Mathematical secrets of ancient tablet unlocked after nearly a century of study

Dating from 1,000 years before Pythagoras’s theorem, the Babylonian clay tablet is a trigonometric table more accurate than any today, say researchers

(...) with potential modern application because the base 60 used in calculations by the Babylonians permitted many more accurate fractions than the contemporary base 10.

(...) This is a rare example of the ancient world teaching us something new.

« Notre recherche révèle que Plimpton 322 décrit les formes des triangles à angle droit en utilisant un nouveau type de #trigonométrie basée sur des ratios et non des angles et des cercles« , explique l’un des chercheurs Daniel Mansfield. « C’est un travail mathématique fascinant qui démontre un génie indéniable« .

Babylonians developed trigonometry ’superior’ to modern day version 3,700 years ago

They also beat the Ancient Greeks to it, according to Australian academics

The Ancient Babylonians knew about a form of trigonometry more advanced than the modern-day version – about 1,000 years before its supposed invention by the Ancient Greeks, academics in Australia say.

The astonishing claim is based on a 3,700-year-old clay tablet inscribed with a table of numbers.

Known as Plimpton 322, it is already known to contain evidence that the Babylonians knew Pythagoras’ famous equation for right-angled triangles, long before the Greek philosopher gave his name to it. (...)
