Time Variation Of Pi

Since at least as far back as the work of Dirac in 1937 (see here), there has been discussion about whether the fundamental constants of physics might vary with time. Unfortunately, some of these ideas have been stretched by young-earth creationists, in a completely unscientific way, to bolster their hypothesis that the universe was created just a few thousand years ago.

In honour of Pi Day (yes, I know it was two days ago), consider this humorous (and brief) article on the time variation of $\pi$ by Robert J. Scherrer of Vanderbilt University.
