LIFE AND ENERGY is a brilliant introduction to the chemistry of life. In this highly lucid guide to the dynamics of modern biology, Isaac Asimov deftly explores the most recent discoveries in this constantly surprising field of inquiry. In the first part, he explains the mechanics of the inanimate world, the significance of energy, work, motion, heat, and chemical reaction. He then uses these concepts in the second half to analyze and explain the latest advances in the study of enzymes, amino acids, proteins and the very processes which constitute life itself. In short, Dr. Asimov's keen examination of biology's current desire to isolate and control the very basis of life--the significance of which promises to revolutionize life itself--becomes a fascinating as well as informative excursion. Illustrated with drawings, charts and diagrams.

This book develops a consistent macroscopic theory of electromagnetism and discusses the relation between circuit theory and field theory. The theory is developed in successive steps from the Lorentz force, the integral form of Maxwell's equations in free space, and suitable macroscopic models of polarized and magnetized matter. Special features * Covers the electromagnetism of moving bodies and the process of electromechanical energy conversion * Introduces a power-series technique for analyzing quasi-static fields and quasi-stationary systems * Emphasizes the synthesis of fields as opposed to the analysis of fields * Presents, in an appendix, the four-dimensional relativistic formulation of macroscopic electrodynamics recently developed by one of the authors (L. J. Chu)

This book develops a consistent macroscopic theory of electromagnetism and discusses the relation between circuit theory and filed theory. The theory is developed in successive steps from the Lorentz force, the integral form of Maxwell's equations in free space, and suitable macroscopic models of polarized and magnetized matter. It covers the electromagnetism of moving bodies and the process of electromechanical energy conversion; introduces a power-series technique for analyzing quasi-static fields and quasi-stationary systems; it emphasizes the synthesis of fields as opposed to the analysis of fields. Presented in an appendix, the reader will also find, the four-dimensional relativistic formulation of macroscopic electrodynamics.
