AMSEcast

On this episode of AMSEcast, host and American Museum of Science and Energy Executive Director Alan Lowe sits down with award-winning journalist Jeffrey Stern to discuss his widely successful book, "The Warhead: The Quest to Build the Perfect Weapon in the Age of Modern Warfare."

On this episode of AMSEcast, host Alan Lowe sat down with Lawrence Townsend to discuss the past, present, and future of America's nuclear navy, including what our advancements in technology throughout the country might mean going forward.

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.

Alan Lowe talks with Richard Munson about his book Ingenious: A Biography of Benjamin Franklin, Scientist. Munson's book aims to highlight Franklin's often overlooked scientific achievements. He describes Franklin's rise from a penniless runaway to a successful printer whose curiosity fueled his scientific breakthroughs. Franklin's experiments helped define core electrical concepts and led to inventions like the lightning rod, reflecting his Enlightenment commitment to reason and inquiry. His scientific fame later boosted his diplomatic mission in France, where his celebrity status helped secure essential support for American independence.

Author Simon Cordrey discusses the early days of the railroad and how that changed America.

Alan Lowe is joined in this episode of AMSEcast by Dr. Robin Andrews, volcanologist, science journalist, and author of How to Kill an Asteroid. Dr. Andrews explores how modern planetary defense blends cutting-edge detection networks, such as NASA's NEO Surveyor, with active deflection efforts like the DART mission, which successfully shifted an asteroid's orbit. He also delves into theoretical approaches, including gravity tractors and even nuclear options as last-resort strategies. While comets remain a tougher, faster-moving threat, advances in technology continue to make catastrophic impacts increasingly unlikely. Driven by a deep passion for the solar system's tangible wonders, Dr. Andrews continues to write and follow groundbreaking missions like NASA's Europa Clipper. About Dr. Robin Andrews: Dr. Robin Andrews is an experimental volcanologist, science journalist, and award-winning author whose work has appeared in Scientific American, National Geographic, The New York Times, and The Washington Post, including front-page stories in the latter two. He has frequently appeared on television programs such as Good Morning America and BBC News, and was awarded the 2022 David Perlman Award for Excellence in Science Writing by the American Geophysical Union. Robin's books include Super Volcanoes: What They Reveal about Earth and the Worlds Beyond and How to Kill an Asteroid: The Real Science of Planetary Defense, blending rigorous science with engaging storytelling.

Host Alan Lowe continues AMSEcast's exploration of 250 years of American innovation with Smithsonian experts Harold Wallace Jr., Dr. Eric Hintz, and Tim Pula. Together, they trace invention from Benjamin Franklin's experiments to modern breakthroughs, highlighting the Smithsonian's exhibitions, collections, and hands-on learning at Spark!Lab. The discussion spans collaboration with the Library of Congress, the role of failure in creativity, and how patents shape (but don't define) innovation. The guests also reflect on nuclear technology's history and social impact, and share how listeners can connect with the Lemelson Center and its nationwide Spark!Lab network inspiring inventors of all ages.
