The following outline is provided as an overview of and topical guide to physical science:
Physical science – branch of natural science that studies non-living systems, in contrast to the biological 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).
Physical science can be described as all of the following:
History of physical science – history of the branch of natural science that studies non-living systems, in contrast to the biological 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).
Physics – branch of science that studies matter[4] and its motion through space and time, along with related concepts such as energy and force.[5] Physics is one of the "fundamental sciences" because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics. According to physics, the physical laws of matter, energy and the fundamental forces of nature govern the interactions between particles and physical entities (such as planets, molecules, atoms or the subatomic particles). Some of the basic pursuits of physics, which include some of the most prominent developments in modern science in the last millennium, include:
Astronomy – science of celestial bodies and their interactions in space. Its studies includes the following:
(Note: Astronomy should not be confused with astrology, which assumes that people's destiny and human affairs in general correlate to the apparent positions of astronomical objects in the sky - although the two fields share a common origin, they are quite different; astronomers embrace the scientific method, while astrologers do not.)
Chemistry – branch of science that studies the composition, structure, properties and change of matter.[6][7] Chemistry is chiefly concerned with atoms and molecules and their interactions and transformations, for example, the properties of the chemical bonds formed between atoms to create chemical compounds. As such, chemistry studies the involvement of electrons and various forms of energy in photochemical reactions, oxidation-reduction reactions, changes in phases of matter, and separation of mixtures. Preparation and properties of complex substances, such as alloys, polymers, biological molecules, and pharmaceutical agents are considered in specialized fields of chemistry.
Earth science – the science of the planet Earth, as of 2014 the only identified life-bearing planet. Its studies include the following:
Medicine, Statistics, Logic, Mathematics, Physics
Kinetic energy, Space, Force, Mass, Matter
Magnetism, Maxwell's equations, Chemistry, Quantum mechanics, James Clerk Maxwell
Quantum mechanics, Hydrogen, Periodic table, Physics, Biology
Psychology, Molecular biology, Universe, Biophysics, Pharmacology
