Paul Erdős — Le mathématicien sans maison qui a bâti un empire de savoir | Documentaire biographique

Paul Erdős was undoubtedly the most singular figure in the history of 20th-century mathematics. Born in Budapest in 1913, on the very days his parents lost their two daughters, raised away from school by a mother consumed by fear, he became the author of the most extensive body of scientific work ever produced by a single person. Nearly 1,500 articles, 511 direct co-authors—a record that no one will likely ever break. And, for sixty years, he had neither a house, nor a steady job, nor a bank account. This documentary retraces the entire life of this extraordinary man. The childhood of a prodigy who discovered negative numbers on his own before he knew how to tie his shoelaces. The university years under the numerus clausus, the Hungarian law of 1920 that closed the doors of universities to an entire generation and, paradoxically, gave rise to one of the most brilliant cohorts of scientists in European history. The departure for Manchester, then for Princeton, on the eve of the war. The loss of most of his family during the occupation of Hungary, and the absolute silence he maintained throughout his life about this loss. We also recount the major controversies of his career: the Selberg affair and the elementary proof of the prime number distribution theorem, this major result established in 1896 by the Frenchman Jacques Hadamard and the Belgian Charles de la Vallée Poussin. The nine years during which the United States refused him entry, while the authorities of his own country watched him with equal suspicion. We have chosen to present these contested episodes by outlining the different versions of events, without taking sides where historians of science do not. The film also addresses the substance of his work, explained without any jargon and accessible to any curious viewer. Ramsey's theory and the idea that beyond a certain size, complete disorder becomes impossible. The probabilistic method, which proves the existence of an object without ever constructing it. The theory of random graphs, founded with Alfred Rényi. The Anning-Erdős theorem on integer distances, whose proof fits on a single page and requires nothing more than the geometry of the ancient Greeks. And that very particular conviction that guided his entire life as a researcher: the idea of ​​a Book containing the perfect proofs of all true theorems. Finally, this documentary focuses on the man himself. The hundreds of families who took him in around the world. Ronald Graham and Fan Chung, who kept his accounts for over thirty years. The problems with accompanying prizes, whose checks ended up framed in professors' offices. The gifted children he called his epsilons, among them a ten-year-old Australian boy named Terence Tao. His mother, who boarded a plane for the first time at eighty-four and accompanied him for seven years across four continents. And that last night in September 1996, in a Warsaw hotel, where the man who had more friends than any other mathematician in history passed away alone. A complete biography, documented and told with a constant concern for historical accuracy, for an audience curious about science, twentieth-century European history, and extraordinary lives.
