Very much off-topic: I understand the post and the present discussion are not about Kolmogorov's scientific work, but I could not resist pointing out that in addition to all the great things Scott mentioned, Kolmogorov also made significant contributions to fluid turbulence (https://en.wikipedia.org/wiki/Turbulence#Kolmogorov.27s_theo...) and linear filtering (https://en.wikipedia.org/wiki/Wiener_filter#History), among many, many other things.
