# Viktor Jakovlevič Bunjakovskij

Viktor Jakovlevič Bunjakovskij was an important Russian mathematician (3.12.1804 - 30.11.1889), who played an important role in improving the level of mathematical education, as did other mathematicians of his time, such as M.S. Ostrogradskij or P.L. Čebyšev.

In 1824 Bunjakovskij received the bachelor’s degree, in 1825, he was appointed doctor of mathematics by the Paris Faculté des sciences. In 1883, Bunjakovskij, who mostly worked in the realm of number theory and probability theory, published his catalogue of scientific works (Liste des travaux mathématiques de Victor Bouniakowsky; SPb 1883), which points out 108 scholarly titles.

In 1847, Bunjakovskij published an article in the third volume (part II) of the journal Sovremennik, which was entitled: „On the possibility to apply determining measures of confi-dence to the results of some observing sciences, particularly statistics“. Irrespective of the importance this article has, in a historical perspective, with regard to establishing statistics as a methodological discipline in its own right, Bunjakovskij’s article represents – not only for Russia – one of the earliest quotations where the possibility and reasonability of applying sta-tistics to, among others, philological questions is being discussed.

Thus, at the very ending of this article, Bunjakovskij writes:

“[…] It would be time now, to finish the present article; it may be allowed, however, in accordance with the analogy of the matter at stake, to add a couple of words with regard to another application of probability analysis, to which obviously no-one has ever before drawn the attention. The new application includes grammatical and etymological studies of a language, as well as comparative philology. However strange such studies may, at first sight, seem for a mathematical analysis, yet I am fully convinced that a broad field for strictly mathematical ruminations opens up before us. My claim is not so much based on more or less uncertain conjectures and suppositions but on a critical evaluation of the object, on a number of attempts I have already made, and some analytical formulae, which I have introduced in order to define the numerical probability of particular word formations. In this way one can, for example, approximately determine the measure of confidence of a given etymology, and, depending on the proximity of this number to 1 and its confidence, one has to judge about the proposed authenticity. This is not the place to discuss details of this matter to with I merely wanted to draw the attention. But in order to directly explain in which way corresponding studies may find their way into the realm of applied mathematics, I regard it to reasonable to briefly point out some of the numerical assertions and materials which need to be elaborated. If we talk about a language, we predominantly assume that we have its detailed arithmetical description or, if we will, its statistics, i.e. numerical assertions about the complete inventory of the words of that language, about the distribution of these words according to the parts of speech, about the number of letters, about the initial letters, the endings, etc. etc. Also general rules have to be named here, exceptions of various kinds, words undoubtedly stemming from different languages, and the like. This is the numerical material the strict analysis of which quite naturally demands mathematical considerations. If one has the relevant statistical data as to two or more languages, one can compare them in various aspects, and the results obtained take the status of an authority which philologists, at the present state of science, do not use to have available. Of course the elaboration of what I have called the statistics of language is a very pains-taking endeavor, and most probably philologists will tend to call this kind of effort almost wasted, because the assumed gain of the exactness of the conclusions about language does not pay for the loss of time. We do not take on the responsibility of solving the question to which degree such an assertion may be justified. Maybe I will publish my theoretical studies on the matter which I have only mentioned here, at some other opportunity. However, as far as the practical applications of the general formulae are concerned, it will be necessary, given the general lack of detailed arithmetical data about languages, to confine oneself to a few examples. By the way, in order to devote the proper degree of completeness and soundness to such a work with regard to the philological conditions, it goes without saying that a mathematician has to establish direct contact with specialists in this field, more or less foreign to himself.”
