David A. Lavis david.lavis@kcl.ac.uk Address: Department of Mathematics King's College London The Strand London WC2R 2LS, UK   David Lavis is an Emeritus Senior Lecturer in the Department of Mathematics at King's College London (KCL) and a Research Associate in the Centre for Philosophy of Natural and Social Science at the London School of Economics. During his career, which has been mainly based at KCL, he has spent periods of leave as a lecturer at Makerere University, Uganda and as a researcher at the Institut Laue-Langevin, Genoble, France and at the Universities of Waterloo and Manitoba, Canada. His main research work and his extensive publications  have been devoted to the investigation of phase transitions in complex lattice systems using mean-field, renormalization group and transfer matrix methods.  The well-known Bell-Lavis model originated in a paper he wrote with G. M. Bell in 1970, with whom the first two of his three books on the statistical mechanics of lattice systems  were co-authored. More recently he has researched and published papers  on the conceptual foundations of thermodynamics and statistical mechanics with a particular concentration on the relationship between them.Roman Frigg R.P.Frigg@lse.ac.uk Work Address: Department of Philosophy London School of Economics Houghton Street London WC2A 2AE UK England   Roman Frigg is Professor of Philosophy in the Department of Philosophy, Logic and Scientific Method and a permanent visiting professor in the Munich Centre for Mathematical Philosophy of the Ludwig-Maximilians-University Munich. He is the winner of the Friedrich Wilhelm Bessel Research Award of the Alexander von Humboldt Foundation. His research interests lie in general philosophy of science and philosophy of physics. He has published papers on scientific representation, modelling, statistical mechanics, randomness, chaos, climate change, quantum mechanics, complexity, probability, scientific realism, computer simulations, reductionism, confirmation, and the relation between art and science. His research in the philosophy of physics focusses on statistical mechanics and thermodynamics. He is the author the Cambridge Element "Foundations of Statistical Mechanics" and he has published a large number of research papers on various aspects of statistical mechanics.
