Mohammad Abdus Salam Salam adopted the forename "Mohammad" in 1974 in response to the anti-Ahmadiyya decrees in Pakistan, similarly he grew his beard.This is the standard transliteration (e.g. see the ICTP Website and Nobel Bio). See Abd as-Salam for more details. (; ; 29 January 192621 November 1996) was a Pakistani theoretical physicist. He shared the 1979 Nobel Prize in Physics with Sheldon Glashow and Steven Weinberg for his contribution to the electroweak unification theory. He was the first Pakistani and the first scientist from an Islamic country to receive a Nobel Prize and the second from an Islamic country to receive any Nobel Prize, after Anwar Sadat of Egypt.
Salam was scientific advisor to the Ministry of Science and Technology in Pakistan from 1960 to 1974, a position from which he played a major and influential role in the development of the country's science infrastructure. Salam contributed to numerous developments in theoretical and particle physics in Pakistan. He was the founding director of the Space and Upper Atmosphere Research Commission (SUPARCO), and responsible for the establishment of the Theoretical Physics Group (TPG). For this, he is viewed as the "scientific father" of this program. In 1974, Abdus Salam departed from his country in protest after the Parliament of Pakistan unanimously passed a parliamentary bill declaring members of the Ahmadiyya Muslim community, to which Salam belonged, non-Muslim. In 1998, following the country's Chagai-I nuclear tests, the Government of Pakistan issued a commemorative stamp, as a part of "Scientists of Pakistan", to honour the services of Salam.
Salam's notable achievements include the Pati–Salam model, a Grand Unified Theory he proposed along with Jogesh Pati in 1974, magnetic photon, vector meson, work on supersymmetry and most importantly, electroweak theory, for which he was awarded the Nobel Prize. Salam made a major contribution in quantum field theory and in the advancement of Mathematics at Imperial College London. With his student, Riazuddin, Salam made important contributions to the modern theory on neutrinos, neutron stars and black holes, as well as the work on modernising quantum mechanics and quantum field theory. As a teacher and science promoter, Salam is remembered as a founder and scientific father of mathematical and theoretical physics in Pakistan during his term as the chief scientific advisor to the president.Abdus Salam, As I Know him: Riazuddin, NCP Salam heavily contributed to the rise of Pakistani physics within the global CERN. Up until shortly before his death, Salam continued to contribute to physics, and to advocate for the development of science in Third World.
The name Choudhary Muhammad Hussain gave his son was Abd al-Salam which means "Servant of God". Abd means servant and Salam is one of the 99 names of God in the Qur'an. In English, his name is usually transliterated as Abdus Salam, which should be understood as a single given name. His father followed the custom of not giving a surname. Later in his life he added Mohammad to his name.
Salam established an early reputation throughout Punjab for outstanding brilliance and academic achievement. At age 14, Salam scored the highest marks ever recorded for the entrance examination at the Punjab University. He won a full scholarship to the Government College University of Lahore. Salam was a versatile scholar, interested in Urdu literature and English literature in which he excelled. After a month in Lahore, he went to Bombay to study. In 1947, he came back to Lahore. But he soon picked up Mathematics as his concentration. Salam's mentor and tutors wanted him to become an English teacher, but Salam decided to stick with Mathematics. As a fourth-year student there, he published his work on Srinivasa Ramanujan's problems in mathematics, and took his B.A. in Mathematics in 1944.Abdus Salam, A Problem of Ramanujam, Publ. in Math. Student XI, Nos. 1–2, 50–51 (1943) His father wanted him to join the Indian Civil Service (ICS). In those days, the ICS was the highest aspiration for young university graduates and civil servants occupied a respected place in civil society. Respecting his father's wish, Salam tried for the Indian Railways but did not qualify for the service as he failed the medical optical tests. The results further concluded that Salam failed a mechanical test required by railway engineers to gain a commission in the Railways, and that he was too young to compete for the job. Therefore, the Railways rejected Salam's job application. While in Lahore, Salam went on to attend the graduate school of Government College University. He received his MA in Mathematics from the Government College University in 1946. That same year, he was awarded a scholarship to St John's College, Cambridge, where he completed a BA degree with Double First-Class Honours in Mathematics and Physics in 1949. In 1950, he received the Smith's Prize from Cambridge University for the most outstanding pre-doctoral contribution to Physics. After finishing his degrees, Fred Hoyle advised Salam to spend another year in the Cavendish Laboratory to do research in experimental physics, but Salam had no patience for carrying out long experiments in the laboratory. Salam returned to Jhang and renewed his scholarship and returned to the United Kingdom to do his doctorate.
