She has quoted that according to Sir James Braithwaite Peile, Director of National Education in India, Dalvi proved that the great Newton was mistaken from the beginning to the end in his "Rule for Imaginary Square roots" and the application of this Newtonian rule does not bring about the intended result. Sir James Braithwaite Peile also reported that D. A Dalvi blew the theorems of Professor James J Sylvester, one of the greatest English mathematicians, into smithereens. He wrote on Aryan Trigonometry and published in the Theosophist Part 1 1879-1880 how the Ancient Indian Trigonometrical rule for finding sine of an angle long antedates Hipparchus and Hindus before the beginning of the Christian Era, were in possession of the supposed recent trigonometrical discoveries of Euler. He married Shanta Dalvi (née Janwadkar) and had 2 daughters namely Hira and Putala Dalvi and a son Madhusudan. D. Dalvi. His son M. D.
