{wiki=Quantum_mechanics}
Quantum mechanics is a fundamental branch of physics that deals with the behavior of matter and energy at the smallest scales, such as atoms and subatomic particles. It departs significantly from classical mechanics, which describes the motion of macroscopic objects. Here are some key principles and concepts of quantum mechanics: 1. **Wave-Particle Duality**: Particles, such as electrons and photons, exhibit both wave-like and particle-like properties.
