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:
“I falter where I firmly trod,
And falling with my weight of cares
Upon the great world’s altar-stairs
That slope thro’ darkness up to God,”
—Alfred Tennyson (1809–1892)
