Knowledge and understanding are quite different. Only understanding can lead to being, whereas knowledge is nothing but a passing presence in it. (G.Gurdjieff)

comment Poisson equation in 2D and 3D: geometrical reason for the difference
Thanks. It sounds pretty clear. But it seems to rely on the fact that I am allowed to have $F=\nabla\phi$, whilst the mathematical equation for $\phi$ alone has already this property. Does that present any limitation to this argument?

Yes, you're right. Could you do anything to migrate it?

edited my friend, Not that it changes anything, but apparently over here people do not like to be asked questions straightforwardly any longer.

comment Why (and how) do foods stick to a pan?
@JohnRennie I do not agree, take for example lubrication, the tendency for protein-rich foods to stick more easily, etc. I am asking what is the physical counterpart of the bond-dominated explanation that chemist would give.
