  2. Principle of minimum energy - Wikipedia

    en.wikipedia.org/wiki/Principle_of_minimum_energy

    The principle of minimum energy is essentially a restatement of the second law of thermodynamics. It states that for a closed system, with constant external parameters and entropy, the internal energy will decrease and approach a minimum value at equilibrium. External parameters generally means the volume, but may include other parameters which ...

  3. Minimum total potential energy principle - Wikipedia

    en.wikipedia.org/wiki/Minimum_total_potential...

    The minimum total potential energy principle is a fundamental concept used in physics and engineering.It dictates that at low temperatures a structure or body shall deform or displace to a position that (locally) minimizes the total potential energy, with the lost potential energy being converted into kinetic energy (specifically heat).

  4. Thermodynamic equations - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_equations

    By the principle of minimum energy, there are a number of other state functions which may be defined which have the dimensions of energy and which are minimized according to the second law under certain conditions other than constant entropy. These are called thermodynamic potentials. For each such potential, the relevant fundamental equation ...

  5. Thermodynamic potential - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_potential

    In particular: (see principle of minimum energy for a derivation) [8] When the entropy S and "external parameters" (e.g. volume) of a closed system are held constant, the internal energy U decreases and reaches a minimum value at equilibrium. This follows from the first and second laws of thermodynamics and is called the principle of minimum ...

  6. Action principles - Wikipedia

    en.wikipedia.org/wiki/Action_principles

    The energy function in the action principles is not the total energy (conserved in an isolated system), but the Lagrangian, the difference between kinetic and potential energy. The kinetic energy combines the energy of motion for all the objects in the system; the potential energy depends upon the instantaneous position of the objects and ...

    Here's how to pinpoint when you're actually in this phase of life even if your symptoms (hot flashes, mood swings, stress, dryness) are nonspecific.

  8. Landauer's principle - Wikipedia

    en.wikipedia.org/wiki/Landauer's_principle

    Landauer's principle is a physical principle pertaining to the lower theoretical limit of energy consumption of computation. It holds that an irreversible change in information stored in a computer, such as merging two computational paths, dissipates a minimum amount of heat to its surroundings.
