Tracing uranium's past—and how it intersects with our understanding of other radioactive elements—Chain Reactions aims to enlighten readers and refresh our attitudes about the atomic world. Chain Reactions 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.
