Christopher Nolan's epic new film "Oppenheimer" is no mere biopic… nor is it the first attempt to capture the father of the atomic bomb in fiction. We look at prior dramatizations of this very complicated man—including one wherein J. Robert Oppenheimer played himself!—and examine why they worked or didn't. In this episode: Physicist-turned-photographer Minesh Bacrania shares his experience photographing inside the top-secret labs at Los Alamos National Laboratory, where J. Robert Oppenheimer and other scientists created the first nuclear weapon. Next, with Christopher Nolan’s film Oppenheimer exceeding commercial expectations, Smithsonian magazine writer Andy Kifer discusses the complexities of Oppenheimer's genius and how prior attempts to depict him in film and television and on stage have fared.

Four decades ago, Pablo Escobar brought to his Medellín hideaway four hippopotamuses, the centerpieces of a menagerie that included llamas, cheetahs, lions, tigers, ostriches and other exotic fauna. After Colombian police shot Escobar dead in December 1993, veterinarians removed the animals—except the hippos, which were deemed too dangerous to approach. The hippos fled to the nearby Magdalena River and multiplied.  Today, the descendants of Escobar’s hippos are believed to number nearly 200. Their uncontrolled growth threatens the region’s fragile waterways. Smithsonian contributor Joshua Hammer joins us to recount this strange history and explain why Colombian conservationists have embarked upon an unusual program to sterilize these hippos in the wild via “invasive surgical castration,” a procedure that is, as he has written (https://www.smithsonianmag.com/science-nature/pablo-escobar-abandoned-hippos-wreaking-havoc-colombian-jungle-180984494/) for Smithsonian magazine, “medically complicated, expensive and sometimes dangerous for hippos as well as for the people performing it.” Then, ecologist Rebecca Lewison tells us how her long-term study of hippo populations in Africa offers hints of how these creatures will continue to alter the Colombian ecosystem—and what authorities can do about it.
