In the hoary past, India produced great mathematicians like Arya Bhata and Varaha Mihira. But the greatest one of the present day, is Srinivasa Ramanujam. Even while studying 10th standard he had solved all the theorems of Number theory. In his pre occupation with mathematics, he failed in his 12 th standard examination. Nut his greatness was recognized by a great mathematician of England called Dr.Hardy. Without ever reading any of the research done, Ramanujan had derived all the necessary knowledge of Number Theory himself. Since he insisted on taking bath in the river at winter, Ramanujan died at a very early age.
