Rabin and R. Bruinsma PREFACE A humoristic view of the physics of soft matter, which nevertheless has a ring of truth to it, is that it is an ill-defined subject which deals with ill-condensed matter by ill-defined methods. Although, since the Nobel prize was awarded to Pierre-Gilles de Gennes, this subject can be no longer shrugged-away as "sludge physics" by the physics community, it is still not viewed universally as "main stream" physics. While, at first glance, this may be considered as another example of inertia, a case of the "establishment" against the "newcomer", the roots of this prejudice are much deeper and can be traced back to Roger Bacon's conception about the objectivity of science. All of us would agree with the weaker form of this idea which simply says that the final results of our work should be phrased in an observer-independent way and be communicable to anybody who made the effort to learn this language. There exists, however, a stronger form of this idea according to which the above criteria of "objectivity" and "communicability" apply also to the process of scientific inquiry. The fact that major progress in the physics of soft matter was made in apparent violation of this approach, by applying intuition to problems which appeared to defy rigorous analysis, may explain why many physicists feel somewhat ill-at-ease with this subject. The inadequacy of the notion that one can do physics in a way which can be taught to a computer is particularly clear to those of us who had the privilege to work with Shlomo Alexander. After discussing a scientific problem with Shlomo one quite often feels that Shlomo said something very deep and important but, at the same time, one fails to fully appreciate the connection between the question asked and Shlomo's answer. Only much later, sometimes after one spends weeks and months thinking about the problem, one suddenly grasps the delicate rela tionship between the problem he raised and Shlomo's comments. The reason is that that Shlomo's deep insights are the product of his unique physical intuition. vii We can only speculate on the origins of this intuition: his unusual background as an experimentalist who turned into a high-powered theorist, his superb geometri cal imagination, his deep feeling for symmetry arguments and last, but not least, the breadth of his interests which go far beyond physics (his collaboration with his wife Esther, on economics, is but one example). While the results of Shlomo Alexander's insights can be turned into simple and comprehensible formulas, his intuition and unique way of reasoning belong to the realm of art. This art has enriched us all in a way which makes Shlomo's impact on the physics of soft matter go even beyond his many beautiful works.
