July 19, 2025Jul 19 Just listened to this podcast about Clair Patterson (who calculated the age of the Earth) and thought it was interesting. Description from Youtube: From the Radiolab podcast: After helping to create the atomic bomb, chemist Clair Patterson embarks on a quest of redemption to stop humanity from quietly poisoning the planet. In this episode we have a story about the sometimes obvious but sometimes sneaky effects of the way that we humans rearrange the elemental stuff around us. Reporter Avir Mitra brings us a story about how Clair Patterson's relentless pursuit of a deep truth about the Earth led to an obsession with lead that really changed the very air we breathe.
