Describes
a system of particles in terms of a wave function defined over the configuration
of particles having distinct locations is implicit in the potential energy function that determines the wave function, the observable dynamics of
the motion of such particles from point to point. In describing the energies,
distributions and behaviours of electrons
in nanometer-scale
structures, quantummechanical
methods are necessary. Electronwave functions help determine the potential energy surface of a molecularsystem, which in turn is the basis for classical
descriptions of molecular
motion. Nanomechanicalsystems
can almost always be described in terms of classical mechanics, with occasional quantummechanical
corrections applied within the framework of a classical model.

largely computational physical theory explaining the behavior of quantum phenomena, which incorporates the theory of
special relativity. Despite dilignet attempts, general relativity has not
been sucessfully incorporated into quantum
mechanics. [NTN]
