Nilakantha somayaji was an important astronomer-mathematician of the Kerala school of astronomy and mathematics and was the author of the much celebrated astronomical work titled Tantrasamgraha.
This book stresses the necessity and importance of astronomical observations to obtain correct parameters for computations and to develop more and more accurate theories.
It even discounts the role of revealed wisdom and divine intuitions in studying astronomical phenomena.
Jyotirmimamsa is sometimes cited as proof to establish that modern methodologies of scientific investigations were known to ancient and medieval Indians.
[2] Neelkantha Somayaji insisted that computational results should tally with that of observations and astronomical parameters and constants should be revised periodically.
