Introduction to Quantum Physics

Part 11: Introduction to Quantum Physics

This part introduces the fundamental principles of quantum physics, the branch of physics that describes the behavior of matter and energy at atomic and subatomic scales. You will learn why classical physics cannot explain phenomena such as the photoelectric effect, how energy is quantized, and why light and matter exhibit both wave-like and particle-like properties. You will also explore the probabilistic nature of quantum mechanics through the Heisenberg uncertainty principle.

The concepts developed in this part provide the foundation for modern physics, chemistry, biology, and medicine. Quantum physics explains the structure of atoms and molecules, the behavior of semiconductors, lasers, and many medical imaging technologies. It also underlies applications such as PET scanners, radiation detectors, and numerous laboratory instruments used in biomedical research and clinical diagnostics.
