Today is March 14, which means one thing: It’s Pi Day! (For those of us who slept through math, pi = 3.14 = March 14) To celebrate, I thought we’d break out the number’s 3.14 greatest pop culture moments:

1. The Net (1995)

This cyberthriller starred a young Sandra Bullock as a computer geek who stumbles onto some amazingly vague internet conspiracy — one that she unlocks by clicking on a mysterious “pi” symbol on her computer screen. Nowadays, the scariest part of the movie is the fact that I actually remember when 2 MB floppy disks were considered cutting edge. Yikes.

2. “Pi” by Kate Bush (2005)

How many other mathematical constants have their own theme song? (In your dreams, Khinchin’s.)

3. Pi (1998)

Filmmaker Darren Aronofsky (The Wrestler) became the toast of the independent film world (and the bane of copy editors everywhere) when he chose the symbol as the title of his debut thriller.

And what about that extra .14? We’ll leave that up to you, readers. Tell us your favorite pop culture pi moments in the comments!
