  The Feynman quantum-classical isomorphism between classical statistical
mechanics in 3+1 dimensions and quantum statistical mechanics in 3 dimensions
is used to connect classical polymer self-consistent field theory with quantum
time-dependent density functional theory. This allows the theorems of density
functional theory to relate non-relativistic quantum mechanics back to a
classical statistical mechanical derivation of polymer self-consistent field
theory for ring polymers in a 4 dimensional thermal-space. One dynamic
postulate is added to two static postulates which allows for a complete
description of quantum physics from a 5 dimensional thermal-space-time ensemble
perspective which also removes the measurement problem. In the classical limit,
a cylinder condition naturally arises as the thermal dimension becomes
irrelevant, providing a justification for using 5 dimensions and a cylinder
condition in general relativity, which is known to produce 4 dimensional
space-time gravity and Maxwell's equations. Thus, in this approach, the
postulates of electromagnetism become derived results of a special case of a
ring polymer interpretation of quantum foundations.
