統計力学
Stochastic forensics is inspired by the statistical mechanics method used in physics. Classical Newtonian mechanics calculates the exact position and momentum of every particle in a system. This works well for systems, such as the solar system, which consist of a small number of objects. However, it cannot be used to study things like a gas, which have intractably large numbers of molecules. Statistical mechanics, however, doesn't attempt to track properties of individual particles, but only the properties which emerge statistically. Hence, it can analyze complex systems without needing to know the exact position of their individual particles.
