Relaxation stands quite generally for a release of tension, a return to equilibrium.

In the sciences, the term is used in the following ways:

  • Relaxation (physics), and more in particular:
    • Relaxation (NMR), processes by which nuclear magnetization returns to the equilibrium distribution
    • Dielectric relaxation, the delay in the dielectric constant of a material
    • Structural relaxation, responsible for the glass transition
    • Vibrational energy relaxation, the process by which molecules in high energy quantum states return to the Maxwell-Boltzmann distribution.
  • In mathematics:
    • Relaxation technique (mathematics), a technique for transforming hard constraints into easier ones
    • Relaxation method, for numerically solving elliptic partial differential equations
  • In computer science:
    • Relaxation, the act of substituting alternative program code during linking

In Physiology, Hypnosis, Meditation, Recreation:

  • Relaxation technique, an activity that helps a person to relax
  • Relaxed in Flow (psychology), a state of arousal, flow, over-learned self-control and relaxation
  • Relaxation (psychology), the emotional state of low tension

Famous quotes containing the word relaxation:

    Worst of all, there is no sign of any relaxation of antisemitism. Logically it has nothing to do with Fascism. But the human race is imitative rather than logical; and as Fascism spreads antisemitism spreads.
    George Bernard Shaw (1856–1950)