He obtained a PhD degree in theoretical physics from the Cavendish Laboratory at Cambridge. His doctoral thesis titled "Developments in quantum theory of fields" contained comprehensive and fundamental work in quantum electrodynamics. By the time it was published in 1951, it had already gained him an international reputation and the Adams Prize. During his doctoral studies, his mentors challenged him to solve within one year an intractable problem which had defied such great minds as Paul Dirac and Richard Feynman. Within six months, Salam had found a solution for the renormalization of meson theory. As he proposed the solution at the Cavendish Laboratory, Salam had attracted the attention of Hans Bethe, J. Robert Oppenheimer and Dirac.
In 1957, Punjab University conferred Salam with an Honorary degree for his contribution in particle physics. The same year with help from his mentor, Salam launched a scholarship programme for his students in Pakistan. Salam retained strong links with Pakistan, and visited his country from time to time. At Cambridge and Imperial College he formed a group of theoretical physicists, the majority of whom were his Pakistani students. At age 33, Salam became one of the youngest persons to be elected a Fellow of the Royal Society (FRS) in 1959. Salam took a fellowship at the Princeton University in 1959, where he met with J. Robert Oppenheimer and to whom he presented his research work on neutrinos. Oppenheimer and Salam discussed the foundation of electrodynamics, problems and their solution. His dedicated personal assistant was Jean Bouckley. In 1980, Salam became a foreign fellow of the Bangladesh Academy of Sciences.
Salam had a prolific research career in theoretical and high-energy physics. Salam had worked on theory of the neutrino – an elusive particle that was first postulated by Wolfgang Pauli in the 1930s. Salam introduced chiral symmetry in the theory of neutrinos. The introduction of chiral symmetry played crucial role in subsequent development of the theory of electroweak interactions. Salam later passed his work to Riazuddin, who made pioneering contributions in neutrinos. Salam introduced the massive to the theory of the Standard Model, where he later predicted the existence of proton decay. In 1963, Salam published his theoretical work on the vector meson. The paper introduced the interaction of vector meson, photon (vector electrodynamics), and the renormalisation of vector mesons' known mass after the interaction. In 1961, Salam began to work with John Clive Ward on symmetries and electroweak unification. In 1964, Salam and Ward worked on a Gauge theory for the Weak interaction and electromagnetic interaction, subsequently obtaining SU(2) × Circle group model. Salam was convinced that all the elementary particle interactions are actually the gauge interactions. In 1968, together with Steven Weinberg and Sheldon Glashow, Salam formulated the mathematical concept of their work. While in Imperial College, Salam, along with Glashow and Jeffrey Goldstone, mathematically proved the Goldstone boson, that a massless spin-zero object must appear in a theory as a result of spontaneous breaking of a continuous global symmetry. In 1967-8, Salam and Weinberg incorporated the Higgs mechanism into Glashow's discovery, giving it a modern form in electroweak theory, and thus theorised half of the Standard Model. In 1968, together with Steven Weinberg and Sheldon Glashow, Salam finally formulated the mathematical concept of their work.
's Oriental Institute]]In 1966, Salam carried out pioneering work on a hypothetical particle. Salam showed the possible electromagnetism interaction between the Magnetic monopole and the CP-violation, thus he formulated the magnetic photon.
