In physics, thermalisation (or thermalization) is the process of physical bodies reaching thermal equilibrium through mutual interaction. In general, the natural tendency of a system is towards a state of equipartition of energy and uniform temperature that maximizes the system's entropy .
In the cosmological 'thermalization problem', three main eras are distinguished: the thermalization or temperature-era, the -era and the -era, each with slightly different physical conditions due to the change in the density and temperature of particles caused by the Hubble expansion.
The phenomenon, when taken to mean "hot water freezes faster than cold", is difficult to reproduce or confirm because it is ill-defined. [4] Monwhea Jeng proposed a more precise wording: "There exists a set of initial parameters, and a pair of temperatures, such that given two bodies of water identical in these parameters, and differing only in initial uniform temperatures, the hot one will ...
The original intent was to find a physics problem worthy of numerical simulation on the then-new MANIAC computer. Fermi felt that thermalization would pose such a challenge. As such, it represents one of the earliest uses of digital computers in mathematical research; simultaneously, the unexpected results launched the study of nonlinear systems.
The time needed to connect power-hungry data centres to the electricity grid could blunt France's advantage using its abundant nuclear power to lure billions of dollars of investment into ...

Examples of this would include the occupation of a given momentum in a gas of particles, [4] [5] or the occupation of a particular site in a lattice system of particles. [5] Notice that while the ETH is typically applied to "simple" few-body operators such as these, [ 4 ] these observables need not be local in space [ 5 ] - the momentum number ...
