Pourquoi et comment l’Univers a-t-il commencé ? Pourquoi y a-t-il quelque chose plutôt que rien ? Quelle est la nature de la réalité ? Comment expliquer que les lois naturelles soient aussi finement ajustées ? Et nous, pourquoi donc existons-nous ? Longtemps réservées aux philosophes et aux théologiens, ces interrogations relèvent désormais aussi de la science. C’est ce que montrent ici avec brio et simplicité Stephen Hawking et Leonard Mlodinow, s’appuyant sur les découvertes et les théories les plus récentes, qui ébranlent nos croyances les plus anciennes. Pour eux, inutile d’imaginer un plan, un dessein, un créateur derrière la nature. La science explique bel et bien à elle seule les mystères de l’Univers.

This book is about the methods used for unifying different scientific theories under one all-embracing theory. The process has characterized much of the history of science and is prominent in contemporary physics; the search for a 'theory of everything' involves the same attempt at unification. Margaret Morrison argues that, contrary to popular philosophical views, unification and explanation often have little to do with each other. The mechanisms that facilitate unification are not those that enable us to explain how or why phenomena behave as they do. A feature of this book is an account of many case studies of theory unification in nineteenth- and twentieth-century physics and of how evolution by natural selection and Mendelian genetics were unified into what we now term evolutionary genetics.

In this book, we study theoretical and practical aspects of computing methods for mathematical modelling of nonlinear systems. A number of computing techniques are considered, such as methods of operator approximation with any given accuracy; operator interpolation techniques including a non-Lagrange interpolation; methods of system representation subject to constraints associated with concepts of causality, memory and stationarity; methods of system representation with an accuracy that is the best within a given class of models; methods of covariance matrix estimation;methods for low-rank
