In physics, a translation is the operation changing the positions of all objects according to the formula

where xyz) is a constant vector. Such an operation can be generalized to other coordinates, for example the time coordinate.


Because of Noether's theorem, the translational symmetry is equivalent to momentum conservation.

physics -> Modern Physics Most of classical physics is concerned with matter and energy on the normal scale of observation; by contrast, much of modern physics is concerned with the behavior of matter and energy under extreme conditions or on the very large or very small scale.

Solid-state physics is concerned with the properties exhibited by atoms and molecules because of their association and regular, periodic arrangement in crystals.
Translation (geometry) - Wikipedia, the free encyclopedia (277 words)
In Euclidean geometry, a translation, or translation operator, is an affine transformation of Euclidean space which moves every point by a fixed distance in the same direction.
The set of all translations form the translation group T, which is isomorphic to the space itself, and a normal subgroup of Euclidean group E(n).
Since a translation is an affine transformation but not a linear transformation, homogeneous coordinates are normally used to represent the translation operator by a matrix.
