Mathematical Substance in Historical Documentaries: A Narrow Corpus Analysis — E8 Intelligence Research

FINDING: The corpus spans broad historical surveys and speculative documentaries, but the only mathematically substantive items are the Babylonian/Egyptian documentary and the "Hidden Mathematics" lecture by Randall Carlson. The rest are general overviews or fringe-adjacent. MATH: - Babylonian base-60 (sexagesimal) system: positional notation with 60 as radix, enabling exact fractions (1/2, 1/3, 1/4, 1/5, 1/6) and astronomical calculations (e.g., 360° circle, 60-minute hour). - Egyptian unit fractions (Rhind papyrus style) and the 2/n table — algorithmic decomposition into distinct unit fractions. - Carlson's lecture references Platonic solids, Earth-Moon ratios, and precession cycles — but no verifiable equations beyond standard geometric ratios (e.g., 1.618, 0.618) and the 360° / 60-base division. - The "oldest math text" video (likely Plimpton 322) implies Pythagorean triples — e.g., (3,4,5), (5,12,13) — and possibly a primitive trigonometric table (secant ratios).
