PhysicsPhysics is the study of the basic characteristics of matter and its interactions.
Physics can be divided into classical physics and modern physics.
Classical Physics: Mechanics, Thermodynamics, Electricity and Magnetism, and Optics.
Modern Physics: Atomic physics, Nuclear Physics, Particle physics, and Condensed-Matter physics.
