First Bulletin
(updated 01/31/02)

After Trieste in 1995 and Sarajevo in 1998, the third session of the "FOUR SEAS CONFERENCES" will take place in Thessaloniki (Greece) from
April 16 to April 21, 2002. During this week, students from diverse origins (from every country of South-Eastern Europe, but also from the rest of
the world) will hear about the most recent developments in sciences and technologies.
Topics addressed are : i-) particle physics, ii-) astrophysics and cosmology, iii-) instrumentation with application to medical physics.    

-1- Motivation

Since seven years, the "Four Seas Conferences" are a way to express the solidarity of the scientific community with all those who, under difficult
conditions, seek to keep alive the diverse intellectual and cultural links that constitute the essence of our civilisation. Our efforts are oriented towards
the Balkanic region to promote high level scientific teaching and possibly research, in countries which recently suffered from war and/or dictatorship.

-2- History

"Physique-sans-Frontières" (PSF) was born in 1992, when "ethnic cleansing" in Bosnia was at its worst. Spontaneously, scientists, mainly physicists,
felt the necessity to "do something" in order to show their opposition to barbarity and their solidarity with their colleagues and the people of the region.
Prof. Georges CHARPAK has kindly accepted to preside "Physics-without-Borders / Physique-Sans-Frontières" and supported the effort of the
association to set up the "Four-Seas-Conference" in Trieste. Furthermore, other major personalities in physics (including several Nobel prize winners)
have supported the idea. The Trieste-95 conference was a success, despite the renewed war in Bosnia : 150 physicists, half of them from the South-
Eastern Europe and the other half from the rest of the world, were effectively present. After Trieste, PSF participated in the organisation of "Neutrino-
Sarajevo 96", the first scientific event in Sarajevo just a few weeks after the end of the siege, and, in 1998, the "Sarajevo Summer School", where hundred
students from every part of Bosnia (Bosniacs, Croats and Serbs) and from neibouring countries, enjoyed to work together for the first time after the war.

-3- The Conference in Thessaloniki

After Trieste and Sarajevo, we would like to continue to proceed in the direction of the South-East, to get closer to our colleagues from Albania, Bulgaria,
FYROM, Greece, Kosovo, Moldova, Romania, Serbia, Turkey... Making it easier for them to participate in the meeting, is a way to thank them for
participating in the two previous meetings in Trieste and Sarajevo, despite the distance and adminis-trative problems they had to face. The conference will
be held in Thessalonoki April 16-21, 2002 in the "DIAKONIA" convention centre in Thessaloniki, Greece. It is an ideal location as it allows easy access
from the entire area of south-eastern Europe.

A preliminary version of the Scientific programme of the conference is attached. As usual, it is devided in three parts : Particle Physics, Astrophysics &
Comology, Instrumentation & Applications to Medical Physics. The conference will include 15 sessions of 2 hours each (5 sessions for each part). We
estimate that interdisciplinarity between neighbouring sciences is always useful and fruitful.

-8.2- Accommodation : Participants will have accommodation in the Diakonia Convention Centre. Every room have bathroom and/or shower. There are very
few single rooms. See below the package which will be proposed for registration, some of them including accommodation. Thanks to the generous help from the
sponsors of the conference, participants from South-Eastern European countries may receive a financial support for meals and accommodation in shared rooms.
Following the Trieste tradition, they may also receive a modest amount of money ("per-diem"). After acceptation, they will have to pay the administrative fee of
20 Euro by March 15st (for instance by sending by postmail a Traveller Cheque of 20 € or 20 $ if easier). This amount will be reimbursed at arrival in DCC.
Participants from the European Union are not eligible for this financial support.

-8.3- Transportation

Greece belonging to the "Schengen" European Union system, a visa could be needed to enter the country (please, verify several weeks before the
conference). Contact the secretariat if you need invitation letter. There are several bus services from Serbia, Romania and Bulgaria. There are many flights to
and from Thessaloniki every day, many of them via Athens. The dates of the conference have been chosen to allow use  of low fare tickets (week-end)

Participants from South-Eastern European countries (non-EU) may receive financial assistance for travel. Priority will be given to several participants
sharing the same car for most of the journey. Please contact the conference secretariat to know the amount of money you could be reimbursed. Participants
from the European Union are not eligible for financial support for travel expenses.

Your Arrival  :

-a- Courtesy bus on Monday April 15 :

Departure time Departure place arrival
19:30 Airport (arrivals) to DIAKONIA
20:30 Railways station to DIAKONIA
23:45 Airport (arrivals) to DIAKONIA
~ 24:00 Railways station to DIAKONIA

Important note: due to the courtesy bus  offer (free of charge), there will be no reimbursment of taxis on Monday and the days before.

-b- Taxis (at any time) : No more than 8 -10 Euros to go to Diakonia (65 Nikolaou PLASTIRA Street) from Airport.

-c- City bus The bus No 78 is going from the airport to the railways station from 5:25 in the morning until 23:35 PM. The frequency is every 25 min an the duration is
about 35 min. The ticket price is 0.90 Euro and you can buy tickets from a tobacco store, there is one in the airport in departure department
From the railways station, you can take the bus #11 to reach DIAKONIA (stop in the middle of Nikolaou Plastira street). The price for the bus ticket inside the city is 0.44 Euro
and you can buy from the tobaccos store (you will rapidly discover that there are plenty of tobaccos stores in the streets of any greek city !)

* Tuesday Night : it is foreseen to have a tour of Thessalonik and/or reception by the Rector of the Thessaloniki University.

* Thursday will be fully devoted to Social Programme which will include visits of the most famous Ancient Macedonian Royal Cities of Verginia and Pela including the Royal Tombs
of Philip II of Macedonia recently discovered and the native place of Alexander the Great whose the shade is always here ......

* Sunday Morning : to end correctly the conference, we will visit the Archeological Museum of Thessaloniki (where  are the most important pieces from Pela and Verginia) and/or
the Byzantine Museum.
