Nonlinear generally refers to a situation that has a disproportionate cause and effect.

In science and mathematics, nonlinearity can refer to:

  • Nonlinear element, or nonlinear device, is an electrical element which does not have a linear relationship between current and voltage, e.g., a diode
  • Nonlinear optics, in physics, examines the properties of light in media in which the polarization responds nonlinearly to the electric field.
  • Nonlinear regression, in statistics, represents fitting a model equation that is not linear in its parameters to the data in a data table.
  • Nonlinear system, in mathematics, represents a system whose behavior is not expressible as a linear function of its descriptors.
  • Nonlinearity (journal) is a peer-reviewed scientific journal of the Institute of Physics and the London Mathematical Society.

In computing:

  • Nonlinear gameplay, in computer and video games, presents players with challenges that can be completed in a number of different sequences.
  • Non-linear editing system, an audio and video editing term for a system which can perform random access on the source material.
  • Non-Linear Systems, a defunct computer manufacturer

In the arts:

  • Nonlinear narratives, in the arts, is a term used to describe events portrayed in a non-chronological manner.
