FINDING: Babylonian base-60 (sexagesimal) system provided superior arithmetic for fractions, astronomy, and complex calculations, enabling precise time and angle measurement still used today. MATH: Base 60 has divisors 1,2,3,4,5,6,10,12,15,20,30,60 → allows exact representation of 1/2, 1/3, 1/4, 1/5, 1/6, 1/10, 1/12, 1/15, 1/20, 1/30, 1/60 as terminating sexagesimal fractions. Key constant: 60 = 2² × 3 × 5. Plimpton 322 tablet contains Pythagorean triples (a² + b² = c²) in sexagesimal, likely used for generating reciprocal pairs (x, 1/x) and solving quadratic equations. Cubic equations from BM 85200 and YBC 4669 show solutions of form x³ + x² = constant, using geometric methods. CONNECTION: Base-60 directly links to geometric harmony: 360° circle = 6 × 60; 60° angle appears in equilateral triangles and hexagonal (6-fold) crystallographic symmetry. Divisors 2,3,5 produce ratios 1/2 (0.5), 1/3 (0.333…), 2/3 (0.666…), 3/5 (0.6), 5/6 (0.833…). The reciprocal pair method generates numbe Author: Andrew Stewart Caldin, Independent Researcher, UK.
