The variational principle of extremum is stated and proved for electromechanical systems of arbitrary configuration wherein the electromagnetic, mechanical, thermal hydraulic and other processes are going on. It is shown that for such systems there exists a pair of functionals with a global saddle point. For systems without electric circuits the suggested principle is equivalent to the minimum action principle. The principle is generalized for the systems described by partial differential equations, and in particular by Maxwell equations. A speedy universal algorithm for computation of such systems with arbitrary excitations is described. In this algorithm a method of searching for global saddle point simultaneously on two functionals is realized. The book contains numerous examples, including those presented as M-functions of the MATLAB system.

Quantum physics differs from classical physics in the methods of study, and both of them consider the methods of the opposite side unacceptable for themselves. The author proposes the solution of some problems that are the privilege of quantum physics, using the methods of classical physics. At the same time, the author does not introduce any new postulates, but uses one and only tool, which is recognized by both physicists - the Maxwell system of equations. Strong interactions, atomic model, elementary particles, vacuum structure, electric charge, static electric field, electric current are considered.
