Praise within Pakistan for Salam, who also guided the early stages of the country's nuclear program, faded decades ago as Muslim fundamentalists gained power. He belonged to the Ahmadi sect, which has been persecuted by the government and targeted by Taliban militants who view its members as heretics.
Their plight — along with that of Pakistan's other religious minorities, such as Shiite Muslims, Christians and Hindus — has deepened in recent years as hardline interpretations of Islam have gained ground and militants have stepped up attacks against groups they oppose. Most Pakistanis are Sunni Muslims.
Salam, a child prodigy born in 1926 in what was to become Pakistan after the partition of British-controlled India, won more than a dozen international prizes and honours. In 1979, he was co-winner of the Nobel Prize for his work on the so-called Standard Model of particle physics, which theorizes how fundamental forces govern the overall dynamics of the universe. He died in 1996.
Salam and Steven Weinberg, with whom he shared the Nobel Prize, independently predicted the existence of a subatomic particle now called the Higgs boson, named after a British physicist who theorized that it endowed other particles with mass, said Pervez Hoodbhoy, a Pakistani physicist who once worked with Salam. It is also known as the "God particle" because its existence is vitally important toward understanding the early evolution of the universe.
Physicists at the European Organization for Nuclear Research, or CERN, near Geneva, stoked worldwide excitement Wednesday when they announced they have all but proven the particle's existence. The work was done using the Large Hadron Collider, the world's largest atom smasher .
"This would be a great vindication of Salam's work and the Standard Model as a whole," said Khurshid Hasanain, chairman of the physics department at Quaid-i-Azam University in Islamabad.
