From Wikipedia, the free encyclopedia

Physics (Greek: physis–φύσις meaning "nature") is the natural science which examines basic concepts such as mass, charge, matter [1] and its motion and all that derives from these, such as energy, force and spacetime. [2] More broadly, it is the general analysis of nature, conducted in order to understand how the world and universe behave. [3]

Sands (1963), The Feynman Lectures on Physics, ISBN  0-201-02116-1 Hard-cover. p.1-1 Feynman begins 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. ..." vol.

These patterns are called physical theories or, when they are very well established and of broad use, physical laws or principles."
