In his work "Philosophy and Unified Science," Dr. Talbott has shown that there is a coherent structure within both classical and modern physics, as well as coherent relationships between physics and physical chemistry. Students of physics and chemistry are often confronted with a huge array of seemingly disconnected facts. Applying the "laws of physics" therefore becomes a puzzle of selecting all the relevant and correct facts from this huge array. Dr. Talbott has provided the framework to accomplish this task. It is an invaluable text for the student and the professional alike, as it provides new and unique insight into the interconnected structure of these branches of science, and their relation to the world and universe within which we live.
