Rotation (disambiguation)

The term rotation can be used in several way and includes various topics. Generally, it's used to denote the rotation of movement of a rigid body in such a way that any given point of that body remains at a constant distance from some other fixed point More specifically, it is applicable to:

• The farming pratice of crop rotation.\n* The business management approach of job rotation.\n* The International Earth Rotation and Reference Systems Service monitors the Earth's rotation.

In science:

• The differential rotation of objects.\n* The Galaxy rotation problem concening discrepancy between the observed rotation.\n* The optical rotation polarization.\n* The reverse rotation effect being an optical illusion.\n* The rotation curve for the variation in a circular orbital.\n* The synchronous rotation of orbiting bodies.

In geometry and mathematics:

• The axis, such that a geometric figure can be rotated.\n* The rotation group which contains all 3D rotations\n* A coordinate rotation is the transformation of coordinate systems.\n* An improper rotation producing an inversion.\n* The symmetry of an operation which rotates an object using a point on that object as its center.

In music:\n* An order operation that may be performed on a set of pitcheses or pitch classes, where the last member is placed first. Sets which may be mapped onto each other through rotation are rotationally equivalent. See: transformation, permutation Rotation is also the name of a billiards game. In baseball pitching, the rotation is the group of starting pitchers for a team, and the order in which they pitch.
