What is physics?


Physics (from Ancient Greek: φύσις physis "nature") is a natural science that involves the study of matter and its motion through space and time, 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.

Famous quotes containing the word physics:

    ... it is as true in morals as in physics that all force is imperishable; therefore the consequences of a human action never cease.
    Tennessee Claflin (1846–1923)

    The fundamental laws of physics do not describe true facts about reality. Rendered as descriptions of facts, they are false; amended to be true, they lose their explanatory force.
    Nancy Cartwright (b. 1945)

    We must be physicists in order ... to be creative since so far codes of values and ideals have been constructed in ignorance of physics or even in contradiction to physics.
    Friedrich Nietzsche (1844–1900)
