What's the difference between demonstration and reaction?

Demonstration


Definition:

  • (n.) The act of demonstrating; an exhibition; proof; especially, proof beyond the possibility of doubt; indubitable evidence, to the senses or reason.
  • (n.) An expression, as of the feelings, by outward signs; a manifestation; a show.
  • (n.) The exhibition and explanation of a dissection or other anatomical preparation.
  • (n.) (Mil.) a decisive exhibition of force, or a movement indicating an attack.
  • (n.) The act of proving by the syllogistic process, or the proof itself.
  • (n.) A course of reasoning showing that a certain result is a necessary consequence of assumed premises; -- these premises being definitions, axioms, and previously established propositions.

Reaction


Definition:

  • (n.) Any action in resisting other action or force; counter tendency; movement in a contrary direction; reverse action.
  • (n.) The mutual or reciprocal action of chemical agents upon each other, or the action upon such chemical agents of some form of energy, as heat, light, or electricity, resulting in a chemical change in one or more of these agents, with the production of new compounds or the manifestation of distinctive characters. See Blowpipe reaction, Flame reaction, under Blowpipe, and Flame.
  • (n.) An action induced by vital resistance to some other action; depression or exhaustion of vital force consequent on overexertion or overstimulation; heightened activity and overaction succeeding depression or shock.
  • (n.) The force which a body subjected to the action of a force from another body exerts upon the latter body in the opposite direction.
  • (n.) Backward tendency or movement after revolution, reform, or great progress in any direction.
