Nino Boccara Livres

This book explores the process of modeling complex systems in the widest sense of that term, drawing on examples from such diverse fields as ecology, epidemiology, sociology, seismology, as well as economics. It also provides the mathematical tools for studying the dynamics of these systems. Boccara takes a carefully inductive approach in defining what it means for a system to be "complex" (and at the same time addresses the equally elusive concept of emergent properties). This is the first text on the subject to draw comprehensive conclusions from such a wide range of analogous phenomena.

"Essential Mathematica" teaches advanced undergraduates and graduates how to effectively use Mathematica for solving problems in mathematics and physics. It features concise command instructions and a variety of applications, including quantum mechanics, electrostatics, and public-key encryption, with a focus on detailed examples.

The Second Winter School on the “Physics of Finely Divided Matter” took place at the Centre de Physique des Houches from 25 March to 5 April 1985, uniting experts in gels and porous media. Participants from diverse backgrounds, including chemistry and physics, engaged in discussions about their latest experimental and theoretical findings. While the experimental techniques may appear distinct, the theoretical interpretations align closely, primarily falling into two categories: percolation and aggregation. These concepts are crucial for understanding gel synthesis, packing structures, and flows in porous media, as well as hydrodynamic instabilities like viscous fingering. Another emerging topic explored is the impact of random media on phase transitions, leading to metastable states interpreted through random fields. Key subjects addressed included the structure of gels and porous media, microemulsions, elastic and dielectric properties of ill-connected media, and flow dynamics in porous environments. As these fields rapidly evolve, the proceedings aim to serve as a valuable reference for newcomers to this intriguing area of study.
