Quantum mechanics is one of the most successful physical theories ever devised. At its core, it describes how matter and energy behave at the smallest scales. Key concepts include wave-particle duality, where particles like electrons act as both waves and particles depending on observation. The Heisenberg Uncertainty Principle states that it's impossible to simultaneously know a particle's exact position and momentum. Schrödinger's equation governs how quantum states evolve over time, providing a mathematical framework for predicting outcomes of measurements.
