In statistical mechanics, the statistical weight is the relative probability (possibly unnormalized) of a particular feature of a state. If the energy associated with the feature is ΔE, the statistical weight is given by the Boltzmann factor e-ΔE/kT, where k is the Boltzmann constant and T is the temperature in kelvin.
The statistical weight is a convenient shorthand that is often used in transfer matrix solutions of problems in statistical mechanics.
Famous quotes containing the word weight:
“Europe has lived on its contradictions, flourished on its differences, and, constantly transcending itself thereby, has created a civilization on which the whole world depends even when rejecting it. This is why I do not believe in a Europe unified under the weight of an ideology or of a technocracy that overlooked these differences.”
—Albert Camus (1913–1960)
