Domains of major fields of physics. Branches of physics include classical mechanics; thermodynamics and statistical mechanics; electromagnetism and photonics; relativity; quantum mechanics, atomic physics, and molecular physics; optics and acoustics; condensed matter physics; high-energy particle physics and nuclear physics; cosmology; and interdisciplinary fields.
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.
Natural science can be divided into two main branches: life science and physical science. Life science is alternatively known as biology, and physical science is subdivided into branches: physics, chemistry, astronomy and Earth science. These branches of natural science may be further divided into more specialized branches (also known as fields).
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 ...
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;
Classical mechanics was traditionally divided into three main branches. Statics is the branch of classical mechanics that is concerned with the analysis of force and torque acting on a physical system that does not experience an acceleration, but rather is in equilibrium with its environment. [3]
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. [49]
The four main branches of physical science are astronomy, physics, chemistry, and the Earth sciences, which include meteorology and geology. There are also a number of others which have become important in the twenty-first such as materials science and computer science.
