Statistical weight of macrostate¶
If a physical system can be described as having several states which can be occupied by different numbers of particles but with the total number of particles being conserved and a condition that all allowed microstates of the closed system are equiprobable, the formula for the statistical weight of the system can be found in combinatorics.
Notes:
Law can also be represented in form \(W = \frac{N!}{\prod_i (N_i!)}\) (
W = factorial(N) / Product(factorial(N_i), i)
)
