The following outline is provided as an overview of and topical guide to physics:

Physicsnatural science that involves the study of matter[1] and its motion through spacetime, along with related concepts such as energy and force.[2] More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.[3][4][5]

What type of subject is physics?

[edit]

Physics can be described as all of the following:

Branches

[edit]

History

[edit]

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

General concepts

[edit]

Basic principles

[edit]

Physics – branch of science that studies matter[9] and its motion through space and time, along with related concepts such as energy and force.[10] 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:

Gravity, light, physical system, physical observation, physical quantity, physical state, physical unit, physical theory, physical experiment

Theoretical concepts: mass–energy equivalence, elementary particle, physical law, fundamental force, physical constant

Fundamental concepts

Notes

  1. ^ Richard Feynman begins his Lectures with the atomic hypothesis, as his most compact statement of all scientific knowledge: "If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generations ..., what statement would contain the most information in the fewest words? I believe it is ... that all things are made up of atoms – little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another. ..." R. P. Feynman; R. B. Leighton; M. Sands (1963). The Feynman Lectures on Physics. Vol. 1. p. I-2. ISBN 978-0-201-02116-5.
  • ^ J. C. Maxwell (1878). Matter and Motion. D. Van Nostrand. p. 9. ISBN 978-0-486-66895-6. Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events.
  • ^ H.D. Young; R.A. Freedman (2004). University Physics with Modern Physics (11th ed.). Addison Wesley. p. 2. Physics is an experimental science. Physicists observe the phenomena of nature and try to find patterns and principles that relate these phenomena. These patterns are called physical theories or, when they are very well established and of broad use, physical laws or principles.
  • ^ S. Holzner (2006). Physics for Dummies. Wiley. p. 7. Bibcode:2005pfd..book.....H. ISBN 978-0-470-61841-7. Physics is the study of your world and the world and universe around you.
  • ^ Note: The term 'universe' is defined as everything that physically exists: the entirety of space and time, all forms of matter, energy and momentum, and the physical laws and constants that govern them. However, the term 'universe' may also be used in slightly different contextual senses, denoting concepts such as the cosmos or the philosophical world.

  • ^ At the start of The Feynman Lectures on Physics, Richard Feynman offers the atomic hypothesis as the single most prolific scientific concept:『If, in some cataclysm, all [] scientific knowledge were to be destroyed [save] one sentence [...] what statement would contain the most information in the fewest words? I believe it is [...] that all things are made up of atoms – little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another ...』(Feynman, Leighton & Sands 1963, p. I-2)
