We have obtained an equation, which, according to the author, will make it much easier to calculate the states of atoms, molecules and solids. Our equation is a modified Schrodinger equation. Moreover, the Schrodinger equation, according to Nobel laureate Paul Dirac, contains all the chemical problems. The solution of this equation is simpler than the solution of the Schrodinger equation and the Hartree-Fock equations. If accurate calculations prove that this equation gives accurate results, this equation will be as important as the Schrodinger equation. This equation recorded by the author in 1986. Scientists cannot accurately solve the Schrodinger equation for multielectronic systems. Scientists cannot write down an exact but simpler equation similar to Schrodinger's equation. Scientists and scientific journals have been rejecting our equation for 36 years. However, no one has proved the wrongness or uselessness of this equation yet.
