annihilationIn physics, a reaction in which a particle and its antiparticle (see antimatter) collide and disappear. The annihilation releases energy equal to the original mass m multiplied by the square of the speed of light c, or E = mc2, in accordance with Albert Einstein's special theory of relativity. The energy can appear directly as gamma rays or can convert back to particles and antiparticles (see pair production). |

| 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. |
