The 4th General Conference of the Balkan Physical Union (BPU-4) will be held in the town of Veliko Turnovo, Bulgaria, from Tuesday 22 August to Sunday 27 August 2000. All the sessions of the conference will take place at the University of Veliko Turnovo “Sts. Cyril and Methodius”, which is beautifully placed on the hill of Sveta Gora. Veliko Turnovo is the ancient capital of Bulgaria situated in the central part of the country. Its buildings are perched as an amphitheater on both banks of the Yantra river and are strangely mirrored in its waters. Archeological diggings on Tsarevets and Trapesitsa Hills reveal its rich and turbulent past. First founded by the Slaves, the town of Veliko Turnovo became the capital of the Second Bulgarian Kingdom and the main center of commercial and cultural activity. During the National Revival Period Turnovo was a leading town of the struggle for an autonomous Bulgarian Church and political freedom. Today the town of Veliko Turnovo is developing as a major industrial, tourist, cultural, and university center of Bulgaria. The Czech Professor K. Jireček (one of the first researchers in the field of Bulgarian history) called Veliko Turnovo unique, the only one town of its kind in the whole of Europe.
The BPU-4 Conference belongs to a series of triennial general physics conferences organized under the auspices of the Balkan Physical Union (BPU). The previous conferences were organized in Thessaloniki (1991), Ismir (1994), and Cluj-Napoca (1997). The BPU conferences are usually attended by about 800 scientists, educators and engineers involved in research, education and applications of physics.
In the last year of the Second Millennium the 4th BPU Conference is supposed to cover the most important results and trends in the following fields of physics:
- nuclear physics and nuclear energy
- astronomy and astrophysics
- gravitation and cosmology
- atomic and molecular physics
- high-energy physics
- condensed matter physics
- optics and lasers
- plasma physics
- theoretical and mathematical physics
- computer science
- meteorology and geophysics
- environmental physics
- alternative sources of energy
- applied physics
- physics education
- history and philosophy of physics
- In 2000 a Joint European Programme initiated by CERN, ESA and ESO Physics on Stage is started. Physics on Stage has as its main goal a better public understan-ding of physics through new methods of education and popularizing its achievements. See for more details www.estec.esa.nl/outreach/pos (central URL) and, also, www.skyarchive.org/ PoS_2000 (the national URL).
During BPU-4 actions and events will be carried out in the framework of the National Physics on Stage Programme
The Conference is open to all scientists from the Balkan countries. Participants from outside the Balkans are also welcome. Participation of young physicists and students is highly appreciated. A special student session is planned. Both invited and contributed talks will be given. Poster sessions will be organized, too. The Scientific Programme Committee will make selection for the oral and poster presentations.
The Scientific sessions will begin at 1000 on Tuesday 22 August 2000 and finish at 1300 on Sunday 27 August 2000. The language of the Conference will be English. No translation services will be provided. A preliminary list of invited speakers includes:
