Lithium, often called "white gold," is a critical resource powering modern technologies like electric vehicles (EVs), renewable energy storage, and more. This week, we explore lithium's geological formation, mining, processing, and its growing importance in the energy revolution. We also dive into exciting developments in Arkansas, which could make the U.S. a major player in domestic lithium production.

This week, we dive into the fascinating world of coal—its origins, types, and the role it has played in shaping economies, past and present. We discuss coal’s formation in ancient swampy environments, the journey from mining to electricity generation, and the transition we’re witnessing as the world moves toward renewable energy sources. We wrap up with a Fun Paper Friday that challenges the classic "Infinite Monkeys Theorem"—could monkeys really type out Shakespeare if given enough time?
