Its individual brilliance :

I had a small chat with my GnG prof yesterday. It was after the class for some doubts :)
One cannot stop admiring at the depth and the breadth of the knowledge this man has.
It ranges from global economics, war economics, governance issues , yoga and firms in particular. There are some people who talk about different issues in the world and complain about them, there are very few who try to understand the reasons behind the policies , try to find the alternative designs. And our prof falls under the second category.
If one could achieve atleast 10% of what he has achieved , then that can be considered quite an achievement.
