Henry Cavendish prefiguring thermodynamics. Theoretical physicist Dietrich Belitz concluded that in this work Cavendish "got the nature of heat essentially right." As Cavendish performed his famous density of the Earth experiment in an outbuilding in the garden of his Clapham Common estate, his neighbours would point out the building and tell their children that it was where the world was weighed. In honour of Henry Cavendish's achievements and due to an endowment granted by Henry's relative William Cavendish, 7th Duke of Devonshire, the University of Cambridge's physics laboratory was named the Cavendish Laboratory by James Clerk Maxwell, the first Cavendish Professor of
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
