Salam's notable achievements include the Pati-Salam model, magnetic photon, vector meson, Grand Unified Theory, 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. Salam heavily contributed to the rise of Pakistani physics within the global physics community. Up until shortly before his death, Salam continued to contribute to physics, and to advocate for the development of science in third-world countries.
