Modern Physics

Modern physics is the branch of physics that deals with the study of phenomena such as the behavior of particles at the atomic and subatomic levels, as well as the behavior of matter and energy at high speeds and very large or very small scales. It includes theories such as quantum mechanics, relativity, and particle physics.

Key Concepts in Modern Physics

1. Quantum Mechanics: The theory that describes the behavior of particles at the atomic and subatomic levels. It introduces the concept of quantized energy levels and wave-particle duality.
2. Special and General Relativity: The theories proposed by Albert Einstein that describe the behavior of matter and energy at high speeds and in the presence of strong gravitational fields.
3. Particle Physics: The study of the fundamental particles and forces that make up the universe, including the Standard Model of particle physics.
4. Nuclear Physics: The study of the properties and behavior of atomic nuclei, including nuclear reactions and radioactivity.
