Alternative form of Boltzmann's constant

(physics) The physical constant relating energy at the particle level with temperature observed at the bulk level. It is the gas constant R divided by the Avogadro's number N_A:- k=R/(N_rm A),

(physics) A hypothetical self-aware entity that arises due to random fluctuations of spacetime.

(physics, statistical mechanics) A particular probability distribution originally defined and used for describing particle speeds in idealized gases. Mathematically, it is the chi distribution with three degrees of freedom (the components of the velocity vector in Euclidean space), with a scale parameter measuring speeds in units proportional to the square root of the ratio of temperature and particle mass.

plural of Maxwell-Boltzmann distribution

plural of lattice Boltzmann method

(physics) A law stating that the total energy radiated per unit surface area of a black body across all wavelengths per unit time is directly proportional to the fourth power of the black body's thermodynamic temperature.

Any of a class of computational fluid dynamics (CFD) methods for fluid simulation. Instead of solving the Navier-Stokes equations directly, a fluid density on a lattice is simulated with streaming and collision (relaxation) processes.
