How Did Humans Ever Discover Uranium?

Most people picture uranium inside reactors, weapons, or laboratories. But humans were using uranium compounds long before anyone knew they were radioactive. So how did an unwanted black mineral become one of the most consequential materials humans ever learned to understand? This video follows that strange chain of discovery — from pitchblende and glowing uranium glass to an experiment that worked in total darkness, natural nuclear reactions deep underground, and the discovery of nuclear fission. In this video, you'll learn: why uranium was used before humans understood radioactivity how Martin Klaproth identified a new element in pitchblende how Henri Becquerel discovered uranium's invisible radiation why the Oklo uranium deposit changed what we thought nature could do how nuclear fission turned an old mineral into a new kind of power Sources: Royal Society of Chemistry — Uranium; Henri Becquerel's Nobel Lecture; International Atomic Energy Agency — Oklo natural reactors; U.S. Department of Energy — Nuclear Fission.
