If you can rotate (or turn) a figure around a center point by fewer than 360° and the figure appears unchanged, then the figure has rotation symmetry. The point around which you rotate is called the center of rotation, and the smallest angle you need to turn is called the angle of rotation.

What is the smallest rotation that returns an object to its original state? geometry/rotation.s ; 720 degrees. Objects are made of bosons (integer-spin particles) and fermions; (half-odd-integer spin particles), and the wave function of a fermion changes sign upon being rotated by 360 degrees.

public class Rotation extends Object; implements Serializable ... Focus is oriented on what a rotation do rather than on its underlying representation. Once it has been built, and regardless of its internal representation, a rotation is an operator which basically transforms three dimensional vectors into other...

In a series of four experiments we show how the cross-channel geometry affects the propagation and trapping of internal tides and we discuss the zonal penetration scale of wave energy, away from the continental slope. ... In case of rotation, near the continental slope the Poincare waves that arise in the absence of a...
