The International Union of Pure and Applied Physics (IUPAP) is the only international scientific union which covers all areas of physics. Organized and run by the physics community, most of its members represent identified physics communities in countries or regions around the world.
The IUPAP was established in 1922 in Brussels with 13 Member countries and the first General Assembly was held in 1923 in Paris. It currently has between 50 and 60 active territorial members, as well as several Corporate Associate Members.
The Aims of the Union Are
- Assist in the worldwide development of physics and promote physics as an essential tool for development and sustainability;
- Engage in the strengthening and improvement of physics education, particularly in developing countries;
- Increase diversity and inclusion in physics, enhancing the participation and recognition of women and of people from under-represented groups;
- Foster international cooperation and sponsor suitable international physics meetings;
- Promote the free circulation of scientists and the open access to data;
- Enhance the vital role of early career physicists;
- Strengthen the links with physicists working outside academia and with other scientific communities;
- Uphold openness, honesty and integrity in the practice, application and promotion of physics;
- Promote international agreements on symbols, units, nomenclature and standards.
