A mathematical or physical process is time-reversible if the dynamics of the process remain well-defined when the sequence of time-states is reversed.. A deterministic process is time-reversible if the time-reversed process satisfies the same dynamic equations as the original process; in other words, the equations are invariant or symmetrical under a change in the sign of time.
T-symmetry or time reversal symmetry is the theoretical symmetry of physical laws under the transformation of time reversal, :. Since the second law of thermodynamics states that entropy increases as time flows toward the future, in general, the macroscopic universe does not show symmetry under time reversal. In other words, time is said to be ...
Reversibility can refer to: Time reversibility , a property of some mathematical or physical processes and systems for which time-reversed dynamics are well defined Reversible diffusion , an example of a reversible stochastic process
There are two major, closely related types of reversibility that are of particular interest for this purpose: physical reversibility and logical reversibility. [ 2 ] A process is said to be physically reversible if it results in no increase in physical entropy ; it is isentropic .
The principle of microscopic reversibility in physics and chemistry is twofold: First, it states that the microscopic detailed dynamics of particles and fields is time-reversible because the microscopic equations of motion are symmetric with respect to inversion in time ( T-symmetry );
The Rat is "logical and pragmatic" for the most part, says Stardust, though notes they "do make rash decisions on occasion." Stardust explains, "The Rat seeks our intelligent company, which is why ...
The continuous time Markov chain is characterized by the transition rates, the derivatives with respect to time of the transition probabilities between states i and j. Let X t {\displaystyle X_{t}} be the random variable describing the state of the process at time t , and assume the process is in a state i at time t .
The other two teams in the top five are the two semifinal game losers. Texas finishes the season at No. 4 after losing 28-14 to the Buckeyes in the Cotton Bowl. No. 5 Penn State lost 27-24 to ...
