Flexion Chemistry V1.0: Chemical Structure as a Regime of Matter

Flexion Chemistry V1.0 presents a structural interpretation of chemistry as a contingent regime of matter rather than a universal layer of description. The work addresses a foundational gap in classical chemistry: while chemical theories successfully describe reactions, bonds, and transformations, they do not specify the structural conditions under which chemical reasoning itself remains applicable. Flexion Chemistry introduces chemistry as a temporally sustained regime characterized by limited reversibility, historical differentiation, internal structural tension, and bounded viability. The theory is diagnostic rather than predictive. It does not propose new reaction mechanisms, bonding models, or computational methods. Instead, it defines when chemical descriptions are structurally admissible, when they remain coherent, and when they cease to apply despite ongoing physical or chemical processes. Flexion Chemistry positions chemistry between physics and biology as a transitional regime: emerging when historical differentiation becomes admissible and disappearing when structural persistence becomes self-sustaining. By explicitly defining the boundaries of chemical applicability, the work clarifies the conceptual role of chemistry within a unified structural view of matter.
