>> [Inaudible] chanting.
>> Pi. Pi. Pi.
>> Today is March 14. 3-14. And the time is 1:59. You know what that means? The first six digits of Pi. I'm Kara Tsuboi at the Exploratorium in San Francisco, where we're celebrating Pi Day.
>> There's so little we can celebrate about Mathematics in everyday life. It's this amazing number. It never stops. It never repeats. And to have such a simple thing like the ratio of a circumference to a diameter of a circle that creates a number that never ends, that's interesting.
>> It's the interdimensional rotator, how to get from one dimension to the next dimension.
>> Or, in the layman's terms, a number used to help calculate a circle's area and circumference.
>> People might actually run into Pi in their everyday life.
>> The Pi procession kicked off events, and like the previous 19 years, it is led by Larry Shaw, the party organizer.
>> Everybody knows about it but it's mysterious. And to have some fun with mysterious things is pretty much [inaudible].
>> From the Pi procession, to the Pi chain reaction demonstration, to the pizza pie tossing, to the pie throwing contest, all forms of Pi, mathematical or not, were honored at this celebration.
>> That's Pi. It's time to party.
>> Making his first appearance to the Exploratorium's annual Pi party was this little guy, three-month-old baby Pi. And yes, that is his real name.
>> It's kind of a gift that we're giving him, that wherever he goes that he knows that his name means that he's got infinite possibilities.
>> Pi's integral to a circle, but it also goes on and on forever, so it kind of combines these two elements that seem to contradict each other.
>> And what do you think of your name?

>> What kind of Pi Day would end without a sweet treat? Pecan, lemon meringue, cherry, strawberry rhubarb, pumpkin, an infinite number of pie options, just like Pi, itself.
