Linguists and mathematicians at the Indian Institute of Technology (IIT) Madras have announced the successful decipherment of a rare palm-leaf manuscript found in a private library in Madurai. Written in the medieval Grantha script, the text contains a series of sophisticated mathematical proofs involving recursive algorithms used to calculate the area of elliptic surfaces—concepts that were previously thought to have emerged centuries later in European mathematics.
The manuscript, titled Nitya-Ganita-Sara, describes a method for approximating complex curves using infinite series of fractional coefficients. Scholarly analysis suggests these mathematical tools were developed to improve the precision of temple architecture and to model the movements of celestial bodies with non-circular orbits, marking a significant milestone in the history of Vedic mathematics and its medieval evolution.
