 * Reason:Highly informative diagram, explains τ (tau) simply and accessibly. Even I can understand the basics of it.
 * Articles in which this image appears:Turn (geometry), Draft:Tau (Proposed mathematical constant) (when it goes live it'll be an article)
 * FP category for this image:Featured pictures/Sciences/Mathematics
 * Creator:Lucas V. Barbosa

 * Support Nice, could be a cool boot animation as well! ///Euro Car  GT  02:10, 5 September 2014 (UTC)
 * Oppose Honestly, the way it's done, it makes it look like τ = 2π-6, because it lingers on the last partial segment. See, the thing is, this is an adjustment of the much clearer File:Circle_radians.gif - which was meant to explain radians. Radians are a concept completely unnecessary to explaining tau, but, since it's trying to show this as a matter of angles, instead of a mere ratio of radius to circumfrance, it adds unnecessary complexity. Further, the original is a clearer explanation of radians - counting to three and a bit is far simpler than counting to 6 and a bit, takes less time, and is a little easier to intuitively understand.
 * Explaining tau should not require explaining radians, and, given tau is basically a fringe concept, the clearer, "2π radians in a circle" version should be used in all articles not about tau itself Adam Cuerden (talk) 04:29, 5 September 2014 (UTC)
 * I think that the caption should at least make it clearer that main purpose of this diagram (as distinct from File:Circle_radians.gif) is to illustrate "tau", rather than mentioning it at the end as a kind of afterthought. How necessary or desirable it is to involve the concept of radians in an explanation of "tau", I'm not sure. I have never heard of this use of tau to mean 2*pi. 109.147.185.178 (talk) 22:45, 7 September 2014 (UTC)
 * In all honesty, it's kind of a crank idea. I mean, the maths work, but it's inherently unnecessary. Got a bit of newspaper coverage a while back. Adam Cuerden (talk) 04:54, 13 September 2014 (UTC)
