  2. Reversibility - Wikipedia

    en.wikipedia.org/wiki/Reversibility

    Reversibility can refer to: Time reversibility , a property of some mathematical or physical processes and systems for which time-reversed dynamics are well defined Reversible diffusion , an example of a reversible stochastic process

  3. Reversible computing - Wikipedia

    en.wikipedia.org/wiki/Reversible_computing

    There are two major, closely related types of reversibility that are of particular interest for this purpose: physical reversibility and logical reversibility. [ 2 ] A process is said to be physically reversible if it results in no increase in physical entropy ; it is isentropic .

  4. Reversible process (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Reversible_process...

    The dependence of work on the path of the thermodynamic process is also unrelated to reversibility, since expansion work, which can be visualized on a pressure–volume diagram as the area beneath the equilibrium curve, is different for different reversible expansion processes (e.g. adiabatic, then isothermal; vs. isothermal, then adiabatic ...

  5. Time reversibility - Wikipedia

    en.wikipedia.org/wiki/Time_reversibility

    A mathematical or physical process is time-reversible if the dynamics of the process remain well-defined when the sequence of time-states is reversed.. A deterministic process is time-reversible if the time-reversed process satisfies the same dynamic equations as the original process; in other words, the equations are invariant or symmetrical under a change in the sign of time.

  6. Microscopic reversibility - Wikipedia

    en.wikipedia.org/wiki/Microscopic_reversibility

    The principle of microscopic reversibility in physics and chemistry is twofold: First, it states that the microscopic detailed dynamics of particles and fields is time-reversible because the microscopic equations of motion are symmetric with respect to inversion in time ( T-symmetry );

  7. Thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Thermodynamics

    Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation.

    The Kremlin said on Sunday that the significance of the phone call between Vladimir Putin and Donald Trump was that now Russia and the United States would speak about peace and not war. "This is a ...

  9. Irreversible process - Wikipedia

    en.wikipedia.org/wiki/Irreversible_process

    The reversibility of thermodynamics must be statistical in nature; that is, it must be merely highly unlikely, but not impossible, that a system will lower in entropy. In other words, time reversibility is fulfilled if the process happens the same way if time were to flow in reverse or the order of states in the process is reversed (the last ...
