Praise for the prior edition "The author has done a magnificent job... this book is highly recommended for introducing biophysics to the motivated and curious undergraduate student." ―Contemporary Physics "a terrific text ... will enable students to understand the significance of biological parameters through quantitative examples―a modern way of learning biophysics." ―American Journal of Physics "A superb pedagogical textbook... Full-color illustrations aid students in their understanding" ―Midwest Book Review This new edition provides a complete update to the most accessible yet thorough introduction to the physical and quantitative aspects of biological systems and processes involving macromolecules, subcellular structures, and whole cells. It includes two brand new chapters covering experimental techniques, especially atomic force microscopy, complementing the updated coverage of mathematical and computational tools. The authors have also incorporated additions to the multimedia component of video clips and animations, as well as interactive diagrams and graphs.
