Wolfgang Doeblin, one of the great probabilists of the 20th century, was already widely known in the 1950s for his fundamental contributions to the theory of Markov chains. His coupling method became a key tool in later developments at the interface of probability and statistical mechanics. But the full measure of his mathematical stature became apparent only in 2000 when the sealed envelope containing his construction of diffusion processes in terms of a time change of Brownian motion was finally opened, 60 years after it was sent to the Academy of Sciences in Paris ...

A man with no home and no job, Paul Erdös was the most prolific mathematician who ever lived. A wandering genius, Erdös, who died in 1996 at the age of 83, spent his life engaged in a cosmic struggle to uncover truths hidden by a stubborn adversary - God. In N is a Number he describes this metaphysical duel with the same wry humor he applied to politics, relationships and death. The documentary follows him through four countries to discover what makes mathematicians tick. N is a Number presents Erdös' mathematical quest, its personal and philosophical dimensions, and the tragic historical events that molded his life ...
