Recreational *mathemusician* Victoria Hart—aka Vi Hart—gives overwhelming (and fun!) evidence that clearly demonstrates that Pi is a stupidly common number and the fascination of people with this number is just dumb.

Martin Krzywinski is an artist. No, wait, he's a mathematician. Actually, scratch that: he's both, and he can make the number Pi look insanely beautiful.

How many numbers of Pi can you rattle off? Probably not many. Probably even fewer if you're drunk. But you can at least cheat with these glasses from TheUncommonGreen that are printed with hundreds and hundreds of digits from the mathematical constant.

Any eyes in San Francisco that weren't focused on Apple's announcements yesterday might have noticed something peculiar in the skies over the Bay area.

What do you get when you transpose the first 31 digits of the number pi into musical notes? Math that's never sounded so good. And if ever an unofficial holiday needed an anthem to get some much-deserved recognition, it's 3/14. [Reddit via Geekosystem]
