Kolmogorov's law of fragmentation states that the size of an individual particle in a large collection of particles resulting from the fragmentation of a mineral compound will have an approximate lognormal distribution, where a random variable X is said to have a lognormal distribution if log(X) has a normal distribution. The law, which was first noted empirically and then later given a theoretical basis by Kolmogorov, has been applied to a variety of engineering studies. For instance, it has been used in the analysis of the size of randomly chosen gold particles from a collection of gold sand. A less obvious

A less obvious application of the law has been to a study of the stress release in earthquake fault zones (see Lomnitz, C., “Global Tectonics and Earthquake Risk," Developments in Geotectonics, Elsevier, Amsterdam, 1979). Suppose that a sample of 10 grains of metallic sand taken from a large sand pile have respective lengths (in millimeters): 2.2, 3.4, 1.6, 0.8, 2.7, 3.3, 1.6, 2.8, 2.5, 1.9 Estimate the percentage of sand grains in the entire pile whose length is between 2 and 3 mm. fou
