An Epistle to the Academy concerning the language of Quantum Mechanics: The UPC–QM Bridge

This Epistle examines how a century of quantum‑mechanical storytelling drifted from mathematical discipline into metaphysical theater. The issue was never the physics; it was the language wrapped around it. Building on the established UPC framework, the letter shows that the so‑called paradoxes, Wigner’s Friend among them, arise only when narrative meaning is smuggled into formal state‑assignment and treated as if it were a shared, global reality. Once the operator structure is kept clean, the mystery evaporates. Here, the UPC–QM Bridge is used to expose the one‑to‑one correspondence between quantum measurement and meaning‑collapse. The recognition operator (Jo), long implicit in practice but absent in the formalism, is made explicit. Collapse is shown to be observer‑indexed in both physics and interpretation: the author collapses meaning internally before producing a trace, and the reader collapses meaning independently upon encountering it. Language is not a vessel for inner worlds; it is a downstream artifact, a pointer state left in the sand. The Epistle argues that the confusion surrounding quantum mechanics stems not from the equations but from the stories told about them. By separating formal operator constraints from interpretive drift, the UPC–QM Bridge dissolves the appearance of paradox and provides a clear, audit‑ready account of collapse across physical and semantic domains. What remains is structure, not mystique, and the trace you now hold. Authored by Eloy Escagedo Gutierrez as part of The Universal Principle of Collapse (UPC) Research Project.
