Physics of the Human Body

This book comprehensively addresses the physics and engineering aspects of human physiology by using and building on first-year college physics and mathematics. Topics include the mechanics of the static body and the body in motion, the mechanical properties of the body, muscles in the body, the energetics of body metabolism, fluid flow in the cardiovascular and respiratory systems, the acoustics of sound waves in speaking and hearing, vision and the optics of the eye, the electrical properties of the body, and the basic engineering principles of feedback and control in regulating all aspects of function. The goal of this text is to clearly explain the physics issues concerning the human body, in part by developing and then using simple and subsequently more refined models of the macrophysics of the human body. Many chapters include a brief review of the underlying physics. There are problems at the end of each chapter; solutions to selected problems are also provided. This second edition enhances the treatments of the physics of motion, sports, and diseases and disorders, and integrates discussions of these topics as they appear throughout the book. Also, it briefly addresses physical measurements of and in the body, and offers a broader selection of problems, which, as in the first edition, are geared to a range of student levels. This text is geared to undergraduates interested in physics, medical applications of physics, quantitative physiology, medicine, and biomedical engineering.

About the Author

Irving P. Herman is Professor of Applied Physics in the Department of Applied Physics and Applied Mathematics at Columbia University in New York, NY. He received B.S. and Ph.D degrees in physics from MIT, where he was a Fannie and John Hertz Predoctoral Research Fellow. He then joined the Lawrence Livermore National Laboratory, which he left in 1986 to join Columbia University. His main research areas have evolved from using lasers for separating deuterium and tritium isotopes, to following and inducing thin-film reactions, and, more recently, to analyzing nanomaterials, and also investigates the guided assembly of nanomaterials. He is a fellow of the American Physical Society and the Optical Society of America, held the Lady Davis Fellowship Visiting Professorship at Hebrew University, and was the Seidman Family Series Lecturer at the Technion. He was chair of his department for six years and director of the National Science Foundation MRSEC Center for Nanostructured Materials at Columbia for 12 years. He has also authored the monograph Optical Diagnostics for Thin Film Processing and over 150 papers in peer reviewed journals, and has three patents.
