To some degree, all technology is based on math. And in 1998, the noble field of mathematics played host to a hoax with a curious history. By way of endlessly forwarded emails, word got out that the Alabama state legislature had voted to change the value of pi to 3.0, in accordance with Biblical scripture. The story made headlines for a few days until it was discovered that the article was actually intended to be parody. The parody was itself a riff on previous urban legends going back decades. Those hoaxes, in turn, were based on an actual but obscure 1897 attempt to legislate pi in Indiana -- but for practical, not religious reasons. Twirling, twirling into madness!
