Happy National Pi Day
DAVID GREENE, HOST:
And today's last word in business: Pi in the Sky.
Today, March 14th, 3-14, is Pi Day. In case you didn't know, it's actually a national holiday - certainly an important day for math lovers. In Austin, festivities started early - with skywriting. A company called AirSign tried to write the long famous ratio across 100 miles of sky. It turned out writing Pi in the Sky was a little easier.
RENEE MONTAGNE, HOST:
In San Francisco, there's the Pi Procession. If you show up, you'll get a number, one through 9, and line up in the order of Pi. And from coast to coast, bakeries, of course, of course, are offering Pi Day specials.
GREENE: And, of course, there are some great jokes - Pi jokes. Renee, did you know that 3.14 percent of sailors are Pi rates?
MONTAGNE: Great joke, David.
GREENE: Thank you. Good for a Friday.
GREENE: That's the business news on MORNING EDITION from NPR News. I'm David Greene.
MONTAGNE: And I'm Renee Montagne.

UNIDENTIFIED MAN: (Rapping) ...we also need to know called Pi - mathematical concepts, they everywhere. Why?
