Best known outside the scientific community for the Nobel Prize in Physics he won in 1991, Pierre-Gilles de Gennes was exceptional amongst scientists for the breadth and depth of his contributions in multiple fields of physics. He was also much ahead of his time in his desire to break down barriers between scientific disciplines and between fundamental and applied science. He was equally unusual in his willingness to explain the nature and purpose of his work to society at large and to young people in particular. Laurence Pl(r)vert''s fascinating work retraces the influences and experiences that moulded this complex, charismatic, charming and eclectic genius. It follows him from his unconventional childhood on the fringes of the old French aristocracy and in war-divided France, through his glittering school and early scientific career, up to the revolutionary breakthroughs in fields as diverse as superconductivity, liquid crystals, polymers and soft matter, culminating in the final consecration of the Nobel prize. Constructed from exclusive interviews with the physicist himself, his family, friends and colleagues, this biography immerses us in the work and character of a truly remarkable figure, a Renaissance man of the 20th centur

This book, based on lectures given at the Polytechnic of Milan, gives a broad overview of the field of polymer dynamics. In these lectures the aim is to stress the fundamental concepts of the behaviour of polymers without drawing on the more advanced mathematical formalism which often obscures the natural elegance of the subject matter. Professor De Gennes is one of the most distinguished workers in the field of material science. Therefore this book will be welcomed by both the experienced researcher in the area and the interested layman. It will be of particular value to graduate students.

The first stage of the physics of long, flexible chains was pioneered by eminent scientists such as Debye, Kuhn, Kramers, and Flory, who formulated the basic ideas. In recent years, because of the availability of new experimental and theoretical tools, a second stage of the physics of polymers has evolved. In this book, a noted physicist explains the radical changes that have taken place in this exciting and rapidly developing field. Pierre-Gilles de Gennes points out the three developments that have been essential for recent advances in the study of large-scale conformations and motions of flexible polymers in solutions and melts. They are the advent of neutron-scattering experiments on selectively deuterated molecules; the availability of inelastic scattering of laser light, which allows us to study the cooperative motions of the chains; and the discovery of an important relationship between polymer statistics and critical phenomena, leading to many simple scaling laws. Until now, information relating to these advances has not been readily accessible to physical chemists and polymer scientists because of the difficulties in the new theoretical language that has come into use. Professor de Gennes bridges this gap by presenting scaling concepts in terms that will be understandable to students in chemistry and engineering as well as in physics.

The study of capillarity is in the midst of a veritable explosion. What is offered here is not a comprehensive review of the latest research but rather a compendium of principles designed for the undergraduate student and for readers interested in the physics underlying these phenomena.

Enthusiasts look forward to a time when tiny machines reassemble matter and process information with unparalleled power and precision. But is their vision realistic? Where is the science heading? As nanotechnology (a new technology that many believe will transform society in the next one hundred years) rises higher in the news agenda and popular consciousness, there is a real need for a book which discusses clearly the science on which this technology will be based. Whilst it is most easy to simply imagine these tiny machines as scaled-down versions of the macroscopic machines we are all familiar with, the way things behave on small scales is quite different to the way they behave on large scales. Engineering on the nanoscale will use very different principles to those we are used to in our everyday lives, and the materials used in nanotehnology will be soft and mutable, rather than hard and unyielding. "Soft Machines" explains in a lively and very accessible manner why the nanoworld is so different to the macro-world which we are all familiar with. Why does nature engineer things in the way it does, and how can we learn to use these unfamiliar principles to create valuable new materials and artefacts which will have a profound effect on medicine, electronics, energy and the environment in the twenty-first century. With a firmer understanding of the likely relationship between nanotechnology and nature itself, we can gain a much clearer notion of what dangers this powerful technology may potentially pose, as well as come to realise that nanotechnology will have more in common with biology than with conventional engineering.

This new edition of the classic text incorporates the many advances in knowledge about liquid crystals that have taken place since its initial publication in 1974. Entirely new chapters describe the types and properties of liquid crystals in terms of both recently discovered phases and current insight into the nature of local order and isotropic-to-nematic transition. There is an extensive discussion of the symmetrical, macroscopic, dynamic, and defective properties of smectics and columnar phases, with emphasis on order-of-magnitude considerations, all illustrated with numerous descriptions of experimental arrangements. The final chapter is devoted to phase transitions in smectics, including the celebrated analogy between smectic A and superconductors. This new version's topicality and breadth of coverage will ensure that it remains an indispensable guide for researchers and graduate students in mechanics and engineering, and in chemical, solid state, and statistical physics.

This volume contains a selection of important papers by P-G de Gennes (1991 Nobel Prize Winner in Physics) which have had a long-lasting impact on our understanding of condensed matter (solid state physics, liquid crystals, polymers, interfaces, wetting and adhesion). A typical example is the original article on “reptation” of polymer chains. The author has added some “afterthoughts” to the main papers (explaining their successes or weaknesses), and some current views on each special problem. Complex systems (polymers or granular matters, etc) are explained without heavy calculations — using simple scaling laws as the main tool.

On the whole I think that this book can give, especially to a young reader, a certain feeling about the enthusiam and novelty of condensed matter research during the last three decades.” Il Nuovo Saggiatore, 2002 Reviews of the First Edition: “This book collects a series of articles in which problems which had always been thought quite intractable are shown to be solved by simple, but clear thinking. Although the phrase “simple views” is justified by the clarity of de Gennes exposition, the problems had been unresolved for decades and it is a tribute to de Gennes' intuitive skill that he has been able to solve so many problems which are not only deep basic science, but also central in modern technology.” Sam Edwards Univ. Cambridge, UK, 1992 “For amateurs and connoisseurs — interested in physics, chemistry or biology — Pierre-Gilles de Gennes has opened his gentry-style 'cabinet de curiosités'. Miscellaneous products of his inventive industry, including the famous and the unfamous, are brought together in this self-selected collection, accompanied with recent hindsightful remarks of the Nobel laureate.” Gérard Toulouse Ecole Normale Supérieure, France, 1992 “This volume of collected works of Pierre-Gilles de Gennes will be a valuable and stimulating source for many years to come for younger readers and for beginners in the subfields of condensed matter covered in this volume, as well as a useful and compact reference book for all workers in the field.” Helmut R Brand Advanced Materials, 1993