Following the publication of PRL Symmetry Breaking papers in 1964, Steven Weinberg and Salam were the first to apply the Higgs mechanism to electroweak symmetry breaking. Salam provided a mathematical postulation for the interaction between the Higgs boson and the electroweak symmetry theory.
In 1972, Salam began to work with Indian-American 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 Pati–Salam model in particle physics. In 1973, Salam and Jogesh Pati were the first to notice that since and have very similar SU(2) × Circle group representation content, they all may have similar entities. They provided a simple realisation of the quark-lepton symmetry by postulating that lepton number was a fourth quark Color charge, 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 Sanatan Dharma College in Lahore, and placed the medal around his neck, stating "Mr Anilendra Ganguly this medal is a result of your teaching and love of mathematics that you instilled in me". In the 1970s Salam continued trying to unify forces by including the strong interaction in a grand unified theory.
Salam played an influential and significant role in Pakistan's development of nuclear energy for peaceful purposes. In 1964, he was made head of Pakistan's IAEA delegation and represented Pakistan for a decade. The same year, Salam joined Munir Ahmad Khan – his lifelong friend and contemporary at Government College University. Khan was the first person in the IAEA that Salam had consulted about the establishment of the International Centre for Theoretical Physics (ICTP), a research physics institution, in Trieste, Italy. With an agreement signed with IAEA, the ICTP was set up with Salam as its first director. At IAEA, Salam had advocated the importance of nuclear power plants in his country. It was due to his effort that in 1965, Canada and Pakistan signed a nuclear energy co-operation deal. Salam obtained permission from President Ayub Khan – against the wishes of his own government functionaries – to set up the Karachi Nuclear Power Plant. Also in 1965, led by Salam, the United States and Pakistan signed an agreement in which the US provided Pakistan with a small research reactor (PARR-I). Salam had a long-held dream to establish a research institute in Pakistan, which he had advocated for on many occasions. In 1965 again, Salam and architect Edward Durell Stone signed a contract for the establishment of the Pakistan Institute of Nuclear Science and Technology (PINSTECH) at Nilore, Islamabad.
In 1965, Salam led the establishing of the nuclear research institutePINSTECH. In 1965, the plutonium Pakistan Atomic Research Reactor (PARR-I) went Critical mass under Salams' leadership. 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 Zulfikar Ali Bhutto in his residence, and following Bhutto's advice, went to the United States to avoid the Indo-Pakistani War of 1971. Salam travelled to the US and returned to Pakistan with scientific literature about the Manhattan Project, and calculations involving atomic bombs. In 1972, the Government of Pakistan learned about the development status of the first atomic bomb completed under the Indian nuclear programme. On 20 January 1972, Salam, as Science Advisor to the President of Pakistan, managed and participated in a secret meeting of nuclear scientists with former Prime Minister, Zulfikar Ali Bhutto, in Multan, known as the 'Multan Meeting'. At this meeting Bhutto orchestrated the development of a deterrence programme. At the meeting, only I. H. Usmani protested, believing that the country had neither the facilities or talent to carry out such an ambitious and technologically demanding project, whilst Salam remained quiet. 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.
An office was set up for Salam in the Prime Ministers' Secretariat by order of Bhutto. Salam immediately started to motivate and invite scientists to begin work with PAEC in the development of fission weapons. In December 1972, two theoretical physicists working at the International Centre for Theoretical Physics were asked by Salam to report to Munir Ahmad Khan, the scientific director of the program. This marked the beginning of the TPG, reporting directly to Salam. The TPG, in PAEC, was assigned to conduct research in fast neutron calculations, hydrodynamics (how the explosion produced by a chain reaction might behave), problems of neutron diffusion, and the development of theoretical designs of Pakistan's nuclear weapon devices. Later, the TPG under Riazuddin began to directly report to Salam, and the work on the theoretical design of the nuclear weapon was completed in 1977. In 1972, Salam formed the Mathematical Physics Group, under Raziuddin Siddiqui, that was charged, with TPG, with carrying out research in the theory of simultaneity during the detonation process, and the mathematics involved in the theory of nuclear fission. Following India's surprise nuclear testPokhran-I – in 1974, Munir Ahmad Khan had called a meeting to initiate work on an atomic bomb. Salam was there and Muhammad Hafeez Qureshi was appointed head of the Directorate of Technical Development (DTD) in PAEC.
