Reference excerpt

The International Union of Pure and Applied Physics (IUPAP; ) is an international non-governmental organization whose mission is to assist in the worldwide development of physics, to foster international cooperation in physics, and to help in the application of physics toward solving problems of concern to humanity. It was established in 1922 and the first General Assembly was held in 1923 in Paris. The Union is domiciled in Geneva, Switzerland. IUPAP carries out this mission by: sponsoring international meetings; fostering communications and publications; encouraging research and education; fostering the free circulation of scientists; promoting international agreements on the use of symbols, units, nomenclature and standards; and cooperating with other organizations on disciplinary and interdisciplinary problems.Therefore it is very important . IUPAP is a member of the International Science Council. IUPAP was the lead organization promoting the adoption of the International Year of Basic Sciences for Sustainable Development, which eventually was proclaimed by the 76th session of the United Nations General Assembly 2 December 2021 for 2022.

History In 1919 was formed the International Research Council "was largely through the representatives of the National Academy of Sciences, Washington, and of the Royal Society, London, to coordinate international efforts in the different branches of sciences, under whose aegis international associations or unions in different branches of science could be formed". By this principle, the 1922 General Assembly of the IRC convened at Brussels and a number of physicists present decided that the formation of a Physics Union was imperative. Thirteen countries (Belgium, Canada, Denmark, France, Netherlands, Empire of Japan, Norway, Poland, Spain, Switzerland, United Kingdom, United States, and Union of South Africa) immediately announced their adherence to the new Union. An Executive committee was formed which undertook to prepare rules, regulations, and activities of the organization. The committee consisted of ten distinguished physicists: W.H. Bragg, M. Brillouin, O.M. Corbino, M. Knudsen, M. Leblanc, R.A. Millikan, H. Nagaoka, E. Van Aubel, and H. Abraham. The committee had Bragg as President, Van Aubel as Vice-President, and Abraham as Secretary. This was the birth of the International Union of Pure and Applied Physics. The year 2022 marked the centenary of IUPAP, organized and run by the physics communities of the world. In this context, IUPAP sponsored the publication of Globalizing Physics: One Hundred Years of the International Union of Pure and Applied Physics, edited by Roberto Lalli and Jaume Navarro. This anthology brings together contributions to the history of IUPAP since its foundation.

Committees and governance The Union is governed by its General Assembly, which meets every three years. The Council is its top executive body, supervising the activities of the nineteen specialized International Commissions and the four Affiliated Commissions – it typically meets once or twice per year. The Union is composed of Members representing identified physics communities. At present 60 Members adhere to IUPAP. The Members are represented by Liaison Committees. Members of the Council and Commissions are elected by the General Assembly, based on nominations received from Liaison Committees and existing Council and Commission members. The IUPAP specialised Commissions are:

C1. Commission on Policy and Finance C2. Commission on Symbols, Units, Nomenclature, Atomic Masses & Fundamental Constants C3. Commission on Statistical Physics C4. Commission on Astroparticle Physics. The commission was previously known as the Commission on Cosmic Rays. C5. Commission on Low Temperature Physics C6. Commission on Biological Physics C8. Commission on Semiconductors C9. Commission on Magnetism C10. Commission on the Structure and Dynamics of Condensed Matter C11. Commission on Particles and Fields C12. Commission on Nuclear Physics C13. Commission on Physics for Development C14. Commission on Physics Education C15. Commission on Atomic, Molecular, and Optical Physics C16. Commission on Plasma Physics C17. Commission on Laser Physics and Photonics C18. Commission on Mathematical Physics C19. Commission on Astrophysics C20. Commission on Computational Physics The Affiliated Commissions are: AC1. International Commission for Optics AC2. International Commission on General Relativity and Gravitation AC3. International Commission for Acoustics AC4. International Commission on Medical Physics AC5. International Association of Physics Students AC6. History and Philosophy of Physics In addition IUPAP has established a number of Working Groups, among others the International Committee for Future Accelerators (WG1) and Women in Physics (WG5), to provide an overview of important areas of international collaboration in physics.

Worked examples

Example 1 — a first encounter with International Union of Pure and Applied Physics

Start with the simplest possible case. Write down what International Union of Pure and Applied Physics claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to International Union of Pure and Applied Physics before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about International Union of Pure and Applied Physics ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of International Union of Pure and Applied Physics

In research: International Union of Pure and Applied Physics appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses International Union of Pure and Applied Physics in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: International Union of Pure and Applied Physics is common in secondary-school and first-year university syllabi. It links to neighbouring topics International Union of Pure and Applied Physics, International learned societies, International organisations based in Switzerland, so understanding it makes those chapters shorter.
In everyday life: Look for International Union of Pure and Applied Physics outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
