids love holidays, especially the geeky ones. Wednesday, was a bigger celebration than Christmas at the Heart House. It was the birthday of Albert Einstein (of e=mc2 fame), Frank Borman (one of the first astronauts to circle the moon) and Billy Crystal (aka Miracle Max from The Princess Bride). If that wasn’t enough, it was also National Potato Chip Day and Learn About Butterflies Day. In addition, Google posted a special doodle honoring origami expert, Akira Yoshizawa. But the thing that really made the day for my kids was that it was Pi Day. In honor of such a monumental day, I would like to share the Pi pie that we made to celebrate.
