• Reversible diffusion, an example of a reversible stochastic process
• Time reversibility, a property of some stochastic processes

• Reversible computing, logical reversibility of a computation - a computational step for which a well-defined inverse exists
• Reversible process (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
• 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
• 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
