Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. [1] [2] As one of the founders of the discipline, James Keeler, said, astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space—what they are, rather than where they are", [3] which is studied ...
Applied physics is the application of physics to solve scientific or engineering problems. It is usually considered a bridge or a connection between physics and engineering . "Applied" is distinguished from "pure" by a subtle combination of factors, such as the motivation and attitude of researchers and the nature of the relationship to the ...
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
In China, for example, with the former specializing in nuclear power research (i.e. nuclear engineering), and the latter closer to engineering physics. [5] In some universities and their institutions, an engineering (or applied) physics major is a discipline or specialization within the scope of engineering science, or applied science. [6] [7 ...
The science of matter is also addressed by physics, but while physics takes a more general and fundamental approach, chemistry is more specialized, being concerned by the composition, behavior (or reaction), structure, and properties of matter, as well as the changes it undergoes during chemical reactions.
The science of geodesy has elements of both astrophysics and planetary sciences. The shape of the Earth is to a large extent the result of its rotation, which causes its equatorial bulge , and the competition of geologic processes such as the collision of plates and of vulcanism , resisted by the Earth's gravity field.
An academic discipline or field of study is a branch of knowledge, taught and researched as part of higher education.A scholar's discipline is commonly defined by the university faculties and learned societies to which they belong and the academic journals in which they publish research.
Space physics, also known as space plasma physics, is the study of naturally occurring plasmas within Earth's upper atmosphere and the rest of the Solar System. It includes the topics of aeronomy , aurorae , planetary ionospheres and magnetospheres , radiation belts , and space weather (collectively known as solar-terrestrial physics [ 1 ] ).
