Foundations of Modern Physics: Relativity and Quantum Concepts

Classical physics cannot explain phenomena at very high speeds or very small scales. Start your journey into the revolutionary world of Modern Physics, where time dilates, energy is quantized, and particles behave like waves. This text-only course provides a rigorous, conceptual introduction to the revolutionary ideas developed in the 20th century. You will move beyond Newtonian mechanics to grasp the theories of Einstein and Planck, gaining a solid framework for studying advanced topics like particle physics and quantum information science. What you'll learn: * Understand the postulates of Special Relativity and the consequences of spacetime distortion. * Analyze the failures of classical physics, including blackbody radiation and the photoelectric effect. * Master the core principles of quantum mechanics, including wave-particle duality and the uncertainty principle. * Apply models of atomic structure, from the Bohr model to wave mechanics, to explain spectral lines and electron behavior. * Practice calculations involving nuclear stability, radioactive decay, and mass-energy equivalence. * Configure basic concepts related to quantum information, such as superposition and entanglement. The course begins by defining the limitations of classical physics, progresses through Special Relativity, and then dives deep into the development of quantum theory. The final sections cover atomic and nuclear structure, providing a comprehensive view of matter and energy. This course is designed for absolute beginners with no prior specialized knowledge in advanced physics or higher mathematics. If you are curious about the physics that governs the universe beyond everyday experience, this is the perfect starting point. Begin exploring the foundational theories of the modern universe today.
