Our understanding of biological functions is rapidly approaching the molecular level. On this scale the only significant forces are electromagnetic, so that ultimately all living processes must be understood in terms of electromagnetic fields and forces. The first part of this unique new text deals with the theory of electromagnetism using a descriptive and geometrical approach suited to students of biology, chemistry, and biochemistry, and including biologically relevant examples where possible. The second part contains biological topics, which can serve as applications of the theory for students of chemistry or biology, or as an introduction to biology for students trained in the physical sciences who wish to migrate to biology. Topics include the properties of water and ions in bulk solution and in narrow pores, the Debye Layer, possible mechanisms for a magnetic animal compass, an electrostatic model of a proton/ion counterport, and the semi-classical theory of nuclear magnetic resonance.
The book conveniently sets out the basic information that forms the back-ground to the physical approach to parts of biology. It would be useful to research workers with biological backgrounds who find they need to understand electrical phenomena at the physical level. Times Higher Education Supplement
