This symposium marked the 10th anniversary of symposia on synergetics, the first of which was held at Schloss Elmau in 1972. As is now weIl known, these symposia are devoted to the study of the formation of structures in physical systems far from thermal equilibrium, as weIl as in nonphysical systems such as those in biology and sociology. While the first proceedings were published by Teubner Publishing Company in 1973 and the second by North Holland Publishing Company in 1974, the subsequent proceed ings have been published in the Springer Series in Synergetics. I believe that these proceedings give a quite faithful picture of the developments in this new interdisciplinary field over the past decade. As H.J. Queisser recently noted, the prefix "non", which is used quite frequent ly in modern scientific literature in words such as "nonequilibrium", "nonlinear", etc., indicates a new development in scientific thinking. Indeed, this new develop ment was anticipated and given a framework in the introduction of "synergetics" more than a decade ago. As everywhere in science, two main tendencies are visible here. On the one hand, we note the achievement of more and more detailed results, and on the other hand, the development of new unifying ideas. In synergetics the latter is unquestionably the main goal. The Springer Series in Synergetics endeavors to attain this goal in two ways. It provides a forum for interdisciplinary discussion by collecting the relevant detailed experimental and theoretical results, and it presents new con cepts under which the various phenomena can be subsumed. The main objective of synergetics was initially the study of the far-reaching analogies between quite different systems far from thermal equilibrium when they pass from disordered states to ordered states. In such transitions, temporal or spatial structures are created in a self-organized fashion on macroscopic scales. Over the past years, a remarkable confluence of ideas has taken place, and a large number of such transitions, which occur in close analogy with phase transitions of thermal equilibrium, have come to be understood. It soon became apparent that in such systems a hierarchy of various transitions can take place when external conditions are changed. The question of universal features has again arisen, and a whole new cl ass of phenomena, described as chaos, has become a focus of scientific study. By chaos we mean seemingly random motion which is described by deterministic equations. While at the beginning of these studies the randomness of such phenomena was the principal interest, over the past years it has become more and more evident that there are again considerable regu larities to be observed experimentally and to be found mathematically. The dis covery of such regularities has become an intriguing enterprise. In this respect the present volume must be seen in close connection with the previous book pub lished in this series, "Chaos and Order in Nature". The present proceedings also mark another shift of emphasis within the field of synergetics. While the emphasis has thus far been placed on dramatic changes in systems on macroscopic scales, such changes may, of course, also occur on the microscopic level, and I am very pleased to be able to include in these proceedings a paper by M. Eigen on the evolution of biomolecules. In this fascinating field of research, an intimate connection exists between dramatic changes on the micro scopic, molecular level, and changes on the macroscopic, phenotypic level. VI This symposium on synergetics was made possible by a grant from the "Stiftung Volkswagenwerk", Hannover, and I would like to take this opportunity to thank the VW-Foundation for its continued and active support of the synergetics project. I also wish to thank my secretary, Mrs. U. Funke, for her efficient help in organizing this symposium and editing these proceedings. Stuttgart, June 1982 H.

Rep. of Germany Let us briefly recall what the aims of synergetics are. The word "synergetics" is composed of Greek words meaning "working together". Practically all systems can be thought of being composed of individual parts such as atoms, molecules, cells, organs, animals,etc. In most cases the individual parts form an entity which may produce patt~rns, structures, or functions on macroscopic scales. Quite often the total system exhibits new qualities which are not present at the level of the individual parts, and at least in same disciplines the cooperation of the individual parts appears to be meaningful or purposeful. In synergetics we ask the question whether there are general principles which govern the selforganized behavior of such systems. Both in the inanimate and animate world we find numerous kinds of structures such as snowflakes, or patterns like rolls, hexagons, or square patterns in fluids which are heated from below. In chemistry we observe chemical waves, spirals, or chemical turbulence. The formation of patterns like stripes or dots on furs or of rings on butterfly wings has become accessible to modelling by means of certain reaction diffusion equations. A whole class of theories in biology can be now subsumed under this "paradigm"which due to its originator might be called Turing's paradigm. But while in the beginning, processes of cell differentiation leading to macroscopic patterns were in the foreground of interest, the present proceedings contain at least two new aspects. In this contribution Hunding shows how an understanding of mytosis may become possible by use of such concepts and Gierer presents his inter esting ideas how topologically correct connections between sensory organs and the corresponding neuronal net can be established. At a still higher level it seems that we are about to understand the formation öf organs, such as wings and feet of insects. Progress has also been made over the past decade in the understanding of tem poral patterns or functions. A standard example for selfsustained oscillations, i.e .. a temporal structure, is provided by the laser and by many further phenomena dealt wlth by quantum optics and quantum electronics. Important new results are reported in the subsequent contributions by Lugiato, Narducci, Velarde, Brun and others. Selfsustained oscillations may be found in quite different fields also, such as oscillations of rolls in the Taylor instability in fluid dynamics, and oscillating chemical reactions of which the Belousov-Zhabotinsky reaction is but one. Biology provides us with a wealth of rhythms and even brain waves indicate the cooperativity of neurons at a macroscopic level. At this instant one should add a warning, however. Namely higher degree of order does not necessarily imply a higher content of meaning. For instance Figure 1 shows an EEG, where the upper part refers to normal brain activity while the lower part refers to brain waves in epileptic seizures. Using modern scientific language, we are
