HISTORY OF THE POLISH-CZECH SEMINARS

 

     The idea of regular scientific meetings of physicist involved in studies of ferroelectrics in Poland and Czechoslovakia followed inevitably from the success of first such event in Błażejewko in 1979. The Seminar was organized by collaborating scientists from the Dielectric Department of the Institute of Physics of Czechoslovak Academy of Sciences in Prague and Ferroelectric Lab of the Institute of Molecular Physics of Polish Academy of Sciences in Poznań.

     We decided to organize Seminars on Structural and Ferroelectric Phase Transitions, by turn, in Poland and in Czechoslovakia (now the Czech Republic) to intensify the cooperation between the scientists of neighboring countries. We used to invite also our colleagues from other European countries who we were collaborating with. The Seminars are the forum of presentation of recent results, unconstrained discussions and initiating of common studies. Lectures on general physics are also a custom of these meetings. The Seminars result not only in scientific integration but also in close friendship.
