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.

PhysComp '96 was held in Boston in November of 1996.
Reversible computing at MIT is a large and active area of research, with investigations reaching from the levels of the physics of computation and theory of reversible computing, through the circuit techniques for implementing reversible logic, to the development of instruction sets and programming languages which support fully reversible computation."

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.
A reversible process changes the state of a system in such a way that the net change in the combined entropy of the system and its surroundings is zero.
Reversible processes define the boundaries of how efficient heat engines can be in thermodynamics and engineering: a reversible process is one where no heat is lost from the system as "waste", and the machine is thus as efficient as it can possibly be (see Carnot cycle).
