Hello Sonia.. His achievements are RCI in hyderabed, Indian Nuclear Program, DRDO, ISRO.. He is the ideal muslim..who indiansed himself and admires the greatness of hindu civilization. Even when he was a kid(i mean even before he was a celebrity), his family are well respected in rameshwaram cos of there true secular attitude. Can you tell me any other muslim who follows islam and still sing and listen GITA and Carnatic music? Apart from this..he was the key behind India's missile and space programmes. He directly worked under Sri.Satish Dhawan, the Pioneer of ISRO. He is an ideal man and ideal leader. Please get yourself a copy of "Ignited Minds" and read it. I bet your attitude towards our country changes..in a very good way. He discusses the problems and he gives the possible solutions like a teacher. One more thing.. Just compare him as anucler scientist with AQ Khan of Pakistan..see what world thinks of him.. I am not saying he is great because he didnt proliferate..but look how sincere and dedicated he is ..
