Reversibility can refer to

• Reversible dynamics - a mathematical dynamical system, or physical laws of motion, for which time-reversed dynamics are well defined.
• Time reversibility
• Logical reversibility of a computation - a computational step for which a well-defined inverse exists.
• A reversible process in thermodynamics, a process or cycle such that the net change at each stage in the combined entropy of the system and its surroundings is zero.
• A reversible reaction 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.
• Reversibility in sterilization. See Doctors test easily reversible vasectomy.
• A reversible process in engineering, a process or operation of a system or device such that a net reverse in operation will accomplished the converse of the original function.
