Non-relativistic Quantum Mechanics

Non-relativistic Quantum Mechanics is a framework for understanding the behavior of very small particles, like electrons and photons, in situations where their speeds are much less than the speed of light. It relies on principles like wave-particle duality and uncertainty, allowing us to calculate the probabilities of finding particles in specific states. In contexts like Quantum Electrodynamics (QED), which unites quantum mechanics with electromagnetic interactions, it accounts for how light and matter interact. While less comprehensive than relativistic theories, it effectively describes many atomic and molecular phenomena in everyday physics.
