Since statistical physics is a tool for the study not only of disordered physical systems, but of biological systems as well, this book from MRS focuses on both. While including physical problems such as fractals, pattern formation at first-order phase transitions, and glassy dynamics, the book also focuses on problems such as the statistical mechanics of DNA and DNA replications, structuring in biological systems, and problems in 'biologically inspired physics'. Topics include: statistical mechanics of proteins; statistical mechanics of DNA; biologically inspired physics; statistical mechanics in biology; micromanipulation in physics and biology; friction and fracture; statistical mechanics in physics and granular media.
