"One cannot understand a nation without knowing its language"
Norbert Wiener
As Norbert's father (Leo Wiener) was a professor of Slavic languges born in Bialystok, and educated in Minsk and Warsaw, had a very good coommand of Russian language, His son also learned very easily foreign languages and liked to speak with his interlocutors in their native languages. So, they probably talked with Andrey Nikolaevich Kolmogorov in Russian.
Correct answer. Norbert Wiener arrived to the USSR during the Stalin period. Then was considered that geneticists are "the enemies of mankind from the"pea laws of monk G. Mendel"", and the cybernetics was considered "as a pseudo science from ("I am a genius" – N.W.) Wiener". When N. Wiener arrived to Russia to ("I am a mathematician" - A. Kolmogorov) Andrey Kolmogorov to discuss mathematical questions, Kolmogorov didn't accept him. Therefore N. Wiener never in any language didn't talk to A. Kolmogorov.
your question is excellent for its originality as well as your perfect answer in КВН style with anachronistic miths. However I’m sure, not everybody understands your joke like András Györfi.
Stalin died in 1953. Wiener visited the Moscow IFAC in 1960.
The reason of this “no-meeting” was another. Sure, we should respect Kolmogorov's choice. The forth Order of Lenin (1961) wasn't his dream ). Etiquette requires speaking the language of our guest. I doubt very much that W. and K. could be left alone. W. as an American researcher was accompanied by a Russian-English interpreter according the rules of that time.
