Type: preprint
Abstract: FINDING: Babylonian base-60 reciprocal tables enabled systematic rational approximations of irrational ratios via sexagesimal fractions, directly linking to geometric harmony constants. MATH: - Base-60 reciprocals: \( 1/n \) expressed as sexagesimal fraction (e.g., \( 1/2 = 0;30 \), \( 1/3 = 0;20 \), \( 1/4 = 0;15 \), \( 1/5 = 0;12 \), \( 1/6 = 0;10 \)). - Key rational approximations of irrationals: - \( \sqrt{2} \approx 1;24,51,10 \) (sexagesimal) = \( 1 + 24/60 + 51/3600 + 10/216000 = 30547/21600 \approx 1.41421296 \) (error ~0.00006). - \( \pi \approx 3;8,29,44 \) (sexagesimal) = \( 3 + 8/60 + 29/3600 + 44/216000 = 3.141592... \) (error ~0.000001). - Reciprocal pairs: \( n \) and \( 1/n \) in base-60 (e.g., 2 and 30, 3 and 20, 4 and 15, 5 and 12, 6 and 10). - Plimpton 322: Pythagorean triples \( a^2 + b^2 = c^2 \) with \( a/b \) ratios approximating sexagesimal fractions (e.g., \( 119/120 \approx 0;59,30 \)).
