The Kepler Problem In Stochastic ElectrodynamicsT). If the deterministic force field is simple harmonic, the properties of the system resemble closely those of the quantum-mechanical oscillator, but the extension to non-linear systems has proved to be a complex problem. The Kepler problem is an important test for stochastic electrodynamics, and t

Reversibility Versus Irreversibility in the Physical Universelaws, we change t into — t, then we get the same system or an equivalent one. This purely formal criterion needs some clarification. Let us suppose that the considered law is expressed as a differential system. In general, this system is not of first order (more frequently of second order). By intro

Adiabatical Invariance in Microphysicsn Lorentz himself — asked to the attendants what would become the oscillations of a classical pendulum if one undertakes to shorten its length very slowly. The answer to that question was immediately given by Einstein: under such conditions the quotient between the total energy . and the frequency .

Evolution of Non-Equilibrium Stable Thermodynamic Processes at the microscopic scale. Any evolution of the mean behaviour of such collective processes is characterized by two very important effects: the existence of fluctuations and the appearance of irreversibility. Indeed, the latter never occurs in the dynamic laws governing the trajectories of only a ve

Intrinsic Stochasticity and Irreversibility of Classical Quantum Systemscesses. This problem has been the object of many attempts. It is generally accepted that probabilistic processes can arise from deterministic dynamics through a process of “coarse-graining”, “contraction of the description” or by introducing extra dynamic approximations like the “molecular chaos”.

Common Structure of Non-Hamiltonian Dynamical Theories of Macroscopic Physicsable in Refs. 1,2. A well established level of perception consists of a class of macroscopic systems S (the elements of S are the systems that are investigated), another class of physical systems I (the elements of I are the measurement instruments) and a dynamical theory DT. A dynamical theory DT c
