Physical Biology of the Cell is a textbook for a first course in physical biology or biophysics for undergraduate or graduate students.It maps the huge and complex landscape of cell and molecular biology from the distinct perspective of physical biology.As a key organizing principle, the proximity of topics is based on the physical concepts that unite a given set of biological phenomena.Herein lies the central premise: that the appropriate application of a few fundamental physical models can serve as the foundation of whole bodies of quantitative biological intuition, useful across a wide range of biological problems.The Second Edition features full-color illustrations throughout, two new chapters, a significantly expanded set of end-of-chapter problems, and is available in a variety of formats.
