Why? Well, people asked, and what better way to celebrate pi day?

The idea for this video, as well as the live shots, came from Ben Hambrecht, with the writing and animating done by Grant Sanderson.

- Martin Mattmüller from the Bernoulli-Euler center for helpful discussion
- Michael Hartl, author of the Tau Manifesto, for pointing us to obscure references
