    Usage: {Constant}, {Continual}, {Perpetual}. These words are

           qualified sense. Constant denotes, in its absolute
           sense, unchangeably fixed; as, a constant mind or
           purpose. In its qualified sense, it marks something as
           a ``standing'' fact or occurence; as, liable to
           constant interruptions; constantly called for.
           Continual, in its absolute sense, coincides with
           continuous. See {Continuous}. In its qualified sense,
           it describes a thing as occuring in steady and rapid
           succession; as, a round of continual calls;
           continually changing. Perpetual denotes, in its
           absolute sense, what literally never ceases or comes
           to an end; as, perpetual motion. In its qualified
           sense, it is used hyperbolically, and denotes that
           which rarely ceases; as, perpetual disturbance;
           perpetual noise; perpetual intermeddling.

       differential equation having the same value during all
       changes in the values of the variables.
    
    
  3. \Con"stant\, n.
    1. (Astron.) A number whose value, when ascertained (as by
       observation) and substituted in a general mathematical
       formula expressing an astronomical law, completely
       determines that law and enables predictions to be made of
       its effect in particular cases.
    
    2. (Physics) A number expressing some property or condition
       of a substance or of an instrument of precision; as, the
       dielectric constant of quartz; the collimation constant of
       a transit instrument.
    
    {Aberration constant}, or {Constant of aberration} (Astron.),
       a number which by substitution in the general formula for
       aberration enables a prediction to be made of the effect
       of aberration on a star anywhere situated. Its value is

    {Constant of integration} (Math.), an undetermined constant
