In physics, the **dissipation factor** (DF) is a measure of loss-rate of energy of a mode of oscillation (mechanical, electrical, or electromechanical) in a dissipative system. It is the reciprocal of quality factor, which represents the quality of oscillation.

### Famous quotes containing the words factor and/or dissipation:

“It is change, continuing change, inevitable change, that is the dominant *factor* in society today. No sensible decision can be made any longer without taking into account not only the world as it is, but the world as it will be.... This, in turn, means that our statesmen, our businessmen, our everyman must take on a science fictional way of thinking.”

—Isaac Asimov (1920–1992)

“The more specific idea of evolution now reached is—a change from an indefinite, incoherent homogeneity to a definite, coherent heterogeneity, accompanying the *dissipation* of motion and integration of matter.”

—Herbert Spencer (1820–1903)
