Today is March 14—you know, 3/14—making today National Pi Day.

As you might remember from those algebra classes you took at some point in the past, pi is an irrational number that's most easily defined as the ratio of a circle's circumference to it diameter—and since a circle's circumference is always juuuust a bit more than three times its diameter (though not exactly so,) the figure is often represented as being 3.14159265...and stretching on into infinity. Which is cool.

But really, Pi Day is just a damn good day for nerds to gather around and eat pie. Which, again, is cool.

The Loft Cinema, however, has taken things into a different direction, as they'll be screening Darren Aronofsky's debut feature film, Pi this evening at 7 p.m.

A film synopsis from The Loft Cinema:

In Pi, reclusive math genius Max (Sean Gullette) believes "everything can be understood in terms of numbers," and that patterns exist everywhere: in nature, in science, in religion, in business. Max spends his days searching for these patterns in everything, when he’s not suffering mysterious headaches, playing Go with a former teacher or fooling around with an advanced computer system named Euclid he’s built in his NYC apartment. Unfortunately, Max is not the not the only one looking for these universal patterns, and soon everyone from Wall Street investors, looking to break the market, to Hasidic Jews, searching for the 216-digit number that reveals the true name of God, are trying to get their hands on the secrets in Max’s head. Distracted by blackout attacks, hallucinations and paranoid delusions, Max begins to lose his grip on reality as the increasingly dangerous world closes in around him.

Following the film, University of Arizona professors Bruce J. Bayly and Kenneth D. McLaughlin will be leading a discussion on pi, infinity, and other such weighty topics.
