jagamisfunktsiooni
Jagamisfunktsiooni, known in English as the partition function, is a fundamental concept in statistical mechanics and thermodynamics. It is a mathematical object that encodes all the thermodynamic information about a system in thermal equilibrium. Specifically, for a system with discrete energy levels $E_i$ and corresponding degeneracies $g_i$, the canonical partition function $Z$ is defined as the sum over all accessible states, weighted by the Boltzmann factor: $Z = \sum_i g_i e^{-E_i/k_B T}$, where $k_B$ is the Boltzmann constant and $T$ is the absolute temperature.
The partition function serves as a bridge between the microscopic properties of a system (its energy levels)
The partition function is particularly useful in systems where the number of possible states is very large,
