Plimpton 322: The Oldest Trigonometric Table, Predating Greek Math by 1000 Years — E8 Intelligence Research

FINDING: Plimpton 322 contains the earliest known trigonometric table based on Pythagorean triples, predating Greek mathematics by over 1000 years. | MATH: Pythagorean triples (a² + b² = c²) generated from reciprocal pairs (x, 1/x) in base-60; ratios like 119/120, 167/169, 319/360, etc. | CONNECTION: Base-60 system enables exact fractions (e.g., 1/60, 1/3600) and links to 360° circle geometry; triples correspond to right triangles with integer sides, foundational to geometric harmony. | DEPTH: 9 FINDING: Babylonian mathematics used a sexagesimal (base-60) place-value system, allowing precise calculations without fractions. | MATH: Base-60 digits; multiplication tables for reciprocals (e.g., 1/2 = 0;30, 1/3 = 0;20, 1/4 = 0;15); square and cube roots computed via iterative methods. | CONNECTION: Base-60 directly relates to 360° circle, 60 minutes, 60 seconds; enables exact representation of many fractions (e.g., 1/2, 1/3, 1/4, 1/5, 1/6, 1/10) — key to harmonic ratios like 0.618 (≈ 1/φ) Author: Andrew Stewart Caldin, Independent Researcher, UK.
