This site describes a new model of atoms and molecules in terms of classical continuum mechanics in three space dimensions in the form of a free boundary problem for a system of partial differential equations in non-overlapping electron charge densities.

The new model is referred to as realQM (real quantum mechanics) as a model with interpretation in physical terms, to be compared with the model presented in books referred to as stdQM (standard quantum mechanics) with non-physical interpretation as particle statistics (according to the Copenhagen Interpretation by Bohr-Born-Heisenberg).

realQM is computable while stdQM is uncomputable. realQM has physical meaning while stdQM has a statistical non-physical meaning.

realQM combines simplicity, generality and physicality. The question is to what extent realQM describes true physics.

One may argue that macroscopic physics may be complex/random as consisting of many interacting microscopic pieces, while microscopic physics consisting of few pieces can only be simple/deterministic. With such a realQM perspective, the ground state of an atom is simple and leaves no door to the randomness of stdQM.

The first live presentation of realQM to the World was given at the conference 50th Anniversary of Journal of Structural Mechanics, August 24-25, 2017, Vaasa, Finland as
