Free Energy

Free energy may refer to:

In science:

  • Thermodynamic free energy, the energy in a physical system that can be converted to do work, in particular:
    • Helmholtz free energy, the energy that can be converted into work at a constant temperature and volume
    • Work content, a related concept used in chemistry
    • Gibbs free energy, the energy that can be converted into work at a uniform temperature and pressure throughout a system
  • Variational free energy, a construct from Information theory that is used in Variational Bayesian methods

In pseudoscience:

  • Free energy device, a hypothetical device that creates energy in a hypothetical isolated system, i.e. without any external input, thereby contradicting the laws of thermodynamics
  • Free energy suppression, a conspiracy theory that advanced energy technologies are being suppressed by special interest groups

In music

  • Free Energy (band), a 5-piece rock band on DFA Records

Famous quotes containing the words energy and/or free:

    While the State becomes inflated and hypertrophied in order to obtain a firm enough grip upon individuals, but without succeeding, the latter, without mutual relationships, tumble over one another like so many liquid molecules, encountering no central energy to retain, fix and organize them.
    Emile Durkheim (1858–1917)

    That’s free enterprise, friends: freedom to gamble, freedom to lose. And the great thing—the truly democratic thing about it—is that you don’t even have to be a player to lose.
    Barbara Ehrenreich (b. 1941)
