Quantum Mechanics: The Behavior of Matter at Subatomic Level

Quantum mechanics is a branch of physics that deals with the behavior of matter and light on a subatomic and atomic level. It describes the probabilistic nature of particles and the inherent uncertainty in measuring their position and velocity simultaneously. The double slit experiment demonstrates the peculiar behavior of quantum particles, where they can exhibit wave-like properties and interfere with themselves. The observer effect also plays a role in quantum mechanics, as the act of measurement can affect the behavior of particles. Despite its abstract and counterintuitive nature, quantum mechanics is a highly successful scientific theory that explains a wide range of phenomena.
