1. Annihilationnoun

   The act of reducing to nothing. The state of being reduced to nothing.

   Etymology: from annihilate.

   God hath his influence into the very essence of things, without which their utter annihilation could not choose but follow. Richard Hooker, b. v. § 56.

   That knowledge, which as spirits we obtain,
   Is to be valu’d in the midst of pain:
   Annihilation were to lose heav’n more:
   We are not quite exil’d, where thought can soar. Dryden.

1. Annihilation

   In particle physics, annihilation is the process that occurs when a subatomic particle collides with its respective antiparticle to produce other particles, such as an electron colliding with a positron to produce two photons. The total energy and momentum of the initial pair are conserved in the process and distributed among a set of other particles in the final state. Antiparticles have exactly opposite additive quantum numbers from particles, so the sums of all quantum numbers of such an original pair are zero. Hence, any set of particles may be produced whose total quantum numbers are also zero as long as conservation of energy and conservation of momentum are obeyed.During a low-energy annihilation, photon production is favored, since these particles have no mass. High-energy particle colliders produce annihilations where a wide variety of exotic heavy particles are created. The word "annihilation" takes use informally for the interaction of two particles that are not mutual antiparticles – not charge conjugate. Some quantum numbers may then not sum to zero in the initial state, but conserve with the same totals in the final state. An example is the "annihilation" of a high-energy electron antineutrino with an electron to produce a W boson-. If the annihilating particles are composite, such as mesons or baryons, then several different particles are typically produced in the final state.

1. Annihilation

   Annihilation is defined as "total destruction" or "complete obliteration" of an object; having its root in the Latin nihil. A literal translation is "to make into nothing". In physics, the word is used to denote the process that occurs when a subatomic particle collides with its respective antiparticle. Since energy and momentum must be conserved, the particles are simply transformed into new particles. They do not disappear from existence. Antiparticles have exactly opposite additive quantum numbers from particles, so the sums of all quantum numbers of the original pair are zero. Hence, any set of particles may be produced whose total quantum numbers are also zero as long as conservation of energy and conservation of momentum are obeyed. When a particle and its antiparticle collide, their energy is converted into a force carrier particle, such as a gluon, W/Z force carrier particle, or a photon. These particles are afterwards transformed into other particles. During a low-energy annihilation, photon production is favored, since these particles have no mass. However, high-energy particle colliders produce annihilations where a wide variety of exotic heavy particles are created.

Examples of Annihilation in a Sentence

5. Jonathan Greenblatt:

   Well, Whoopi, there’s no question that the Holocaust was about race. That’s how the Nazis saw it as they perpetrated the systematic annihilation of the Jewish people across continents, across countries with deliberate and ruthless cruelty, you see, Hitler’s ideology, the Third Reich, was predicated on the idea that the Aryans, the Germans, were a ‘master race,’ and the Jews were a subhuman race. It was racialized anti-Semitism.
