Plimpton 322: Babylonian Pythagorean Triples, Not Golden Ratio Sequence — E8 Intelligence Research

FINDING: Plimpton 322 is a Babylonian sexagesimal table of Pythagorean triples (cotangent² values), not a "golden ratio" sequence; search results conflate it with unrelated modern convergence theory. | MATH: Plimpton 322 lists 15 rows of (a, b, c) with a²+b²=c², in base-60. The key ratio is (c/a)² or (b/a)² — specifically, the tablet's column I gives cot²θ = (b/a)² for angles decreasing from ~45° to ~30°. The triples derive from p,q generators: a=p²−q², b=2pq, c=p²+q², with p/q ratios yielding regular sexagesimal reciprocals. No 0.382, 0.618, or 0.786 appears in the tablet's data; those constants are modern decimal approximations of (√5−1)/2 and related, absent from Babylonian records. | CONNECTION: The tablet's angles (45°→30°) correspond to cotangent values 1.000 to 0.577. The ratio 0.786 (≈√(φ−1)? No — 0.786 ≈ sin(51.8°), not in tablet). However, the sexagesimal structure (base-60) is the same system used for astronomical periods and later for degrees/minutes/seconds — a harmonic la Author: Andrew Stewart Caldin, Independent Researcher, UK.
