Definition[ edit ] Physical science can be described as all of the following: A branch of science a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. In natural science, hypotheses must be verified scientifically to be regarded as scientific theory.
Validity, accuracy, and social mechanisms ensuring quality control, such as peer review and repeatability of findings, are amongst the criteria and methods used for this purpose. Natural science can be broken into two main branches: Each of these branches, and all of their sub-branches, are referred to as natural sciences.
Branches of physical science[ edit ] Physics — natural and physical science that involves the study of matter  and its motion through space and time, along with related concepts such as energy and force.
Branches of astronomy Chemistry — studies the composition, structure, properties and change of matter. Branches of chemistry Earth science — all-embracing term referring to the fields of science dealing with planet Earth. Earth science is the study of how the natural environment ecosphere or Earth system works and how it evolved to its current state.
It includes the study of the atmosphere, hydrosphere, lithosphere, and biosphere. Branches of Earth science History of physical science[ edit ] History of physical science — history of the branch of natural science that studies non-living systems, in contrast to the life sciences.
It in turn has many branches, each referred to as a "physical science", together called the "physical sciences". However, the term "physical" creates an unintended, somewhat arbitrary distinction, since many branches of physical science also study biological phenomena organic chemistry, for example.
History of physics — history of the physical science that studies matter and its motion through space-time, and related concepts such as energy and force History of acoustics — history of the study of mechanical waves in solids, liquids, and gases such as vibration and sound History of agrophysics — history of the study of physics applied to agroecosystems History of soil physics — history of the study of soil physical properties and processes.
History of astrophysics — history of the study of the physical aspects of celestial objects History of astronomy — history of the study of the universe beyond Earth, including its formation and development, and the evolution, physics, chemistry, meteorology, and motion of celestial objects such as galaxies, planets, etc.
History of astrodynamics — history of the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other spacecraft. History of astrometry — history of the branch of astronomy that involves precise measurements of the positions and movements of stars and other celestial bodies.
History of cosmology — history of the discipline that deals with the nature of the Universe as a whole. History of extragalactic astronomy — history of the branch of astronomy concerned with objects outside our own Milky Way Galaxy History of galactic astronomy — history of the study of our own Milky Way galaxy and all its contents.
History of physical cosmology — history of the study of the largest-scale structures and dynamics of the universe and is concerned with fundamental questions about its formation and evolution.
History of planetary science — history of the scientific study of planets including Earthmoons, and planetary systems, in particular those of the Solar System and the processes that form them.
History of stellar astronomy — history of the natural science that deals with the study of celestial objects such as stars, planets, comets, nebulae, star clusters and galaxies and phenomena that originate outside the atmosphere of Earth such as cosmic background radiation History of atmospheric physics — history of the study of the application of physics to the atmosphere History of atomic, molecular, and optical physics — history of the study of how matter and light interact History of biophysics — history of the study of physical processes relating to biology History of medical physics — history of the application of physics concepts, theories and methods to medicine.
History of neurophysics — history of the branch of biophysics dealing with the nervous system. History of chemical physics — history of the branch of physics that studies chemical processes from the point of view of physics. History of computational physics — history of the study and implementation of numerical algorithms to solve problems in physics for which a quantitative theory already exists.
History of condensed matter physics — history of the study of the physical properties of condensed phases of matter. History of Dynamics — history of the study of the causes of motion and changes in motion History of econophysics — history of the interdisciplinary research field, applying theories and methods originally developed by physicists in order to solve problems in economics History of electromagnetism — history of the branch of science concerned with the forces that occur between electrically charged particles.
History of geophysics — history of the physics of the Earth and its environment in space; also the study of the Earth using quantitative physical methods History of materials physics — history of the use of physics to describe materials in many different ways such as force, heat, light and mechanics.
History of mathematical physics — history of the application of mathematics to problems in physics and the development of mathematical methods for such applications and for the formulation of physical theories.
History of mechanics — history of the branch of physics concerned with the behavior of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment.
History of biomechanics — history of the study of the structure and function of biological systems such as humans, animals, plants, organs, and cells by means of the methods of mechanics.
History of classical mechanics — history of the one of the two major sub-fields of mechanics, which is concerned with the set of physical laws describing the motion of bodies under the action of a system of forces.
History of continuum mechanics — history of the branch of mechanics that deals with the analysis of the kinematics and the mechanical behavior of materials modeled as a continuous mass rather than as discrete particles.Analysis is the process of breaking a complex topic or substance into smaller parts in order to gain a better understanding of it.
The technique has been applied in the study of mathematics and logic since before Aristotle (– B.C.), though analysis as a formal concept is a relatively recent development.. The word comes from the Ancient Greek ἀνάλυσις (analysis, "a breaking up.
