Domains of major fields of physics Physics is a scientific discipline that seeks to construct and experimentally test theories of the physical universe. These theories vary in their scope and can be organized into several distinct branches, which are outlined in this article.
History of nuclear physics – history of the field of physics that studies the building blocks and interactions of atomic nuclei. History of nuclear fusion – mechanism powering stars and modern weapons of mass destruction. History of electromagnetism – electricity, magnets, and light from radio waves to gamma rays
The branches of science, also referred to as scientific fields, scientific disciplines, or just sciences, can be arbitrarily divided into three major groups: The natural sciences (biology, chemistry, physics, astronomy, and Earth sciences), which study nature in the broadest sense;
An academic discipline or field of study is known as a branch of knowledge. It is taught as an accredited part of higher education . A scholar's discipline is commonly defined and recognized by a university faculty.
This glossary of physics is a list of definitions of terms and concepts relevant to physics, its sub-disciplines, and related fields, including mechanics, materials science, nuclear physics, particle physics, and thermodynamics.
Field theories, mathematical descriptions of how field values change in space and time, are ubiquitous in physics. For instance, the electric field is another rank-1 tensor field, while electrodynamics can be formulated in terms of two interacting vector fields at each point in spacetime, or as a single-rank 2-tensor field.

History of nuclear physics – history of the field of physics that studies the building blocks and interactions of atomic nuclei. History of optics – history of the branch of physics which involves the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it.
Classical physics traditionally includes the fields of mechanics, optics, electricity, magnetism, acoustics and thermodynamics.The term Modern physics is normally used for fields which rely heavily on quantum theory, including quantum mechanics, atomic physics, nuclear physics, particle physics and condensed matter physics.
