The path to nuclear fission

WebbThe Path to Nuclear Fission is about a brilliant Jewish woman, who would make scientific history when she and her colleague Otto Hahn discovered nuclear fission in 1938 in Berlin. It was a discovery that lead to the invention of the atomic bomb. This film, narrated by Linda Hunt, tells her story for the first time. Directors Rosemarie Reed Starring WebbNuclear fission is a fascinating field of research that involves large-amplitude collective dynamics of a microscopic many-body system. Specifically, the process of spontaneous-fission decay can only be explained within the quantum tunneling phenomenon.
