This document introduces the “Periodic Table of Oscillations,” an ontological framework that organizes all physical, biological, and cognitive processes as manifestations of fundamental oscillatory principles. It proposes that oscillation is the primary structural and energetic pattern of existence, preceding geometry, matter, and biological evolution. The table arranges oscillatory modes into a coherent system that links photon behavior, cellular energetics, evolutionary transitions, and human consciousness. It serves as the central reference model connecting the author’s broader work on oscillation, evolution, gamma radiation, and philosophical ontology.
