The act of turning, as a wheel or a solid body on its axis, as distinguished from the progressive motion of a revolving round another body or a distant point; thus, the daily turning of the earth on its axis is a rotation; its annual motion round the sun is a revolution
The number of years required to establish and grow trees to a specified size, product, or condition of maturity A pine rotation may range from as short as 20 years for pulpwood to more than 60 years for sawtimber
In the context of spins and qubits, a rotation around by an angle is an operation of the form The operator may be any unit combination of Pauli matrices This defines an axis in three-space, and in the Bloch sphere representation, the operation has the effect suggested by the terminology
The number of years required to establish and grow trees to a specified size, product or condition of maturity A pine rotation may range from as short as 20 years for pulpwood to more than 60 years for sawtimber
The number of years required to establish and grow timber crops to a specified condition of maturity The rotation age for Douglas Fir in the Umpqua National Forest is 80 years
The spin imparted to the ball at the moment of delivery which results in pin "action"; specifically, motion of the pins which is horizontal, rather than vertical, since a horizontally spinning pin covers more of the lane
A rotation in the plane through an angle q and about a point P is a rigid motion T fixing P so that if Q is distinct from P, then the angle between the lines PQ and PT(Q) is always q
); "crop rotation makes a balanced demand on the fertility of the soil"; "the manager had only four starting pitchers in his rotation" a single complete turn (axial or orbital); "the plane made three rotations before it crashed"; "the revolution of the earth about the sun takes one year" (mathematics) a transformation in which the coordinate axes are rotated by a fixed angle about the origin
A transformation that moves all points around the center of rotation A rotation maintains each point's distance to the center of rotation and to each other
The rotation of a group of things or people is the fact of them taking turns to do a particular job or serve a particular purpose. If people do something in rotation, they take turns to do it. Once a month we met for the whole day, and in rotation each one led the group
A cropping system in which crops are grown in a field in a fixed annual sequence A rotation reduces the build up of diseases and pests, aids weed control, improves soil fertility, spreads the risk of crop failure and allows even distribution of labour requirements
The number of years required to establish and grow trees to a specified size, product or condition of maturity For example, oaks may have an 80-year rotation for sawlogs and Scotch pine a 10-year rotation for Christmas trees -S- Salvage cut -- Harvesting damaged or defective trees for their economic value
a single complete turn (axial or orbital); "the plane made three rotations before it crashed"; "the revolution of the earth about the sun takes one year"
Rotation refers to the position of the tip relative to the upper lip A "rotated tip" is pushed away from the upper lip, as can be done by gently pushing your tip up with your finger (Too much rotation causes excessive nostril show) A counter-rotated tip brings the tip closer to the lip, as occurs when the tip of the nose is pushed toward the upper lip An ideal tip is slightly rotated up See droopy tip
a planned recurrent sequence (of crops or personnel etc ); "crop rotation makes a balanced demand on the fertility of the soil"; "the manager had only four starting pitchers in his rotation"
Applied to cropping, the practice of growing different crops on the same land in a regular, recurring sequence Rotation is adopted to hinder the development or because of complement effects, or demands on the soil or for convenience of spreading the times of peak labour demand
