In 1949, the California Academy of Sciences furthered its longstanding mission to engage and educate the public in the sciences by expanding to the media of television. The result was "Science in Action." a half-hour program on a specific scientific topic, presented by the Academy's then curator of the Steinhart Aquarium, Earl S. Herald, in tandem with an expert on the show's subject. Over its sixteen year run, the show included interviews with several Nobel Laureates. This is Episode 126, "The Magic of Metals" of the 'Science in Action' television program and features guest scientist Emo D. Porro from the Stanford Research Institute.
