Recursive Harmonics (RH) proposes a materialist theory of collapse rooted in field recursion and dialectical contradiction. Beginning with minimal assumptions—motion, memory, and deviation—RH constructs a unified framework in which mass, spin, and quantization emerge not as fixed primitives, but as harmonic responses to recursive dissonance. The central equation, ψ_total, binds phase and echo in a single recursive field, enabling collapse to be defined and measured without appeal to observer metaphysics. Recursive Harmonics recovers classical mechanics and quantum structure as limiting cases of recursive form, offering a coherent path from Kepler and Newton to Dirac within a single kernel. This preprint outlines the foundational equations culminating in the harmonic atom, explores experimental consequences, and interprets physical instruments as recursive phase manipulators. It suggests a broader architecture in which crisis—whether in particles or in theory—is not noise, but form undergoing change.
