annihilationIn nuclear physics, a process in which a particle and its ‘mirror image’ particle called an antiparticle collide and disappear, with the creation of a burst of energy. The energy created is equivalent to the mass of the colliding particles in accordance with the mass-energy equation. For example, an electron and a positron annihilate to produce a burst of high-energy X-rays. See antimatter. |

| If the perceptible is annihilated, perception also will cease to exist; but the annihilation of perception does not cancel the existence of the perceptible. For many years of her life she had had two sons; but the crime and annihilation of Edward a few weeks ago, had robbed her of one; the similar annihilation of Robert had left her for a fortnight without any; and now, by the resuscitation of Edward, she had one again. There were days when she was unhappy, she did not know why,--when it did not seem worth while to be glad or sorry, to be alive or dead; when life appeared to her like a grotesque pandemonium and humanity like worms struggling blindly toward inevitable annihilation. |
