4 Preface During the past decade we have witnessed not only an increase in knowledge of the "traditional" biophysical problems, but also an understanding of the molecular basis of various biological phenomena. The principles and methods of biophysics now provide an underpinning of all of the basic biosciences and are the rational language for discussion between scientists of different disciplines. The International School on Biophysics Supramolecular Structure and Function held in Dubrovnik in September 1984 had as its goal to provide comprehensive discussions on a large number of subjects both for younger scientists at the doctoral or postdoctoral level interested in the molecular nature of fundamental biological entities, and for experienced scientists wishing to gain a broader insight into molecular structures and functions. The topics discussed at the School were inter- and intramolecular interactions in biological systems, and the structure, organization, and function of biological macromolecules and supramolecular assemblies. A number of topics were centered around either a biological problem or a physical technique, sometimes giving an unbalanced view of the field under discussion. Some of the topics required previous knowledge of basic biophysical principles, which were then applied to gain greater insight into the molecular functions of diverse supramolecular systems. Although not all the lectures could be prepared for publication in this volume, I hope that it contains valuable up-to-date information on various aspects of the molecular basis of life. I wish to express my gratitude to the authors of this volume, who have contributed to the reader's understanding of biophysical problems, and perhaps provided stimulation for further study. The School was organized by the Yugoslav Biophysical Society, the Croatian Biophysical Society and Ruder B o ~ oinstitute v i c in cooperation with UNESCO, sponsored by the International Union for Pure and Applied Biophysics (IUPAB), together with the Scientific Councils of Croatia and Yugoslavia. Financial aid to the School by these bodies is gratefully acknowledged. Thanks go in particular to the Scientific Councils for enabling the preparation of this volume.
