ψ⁸ / PopΨ: From Equation to Light — Illustrated Architecture of Retentive Difference

This paper presents ψ⁸ / PopΨ, a unified framework linking physics, ethics, and aesthetics through the principle of retentive difference. It introduces a verifiable Lagrangian structure describing how form, light, and meaning can persist beyond ordinary temporal and spatial limits. The study also includes a10 visual components — The Lantern Cycle — ten original illustrations that translate theoretical ψ⁸ structures into visible fields of equilibrium. Together, they demonstrate the continuity between mathematical formulation and aesthetic presence — from equation to light. ψ⁸ thus proposes an illustrated architecture of retention, where science and art converge into a single field of coherence.
