Introduction: The Path Integral as Sum Over All Phase Configurations

The path integral is one of the most powerful formulations of quantum field theory. It is a sum over all possible field configurations, weighted by the exponential of the action. In the Wave Ontology framework, the path integral is a sum over all phase configurations.

In classical physics, a system follows a single path — the one that extremizes the action. In quantum physics, all paths contribute. The path integral sums over all possible paths, with each path weighted by the phase of the action. This is the quantum amplitude.

In the Wave Ontology framework, the path integral is the sum over all phase configurations of the Hz field. Each phase configuration contributes a phase factor $e^{i S[\tilde{\Psi}]/\hbar}$. The sum over all phase configurations is the full quantum amplitude.

This chapter explores the path integral in the Hz field: the functional integral, the phase action, Feynman diagrams, the propagator, the effective action, quantum fluctuations, and the stationary phase approximation.
