Word Origin and History for non-revolution

revolution

late 14c., originally of celestial bodies, from Old French revolucion "course, revolution (of celestial bodies)" (13c.), or directly from Late Latin revolutionem (nominative revolutio) "a revolving," noun of action from past participle stem of Latin revolvere "turn, roll back" (see revolve).

General sense of "instance of great change in affairs" is recorded from mid-15c. Political meaning "overthrow of an established political system" first recorded c.1600, derived from French, and was especially applied to the expulsion of the Stuart dynasty under James II in 1688 and transfer of sovereignty to William and Mary.

Science definitions for non-revolution

revolution

[ rĕv′ə-lōō′shən ]

The motion of an object around a point, especially around another object or a center of mass.

A single complete cycle of such motion.

Usage

In everyday speech revolution and rotation are often used as synonyms, but in science they are not synonyms and have distinct meanings. The difference between the two terms lies in the location of the central axis that the object turns about. If the axis is outside the body itself-that is, if the object is orbiting about another object-then one complete orbit is called a revolution. But if the object is turning about an axis that passes through itself, then one complete cycle is called a rotation. This difference is often summed up in the statement Earth rotates on its axis and revolves around the Sun.
