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:
“Of all the characters I have known, perhaps Walden wears best, and best preserves its purity. Many men have been likened to it, but few deserve that honor. Though the woodchoppers have laid bare first this shore and then that, and the Irish have built their sties by it, and the railroad has infringed on its border, and the ice-men have skimmed it once, it is itself unchanged, the same water which my youthful eyes fell on; all the change is in me.”
—Henry David Thoreau (1817–1862)
“Love is life. All, everything that I understand, I understand only because I love. Everything is, everything exists, only because I love. Everything is united by it alone. Love is God, and to die means that I, a particle of love, shall return to the general and eternal source.”
—Leo Tolstoy (1828–1910)
