International Union of Pure and Applied Physics is an international scientific union that promotes the advancement of physics and fosters cooperation among physicists worldwide. It operates through national adhering organizations, scientific commissions, and international conferences to coordinate research, education, and standards across institutions and societies. The Union engages with major scientific bodies and contributes to global initiatives in measurement, accreditation, and policymaking.

History

The Union was founded in 1922 in the aftermath of World War I alongside contemporaries such as International Council for Science, Royal Society, Académie des Sciences, Deutsches Museum and Smithsonian Institution to rebuild international scientific communication. Early figures associated with the Union included representatives connected to Albert Einstein, Marie Curie, Max Planck, Ernest Rutherford and Niels Bohr through national academies like the Académie des Sciences (France), Royal Society of London, Kaiser Wilhelm Society, Italian National Research Council, and National Academy of Sciences (United States). During the interwar period the Union interacted with organizations such as League of Nations, International Labour Organization, International Telecommunication Union, and later engaged with post‑World War II institutions like the United Nations Educational, Scientific and Cultural Organization and International Atomic Energy Agency. The Union’s mid‑20th century expansion paralleled developments at CERN, Brookhaven National Laboratory, Lawrence Berkeley National Laboratory, Fermilab, and collaborations exemplified by the Manhattan Project legacy and the International Geophysical Year. In the late 20th and early 21st centuries the Union coordinated with entities including European Physical Society, American Physical Society, Chinese Physical Society, Russian Academy of Sciences, Indian National Science Academy, Japanese Physical Society, and International Union of Pure and Applied Chemistry on cross‑disciplinary initiatives.

Organization and governance

Governance is conducted through a General Assembly, Executive Council, and elected officers who interact with organizations such as International Science Council, United Nations, World Health Organization, International Committee for Weights and Measures, and regional bodies like the European Commission and African Academy of Sciences. Administrative liaison occurs with national institutions including the National Science Foundation, Deutsche Forschungsgemeinschaft, Japan Society for the Promotion of Science, Conseil National de la Recherche Scientifique, and Chinese Academy of Sciences. Presidents and secretaries have come from universities and laboratories such as University of Cambridge, Harvard University, University of Oxford, Massachusetts Institute of Technology, Princeton University, University of Tokyo, Moscow State University, École Normale Supérieure, and University of California, Berkeley. Committees coordinate with awards committees associated with Nobel Prize, Wolf Prize, Dirac Medal, Maxwell Medal, Boltzmann Medal, Crafoord Prize, and national academies like Royal Swedish Academy of Sciences.

Membership and national adhering organizations

National adhering organizations represent countries through societies and academies such as the Royal Society, American Physical Society, European Physical Society, Institute of Physics (United Kingdom), Deutsche Physikalische Gesellschaft, Chinese Physical Society, Indian Physical Society, Japanese Physical Society, Russian Academy of Sciences, Brazilian Physical Society, Australian Academy of Science, Canadian Association of Physicists, Korean Physical Society, Mexican Academy of Sciences, South African Academy of Science, Turkish Physical Society, and Argentine Physical Society. Membership links also include provincial and institutional partners like École Polytechnique Fédérale de Lausanne, National Institute of Standards and Technology, Max Planck Society, CNRS, CSIC, Consejo Nacional de Ciencia y Tecnología, Conseil supérieur de la recherche scientifique, National Research Council (Canada), Academia Sinica, Polish Academy of Sciences, and Hungarian Academy of Sciences. Through these adhering organizations the Union engages with regional unions such as the European Physical Society, African Physical Society, Asia Pacific Center for Theoretical Physics, and multinational projects like ITER and Square Kilometre Array.

Scientific activities and commissions

The Union sponsors commissions and working groups covering areas linked to institutions such as CERN, European Space Agency, NASA, National Aeronautics and Space Administration, European Southern Observatory, Max Planck Institute for Physics, SLAC National Accelerator Laboratory, Los Alamos National Laboratory, Rutherford Appleton Laboratory, and Institut Laue-Langevin. Commissions address topics related to quantum mechanics developments traced through Niels Bohr Institute, Institute for Advanced Study, Perimeter Institute for Theoretical Physics, Kavli Institute for Theoretical Physics, and collaborations with specialty societies like the Optical Society (OSA), IEEE, American Institute of Physics, Materials Research Society, and International Astronomical Union. The Union contributes to standards via liaison with Bureau International des Poids et Mesures, International Organization for Standardization, International Electrotechnical Commission, and metrology institutions including National Physical Laboratory (UK), Physikalisch-Technische Bundesanstalt, and International Bureau of Weights and Measures.

Congresses, conferences, and awards

Major events organized or endorsed by the Union connect with historic conferences and venues such as Solvay Conference, National Academy of Sciences (USA), Royal Institution, International Conference on High Energy Physics, European Conference on Optics, International Conference on Atomic Physics, International Conference on Plasma Physics, International Conference on Statistical Physics, and meetings at CERN, Brookhaven National Laboratory, KEK, DESY, TRIUMF, Sincrotrone Trieste, and ESRF. The Union confers or endorses awards that intersect with the Nobel Prize in Physics, Max Planck Medal, Dirac Medal, Lorentz Medal, Landau Prize, Marie Curie Awards, Tang Prize, and honors administered together with national societies like the American Physical Society prizes.

Publications and outreach

The Union publishes reports, recommendations, and proceedings in collaboration with publishers and journals such as Physical Review Letters, Nature Physics, Science, Reviews of Modern Physics, Journal of Applied Physics, European Journal of Physics, Physics Today, New Journal of Physics, Annalen der Physik, and Reports on Progress in Physics. Outreach activities include partnerships with educational institutions and programs like International Year of Physics, Global Science Forum, Fizeau Prize initiatives, Science Olympiad, International Physics Olympiad, UNESCO programs, and public engagement through museums and centers including Science Museum (London), Exploratorium, and Cité des Sciences et de l'Industrie.
