Babylonian mathematics is restored to world history

Aryabhata's trigonometric work demonstrates an independent and influential approach to numerical astronomy.

It places Indian mathematical innovation within the longer global development of algorithms and number representation.

Published on 31 March 2010, the paper reviews competing explanations of the Old Babylonian number table.

The tablet contains numerical relations among right-triangle sides more than a millennium before Pythagoras.

Historians debate whether the tablet was a teaching aid, reciprocal table or trigonometric object.

A paper dated 17 September 2011 proposes a culturally plausible reconstruction of the tablet's numerical sequence.

The analysis builds on Babylonian sexagesimal arithmetic rather than assuming modern angle measurement.

The proposed generation method accounts for gaps and suggests how the table might have continued.

The paper illustrates why understanding scribal practices matters when interpreting ancient numerical artifacts.

Published on 4 April 2012, the paper interprets patterned notches on the Central African artifact as a calculating tool.
