Author Michelle Shocklee discusses her novel The Women of Oak Ridge and the personal, historical, and emotional paths that led her to the story of the Secret City during the Manhattan Project. Growing up near Los Alamos and coming from a World War II family shaped her long-standing connection to the era, but a chance encounter with a reader ultimately sparked her discovery of Oak Ridge. Shocklee describes her deep research process, drawing on oral histories, archival photographs, museum resources, and firsthand accounts to authentically portray life inside a city built on secrecy. She explains how she weaves history into fiction by grounding the narrative in the lived experiences of her characters, particularly women whose wartime work reshaped their futures. The conversation highlights the challenges of secrecy, segregation, and stress faced by Oak Ridge residents, as well as the lasting impact of women entering the workforce during the war. Ultimately, Shocklee reflects on Oak Ridge as both a hidden chapter of history and a powerful source of human resilience and transformation.

In this episode of AMSEcast, host Alan Lowe welcomes back science journalist and NASA senior science writer James Riordon to discuss his new book Crush: Close Encounters With Gravity. Riordon explores the fascinating science of gravity, from Isaac Newton's groundbreaking laws to Albert Einstein's revolutionary theory of general relativity. The conversation dives into how gravity shapes everything from the structure of Earth to the behavior of black holes and gravitational waves. Riordon also explains the strange effects of weightlessness on the human body, the mysteries of dark matter and dark energy, and the possibility of exotic phenomena like wormholes. Blending history, physics, and cutting-edge discoveries, this episode offers an accessible look at one of the universe's most fundamental forces and the scientists who helped us understand it.

In this episode of AMSECast, Dr. Samantha Schrell explores the fascinating and often mysterious world of actinides—rare, radioactive elements with powerful applications in medicine, energy, space exploration, and national security. She explains what makes actinides unique, why they are difficult to study, and how elements like californium play a critical role in starting nuclear reactors and powering space missions. Dr. Schrell also discusses Oak Ridge National Laboratory's long-standing leadership in producing and researching heavy actinides through the High Flux Isotope Reactor. The conversation highlights the mission of the Glenn T. Seaborg Institute: building a pipeline of scientists and engineers trained to work in this highly specialized field. Through fellowships, collaboration across national labs, and cutting-edge research, the Institute is ensuring the future of actinide science. Ultimately, the episode reveals how curiosity, expertise, and education drive innovation at the atomic edge.

This episode explores how science education becomes an act of resilience, hope, and nation-building in Ukraine. From the creation of the country's first national science museum to mobile science labs traveling near the front lines, the Junior Academy of Sciences of Ukraine demonstrates how curiosity can endure even amid war. The guest traces a personal journey from law and political science into science education, driven by a commitment to Ukraine's future. Listeners learn how museums, labs, competitions, and business incubators form an educational "vertical" that guides children from first wonder to real-world innovation. The conversation highlights international collaboration, UNESCO recognition, and the global importance of engaging young minds in science. Ultimately, it's a powerful reminder that investing in knowledge is investing in peace, progress, and possibility.

In this wide-ranging conversation, Ahmed El-Mokadem explores the deep ideas behind mathematics' most mysterious numbers, revealing how concepts like zero, infinity, irrational numbers, and imaginary numbers challenge both logic and philosophy. He traces how constants such as π, e, the golden ratio, and the Feigenbaum constants appear universally across nature, physics, biology, and technology—suggesting they are discovered features of reality rather than human inventions. El-Mokadem highlights how mathematics repeatedly expands its own boundaries, from accepting imaginary numbers to assigning meaning to divergent infinities through Ramanujan's work. He shows that even chaos follows hidden numerical order, and that numbers long viewed as paradoxical often turn out to be indispensable. Throughout, mathematics emerges not as cold abstraction, but as a living language that reveals structure, mystery, and beauty in the universe. The discussion ultimately invites listeners to see math as a bridge between human curiosity and the deep order of the cosmos.

From Oak Ridge, Tennessee, AMSEcast host Alan Lowe sits down with geologist and paleontologist Dr. Jan Zalasiewicz, chair of the Anthropocene Working Group and author of How to Read a Rock. Their conversation explores how rocks and minerals form and what they reveal about Earth's history, from the rock cycle and earthquakes to ancient climates recorded in stone. Jan explains how life, human activity, and materials like bricks and concrete have reshaped geology, and how coal, oil, and gas fit into Earth's carbon cycle. The discussion also looks outward to the Moon and Mars, where rocks offer clues to planetary history and the possibility of past life. Guest Bio Dr. Jan Zalasiewicz is a geologist and paleontologist and an emeritus professor of paleobiology at the University of Leicester. He serves as chair of the Anthropocene Working Group, which has played a leading role in advancing the idea of the Anthropocene as a new geologic epoch shaped by humanity's impact on Earth. A prolific and widely published author, Jan explores how rocks, fossils, and landscapes record the planet's deep history. His books include The Cosmic Oasis: The Remarkable Story of Earth's Biosphere, Discarded: How Technofossils Will Be Our Ultimate Legacy, and How to Read a Rock: Our Planet's Hidden Stories, which is the focus of today's conversation.

What if I told you that, no matter where you are or what you are doing, about 100 trillion neutrinos are passing through your body every second? Well, you might first respond, as I did, by asking what is a neutrino, and then wondering why we seem to have no awareness at all of their presence. I mean, if were one or two particles, sure, you might miss them, but 100 trillion every second? I needed to learn more so I spoke on our podcast, AMSEcast, with Alan Chodos and James Riordon about their fascinating book, Ghost Particle: In Search of the Elusive and Mysterious Neutrino.

Ghost Particle explores the neutrino, one of the most abundant yet elusive particles in the universe, tracing its journey from a theoretical fix to puzzling nuclear reactions to a cornerstone of modern physics. The book explains how neutrinos helped preserve fundamental laws like conservation of energy and reveals how decades of ingenious experiments finally confirmed their existence. The authors guide readers through discoveries such as neutrino "flavors," oscillations, and the surprising realization that neutrinos have mass—challenging the Standard Model of particle physics. Cutting-edge research is connecting neutrinos to cosmic phenomena, including supernovae, the interior of the Sun, and the structure of the galaxy itself. Neutrinos may unlock answers to some of the universe's deepest mysteries, from the imbalance between matter and antimatter to the nature of dark matter and dark energy.

Around 66 million years ago, an asteroid that was perhaps 9 miles wide struck the Earth, an impact that led to the extinction of the dinosaurs. What if an asteroid that large or even larger was headed toward Earth today? We've seen this scenario in books and in movies like Armageddon, but I wanted to get some expert input, so I spoke on our podcast, AMSEcast, with Robin Andrews, about his book, How to Kill an Asteroid: The Real Science of Planetary Defense.
