Abstract
In his 2 volume chef-d'oeuvre “Treatise of electricity and Magnetism” J.C.Maxwell (among thousands of much more important claims) formulated the following statement.

Given any configurations of N fixed point charges in R^3, the electrostatic field created by them has at most (N-1)^2 points of equilibrium.

Maxwell’s arguments are incomplete and this problem was considered much later by M.Morse and revitalised about two decades ago. However Maxwell’s original claim is still open already in case of N=3 charges. In my talk I will survey what is known in this direction and, in particular, formulate a calculus 1 problem which currently still remains unsolved.
