Behavior of nature at the scale of atoms and subatomic particles
Which field is not based on quantum mechanics?
Classical physics
What can be derived from quantum mechanics as an approximation at the macroscopic scale?
Most theories in classical physics

Study Notes
Quantum Mechanics
- Describes the behavior of matter and energy at the atomic and subatomic level.
Limitations of Classical Physics
- Not applicable to the field of atomic and subatomic physics.
- Classical physics is not sufficient for describing nature at the atomic and subatomic scale.
Approximations of Quantum Mechanics
- At the macroscopic scale, classical mechanics can be derived as an approximation.
Key Differences
- Quantum mechanics differs from classical physics in its probabilistic nature, where the position and momentum of particles are uncertain.
- In classical physics, the position and momentum of particles are precisely known.
