Academic career

After receiving his doctorate in 1951, Salam returned to Lahore at the Government College University as a Professor of Mathematics where he remained till 1954. In 1952, he was appointed professor and Chair of the Department of Mathematics at the neighbouring University of the Punjab. In the latter capacity, Salam sought to update the university curriculum, introducing a course in

as a part of the undergraduate curriculum. However, this initiative was soon reverted by the Vice-Chancellor, and Salam decided to teach an evening course in Quantum Mechanics outside the regular curriculum. While Salam enjoyed a mixed popularity in the university, he began to supervise the education of students who were particularly influenced by him. As a result, Riazuddin remained the only student of Salam who had the privilege to study under Salam at the undergraduate and post-graduate level in Lahore, and

. In his early career in Pakistan, Salam was greatly interested in mathematical series and their relation to physics. Salam had played an influential role in the advancement of nuclear physics, but he maintained and dedicated himself to mathematics and theoretical physics and focused Pakistan to do more research in theoretical physics. However, he regarded nuclear physics (nuclear fission and nuclear power) as a non-pioneering part of physics as it had already "happened". Even in Pakistan, Salam was the leading driving force in theoretical physics, with many scientists he continued to influence and encourage to keep their work on theoretical physics. Salam had a prolific research career in theoretical and high-energy physics. Salam had worked on theory of the

theoretical physicist Jogesh Pati. Pati wrote to Salam several times expressing interest to work under Salam's direction, in response to which Salam eventually invited Pati to the ICTP seminar in Pakistan. Salam suggested to Pati that there should be some deep reason why the protons and electrons are so different and yet carry equal but opposite electric charge. Protons are composed of quarks, but the electroweak theory was concerned only with the electrons and neutrinos, with nothing postulated about quarks. If all of nature's ingredients could be brought together in one new symmetry, it might reveal a reason for the various features of these particles and the forces they feel. This led to the development of

, dubbed "violet". Physicists had believed that there were four fundamental forces of nature: the gravitational force, the strong and weak nuclear forces, and the electromagnetic force. Salam had worked on the unification of these forces from 1959 with Glashow and Weinberg. While at Imperial College London, Salam successfully showed that weak nuclear forces are not really different from electromagnetic forces, and two could inter-convert. Salam provided a theory that shows the unification of two fundamental forces of nature, weak nuclear forces and the electromagnetic forces, one into another. Glashow had also formulated the same work, and the theory was combined in 1966. In 1967, Salam proved the electroweak unification theory mathematically, and finally published the papers. For this achievement, Salam, Glashow, and Weinberg were awarded the Nobel Prize in Physics in 1979. The Nobel Prize Foundation paid tribute to the scientists and issued a statement saying: "For their contributions to the theory of the unified weak and electromagnetic interaction between elementary particles, including, inter alia, the prediction of the weak neutral current". Salam took the Nobel Prize medal to the house of his former professor, Anilendra Ganguly, who taught him at the

As late as the 1960s, Salam made an unsuccessful proposal for the establishment of a nuclear fuel reprocessing plant, but it was deferred on economic grounds by Ayub Khan. According to Rehman, Salam's influence in nuclear development was diminished as late as 1974, and he became critical of Bhutto's control over science. But Salam personally did not terminate his connection with the scientists working in the theoretical physics division at PAEC. As early as 1972–73, he had been a great advocate for the atomic bomb project, but subsequently took a stance against it after he fell out with Bhutto over the

In 1973, Salam proposed the idea of establishing an annual college to promote scientific activities in the country to the Chairman of PAEC, Munir Khan, who accepted and fully supported the idea. This led to the establishment of the International Nathiagali Summer College on Physics and Contemporary Needs (INSC), where each year since 1976 scientists from all over the world come to Pakistan to interact with local scientists. The first annual INSC conference was held on advanced particle and nuclear physics. In November 1971, Salam met with

Here, Bhutto entrusted Salam and appointed Munir Khan as Chairman of PAEC, and head of the atomic bomb program, as Salam had supported Khan. A few months after the meeting, Salam, Khan, and Riazuddin, met with Bhutto in his residence where the scientists briefed him about the nuclear weapons program. After the meeting, Salam established the 'Theoretical Physics Group' (TPG) in PAEC. Salam led groundbreaking work at TPG until 1974.

Legacy

Salam's work in Pakistan has been far reaching and regarded as highly influential. He is remembered by his peers and students as the "father of Pakistan's school of Theoretical Physics" as well as Pakistan's science. Salam was a charismatic and iconic figure, a symbol among them of what they were working or researching toward in their fields. His students, fellow scientists and engineers, remembered him as brilliant teacher, and engaging researcher who would also influence others to do the same. The International Centre for Theoretical Physics established by Salam has continued to train scientists from developing countries. Salam founded the Space Research Commission of and was its first director. In 1998, the Government of Pakistan issued a commemorative stamp to honour Salam as part of its "Scientists of Pakistan" series. His alma mater, Government College Lahore, now a university, has the ''Abdus Salam Chair in Physics'' and Abdus Salam School of Mathematical Sciences named after him. ''The Abdus Salam Chair'' was also established in his honour at the Syed Babar Ali School of Science and Engineering in the

My last meeting with Abdus Salam was only three months ago. His disease had taken its toll and he was unable to talk. Yet he understood what was said. I told him about the celebration held in Pakistan on his seventieth birthday. He kept staring at me. He had risen above praise. As I rose to leave he pressed my hand to express his feelings as if he wanted to thank everyone who had said kind words about him. Dr. Abdus Salam had deep love for Pakistan in spite of the fact that he was treated unfairly and indifferently by his own country. It became more and more difficult for him to come to Pakistan and this hurt him deeply. Now he has returned home finally, to rest in peace for ever in the soil that he loved so much. May be in the years to come we will rise above our prejudice and own him and give him, after his death, what we could not when he was alive. We Pakistanis may choose to ignore Dr. Salam, but the world at large will always remember him.
However, Salam's legacy is often ignored in the Pakistani education system despite his achievements. According to the documentary 'Salam: The First ****** Nobel Laureate,' very few young Pakistanis have heard of him, and his name is not mentioned in Pakistani school textbooks. In 2020, a group of students belonging to the State Youth Parliament desecrated an image of Salam that was present at a college in
