(The actual Pi Day is 3-14.)

Science Central Volunteers and Professor Adam Coffman from IPFW set up the "Pi Day" activity table at Science Central. The main project: build the "Pi Chain," color coded by digits of Pi! |

Here's the color code |

Pi Poster (more precisely, a "transcendental" number is not a root of any non-zero polynomial with integer coefficients) |

Kids having fun |

"5" golden rings |

A topological error? |

The length of the chain by Saturday afternoon (starting with pink = 3 on the far right) |

Gets longer by Sunday |

There's Pie in the break room |

Did the Indiana state legislature really pass a law in 1897 declaring
pi to be equal to 3.2? No, it almost did, but a Purdue math professor happened to be in the capitol at the time and stopped it: |
