Deletion of Tau (mathematics)

Comment: This has been around for ten years now, and has recently been covered by New Scientist and BBC Radio 4 (and that's just in the UK). Those alone are enough to demonstraate  - end of story. We don't need articles for ''both'' Michael Hartl 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, it also make a lot of sense from my viewpoint
