This constitution establishes the Association of  Physical Societies of the Balkan Countries under the name “BALKAN PHYSICAL UNION “, as a legal entity with a scientific, non-profit character, which will be governed by the following provisions:

  1. The founding name of the Association of Physical Societies is “BALKAN PHYSICAL UNION”.
  2. The seat of the founding Association is Thessaloniki and specifically the Physics Department of Aristotle University of Thessaloniki.
  3. The Association has its own seal, with the title “BALKAN PHYSICAL UNION”

The idea to establish the Balkan Physical Union was first devised and put in motion by Prof A. Milojevic (Yugoslavia) and Prof. I Ursu (Romania) at the VIII Congress of the Union of Yugoslav Societies of Mathematicians, Physicists and Astronomers (UYSMPA), held in Pristina (Yugoslavia) in Nov. 1985 where the proposal was accepted. The first Balkan Physical Union Council meeting was held in Bucharest in 1987, when the Constitution of the BPU was signed by the Balkan National Physical Society delegates from Albania, Bulgaria, Greece, Romania and Yugoslavia and Turkey. The new constitution was adopted in the 1997 Council held in Cluj, Romania. With this constitution, adopted in 27th of May, 2022, the Balkan Physical Union acquires its legal Entity for the first time. 



The Balkan Physical Union (BPU) is a scientific, non-governmental and non-profit Association of the National Physical Societies of the Balkan Countries, established with the aim to promote:

  • research in physics and related sciences in the Balkans;
  • teaching of physics at the primary, secondary and high school level, and in the universities;
  • application of physics research in industry, economy and environment;
  • collaboration and mutual assistance in research and education among physicists in Balkans and
  • peace and friendship among the Balkan people.


To accomplish the aims outlined in Article 2 of the present Constitution, the BPU may organise:

  • activities within the framework of joint research projects, including mutual assistance, if so desired, in the development and application of research equipment;
  • common research Institutes and Centres;
  • congresses, conferences, symposia, workshops, working groups of experts and other scientific meetings gathering physicists from the Balkan Countries;
  • courses and/or schools with the participation of visiting lecturers to deliver talks and other interactive debates aimed at upgrading the qualification of the professional physicists and the students enrolled in Physics study programmes from the Balkan countries;
  • Olympiads (Balkaniads) in Physics;
  • exchange of students enrolled in Physics study programmes;
  • scientific and science-organisational internships, visits of delegations, acceptance of participants in various events;
  • exchange of scientific and professional information, publications, curricula and syllabi in Physics, devices for demonstration and other training tools;
  • issues of periodical and non-periodical publications, books, monographs, brochures;
  • translation of monographs, textbooks and review publications for acquaintance with the problems and the achievements of the Physicists from the Balkan countries;
  • other joint activities and events involving keen physicists from the Balkan countries, in compliance with the aims stipulated under Article 2.


BPU co-operates with its Members and Associated Members, with the international scientific organisations such as EPS, IUPAP, UNESCO, ICTP, CERN, etc. as well as with scientific societies in other countries that can contribute to the fulfilment of the BPU’s mission.

By Council decision, BPU may issue its own periodical and non periodical publications. For editing them, the Council elects an Editor in Chief and an Editorial Board. The Editor in Chief of the Board reports to the Council.

By Council or Executive Committee decision BPU Institutes or Centres may be formed. Directors of BPU Institutes and Centres report to the Council.

ARTICLE 5: Members of the Association

The members of BPU can be regular, honorary or associate.



Regular members of the BPU are the National Physical Societies of Balkan Countries (Albania, Bulgaria, Cyprus, Greece, Montenegro, Moldova, North Macedonia, Romania, Serbia and Turkey), and one person appointed by each society.

Each Country is represented by only one physical society. The Members of the BPU enjoy equal rights in its activities and administration.

The number of members cannot be less than ten (10). Apart from that it is not subject to any other restriction.

A new society can be accepted following the procedure described as follows:

The candidate society can apply any time to join BPU, but at least 3 months before the Council Meeting. The application form has to be submitted to the BPU President, and then the BPU Executive Committee evaluates the application and makes a proposal in the next Council meeting. 



Honorary members are individuals with highest standing in the field of Physics or supporting organisations that have made significant contributions to support the goals of the BPU. Admission of Honorary Members may be proposed by any BPU member. Honorary members are accepted by a decision of the Council adopted by an absolute majority, following a proposal submitted by the Executive Committee.


Associate Members of BPU are institutions, organisations, and companies working in the field of Physics and Applied Sciences that adopt the goals of BPU and promote and support its activities. Admission of the Associated Members may be proposed by any BPU member.

Associate members are accepted by a decision of the Council adopted by an absolute majority, following a proposal submitted by the Executive Committee.

ARTICLE 9:  Members rights
