  We take attention to the singular behavior of the Laplace operator in
spherical coordinates, which was established in our earlier work. This
singularity has many non-trivial consequences. In this article we consider only
the simplest ones, which are connected to the solution of Laplace equation in
Feynman classical books and Lectures. Feynman was upset looking in his derived
solutions, which have a fictitious singular behavior at the origin. We show how
these inconsistencies can be avoided.
