[edit] Zipf's law
George Kingsley Zipf is the eponym of Zipf's law, which states that while only a few words are used very often, many or most are used rarely,
where Pn is the frequency of a word ranked nth and the exponent a is almost 1. This means that the second item occurs approximately 1/2 as often as the first, and the third item 1/3 as often as the first, and so on. [1].
