FINDING: Microtubule quantum coherence evidence suggests orchestrated objective reduction (Orch-OR) may have measurable physical basis, but current public-domain evidence is largely simulation and theoretical, not experimental confirmation. | MATH: No explicit equations in the provided sources; core theoretical framework (Penrose-Hameroff) invokes quantum superposition timescale τ ≈ ħ/E_G where E_G is gravitational self-energy (Penrose's E_G ≈ (1/2)G∫∫[ρ(r)ρ(r')−ρ(r)ρ_shift(r')]/|r−r'| d³r d³r'); microtubule lattice geometry is a hexagonal (6-fold) tubular arrangement of tubulin dimers, each dimer ~8 nm pitch, 13 protofilaments (Fibonacci-adjacent 13), with possible quantum beat frequencies in GHz–THz range from aromatic ring π-electron delocalization. | CONNECTION: **Strong geometric resonance**: 13 protofilaments (Fibonacci number, ratio 13/8 = 1.625 ≈ φ=1.618); hexagonal packing (crystallographic point group 6/mmm, root system A₂); tubulin dimer spacing ~8 nm and 13-fold symmetry yi Author: Andrew Stewart Caldin, Independent Researcher, UK.
