Cavendish Professor of Physics the university regulations which allowed students who had not studied at Cambridge to receive a B.A. by submitting a thesis which was judged "of distinction as a record of original research." Among the students attracted by this change was future Cavendish Professor Ernest Rutherford. Whilst Thomson was Cavendish Professor, he discovered the electron and the existence of isotopes, and also fostered an atmosphere of friendliness and mutual helpfulness. Rutherford returned to Cambridge in 1918, and spent the last 19 years of his life there. This was around the time of the change from classical to modern physics, and Rutherford was
Department of Physics, Quaid-e-Azam University It is also a birthplace of "Theoretical Physics Group" (TPG), now shifted to PINSTECH, and invited scientists from all over the world. The department has collaborated with institutes including Kahuta Research Laboratories, National Centre for Physics, Government College University, the International Centre for Theoretical Physics (ICTP) and CERN. Between 1966-1968, Abdus Salam's doctoral students had returned to Pakistan after earning their doctorates and experience. These physicists had been under Abdus Salam's influence and were eager to establish an institute of physics. Abdus Salam enablked them to engage their research in theoretical physics and to establish the country's first school of
