        A Fission Chain Reaction

        In this video excerpt from NOVA: "Hunting the Elements," New York Times technology columnist David Pogue investigates the radioactive elements located at the bottom of the periodic table. Discover how scientists once thought that uranium was the end of the periodic table and find out how the table has grown since atomic scientists created synthetic elements. Visit the Nuclear Museum in New Mexico to learn about the process of nuclear fission and to see a demonstration of what happens inside a nuclear reactor.

        This video is available in both English and Spanish audio, along with corresponding closed captions.
