## Main Question or Discussion Point

When one compares the fundamental solution for Laplace's Equation one might note that in 2 dimensions this solution becomes unbounded as r goes to infinity while in 3 dimensions the solution goes to zero as r goes to infinity.

Now I understand both mathematical derivations so my question is not about that. What I would like to know is can someone give me a good explaination in terms of the possible physics being modeled by this equation that would explain this difference between the 2d and 3d case.

That is I would like a real world explaination as opposed to simply a mathematical explaination.
