Statistical Weight

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 eE/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:

    The only thing of weight that can be said against modern honour is that it is directly opposite to religion. The one bids you bear injuries with patience, the other tells you if you don’t resent them, you are not fit to live.
    Bernard Mandeville (1670–1733)
