Modern Physics Fundamentals: Quantum Theory and Relativity

Classical physics struggles to explain phenomena at the atomic and cosmic scales. This course provides the foundational knowledge necessary to understand the revolutionary concepts that define modern science. By the end of this course, you will have a strong, conceptual grasp of modern physics principles. You will be able to analyze problems involving wave-particle duality, apply relativistic corrections, and explain the structure and behavior of atoms and nuclei. What you'll learn: * Understand the postulates of special relativity and their consequences for space, time, and mass. * Analyze early quantum phenomena like blackbody radiation, the photoelectric effect, and Compton scattering. * Apply the time-independent Schrödinger equation to simple 1D potential problems to derive energy quantization. * Explain the structure of the atom, including the Bohr model and the role of quantum numbers. * Grasp the conceptual interpretation of wave functions and probability density in quantum mechanics. * Practice solving problems related to nuclear binding energy, radioactivity, and decay processes. The course begins by establishing the limits of classical physics, then transitions into the principles of special relativity and the foundational concepts of quantum theory, concluding with applications in atomic and nuclear physics. This course is designed for absolute beginners in modern physics, including science students or aspiring engineers who have a basic understanding of classical mechanics and calculus. No prior experience with quantum theory or relativity is required. Start reading today to unlock the mysteries of the universe at its most fundamental level.
