not yet rated|write a review
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 textdeals 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 forstudents 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.

Editorial Reviews

"Edmonds (The Clarendon Laboratory, U. of Oxford) offers this textbook to help biologists master the theory of electro-magnetic forces. Ten chapters explain the basic theory in a manner accessible to non-physics students, using an approach more descriptive and less dependent on algebraic manipulation than that of most physics textbooks. Essential mathematical concepts are explained for readers lacking a strong mathematical background. Six additional chapters demonstrate the application of the theory for chemistry and biology students. 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."--SciTech Book News
