## Pi Day Is Coming — But Tau Day Is Better 241

PerlJedi writes

*"A few months ago, a Tweet from Randal Schwartz pointed me to a YouTube video about 'Triangle Parties' made by Vi Hart. My nerdiness and my love of math made it my new favorite thing on YouTube. Now, with Pi Day coming up later this week, I thought it would be an appropriate time to point people to another of her YouTube videos: Pi is Wrong. The website she mentions at the end, Tauday, has a full explanation of the benefits of using Tau rather than Pi. Quoting: 'The Tau Manifesto is dedicated to one of the most important numbers in mathematics, perhaps the most important: the circle constant relating the circumference of a circle to its linear dimension. For millennia, the circle has been considered the most perfect of shapes, and the circle constant captures the geometry of the circle in a single number. Of course, the traditional choice for the circle constant is pi — but, as mathematician Bob Palais notes in his delightful article "Pi Is Wrong!", pi is wrong. It's time to set things right.'"*

Darn.

I read that wrong.

I say we stick with pi. It's too labor-intensive to rewrite all the textbooks to read "tau" instead of "2*pi" and reteach everyone the new formulas.

Being English, old-fashioned and inaccurate, I prefer to celebrate Pi Day on July 22nd.

Tau is twice the constant Pi ever was!

For now I don't really see the practical use of remembering Pi to that extent.

Chicks.
