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
History of chemical engineering – history of the branch of engineering that deals with physical science (e.g., chemistry and physics), and life sciences (e.g., biology, microbiology and biochemistry) with mathematics and economics, to the process of converting raw materials or chemicals into more useful or valuable forms.
Chemical physics – the branch of physics that studies chemical processes from physics. Computational physics – study and implementation of numerical algorithms to solve problems in physics for which a quantitative theory already exists. Condensed matter physics – the study of the physical properties of condensed phases of matter.
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).
For example, chemistry studies properties, structures, and reactions of matter (chemistry's focus on the molecular and atomic scale distinguishes it from physics). Structures are formed because particles exert electrical forces on each other, properties include physical characteristics of given substances, and reactions are bound by laws of ...
Although physics and chemistry are branches of science that both study matter, they differ in the scopes of their respective subjects. While physics focuses on phenomena such as force, motion, electromagnetism, elementary particles, and spacetime, [3] chemistry is concerned mainly with the structure and reactions of atoms and molecules, but does not necessarily deal with non-baryonic matter.
The term "chemical physics" in its modern sense was first used by the German scientist A. Eucken, who published "A Course in Chemical Physics" in 1930. Prior to this, in 1927, the publication "Electronic Chemistry" by V. N. Kondrat'ev, N. N. Semenov, and Iu. B. Khariton hinted at the meaning of "chemical physics" through its title.
Most disciplines are broken down into (potentially overlapping) branches called sub-disciplines. There is no consensus on how some academic disciplines should be classified (e.g., whether anthropology and linguistics are disciplines of social sciences or fields within the humanities ).
