New Noble laureate of Indian Origin

Its good to see that Indians or Persons of Indian Origin are awarded one of the highest awards in field of science and Technology.He was quick to denounce that Indians are always obsessed with western awards and don’t get carried away.Again the culprit is our own media.The main questions is why persons from Bengal and Tamilnadu have won more awards compared to other states in India.Are really Tamilians and Bengalis more brilliant than others?.Others in India
who have missed nobel are Surendranath Bose,Ramanujam.
