Quantum Coherence in Microtubules: Preliminary Evidence, Unconfirmed Constants — E8 Intelligence Research

FINDING: Microtubule quantum coherence research suggests the brain may exploit quantum effects (e.g., superposition, entanglement) at physiological temperatures, but current evidence is preliminary and contested; no quantitative equation or constant has been experimentally confirmed. | MATH: No new equations or constants extracted from the listed sources. The only mathematical artifact is the arXiv abstract on cavity QED ground-state quantum beats (second-order correlations, feedback control) — unrelated to microtubules. | CONNECTION: None found in the provided material. No explicit ratios (0.382, 0.618, 0.786, 1.618, 2.618), base-60, or crystallographic symmetries are mentioned. Microtubules are hollow cylinders of tubulin dimers (α/β), often arranged in 13 protofilaments — a 13-fold rotational symmetry (not a crystallographic point group in the strict sense, but a cyclic group C13). This is a lattice-like structure, but no mathematical analysis of its symmetry or any golden-ratio lin Author: Andrew Stewart Caldin, Independent Researcher, UK.
