Physics and Society

This book introduces physics as a way to understand the natural world and its connection to major issues facing society. Rather than emphasizing mathematical problem-solving, it presents core concepts in clear terms suited to liberal arts students and general readers. Physics is shown as an experimental science that explains interactions among matter, energy, and forces, and as a foundation for technologies that shape everyday life. Organized around twelve contemporary questions, the text links basic principles to topics such as energy, climate, medical technology, security, and research funding. Each chapter highlights the scientific background needed to evaluate these issues and includes questions for discussion or written reflection. Cross-references guide readers to appendices that summarize key ideas in mechanics, waves, electricity and magnetism, thermodynamics, and modern physics. This book emphasizes informed, data-based decision-making in a society influenced by science and technology. It is designed for a one-semester conceptual course but can also be used independently by readers seeking to better understand how physics relates to public policy, environmental concerns, and quality of life.
