Includes topics such as quantum mechanics, relativity, and atomic physics.
Special Relativity: The theory that describes how time and space are relative to the observer's frame of reference and how this affects the way objects move and interact.
Quantum Mechanics: The study of the behavior of matter and energy at a small scale, such as atoms and subatomic particles, where classical physics laws no longer apply.
Wave-Particle Duality: The concept that particles can have both wave-like and particle-like properties, and that their behavior is described by quantum mechanics.
Atomic Physics: The study of the behavior and properties of atoms, including the structure of the nucleus and the interactions of atoms with electromagnetic radiation.
Nuclear Physics: The study of the properties and behavior of atomic nuclei, including their structure, stability, and decay.
Molecular Physics: The study of the physical properties and behavior of molecules, including their structure, interactions with electromagnetic radiation, and chemical reactions.
Quantum Field Theory: The theoretical framework that combines quantum mechanics and special relativity to describe the behavior of particles and fields at a small scale.
Astrophysics and Cosmology: The study of the properties and behavior of the universe, including galaxies, stars, planets, and other celestial bodies.
General Relativity: The theory that describes the behavior of gravity in terms of the curvature of spacetime caused by the presence of matter and energy.
