The two basic divisions of physics are classical physics and modern physics. Classical physics deals with the macroscopic world and includes mechanics, thermodynamics, and electromagnetism. Modern physics focuses on the behavior of particles at the atomic and subatomic levels, encompassing quantum mechanics and relativity.
Albert Einstein revolutionized modern physics with his theory of relativity, which fundamentally changed our understanding of time, space, and gravity. His work laid the foundation for many important developments in physics, including the field of quantum mechanics.

The subdivisions of modern physics include quantum mechanics, relativity theory, particle physics, condensed matter physics, and astrophysics/cosmology. Each of these areas focuses on different aspects of the physical world, from the behavior of subatomic particles to the structure of the universe itself.
The main branches of classical physics include: Classical Mechanics Electromagnetism Classical Optics Thermodynamics Fluid mechanics In modern physics, there are a lot of different fields of study including: The Special Theory of Relativity The General Theory of Relativity Quantum Mechanics. Nuclear Particle Physics Solid state physics, incuding semiconductors. Statistical thermodynamics Quantum Electrodynamics (QED) Quantum Chromodynamics (QCD) In Modern Physics, optics and electricity & magnetism have been unified, especially through the use of Special Relativity. [Three of the most important fields of Modern Physics had been left out. I have put them first , second, and third on the list. By definition, these are Modern Physics because they are products of the 20th century. Also, some very important parts of Classical Physics had been left out, such as fluid mechanics.]
