Translational Symmetry

In geometry, a translation "slides" an object by a a: Ta(p) = p + a.

Famous quotes containing the word symmetry:

    What makes a regiment of soldiers a more noble object of view than the same mass of mob? Their arms, their dresses, their banners, and the art and artificial symmetry of their position and movements.
    George Gordon Noel Byron (1788–1824)
