Imagine for a moment that Narendra Modi, not Jawaharlal Nehru, had been India’s prime minister in 1947. What might have today’s India looked like in scientific terms? Instead of being noted for its exceptional space programme (Mangalyaan!) and brilliant string theorists (Ashoke Sen!), India would have become a garbage dump for every kind of crackpot science. Medical research would have concentrated on medicines made from cow urine and cow dung, the celibacy of peacocks would be under intense scrutiny, astrology would be taught in place of astronomy, and instead of teaching actual mathematics there would be Vedic mathematics. As in Pakistan, Darwinian evolution would be considered heretical and destructive of religious faith.
