annihilation

Examples of annihilation in the following topics:

• Matter and Antimatter

  • Furthermore, mixing matter and antimatter can lead to the annihilation of both, in the same way that mixing antiparticles and particles does.
  • If antimatter-dominated regions of space existed, the gamma rays produced in annihilation reactions along the boundary between matter and antimatter regions would be detectable.

• Photon Interactions and Pair Production

  • The electron and positron can annihilate and produce two 0.511 MeV gamma photons.
  • If all three gamma rays, the original with its energy reduced by 1.022 MeV and the two annihilation gamma rays, are detected simultaneously, then a full energy peak is observed.

• Criteria to Evaluate Ends and Means

  • An immoral objective can be achieved "efficiently. " Nazi Germany sought "efficient" means to achieve the annihilation of an ethnic group.

• Emission Topography

  • The encounter annihilates both electron and positron, producing a pair of annihilation (gamma) photons moving in approximately opposite directions.

• Energy, Mass, and Momentum of Photon

  • A photon can also be emitted when a particle and its corresponding antiparticle are annihilated.

• Range Wars

  • Of all the feuds that have taken place throughout American history, the Pleasant Valley War was the most costly, resulting in an almost complete annihilation of the two families involved.

• Disease in the New World

  • Many island-based groups were annihilated: the Caribs and Arawaks of the Caribbean nearly ceased to exist, as did the Beothuks of Newfoundland.

• Sorting Out Variations on the Terms "Constructionism" and Constructivism"

  • Few individuals would deny, for example, that if mankind were to someday succeed in self-annihilation, the planet and the rest of the universe would continue to exist apart from our meaning-making activity.

• Containment to Rollback

  • In American strategic language, rollback is the policy of totally annihilating an enemy army and occupying the country.

• The Conflict Perspective

  • He theorized that the policies of the power elite would result in the "increased escalation of conflict, production of weapons of mass destruction, and possibly the annihilation of the human race. "
