Pi Approximation Day

The ratio of a circle's circumference to its diameter is both an important fundamental constant of the universe (though some would argue that it contains a hidden coefficient that ruins everything) and a transcendental, irrational number. This is inconvenient, since the digits in pi go on forever in a manner that's fundamentally unpredictable, and despite this they matter, all the way down. For practical applications this in't really a problem (since as many digits as matter can be easily memorized with a sufficiently nerdy poem), but that hasn't stopped people from coming up with cleverly stupid workarounds. Ryan North, for example, proposes celebrating Pi Approximation Day on July 22, since 22/7 is reasonably close to the true value of pi for the first few digits. You can read more about that here:

Too be honest, endless chains of random digits don't excite me much, even when they correspond to real things like circularity, exponential growth, or efficient optimization. I'm actually a fan of North's comic more for its maxim at the end, "Failure is just success rounded down." All this aside, pi does seem to have an almost rapturous appeal for some people, witness the transcendental number subplot in the book version of Contact. July seems just as good a time to celebrate nerdiness and mathematically-inclined awe as March, so why not?

Also this was supposed to be posted on July 22. I'm not very good at keeping things on schedule. I'll refrain from apologizing if for no reason other than to avoid winding up like this guy.
