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
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.

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.
This is a list of quantum field theories. The first few sections are organized according to their matter content, that is, the types of fields appearing in the theory. This is just one of many ways to organize quantum field theories, but reflects the way the subject is taught pedagogically.
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.
The branches of science, also referred to as sciences, scientific fields or scientific disciplines, are commonly divided into three major groups: Formal sciences : the study of formal systems , such as those under the branches of logic and mathematics , which use an a priori , as opposed to empirical , methodology .
