Chain Reaction**s looks at the fascinating, often-forgotten stories that can be found throughout the history of uranium. From glassworks to penny stocks; from medicines to atomic weapons; from something to be feared to a powerful source of energy, this global history explores the scientific narrative of this unique element, but also shines a light on its cultural and social impact. By understanding our nuclear past, we can move beyond the ideological opposition to technologies and encourage a more nuanced dialogue about whether it is feasible—and desirable—to have a genuinely nuclear-powered future.
