Pi Day at Science Central in Fort Wayne

Saturday/Sunday March 10-11, 2007.
(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:

A PDF file of Adam Coffman's handout for Pi Day: PDF
includes Niven's one-page single-variable calculus proof that pi is irrational
and comments on repeating and non-repeating decimals.
