Plimpton 322: World's Oldest Trig Table Using Babylonian Base-60 Ratios — E8 Intelligence Research

FINDING: Babylonian tablet Plimpton 322 is the world's oldest known trigonometric table, using base-60 (sexagesimal) ratios rather than angles or circles. | MATH: The tablet lists 15 rows of Pythagorean triples (a² + b² = c²) in sexagesimal notation, with exact ratios b²/(c² - b²) or similar normalized forms. Key constants: 60 (base), 1;24,51,10 (approximation of √2 ≈ 1.41421296), 0;30 (1/2). The triples are generated by a method equivalent to p = 1, q = 0;30, 0;20, etc., producing pairs like (119, 120, 169) and (3367, 3456, 4825). | CONNECTION: Base-60 directly links to geometric harmony — 60 is divisible by 2,3,4,5,6,10,12,15,20,30, enabling exact fractions for common ratios (0.5, 0.333..., 0.25, 0.2, 0.1666...). The triples correspond to right triangles with rational sides, a precursor to the golden ratio (φ ≈ 1.618) though not explicitly present. The tablet's organization suggests a systematic approach to solving quadratic equations and generating integer-sided triangles, which und Author: Andrew Stewart Caldin, Independent Researcher, UK.
