Adventures of a Mathematician

Adventures of a Mathematician (2021) is a biographical drama you can watch online on iFILM, directed by Thorsten Klein and produced across Germany, the United Kingdom and Poland. It follows Stan Ulam — brought to life by Philippe Tłokiński — a Polish-born mathematician who left Europe in 1936, long before the continent collapsed into war.

His father and sister did not make it out. Carrying that grief, Ulam lands in Los Alamos, recruited by John von Neumann into the Manhattan Project. The film's quiet tension comes from watching a man who excels at pure abstraction now turning those skills toward the hydrogen bomb — the most destructive object his civilization has produced. Esther Garrel plays his wife; his brother escaped to Harvard and thrives, which makes the contrast harder to bear.

Thorsten Klein avoids both hagiography and thriller mechanics. What remains is something closer to a reckoning: a scientist who helped end the world's innocence, as the tagline puts it, while privately mourning the family the world already took from him.
