This is a sound introduction to bio-chemistry, as an infant science that is making a revolution in our understanding of how our bodies function. This book deals with those "chemicals that control the workings of living tissue" and the catalysts that make other chemicals function. Many of the questions are still unsolved; but the future answers will be built on the knowledge of those "chemicals of life" described here. While the presentation has somewhat the flavor of text book material, it is a text book in the modern sense of direct, undramatized factual data. The audience interested in the subject, and their number is growing, wants it that way.

While many of us understand complex theories of criticism or finance, we cannot explain why the lights go on when we flick a switch or how a radio works. In this reader-friendly, unabridged edition of three of his best-selling books, renowned science writer Isaac Asimov demystifies physics, teaching the fundamentals in a manner easily understood by lay people. Including the complete text of Motion, Sound and Heat, Light, Magnetism and Electricity, and The Electron, Proton and Neutron, this volume will guide you through the evolution of physics from its early Greek beginnings up to the modern theories of the creation of time, space and matter. Each volume relates the tale of the human quest through the ages for answers to the fundamental questions of how the universe works. Told in its historical context, this quest for knowledge is a story of high drama and uncommon valor, when men put their very lives on the line for the sake of scientific truth. 3 Volumes: Motion, Sound & Heat Light, Magnetism & Electricity The Electron, Proton & Neutron
