Cu2+(aq) + OH-(aq)...
I have recently been working on a project regarding black holes and the spaghettification aspect of it interests me quite a bit. So, I have set out to try to derive some mathematical descriptions of the geometry of the object being spaghettify.
I have spent a few hours (uncessfully) trying to...
