Reversibility

Reversibility can refer to:
- Reversible dynamicsReversible dynamics- Mathematics :In mathematics, a dynamical system is invertible if the forward evolution is one-to-one, not many-to-one; so that for every state there exists a well-defined reverse-time evolution operator....
, a mathematical dynamical system, or physical laws of motion, for which time-reversed dynamics are well defined - Reversible diffusionReversible diffusionIn mathematics, a reversible diffusion is a specific example of a reversible stochastic process. Reversible diffusions have an elegant characterization due to the Russian mathematician Andrey Nikolaevich Kolmogorov....
, an example of a reversible stochastic processStochastic processIn probability theory, a stochastic process , or sometimes random process, is the counterpart to a deterministic process... - Time reversibilityTime reversibilityTime reversibility is an attribute of some stochastic processes and some deterministic processes.If a stochastic process is time reversible, then it is not possible to determine, given the states at a number of points in time after running the stochastic process, which state came first and which...
, a property of some stochastic processStochastic processIn probability theory, a stochastic process , or sometimes random process, is the counterpart to a deterministic process...
es - Reversible computingReversible computingReversible computing is a model of computing where the computational process to some extent is reversible, i.e., time-invertible. A necessary condition for reversibility of a computational model is that the transition function mapping states to their successors at a given later time should be...
, logical reversibility of a computation - a computational step for which a well-defined inverse exists - Reversible process (thermodynamics)Reversible process (thermodynamics)In thermodynamics, a reversible process, or reversible cycle if the process is cyclic, is a process that can be "reversed" by means of infinitesimal changes in some property of the system without loss or dissipation of energy. Due to these infinitesimal changes, the system is in thermodynamic...
, a process or cycle such that the net change at each stage in the combined entropy of the system and its surroundings is zero - Reversible reactionReversible reactionA reversible reaction is a chemical reaction that results in an equilibrium mixture of reactants and products. For a reaction involving two reactants and two products this can be expressed symbolically as...
in chemistry, for which the position of the chemical equilibrium is very sensitive to the imposed physical conditions; so the reaction can be made to run either forwards or in reverse by changing those conditions - A reversible process in engineeringTesla principleHistorically, the term Tesla principle was used to describe certain reversible processes invented by Nikola Tesla. However, this phrase is no longer in conventional use...
, a process or operation of a system or device such that a net reverse in operation will accomplished the converse of the original function - Reversible errorReversible errorIn law, a reversible error is an error by the trier of law or the trier of fact or malfeasance by one of the trying attorneys which results in an unfair trial...
, a legal mistake invalidating a trial - Part of the concrete operational stage in Jean Piaget's theory of cognitive developmentTheory of cognitive developmentPiaget's theory of cognitive development is a comprehensive theory about the nature and development of human intelligence first developed by Jean Piaget. It is primarily known as a developmental stage theory, but in fact, it deals with the nature of knowledge itself and how humans come gradually to...
, the mental process of understanding that numbers and objects can change and then return to their original state - In muscle training, reversibility is when the adaptations that have occurred during training are reversed when training stops
