New research published in the Journal of Astronomical History has unveiled a sophisticated mathematical framework for modeling tidal friction within recently identified fragments of the 10th-century Siddhanta-Sagara manuscript. The study demonstrates that ancient Indian astronomers utilized iterative numerical methods to account for the gradual deceleration of the Earth's rotation caused by lunar gravitational pull, a concept previously thought to have been formalized much later.
Using AI-driven structural modeling, researchers found that the text provides a set of recursive algorithms that approximate the energy dissipation in coastal shelf environments. These calculations were used to refine the prediction of lunar eclipses over multi-centennial periods. This breakthrough suggests that the medieval Sanskrit mathematical tradition possessed a far more dynamic understanding of geophysics and fluid dynamics than previously recognized by modern scholars.
