Physical Biology of the Cell Rob Phillips, Jane Kondev, Juliet Theriot Physical Biology of the Cell is a biophysics textbook that explores how the basic tools and insights of physics and mathematics can illuminate the study of molecular and cell biology. Drawing on key examples and seminal experiments from cell biology, the book teaches physical model building through a practical, case study approach, demonstrating how quantitative models derived from basic physical principles can be used to build a more profound, intuitive understanding of cell biology.
