Mapping Inseparability (MI) Theorem: Interdisciplinary Wings of Science

We prove Mapping Inseparability (MI) Theorem. Let observed state be Z = η + ∆,where η is baseline first principle and ∆ is input-driven deviation.The central result is that inseparability is in-built: neither η alone nor ∆ alone candetermine the observed Z. This is not an assumption but a structural property of thedecomposition. Any attempt to represent Z by only η or only ∆ fails.This 2 → 1 unification has history in science. Newton unified two motions intoone law, Einstein unified light and matter, Abdus Salam unified electromagnetic andweak forces. MI provides the general mathematical condition for when such unificationis necessary — when baseline and deviation must co-exist. Numerical test confirmsZ = η + ∆ with error 2.3 × 10−16.
