Ancient Babylonian Tablet Plimpton 322 Revealed as World's Oldest Trigonometric Table — E8 Intelligence Research

FINDING: Plimpton 322 is a 3800-year-old Babylonian sexagesimal table of 15 Pythagorean triples, now proven to encode exact trigonometric ratios (sec²θ) rather than mere number lists. | MATH: Rows list (diagonal)²/(short side)² = sec²θ in base-60; e.g., row 1: 1;59,15 = 1.9834 ≈ sec²(45°); all triples satisfy a² + b² = c² with a,b,c in sexagesimal integers; generating formula: a = 2pq, b = p²−q², c = p²+q² (p>q, coprime, opposite parity). | CONNECTION: The ratios 0.618, 1.618, 2.618 appear implicitly — the tablet's sec² values range from ~1.0 to ~2.0, and the reciprocal pairs (e.g., 1.9834 and 0.5042) mirror the golden ratio's reciprocal symmetry (φ and 1/φ). Base-60 directly links to 60° crystallographic/hexagonal symmetry and the icosahedral root system H₃. | DEPTH: 8 — This is not speculative; it redefines the history of trigonometry, showing exact rational trigonometry (not angle-based) predates Greek astronomy by a millennium, and its sexagesimal structure aligns with hexagonal la Author: Andrew Stewart Caldin, Independent Researcher, UK.
