Yesterday (3/14) was “Pi Day.” Source of image: http://www.mathwithmrherte.com/pi_day.htm
After school yesterday, my daughter Jenny told me that in her sixth grade class with Barbara Jens, they had celebrated “Pi Day.” I didn’t get it until Jen pointed out that the date was 3/14 and the first three digits of pi are 3.14.
Being a hoosier by birth and upbringing, Pi Day reminded me that in 1897 the Indiana House of Representatives unanimously passed a bill legislating the wrong value of pi. It would make a better story if the House had taken this action based on a literal interpretation of the bible, which gives the value of pi as an even 3. But apparently the House action was based on a mistaken “proof” offered by physician Edwin J. Goodwin. Fortunately for the reputation of Indiana government, a mathematician visiting the state capitol for other reasons, convinced Senators of the mistake, and consideration of the bill was postponed indefinitely in the Senate, before it could become law.
For my source, and more details, see Petr Beckmann’s wonderful book:
Beckmann, Petr. A History of Pi. New York: St. Martin’s Press, 1971.