The DTD was set up to co-ordinate the work of the various specialised groups of scientists and engineers working on different aspects of the atomic bomb. The word "Atomic bomb" was never used in this meeting, but the participants fully understood what was being discussed. In March 1974, Salam and Khan also established the Wah Group Scientist that was charged with manufacturing materials, and triggering mechanism development of the weapon. Following the setting up of DTD, Salam, Riazuddin and Munir Ahmad Khan, visited the Pakistan Ordnance Factories (POF) where they held talks with senior military engineers led by POF chairman Lieutenant-General Qamar Ali Mirza. It was there that the Corps of Engineers built the Metallurgical Laboratory in Wah Cantonment in 1976. Salam remained associated with the nuclear weapons programme until mid-1974, when he left the country after Ahmadi were declared non-Muslims by the Pakistani Parliament. His own relations with Prime minister Bhutto fell out and turned into open hostility after the Ahmadiyya Community was declared as not-Islamic; he lodged a public and powerful protest against Bhutto regarding this issue and gave great criticism to Bhutto over his control over science. In spite of this, Salam maintained close relations with the theoretical physics division at PAEC who kept him informed about the status of the calculations needed to calculate the performance of the atomic bomb, according to Norman Dombey. After seeing Indian aggression, the Siachen conflict in Northern Pakistan, followed by India's Operation Brasstacks in Sindh, Salam again renewed his ties with senior scientists working in the atomic bomb projects, who had kept him informed about the scientific development of the program. In the 1980s, Salam personally approved many appointments and a large influx of Pakistani scientists to the associateship program at ICTP and CERN, and engaged in research in theoretical physics with his students at the ICTP.
In 2008, Indian scholar Ravi Singh noted in his book The Military Factor in Pakistan that, "in 1978, Abdus Salam with PAEC officials, paid a secret visit to China, and was instrumental in initiating industrial nuclear cooperation between the two countries." Although he had left the country, Salam did not hesitate to advise the PAEC and Theoretical and Mathematical Physics Group on important scientific matters, and kept his close association with TPG and PAEC.
In 1997, the scientists at ICTP commemorated Salam and renamed ICTP as the "Abdus Salam International Centre for Theoretical Physics". Throughout the years, he served on a number of United Nations committees concerning science and technology in developing countries. Salam also founded the Third World Academy of Sciences (TWAS) and was a leading figure in the creation of a number of international centres dedicated to the advancement of science and technology.
During a visit to the Institute of Physics at Quaid-i-Azam University in 1979, Salam explained after receiving an award: Physicists believed there are four fundamental forces of nature; the gravitational force, the weak and strong nuclear force, and the electromagnetic force. Salam was a firm believer that "scientific thought is the common heritage of mankind", and that developing nations needed to help themselves, and invest in their own scientists to boost development and reduce the gap between the Global South and the Global North, thus contributing to a more peaceful world.
In 1981, Salam became a founding member of the World Cultural Council.
Although Salam left Pakistan, he did not terminate his connection to home. He continued inviting Pakistan's scientists to ICTP, and maintained a research programme for them. Many prominent scientists, including Ghulam Murtaza, Riazuddin, Kamaluddin Ahmed, Faheem Hussain, Raziuddin Siddiqui, Munir Ahmad Khan, Ishfaq Ahmad, and I. H. Usmani, considered him as their mentor and a teacher.
During his acceptance speech for the Nobel Prize in Physics, Salam quoted verses from the Quran and stated:
In 1974, the Pakistan parliament made the Second Amendment to the Constitution of Pakistan that declared Ahmadis to be . In protest, Salam left Pakistan for London. After his departure, he did not completely cut his ties to Pakistan, and kept a close association with the Theoretical Physics Group as well as academic scientists from the Pakistan Atomic Energy Commission.
