Being highly interested in Mathematics, you should read all my articles on my blog http://www.navagrahastro.blogspot.in. I am also a post graduate in Mathematics/Statistics and from 1964 onwards, I have been a software architect and am still going strong with my research on Mathematics of Astrology.
