<human>:  What is the difference between quantum physics and classical physics?
<bot>: The primary difference between quantum physics and classical physics lies in the way they view the behavior of matter and energy. Classical physics views matter and energy as existing in a continuous, deterministic form while quantum physics views matter and energy existing in a discrete, probabilistic form. Classical physics focuses on the macroscopic view of objects, while quantum physics deals with the microscopic level, looking at individual atoms, particles, and forces. Classical physics relies on the laws of classical mechanics, while quantum physics relies on the principles of quantum mechanics.
