Modern Physics: Foundations of Relativity and Quantum Theory

Classical physics fails to explain phenomena at very high speeds or very small scales. Modern Physics introduces the revolutionary frameworks needed to describe these extreme limits of the universe. This course provides a clear, text-based introduction to the foundational theories of Modern Physics. You will gain a deep conceptual understanding of how relativity and quantum mechanics fundamentally changed our view of reality and paved the way for modern technology. ### What you'll learn * **Understand** the core postulates of special relativity and their implications for space and time. * **Master** the foundational concepts of quantum mechanics, including quantization, wave-particle duality, and the uncertainty principle. * **Analyze** atomic structure, nuclear physics, and the principles governing radioactive decay and nuclear energy. * **Apply** quantum principles to explain the operation of essential modern devices like lasers and semiconductor materials. * **Practice** conceptual problem-solving based on key equations derived from relativistic and quantum frameworks. The course begins by establishing the necessary foundational terminology and definitions. It then progresses through detailed written explanations of special relativity, atomic structure, and the core principles of quantum mechanics, using written examples and conceptual derivations. This course is ideal for absolute beginners who want a conceptual introduction to Modern Physics. No advanced mathematical or physics background is required to start reading. Begin your journey into the fundamental nature of reality today.
