Understanding Modern Physics: Quantum Mechanics and Relativity

Modern physics revolutionized our understanding of the universe, yet its concepts often seem abstract. This course provides a clear, step-by-step introduction to the fundamental ideas that govern energy, matter, and space-time. By the end of this course, you will grasp the foundational concepts of quantum mechanics and relativity, enabling you to interpret phenomena ranging from atomic structure and radiation to the technology behind semiconductors and nuclear power. What you'll learn: * Understand the experimental evidence for quantum theory, including the photoelectric effect and blackbody radiation. * Apply the principles of special relativity, focusing on time dilation and mass-energy equivalence. * Analyze the structure of the atom and interpret atomic spectra using the Bohr model and wave mechanics. * Practice calculating radioactive decay rates and interpreting the processes of nuclear fission and fusion. * Explore the foundational quantum concepts that drive modern semiconductor technology, such as energy bands and doping. The course begins with classical limitations that led to modern physics, progresses through quantum theory and atomic structure, and concludes with an in-depth examination of nuclear physics and its technological applications. This is a purely written course containing detailed explanations and focused practice exercises. This course is designed for absolute beginners or students seeking a solid conceptual foundation in physics. No prior advanced knowledge of calculus or physics is required.
