31Bose–Einstein statistics — In statistical mechanics, Bose Einstein statistics (or more colloquially B E statistics) determines the statistical distribution of identical indistinguishable bosons over the energy states in thermal equilibrium.ConceptBosons, unlike fermions,… …
32Particle statistics — refers to the particular description of particles in statistical mechanics. The three main types of particle statistics are:* For classical systems: Maxwell Boltzmann statistics (M B statistics)::ar{n} = frac{1}{e^{left(epsilon mu ight)/k T* For …
33Bose-Einstein statistics — noun (physics) statistical law obeyed by a system of particles whose wave function is not changed when two particles are interchanged (the Pauli exclusion principle does not apply) • Topics: ↑physics, ↑natural philosophy • Hypernyms: ↑law, ↑law… …

39Directional statistics — is the subdiscipline of statistics that deals with directions (unit vectors in Rn), axes (lines through the origin in Rn) or rotations in Rn. More generally, directional statistics deals with observations on compact Riemannian manifolds. The… …
40Fer|mi-Di|rac statistics — «FUR mee duh RAK», a statistical theory in quantum mechanics which holds that in the distribution of nuclear particles of a given type, only one of a set of identical particles may occupy a particular quantum mechanical state. ╂[< Enrico Fermi …
