#Quantum Mechanics

Quantum mechanics is the branch of physics that describes matter and energy at the scale of atoms and subatomic particles — and it does so in ways that defy ordinary intuition. Particles act as both waves and points. Measurement changes outcomes. Two particles can stay linked across any distance. The posts collected under this tag walk through the foundational ideas (wave-particle duality, superposition, the uncertainty principle, entanglement) and the experiments that forced physicists to accept them — without burying the explanation in equations.
