Biophysics - the science of physical principles of life itself, of biological systems - is presented here not merely as physics for biologists, but as an entirely independent subject with its own innate network of ideas and approaches. From the microscopic forces that constitute life, the intramolecular bonds and ionic interactions, to the macroscopic forces of the environment, temperature and pressure, the author presents and explains all aspects of life from a Biophysicist's point of view. Exciting biological themes such as neuronal processing and differentiation as well as current medical and environmental topics are introduced from a surprising perspective in this imaginative new textbook.
