We’ve had math on our minds at Scholastic lately, so it feels right to celebrate this…happy Pi Day! As I’m sure you know, Pi Day celebrates that crazy useful number pi, in addition to being Einstein‘s birthday. It’s big doings this year, the 20th anniversary of the celebration created by physicist Larry Shaw, as everyone from the NY Times science guy to the Huffington Post is blogging about it. In Detroit folks are celebrating by writing haiku, while in Minneapolis (and lots of other places) they’re marking the day with pie.

Of course, the biggest party is likely to be at the Exploratorium in San Francisco, site of the original Pi Day. We’ve got a couple of Kid Reporters there who will report back to Scholastic News. As for me, I’ll be celebrating my own way: thinking about physics, eating lemon meringue.
