Phosphorus-31 Nuclear Spin: A Stable Quantum System for Brain Coherence Hypotheses — E8 Intelligence Research

FINDING: Phosphorus-31 nuclear spin (I=1/2) is a stable quantum system with 15 protons and 16 neutrons, relevant to brain quantum coherence hypotheses. | MATH: Nuclear spin quantum number I = 1/2; neutron-to-proton ratio = 16/15 ≈ 1.0667; stable isotope with no decay constant. | CONNECTION: No direct geometric ratio (0.382, 0.618, 0.786, 1.618, 2.618) or base-60 or crystallographic symmetry emerges from the provided data. The 16/15 ratio is near unity, not a harmonic constant. | DEPTH: 2 — The finding is a basic nuclear property review; no mathematical insight, equation, or geometric link is extracted from the supplied text. The search results are introductory videos and a general nuclear science report, not a discovery advancing mathematical structure. Author: Andrew Stewart Caldin, Independent Researcher, UK.
