FINDING: Sumerian base-60 (sexagesimal) system enabled advanced trigonometry and square-root algorithms, predating modern methods. | MATH: Base-60 number system; Plimpton 322 tablet contains Pythagorean triples (e. g. , 3-4-5, 5-12-13) and possibly exact sexagesimal ratios for trigonometric functions; iterative square-root formula: \ (x₍+₁ = 12 (xₙ + Sxₙ) \) (Heron's method, likely Sumerian origin). | CONNECTION: Base-60 yields high divisibility (divisors: 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60) — directly related to geometric circle division (360° = 6×60) and harmonic ratios (e. g. , 1/3 = 0. 333. . . , 1/4 = 0. 25, 1/5 = 0. 2, 1/6 ≈ 0. 1667) ; Plimpton 322 ratios approximate 0. 618 (inverse golden ratio) and 1. 618 via Pythagorean triple scaling; iterative square-root method converges to irrationals (e. g. , √2 ≈ 1. 4142) with geometric mean interpretation. | DEPTH: 9 — This is a foundational mathematical structure (sexagesimal) that directly enables precise astronomical calc Author: Andrew Stewart Caldin, Independent Researcher, UK.
