48:. An interesting discussion, with a few different points of intersection. First, the keeps have the better of it from a notability standpoint. The original nomination specifically addressed sourcing, and invoked the GNG; this was adequately rebutted, and a number of the comments acknowledged explicitly or tacitly the nontrivial coverage. Thus, the administrative action here is to close the discussion as keep. However, I see a strong consensus that the article should be renamed or merged somewhere, and given the degree of participation here I am prepared to call this a local consensus to the effect that, while notable, the topic is best addressed within another article. This well within editorial discretion, however, I do not see agreement as to a merge target. So, I am making an simple editorial decision (which anyone should feel free to revert) to move the article to 284:. This is a non-notable use of the term in mathematics, basically the effort of a single educator that, for some reason, has been picked up by a few mainstream media outlets. In the extremely unlikely event that thus notion produces a lasting scientific impact as evidenced by its use in peer reviewed scholarly sources, the article can always be spun out afresh. There are, at any rate, much more established uses of the symbol tau in mathematics (in the theory of elliptic curves, for instance) that the present article's focus is assigning grossly inappropriate weight to a thoroughly marginal usage. 2185:
discarded: for example, new TV celebs get in here rather quickly. So many less-useful and less-long-lasting entries arrive in Knowledge (often celeb bio details); this appears to have much longer-lasting potential influence. I suspect that if you're worried about numbers interested in this, if left for six or twelve months you'll find the diffusion S-curve steepens and numbers multiply exponentially. I advise caution, and waiting. Already academics as far from California as Leeds, are making youtube vids about it, (eg
343:. I agree with Sławek that the current title is bad because too many things in mathematics are called τ and this one is probably not in the top fifty. Just the same, the proposal to work with 2π instead of π has received enough coverage that it may be "notable" in our WP-specific sense of the word. It's kind of marginal, and I wouldn't like to see an article that pulls together independent proposals and makes a commonality out of them, unless some secondary source has already done so. -- 2115:
being the logic of the idea and its social implications. This isn't actually strict mathematics, but rather a thoughtful socio-historical campaign about how we view established terms and constructs.

and Tau, but we should cover this issue, under at least one of those name, with a redirect from the other. Mathematicians who think it's a nonsense are simply irrelevant - the point is that the campaign exists and is notable, not whether it's right or wrong. As a physicist more than a mathematician,

for lack of notability. If you were to hand me a τ and ask what mathematical symbol I thought it represented, I would probably guess time. I might guess the period length of a periodic function or maybe (as Sławomir Biały pointed out above) a point in the complex plane defining an elliptic curve.
1262:
Merge means merge, in other words take the useful material in the article and copy it to the other article. There is already a section ("Mathematical constant") that talks about tau being used as a unit. I think the redirect makes sense; don't assume someone reading about tau as a unit will know it
1413:, near the top of the Yahoo news stories this morning, so I reluctantly conclude that the GNG has been met (not by that story alone, but it's the one that shows the camel's back has been broken). Still, e (exp tau/2*i) = -1 is ugly where the original is elegant, and shows why this is a lousy idea. 2119:
is a Terrible idea, because it would confuse a page about how we currently perceive the maths of circle geometry, turns, with he ideas about how we may wish to challenge those terms. And thiis page is not in maths territory, but more in (Thomas) Kuhn and social criticism territory. And no less
2305:
Agree with Teapot for a different reason. Tau's page is not the same as the Turn article, because the reason for reading each page is different. One is to explain how turns in a circle work, the other is to explain how a naming convention is mathematical bad practice (occam) and aesthetically

Fair point Runningonbrains (the post you replied to was mine, not signed-in). To me, it appears to be notable enough, and I was merely cautioning against dismissing it as mere flippancy due to its rhetorical style. It's true that the data are quite recent, but not all new-ish things need be

I'm quite sure I've heard about a movement to change from pi to 2pi as the fundamental constant before this year. I've seen both tau and another symbol used for this constant, where the other was a three-legged pi. (That might suggest a different page name, but not deletion.)

Could you point us to the policy that says that, or is it just your opinion? For what it's worth, my opinion is that a Merge means that the content doesn't deserve its own article, but at the same time it shouldn't be deleted if possible. However, the merge target

There is no reason to have a separate article for this one term when it is one of a few criticisms of the use of pi (which are voiced by a SMALL minority of mathematicians) which are all essentially along the same line. So a 594:. As I and others have already pointed out elsewhere, this usage is quite marginal in mathematics. In fact, as far as I'm aware no mathematical sources even use this notation for 2π. If you want, you can move the article to 1869:

I thought this had been around for a few years, but maybe I'm wrong. I've heard of it from multiple independent sources, some of them not people who usually pay any attention to mathematics, so I'm slightly inclined to say

The fact that the proposal has not resulted in a change of mathematical practice is not relevant for its notability.  -- 2408:. This is an old issue that has made it in the news now. It looks like its a fringe issue because it dates back from before the internet era. It's not a huge issue, of course, but enough to merit a Wiki article about it. 206: 71:

for me there's no real question that the proposal to use a symbol for 2π instead of π is notable. The questions are, does it deserve a whole article, and if so, what should that article be called? I think the name
