History of Theoretical Physics · ICTP Trieste
The Dirac Medal of ICTP
Theoretical physics through the lens of one of its most prestigious annual honours — awarded each 8 August in Trieste, on the birthday of Paul Adrien Maurice Dirac.
About This Course
The Dirac Medal of the International Centre for Theoretical Physics (ICTP) was established in 1985 by ICTP’s founding director Abdus Salam, in honour of the centenary of quantum mechanics and the work of Paul Dirac. It is awarded each year on 8 August — Dirac’s birthday — to theoretical physicists for outstanding contributions, and is widely regarded, alongside the Wolf Prize and the Boltzmann Medal, as one of the great lifetime honours in theoretical physics.
The first medals (1985) went to Yakov Zeldovich and Edward Witten. Subsequent laureates form a who’s-who of late-20th and early-21st-century theoretical physics. ICTP records the medallists’ lectures: this course collects 14 of those lectures (28 video parts in total), organised into three thematic modules alongside a foundational module on Dirac himself and the ICTP institution.
