Abdul Kalam is not and was not a scientist. He has only a Diploma in Mechanical Engineering from a Polytechnic. He was an administrator in the Atomic Energy Commission just because he was a Tamil ( they control every scientific organizations in India); then he went to DRDO and wasted more than Rs.7000 Crors and produced nothing. BJP put him for the post of the president just because of Gijarat riot. That does not make him a scientist. That was the reason Indian Institute of Science refused to give him a post as he is not academically qualified for any post of a scientist.
