Intended for advanced undergraduates and beginning graduate students in biophysics, biological physics, physiology, medical physics, cell biology, and biomedical engineering who have had prior course in physics and in calculus, this text bridges the gap between introductory physics and its application to the life sciences. This third edition adds much new material, including: the circulatoy system, the logistic question, countercurrent transport, nonlinear systems, image formation, and sensory transducers. Among the many topics treated in this wide-ranging book are: forces in the skeletal system; fluid flow, with examples from the circulatory system; the logistic equation; scaling; transport of neutral particles by diffusion and by solvent drag; membranes and osmosis; equipartition of energy in statistical mechanics; the chemical potential and free energy; biological magnetic fieds; membranes and gated channels in membranes; nonlinear phenomena, including biological clocks and chaotic behavior; signal anaysis; detection of weak signals; radiological physics and the use of x-rays in diagnosis and therapy; magnetic resonance imaging. The text includes many problems to test the student\'s understanding, and chapters include useful bibliographies for further reading. Its minimal prerequisites and wide coverage make ideal for self-study, as well as a useful reference for workers in medical and biological research. A solutions manual is available. A volume in the AIP International Series in Basic and Applied Biological Physics. FROM THE REVIEWS: PHYSICS TODAY \"For the professional physicist, the book provides a painless way for gaining a comprehensive view of the successes of biological physics and, for those who teach, adding some enjoyable topics and different problems to their courses at all levels...This book could be used as the basis for an undergraduate course. It is also a comfortable way to put a biological spin on physics applications ordinarily taught in junior- and senior-level courses...The author is very thorough...And he has made a supreme effort to include the most recent research results in a wide variety of naturally occurring physical and physiological phenomena...For the physicist hoping not to be left behind in the current redirection of relevant science, this book is a perfect fit.\"
