Outline of physics
The following outline is provided as an overview of and topical guide to physics:
Physics – natural science that involves the study of matter and its motion through spacetime, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.
 Nature of physics
Physics can be described as all of the following:
- An academic discipline – one with academic departments, curricula and degrees; national and international societies; and specialized journals.
- A scientific field (a branch of science) – widely-recognized category of specialized expertise within science, and typically embodies its own terminology and nomenclature. Such a field will usually be represented by one or more scientific journals, where peer-reviewed research is published. There are several geophysics-related scientific journals.
- A natural science – one that seeks to elucidate the rules that govern the natural world using empirical and scientific method.
Physics started with a philosophical commitment to simplicity. It should not be considered a difficult subject (although it is deep); one can learn classical physics on a playground, which describes the motion of balls, swings, slides and merry-go-rounds.

 Famous physicists
- Ibn al-Haytham – Father of optics and discovered reflection and refraction.
- Archimedes – discovered the laws of flotation and developed Archimedes' principle.
- Galileo Galilei – "Father of modern physics.".
- Isaac Newton – Laid the groundwork for classical mechanics, made significant contributions to the field of optics and co-invented calculus. Often considered the greatest physicist of all time.
- Albert Einstein – Generally considered greatest scientist of the 20th century. Developed both the Special and General Theories of Relativity and proved the existence of atoms beyond doubt.
- Niels Bohr – made fundamental contributions to understanding atomic structure and quantum mechanics. Widely considered one of the greatest physicists of the 20th century.
- Richard Feynman – Expanded the theory of quantum electrodynamics, and developed the tool known as Feynman diagrams.
- Robert Oppenheimer – "Father of the atomic bomb."
- Nikola Tesla – One of the main influences of the second industrial revolution and widely known for his work on electromagnetism.
- Stephen Hawking – made fundamental contributions to black hole physics and cosmology. Also authored popular books on these subjects.

- 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. ..."

- J.C. Maxwell (1878). Matter and Motion. D. Van Nostrand. p. 9. ISBN 0-486-66895-9. "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. ISBN 0-470-61841-8. "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.
