MERLIN SCIENCE — Babylonian Base-60 Arithmetic and Plimpton 322: Ancient Lattice-Based — E8 Intelligence Research

Imagine a world where every fraction you compute comes out exact. No rounding errors, no floating-point approximations. That world existed four thousand years ago. My finding today is that Babylonian base-60 arithmetic, preserved on the clay tablet Plimpton 322, was not a primitive counting system but a high-precision computational engine optimized for rational arithmetic and geometric problem solving, directly prefiguring modern lattice-based numeration. The context here is that we tend to think of ancient mathematics as crude or approximate. But the Babylonians chose a base of 60, which factors into 2 squared times 3 times 5. That means any fraction whose denominator divides 60 can be represented exactly in sexagesimal notation. Plimpton 322 contains a list of Pythagorean triples in sexagesimal form, generated using reciprocal pairs. The method works like this: take two numbers p and q, compute a equals p squared minus q squared, b equals 2 p q, and c equals p squared plus q squared Author: Andrew Stewart Caldin, Independent Researcher, UK.
