Have you ever thought about the science and history of … wind?

In this episode, Simon Winchester explains why eastbound flights are usually faster than flying west, and how the discovery of the jet stream was almost missed because the original research was published in Esperanto. He also talks about the debate over the Great Terrestrial Stilling—the idea that global wind speeds may be decreasing—and why newer measurements suggest the trend may be reversing.

Winchester describes how and where the highest wind speed ever recorded was measured, the increasing frequency of clear-air turbulence (the kind that causes sudden drops during flights), why only one flag placed on the Moon fell, the techniques used by Polynesian navigators to cross vast stretches of ocean without instruments, and the challenges faced by early wartime pilots who unintentionally flew into the jet stream.

Simon Winchester is the acclaimed author of many books, including The Professor and the Madman, which was adapted into a film starring Mel Gibson and Sean Penn, as well as The Men Who United the United States, The Map That Changed the World, The Man Who Loved China, A Crack in the Edge of the World, and Krakatoa. His books have been New York Times bestsellers and have appeared on numerous best-of-the-year lists. In 2006 he was appointed an Officer of the Order of the British Empire (OBE) by Her Majesty the Queen.

In this episode, Angus Fletcher explains why the human brain doesn’t work like a computer and why our deepest strengths come not from logic or data processing but from imagination, emotion, and the ability to invent new futures. Drawing on neuroscience, Shakespeare, evolutionary biology, and his work with U.S. Army Special Operations, Fletcher shows how storytelling is the brain’s oldest “technology,” why intelligence is rooted in action rather than analysis, and what most people get wrong about creativity and common sense.

Angus Fletcher is a professor of story science at Ohio State’s Project Narrative, the world’s leading academic think tank dedicated to understanding how stories work. He earned his PhD from Yale, conducted postdoctoral research at Stanford, and in 2023 received the U.S. Army’s Commendation Medal for his groundbreaking work with Army Special Operations on primal intelligence. He has also written screenplays for major Hollywood studios and networks. His new book is Primal Intelligence: You Are Smarter Than You Know.

War begins in the human mind long before it unfolds on the battlefield.

In this episode, Michael Shermer sits down with Nicholas Wright, a neurologist, neuroscientist, security strategist, and advisor to the Pentagon, to explore one of the biggest questions of our time: why do humans fight, and how does the brain shape violence, leadership, and geopolitical decision-making?

Nicholas Wright is a member of the Royal Colleges of Physicians and a neuroscientist who researches the brain, technology, and security at University College London, Georgetown University, and the Center for Strategic and International Studies in Washington, DC. He worked as a neurology doctor in London and Oxford, and has published numerous academic papers which have been covered by the BBC and The New York Times. His new book is Warhead: How the Brain Shapes War and War Shapes the Brain.
