Do you want to know how to build a nuclear bomb? Are you curious why centrifuges are so important in international diplomacy? Did you know that a single nuclear weapon can explode with the same energy as all explosives used in World War 2 combined? Why should we care about countries getting nuclear weapons, anyways? In this course, we'll review the history of nuclear weapons, talk about the art and science of designing them, and see what the effects these weapons have had on the world. We'll also cover the current state of nuclear weapons and what you should know about modern scientific and political discussions about them. By the end of this class you'll know how to design a nuclear weapon but also understand the human risks and costs.
