In what is perhaps a sign of the growing Islamic extremism in the country, Pakistan’s only Nobel laureate, who helped develop the theoretical framework that led to the apparent discovery of the subatomic “God particle” last week, is being largely scorned in his homeland because of his religious affiliation.Adbus Salam, who died in 1996, was once hailed as a national hero for his pioneering work in physics and his contribution to Pakistan’s nuclear programme. Now his name is stricken from school textbooks because he was a member of the Ahmadi sect that has been persecuted by the government and targeted by Taliban militants, who view them as heretics.
