== Applications and examples == Exponential decay occurs in a wide variety of situations. Most of these fall into the domain of the natural sciences. Many decay processes that are often treated as exponential, are really only exponential so long as the sample is large and the law of large numbers holds. For small samples, a more general analysis i...
