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
The Newton and the Schrödinger equations in the absence of the macroscopic magnetic fields and in the inertial frame of reference are T-invariant: if X(t) is a solution then X(-t) is also a solution (here X is the vector of all dynamic variables, including all the coordinates of particles for the Newton equations and the wave function in the configuration space for the Schrödinger equation).
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.
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 .

Super Simple Songs was started in September 8, 2006 by teachers of a small English school in Japan. They created their own songs in place of children's songs that were too complex and difficult to be used in teaching. After increasing in popularity from other teachers, they released their first CD.
Mathematical fiction is a genre of creative fictional work in which mathematics and mathematicians play important roles. The form and the medium of the works are not important. The form and the medium of the works are not important.
