Quantum mechanics is a branch of physics that describes the behavior of particles at the smallest scales, such as atoms and subatomic particles. It introduces the concept of quantized energy levels, wave-particle duality, and probabilistic nature of particles. In quantum mechanics, particles can exist in multiple states simultaneously until measured, and their behavior is governed by mathematical equations known as wave functions. This theory has revolutionized our understanding of the fundamental building blocks of the universe and has led to the development of technologies like quantum computing and quantum cryptography.
