Scale Invariance and Multiplicative Symmetry Explain Benford's Law — E8 Intelligence Research

FINDING: Scale invariance in natural data generates Benford's law via multiplicative symmetry groups, linking first-digit distribution to logarithmic invariance under scaling transformations. | MATH: Benford's law: P(d) = log₁₀(1 + 1/d) for d=1..9; leading digit 1 occurs ~30.1%, digit 9 ~4.6%. Underlying invariance: P(kx) = P(x) for any scaling factor k, requiring P(x) ∝ 1/x on logarithmic scale. Multiplicative group ℝ⁺ acts transitively on log-space, making Benford's law the unique Haar measure on the multiplicative group of positive reals. | CONNECTION: The logarithmic spacing of Benford's law mirrors the golden ratio's logarithmic spiral (φ = 1.618) and the base-60 sexagesimal system's natural logarithmic divisions. The 30.1% for digit 1 approximates 1/φ² ≈ 0.382, while digit 9 at 4.6% approximates 1/φ⁶ ≈ 0.056 (φ⁶ ≈ 17.944). The scale-invariant group structure aligns with crystallographic scaling symmetries in quasicrystals (e.g., Penrose tilings with φ scaling). | DEPTH: 8 — Conne Author: Andrew Stewart Caldin, Independent Researcher, UK.
