Thursday is Tau Day! Let's Party!
628 is a special number and a special day. We'll all meet at the local bar and drink a round to Tau!

Yeah, that is what came to mind first for me as well (of course my 40K army is Tau so..), but I think he's talking about this:
Tau Manifesto
The TL;DR which the details of are way over my head, is that Pi as the constant to determine circumfrence from diameter is wrong and an increased accuracy can be gained by using a constant derived from the radius rather than the diameter, a constant it's proponents name after the Greek letter Tau.

Re: Thursday is Tau Day! Let's Party!
I think Tau is actually a better choice for fundamental constant than Pi. I use Pi much more often with a 2 in front of it, than without one. The essay explains pretty clearly why. The radius simply is a more fundamental concept than the diameter.
For people experienced in math, it of course doesn't matter which one you use. Both work equally well. But I can see that using Tau over Pi would have great pedagogical benefits when teaching math to kids.

Maybe so but think of how deeply the character pi is ingrained, how many books and programs it's used in. Think of having to keep up with both until pi dies. sigh

Re: Thursday is Tau Day! Let's Party!
Oh look, this argument again. (I have no strong feelings one way or the other. A lot of math is pretty arbitrary anyway, like having 360 degrees in a circle.)
Re: Thursday is Tau Day! Let's Party!
The circular constant Pi = 3.14, thus 3/14 (March 14) is Pi day
The new, improved, easiertouse, circular constant Tau = 2*Pi = 6.28, thus 6/28 (June 28) is Tau day.

Re: Thursday is Tau Day! Let's Party!
I've become familiar with the "Pi is wrong, Tau is right" idea just recently (a friend emailed me the link to the Tau Manifesto). Even though I agree with it in principle and am personally considering switching to Tau in the future period, I don't really feel the urge to celebrate Tau Day. Neither did I ever really feel the urge or wish to celebrate Pi Day.
It is a good conversation starter, though

wat. >< It's the same accuracy. All it's saying is that you can replace instances of 2pi with just the 1 tau.

*shrug* I've seen more deeply ingrained things go by the wayside when it was their time. It would be an improvement if it were to be done, but it won't get done if we never have the courage to get started.

Degrees? What are degrees? Do you mean radians? If so, there are 2*pi radians in a circle, not 360.

You really should be able to do a substitution that simple if you're doing college maths.

I was lamenting the loss of a thing of beauty, however consider me all it, I don't have to deal with it at all. However you run down everyone that is going to have to know, I'm going to have a beer for pi and a shot for tau.

Uh huh, no. I had to memorize that g is 32 feet per second squared in high school and 9.8 meters per second squared in college. I got over it, and that was the same symbol.
When I get my own math classes, my intention is to teach geometry and trigonometry from tau. First, it's a trivial conversion process, so people can substitute tau = 2 pi in their formulas or on their calculators. But, more importantly, as Vi Hart's video points out, it makes geometry and trigonometry more intuitive. The angle that splits a circle into seven equal pieces has measure tau/7 radians. With pi, you've got to juggle that annoying factor of 2 and the hassle obscures the deeper lesson. So I expect that tau makes it easier to teach and learn math, and that will even make it worthwhile to teach the conversion factor for a half a generation until all the textbooks and calculators are up to speed.

Re: Thursday is Tau Day! Let's Party!
Switching to Tau would also remove the beauty from the most elegant equation ever. It would be the quantity of e to the tau over two times i plus one equals zero (or e^((t/2)*i)+1=0). Weak.

Have you even read the Tau Manifesto, as you're so determined to speak against Tau?
You could also have e^(i*Tau)=1+0, which also shows a relationship between e, i, Tau, 1, 0, just as the one with Pi does.

It would become e^tau*i = 1
So it would remove the 1 kludge

Except having "+0" on an equation is about as inelegant as you can get; you didn't even perform the easiest simplification available!

Right. Sorry, it's been a while since I read the Tau manifesto or one of the Tau rants (a year or so). It's still missing the point. The long form of Euler's equation combines the five most important numbers math.

Only due to further details about how we write equations, not due to any fundamental truth.
I personally find e^{iπ} = 1 much more elegant than e^{iπ} + 1 = 0. The latter uses an extra unnecessary symbol (or two extra symbols, depending how you count), and confuses the meaning (I have to mentally translate it to the former equation to think about what it really means).
And if you're not willing to eliminate unnecessary symbols, then there's nothing inelegant about e^{iτ} + 0 = 1, or, for that matter, e^{0iτ} = 1.

The shifting of the 1 around is a kludge so that the equation includes both 1 and 0, but it's not inelegant  having +0 is really horribly inelegant.
