astrophysics, the physics in the universe, including the properties and interactions of celestial bodies in astronomy; atmospheric physics is the application of physics to the study of the atmosphere; space physics is the study of plasmas as they occur naturally in the Earth's upper atmosphere (aeronomy) and within the Solar System
Medical Physics – the branch of physics that deals with the application of physics in medicine – such as imaging exams (NMR, PET scans, and so on), radiotherapy and nuclear medicine. Statistical mechanics – the branch of physics which studies any physical system that has a large number of degrees of freedom.
Modern physics is a branch of physics that developed in the early 20th century and onward or branches greatly influenced by early 20th century physics. Notable branches of modern physics include quantum mechanics, special relativity, and general relativity. Classical physics is typically concerned with everyday conditions: speeds are much lower ...
Acoustics – Branch of physics involving mechanical waves – the branch of physics studying the properties of sound. Actinobiology – Study of effects of radiation on living things – synonymous with radiobiology. Adenology – Branch of medicine dealing the endocrine system – study of glands; Aedoeology – science of generative organs.
Physics is a branch of fundamental science (also called basic science). Physics is also called "the fundamental science" because all branches of natural science including chemistry, astronomy, geology, and biology are constrained by laws of physics. [58]
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 .
History of chemical physics – history of the branch of physics that studies chemical processes from the point of view of physics. History of materials science – history of the interdisciplinary field applying the properties of matter to various areas of science and engineering.
The four major domains of modern physics. Classical physics is a group of physics theories that predate modern, more complete, or more widely applicable theories. If a currently accepted theory is considered to be modern, and its introduction represented a major paradigm shift, then the previous theories, or new theories based on the older paradigm, will often be referred to as belonging to ...