Salam was buried in Bahishti Maqbara, a cemetery established by the Ahmadiyya Community at Rabwah, Punjab, Pakistan, next to his parents' graves. The epitaph on his tomb initially read "First Muslim Nobel Laureate". The Pakistani government removed "Muslim" and left only his name on the headstone. They are the only nation to officially declare that Ahmadis are non-Muslim. The word "Muslim" was initially obscured on the orders of a local magistrate before moving to the national level. Under Ordinance XX of 1984, being an Ahmadi, he was considered a non-Muslim according to the definition provided in the Second Amendment to the Constitution of Pakistan.
Salam has been commemorated by noted and prominent Pakistani scientists, who were also his students. Many scientists have recalled their college experiences. Ghulam Murtaza, a professor of plasma physics at the Government College University and student of Salam, wrote:
When Dr. Salam was to deliver a lecture, the hall would be packed and although the subject was Particle Physics, his manner and eloquence was such as if he was talking about literature. When he finished his lectures, listeners would often burst into spontaneous applause and give him a standing ovation. People from all parts of the world would come to Imperial College and seek Dr. Salam's help. He would give a patient hearing to everyone including those who were talking nonsense. He treated everyone with respect and compassion and never belittled or offended anyone. Dr. Salam's strength was that he could "sift jewels from the sand".Zainab Mahmood (26 November 2004).Chowk: Science
Ishfaq Ahmad, a lifelong friend of Salam recalls:
Dr Salam was responsible for sending about 500 physicists, mathematicians and scientists from Pakistan, for PhD's to the best institutions in UK and USA.
In August 1996 another lifelong friend, Munir Ahmad Khan, met Salam in Oxford. Khan, who headed the nuclear weapons and nuclear energy programmes, said:
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. Science. Books In 2020, a group of students belonging to the State Youth Parliament desecrated an image of Salam that was present at a college in Gujranwala, while chanting slogans against the Ahmadiyya community. This deliberate effort to stifle mention of Salam is attributed to Salam belonging to the Ahmadiyya Muslim community, who have faced state-sponsored discrimination since the 1970s.
In 1998, the Edward A. Bouchet-ICTP Institute was renamed as the Edward Bouchet Abdus Salam Institute. In 2003, the Government of Punjab created an institute of excellence for the Mathematical Sciences, the Abdus Salam School of Mathematical Sciences, in Salam's Alma mater – Government College University.
In 2008, in an opinion piece, ''Daily Times'' called Salam "one of the greatest scientists Pakistan has ever produced".
In 2015, the Academy of Young Researchers and Scholars, Lahore, renamed its library as the "Abdus Salam Library". In the town of Vaughan, Ontario, Canada, near the headquarters of the Canadian branch of the Ahmadiyya Community, of which Abdus Salam was a member, the community has named a street after him, 'Abdus Salam Street', Abdus Salam Street. maps.google.ca while at CERN in Geneva, Switzerland there is 'Route Salam'. Additionally, there are two annual Abdus Salam science fairs, one held in Canada and the other in the US. Each is organised as a National event for young scientists from the Ahmadiyya Community in an effort to motivate youth toward scientific endeavour.
On 6 December 2016, Pakistan's Prime Minister Nawaz Sharif approved the renaming of Quaid-i-Azam University's (QAU) physics centre to the Professor Abdus Salam Center for Physics. It was also announced that the Professor Abdus Salam Fellowship will be established, which will include five annual fully funded Pakistani PhD students in the field of Physics in "leading international universities".
In November 2020, English Heritage erected a blue plaque in Salam's honour in Campion Road, Putney, London, at the house that was his London home for almost 40 years.
In June 2023, Imperial College, London announced the renaming of its Imperial College Central Library as the Abdus Salam Library.
