Regarding Dr. Kalam, I am just asking for a clarification. Duringng his nomination to President-election, Indian express wrote an editorial calling on Dr. kalam to discourage people from using the prefix "Dr.", because, according IE, Kalam never had any Doctorate. He was a techocrat specialising in Ballistics, which included missile technology. Nor was he ever involved with nuclear research or the Pokhran (The scientist involved with Pokhran was Dr. R. Chidambaram).
If that is true why everyone continues to use the "Dr." prefix? Kalam too, has never opposed it. Why?
