Karanakutuhalam of Bhaskaracarya II: An English Translation with Mathematical Explanation, Derivations, Examples, Tables and Diagrams

Eclipses have remained awe-inspiring events from the remoter past. As a first step in understanding the phenomena, our ancestors studied the movements of sun and moon meticulously. They arrived at the exact calculations that are responsible for the celestial dramas. Their studies were based on strong mathematical foundations which were again based on rational thoughts and logic. When it comes to understanding the techniques they used, especially in the Indian context, we face major difficulties like (i) non-availability of texts; (ii) the available texts are beyond the comprehension of lay persons and even postgraduates in mathematics or physics. These difficulties are fortunately being overcome by the efforts of a small group of schools who are well-versed in mathematics, astronomy and Sanskrit The book under review is one such grand addition to a small list.
