<human>:  Can you explain the principles of quantum physics to me?
<bot>: Quantum physics is a branch of physics that studies the behavior of matter and energy on extremely small scales, where particles act both like particles and waves. Quantum physics describes phenomena like light and atoms with theories such as quantum mechanics, wave-particle duality, and entanglement. Some fundamental principles of quantum physics include the uncertainty principle, Heisenberg's law, and the quantization of energy. The uncertainty principle states that it is impossible to know both the position and momentum of a particle at the same time. Heisenberg's law states that the more precisely a particle's position is known, the less precisely its momentum is known. Finally, the quantization of energy states that energy must be absorbed or emitted in small, discrete amounts.
