Few-Body Problems in Physics '95 : In memoriam Professor Paul Urban

The fifteenth European Conference on Few-Body Problems in Physics has taken place during the week of June 5th to 9th, in the lovely village of Peniscola, approximately midway between Barcelona and Valencia on the Mediterranean coast. This conference continues the tradition initiated in 1972 at Budapest, where the first conference took place, and followed in Graz (1973), Tiibingen (1975), Vlieland (1976), Uppsala (1977), Dubna (1979), Sesimbra (1980), Fer­ rara (1981), Tbilisi (1984), Fontevraud (1987), Uzhgorod (1990), Elba (1991) and Amsterdam (1993). During this week, a total of one hundred and fifty one scientist were exchang­ ing their knowledge and initiatives in this broad field of Few-Body Physics. Even if the name of the conference restricts its domain to Europe, there has been an important participation of scientists from non-European countries. A conference with more than twenty years of tradition is already an au­ tonomous being, with a noticeable inertia. Nevertheless, it is a reasonable thought to bend this inertia trying to introduce some innovation, of course, without any damage to the basic structure and objectives of the conference.
