There is an urban legend that says Indiana passed a law implying pi = 3.

(Because it says so in the bible...)

Dear Vincy,

I hope that in school you also learned that 22/7 is an approximation. Please consult your local mathematician for a proof that pi != 22/7. A quick search will provide you with volumes of information on what pi is, how it may be calculated, and calculations out to thousands of digits.

Cheers,

Josh
