In theoretical physics, a bare particle is an excitation of an elementary quantum field. Such a particle is not identical to the particles observed in the experiments: the real particles are dressed particles that also include additional particles surrounding the bare one.
Famous quotes containing the words bare and/or particle:
“In the woods in a winter afternoon one will see as readily the origin of the stained glass window, with which Gothic cathedrals are adorned, in the colors of the western sky seen through the bare and crossing branches of the forest.”
—Ralph Waldo Emerson (1803–1882)
“The way to learn German, is, to read the same dozen pages over and over a hundred times, till you know every word and particle in them, and can pronounce and repeat them by heart.”
—Ralph Waldo Emerson (1803–1882)
