Essential Modern Physics: Quantum and Relativity

Modern Physics unlocks the secrets of the universe beyond classical mechanics, but its concepts can often seem abstract and complex. This course provides a clear, step-by-step introduction to the theories that define the 20th and 21st centuries. By the end of this course, you will possess a robust theoretical foundation in the core areas of Modern Physics, allowing you to confidently tackle advanced topics in engineering, chemistry, and pure physics. What you'll learn: * Understand the limitations of classical physics and the origins of quantum theory, including the photoelectric effect and blackbody radiation. * Analyze wave-particle duality and the fundamental principles governing the Bohr model of the atom. * Apply the postulates of Special Relativity to calculate time dilation, length contraction, and mass-energy equivalence. * Learn the principles of nuclear structure, radioactivity, and the processes of fission and fusion. * Configure models describing particle interaction and decay using essential conservation laws. * Explore the basic physical mechanisms behind modern technologies such as lasers and semiconductor devices. We begin by establishing the historical context and foundational definitions of quantum theory, progressing through detailed explanations of atomic structure and relativity. The course concludes with an exploration of nuclear physics and practical applications in current technology. This course is designed for absolute beginners in Modern Physics, including students and enthusiasts with a basic understanding of classical mechanics. No prior advanced physics knowledge is required. Start your journey into the fascinating world of subatomic reality today.
