[UNDELETED]

<A HREF="http://mathoverflow.net/questions/243030/unreasonable-application-of-mathematics-to-the-other-areas/243033#243033">Unreasonable application of mathematics to the other areas</A>

I may be biased, but the deletion of this question, together with both its answers [and Todd's very pertinent correction], seems an overly drastic action, which I would suggest to undo.

The SE deletion policy, *"a post that no longer adds anything to the site should be deleted"* does not seem quite applicable here.
