Modern physics has profoundly transformed our understanding of the natural world and has become the foundation for many of today’s most significant technological advancements. Concepts that once appeared purely theoretical—such as quantum mechanics, atomic structure, and particle interactions—now drive innovations in electronics, communication systems, energy technologies, nanotechnology, and biomedical applications. The rapid development of emerging technologies demands a strong conceptual understanding of modern physics principles, making this field increasingly important for students, researchers, and professionals in science and engineering. The book “Modern Physics for Emerging Technologies” has been prepared as a multi-author academic resource with the aim of presenting the core ideas of modern physics in a clear, structured, and application-oriented manner. Each contributing author brings valuable expertise and teaching experience from the field of physics and related disciplines. Their collective efforts have helped shape a comprehensive text that bridges fundamental physical principles with their relevance to modern technological developments. The book is organized into six carefully structured units, designed to guide readers from the fundamental principles of modern physics to their practical applications in emerging technologies. Unit 1: Foundations of Modern Physics introduces the conceptual origins of modern physics.
