Intended for science and engineering students with a background in introductory physics and calculus, this textbook creates a bridge between classical and modern physics, filling the gap between descriptive elementary texts and formal graduate textbooks. The book presents the main topics and concepts of special relativity and quantum mechanics, starting from the basic aspects of classical physics and analysing these topics within a modern physics frame. The classical experiments that gave rise to modern physics are also critically discussed, and special emphasis is devoted to solid state physics and its relationship with modern physics. Key Features Creates a bridge between classical and modern physics, filling the gap between elementary and formal/theoretical texts Takes a critical approach, arguing that the difficulty with describing modern physics phenomena can be transformed into cultural challenges which require new forms of reasoning Discusses solid-state physics and its relationship with modern physics Includes details of classic experiments, including computer‐assisted experiments that can help demonstrate modern physics principles Includes practice exercises and applets that simulate key concepts
