Adventures of a Mathematician, directed by Thor Klein,is a biopic of Stan Ulam (played by Philippe Tlokinski), whose mathematics worked out the formula to produce the atomic bomb at Los Alamos during World War II. Although Klaus Fuchs, Robert Oppenheimer, and Edward Teller are better known members of the Manhattan Project and are indeed featured in the film, the focus is on Ulam, who experiences little joy and much regret throughout his life. A Polish Jew who immigrated to the United States in the 1930s, he believes that his participation is needed for the United States to develop the atomic bomb before the Nazis. But he is unhappy when the bomb is used against Japan. Nevertheless, he later works to develop the hydrogen bomb before the Soviet Union. Most of the film focuses on his relations with relatives, infighting at Los Alamos, and his personal anxieties. MH
