Actually his "discoveries" didn't just claim that pi was 3.2, it claimed (sometimes implicitly) several values. The wikipedia article is more informative:<p><a href="http://en.wikipedia.org/wiki/Indiana_Pi_Bill" rel="nofollow">http://en.wikipedia.org/wiki/Indiana_Pi_Bill</a><p>Google finds many more references of varying detail.<p>Most people know the approximation 22/7, and many people actually think this is the exact value. A much better approximation is 355/113, unreasonably good, as evidenced by the unusually large integer in the continued fraction expansion of pi.
