Granularity - Physics

Physics

A fine-grained description of a system is a detailed, low-level model of it. A coarse-grained description is a model where some of this fine detail has been smoothed over or averaged out. The replacement of a fine-grained description with a lower-resolution coarse-grained model is called coarse graining. (See for example the second law of thermodynamics)

Famous quotes containing the word physics:

    Although philosophers generally believe in laws and deny causes, explanatory practice in physics is just the reverse.
    Nancy Cartwright (b. 1945)

    The pace of science forces the pace of technique. Theoretical physics forces atomic energy on us; the successful production of the fission bomb forces upon us the manufacture of the hydrogen bomb. We do not choose our problems, we do not choose our products; we are pushed, we are forced—by what? By a system which has no purpose and goal transcending it, and which makes man its appendix.
    Erich Fromm (1900–1980)

    Now the twitching stops. Now you are still. We are through with physiology and theology, physics begins.
    Alfred Döblin (1878–1957)
