Ionescu-Tulcea theorem

In the mathematical theory of probability, the Ionescu-Tulcea theorem, sometimes called the Ionesco Tulcea extension theorem deals with the existence of probability measures for probabilistic events consisting of a countably infinite number of individual probabilistic events. In particular, the individual events may be independent or dependent with respect to each other. Thus, the statement goes beyond the mere existence of countable product measures. The theorem was proved by Cassius Ionescu-Tulcea in 1949. (Wikipedia).

Fubini Counterexample

Fubini's theorem states that, under certain assumptions, the double integral of f(x,y) dx dy is equal to the double integral of f(x,y) dy dx. In this video, I give an example where Fubini's theorem does NOT apply, by explicitly showing that for a specific function, the two integrals are un

Reinventing Cavalry in WW1 - Bulgarian General Ivan Kolev I WHO DID WHAT IN WW1?

Cavalry was seen as leftover from the past in the dawn of modern warfare during World War 1. But Bulgarian General Ivan Kolev was one of the few who still saw a place for them on the modern battlefield. He reinvented the cavalry role and used them together with early motorised infantry - w
