Pi

We all know that Pi (π) is the ratio of the circumference of a circle to its diameter, is a transcendental number, with a value of 3.141592653 to the first nine decimal places, and is commonly stated as 3.14.  But if Edward J. Goodwin had his way, it would, at least in Indiana, have been changed to 3.2.  In 1897 he

convinced Indiana State Representative Taylor Record to introduce a bill to do that in the state’s General Assembly.  Fortunately, before the bill got to the Senate, a Purdue University professor saw it and put the kibosh on it stating “The Senate might as well try to legislate water to run uphill as to establish mathematical truth by law.”  The Reader's Digest article detailing the whole story is at the link below.
