So I asked a question yesterday about how to do quantum mechanics with a Sturm-Liouville Schrödinger equation. Somehow it has disappeared completely :(
If I had to guess I might have accidentally deleted it in the app. I did some editing there and have pretty clumsy fingers. However I have deleted other things on purpose before and then I could just find them in the reputation notifications or elsewhere. I believe that also gave the option to undelete.
In this case the question seems to have disappeared completely though, so I'm not sure that accidental deleting was the reason. Can someone help me recover it?
