**Rotation (mathematics)**— Rotation of an object in two dimensions around a point O. In geometry and linear algebra, a rotation is a transformation in a plane or in space that describes the motion of a rigid body around a fixed point. A rotation is different from a… …2

**rotation flap**— n a pedicle flap that is rotated on its base to graft an adjacent area * * * a local pedicle flap whose width is increased by having the edge distal to the defect form a curved line; the flap is then rotated and a counterincision is made at the… …3

**Line moiré**— is one type of moiré pattern; a pattern that appears when superposing two transparent layers containing correlated opaque patterns. Line moiré is the case when the superposed patterns comprise straight or curved lines. When moving the layer… …4

**Rotation around a fixed axis**— Rotational motion can occur around more than one axis at once, and can involve phenomena such as wobbling and precession. Rotation around a fixed axis is a special case of rotational motion, which does not involve those phenomena. The kinematics… …5

**Rotation matrix**— In linear algebra, a rotation matrix is a matrix that is used to perform a rotation in Euclidean space. For example the matrix rotates points in the xy Cartesian plane counterclockwise through an angle θ about the origin of the Cartesian… …6

**Rotation representation (mathematics)**— In geometry a rotation representation expresses the orientation of an object (or coordinate frame) relative to a coordinate reference frame. This concept extends to classical mechanics where rotational (or angular) kinematics is the science of… …7

**Rotation**— This article is about movement of a physical body. For other uses, see Rotation (disambiguation). A polyhedron resembling a sphere rotating around an axis. A rotation is a circular movement of an object around a center (or point) of rotation. A… …8

**Rotation (disambiguation)**— The term rotation can be used in several ways and includes various topics. Generally, it is used to denote (in 3D) 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… …9

**Rotation number**— This article is about the rotation number, which is sometimes called the map winding number or simply winding number. There is another meaning for winding number, which appears in complex analysis. In mathematics, the rotation number is an… …10

**rotation**— 1. Turning or movement of a body around its axis. 2. A recurrence in regular order of certain events, such as the symptoms of a periodic disease. 3. In medical education, a period of time on a particular service or specialty …13

**rotation axis**— noun : a simple axis of symmetry in a crystal about which the whole crystal configuration is brought into coincidence with its original aspect by a rotation of one half, one third, one fourth, or one sixth of a turn about the axis * * * Crystall …14

**rotation axis**— Crystall. an imaginary line through a crystal about which the crystal may be rotated a specified number of degrees and be brought back to its original position. Also called axis of symmetry, symmetry axis of rotation. Cf. symmetry element. [1900… …15

**line broadening**— ▪ spectroscopy in spectroscopy, the spreading across a greater wavelength, or frequency range, of absorption lines (dark) or emission lines (bright) in the radiation received from some object. The broadening is partly an extremely small… …16

**line of fixation**— a straight line extending through the center of rotation of the eye to the object of vision …17

**Differential rotation in stars**— What is differential rotation? *Differential rotation is when a rotating body has different angular velocities at different latitudes and/or depths of the body and/or in time. Differential rotation can be applied to any type of fluid body such as …19

**Differential rotation**— is seen when different parts of a rotating object move with different angular velocities (rates of rotation) at different latitudes and/or depths of the body and/or in time. This indicates that the object is not solid. In fluid objects, such as… …20

**Stellar rotation**— is the angular motion of a star about its axis. The rate of rotation can be measured from the spectrum of the star, or by timing the movements of active features on the surface.The rotation of a star produces an equatorial bulge due to… …
