I would like to know which alleged "group" advocated for the redefinition of pi to pi=3. I tend to think it is a rumor as well. What is the documentation for that statement in the book? Does the author have any? I suspect his source is as reliable as donh's?
Did you get your T-Shirt yet?
You're kidding, right?
So all those footnotes in all those academic papers that refer to books are not legitimate sources? After all, looking it up in a book would require getting off your duff and going down to your local public library.
The group was at Emporia State, in the early 1980's, and had a name something like 'International Society for the study of Pi'. When I get home this evening, I will post exact details.
