Facing Infinity: Black Holes and Our Place on Earth
13/11/2025 Duration: 55minHumanity’s relationship with black holes began in 1783 in a small English village, when clergyman John Michell posed a startling question: What if there are objects in space that are so large and heavy that not even light can escape them? Almost 250 years later, in April 2019, scientists presented the first picture of a black hole. Profoundly inspired by that image, physicist Jonas Enander has traveled the world to investigate how our understanding of these elusive celestial objects has evolved since the days of Michell. With the particular goal of discovering our human connection to black holes, Enander visits telescopes and observatories, delves deeply into archives, and interviews over 20 world-leading experts, including several Nobel laureates. In Facing Infinity: Black Holes and Our Place on Earth (The Experiment, 2025), Dr. Enander takes us on a spellbinding journey into the universe’s greatest mystery, deciphers the most mind-bending science, and answers questions surrounding how black holes work,

Craig Hogan, "The Unlikely Primeval Sky" (American Scientist, November-December)
13/11/2025 Duration: 30minOf all the patterns that could possibly be preserved in the post–Big Bang radiation, the one we see is surprisingly smooth on large angular scales. Sitting by a campfire on a dark night, looking up at the Milky Way, a curious child asks, “What does the sky tell us? Where does it all come from? Does space go on forever?” A caring adult might share a little awe and humility about humanity’s place in the grand scheme or perhaps relate a traditional creation story. A scientist like me, who came of age soon after the discovery that the sky is not actually dark but awash in primeval radiation, might instead relate the still-unfinished scientific story of the boundaries and origins of time and space. That tale is displayed in nature’s own record of the structure of the early universe, a mosaic of temperature and density fluctuations preserved in the primordial light that astronomers call the cosmic microwave background (CMB).

Eduardo Mercado III, "Why Whales Sing" (JHU Press, 2025)
11/11/2025 Duration: 01h05minWith breathtaking complexity and haunting beauty, the songs of whales have long fascinated scientists. Whales are the only mammals that can sing continuously for ten hours or more, changing the unique songs they sing every year. In Why Whales Sing (JHU Press, 2025), bioacoustician and cognitive scientist Eduardo Mercado transforms our understanding of these enigmatic sounds and proposes a groundbreaking theory that challenges decades of established science. Fifty years of field research have led most scientists to conclude that humpback whales sing for the same reason that birds do: to advertise their sexual fitness. But if whale songs are nothing more than tools of attraction, why do whales sing even when they're alone and there are no listeners nearby? In light of modern advances in neuroscience and ocean acoustics, Mercado reaches the surprising conclusion that whales may not actually be "singing," but rather engaging in an activity more commonly associated with dolphins and bats--echolocating--which en

Marcus Chown, "A Crack in Everything: How Black Holes Came in from the Cold and Took Cosmic Centre Stage" (Apollo, 2025)
07/11/2025 Duration: 01h17minWhat is space? What is time? Where did the universe come from? The answers to mankind's most enduring questions may lie in science's greatest enigma: black holes.A black hole is a region of space where gravity is so strong that nothing, not even light, can escape. This can occur when a star approaches the end of its life. Unable to generate enough heat to maintain its outer layers, it shrinks catastrophically down to an infinitely dense point.When this phenomenon was first proposed in 1916, it defied scientific understanding so much that Albert Einstein dismissed it as too ridiculous to be true. But scientists have since proven otherwise. In 1971, Paul Murdin and Louise Webster discovered the first black hole: Cygnus X-1. Later, in the 1990s, astronomers using NASA's Hubble Space Telescope found that not only do black holes exist, supermassive black holes lie at the heart of almost every galaxy, including our own. It would take another three decades to confirm this phenomenon. On 10 April 2019, a team of astr

Liam Graham, "Physics Fixes All the Facts" (Springer Nature, 2025)
05/11/2025 Duration: 46minComplex systems seem to magically emerge from the interactions of their parts. A whirlpool emerges from water molecules. A living cell from organic molecules. You emerge from the cells of your body. Not since chaos has a concept from physics spread like wildfire to other disciplines. Emergence can be found from chemistry to economics; from psychology to ecology. At its heart is the alluring idea that there's more to the world than physics, that there is a holistic component to nature, an edge of mystery. "Physics Fixes All the Facts" starts by taking you on a tour through a fascinating world of complexity, exploring phenomena from the inside of an atomic nucleus to bacterial behaviour to the ability of your thoughts to affect the world. These examples are used along with a thorough exploration of the philosophical literature to untangle the notoriously poorly defined concept of emergence. This reveals something surprising: the term emergence is redundant. In its weak form it is so weak that it applies to eve

Vlatko Vedral, "Portals to a New Reality: Five Pathways to the Future of Physics" (Basic Books, 2025)
31/10/2025 Duration: 01h14minFor the last century, physics has been treading along the paths set by the same two theories--quantum theory and general relativity--and, let's face it, it's getting pretty boring. Most scientists are simply chasing decimal points in laboratories, unable to explore the theories at large scales, where serious discrepancies could emerge. The situation is a lot like the one physics was in in 1890, right before Planck, Einstein, and Bohr blew the roof off Newtonian physics. As Vlatko Vedral argues in Portals to a New Reality: Five Pathways to the Future of Physics (Basic Books, 2025), that means we are on the brink of a revolution. Vedral shows how quantum information theory has opened radically new avenues for experiments that could upend physics. They can sound very strange--one essentially involves entangling a human with Schrödinger's cat--but they lay bare elements of our theories that are particularly problematic, such as the widespread belief that nothing truly exists unless it is observed. At present th

Brian Potter, "The Origins of Efficiency" (Stripe Press, 2025)
28/10/2025 Duration: 51minEfficiency is the engine that powers human civilization. It's the reason rates of famine have fallen precipitously, literacy has risen, and humans are living longer, healthier lives compared to preindustrial times. But where do improvements in production efficiency come from? In The Origins of Efficiency (Stripe Press, 2025), Brian Potter argues that improving production efficiency--finding ways to produce goods and services in less time, with less labor, using fewer resources--is the force behind some of the biggest and most consequential changes in human history. With unprecedented depth and detail, Potter examines the fundamental characteristics of a production process and how it can be made less time- and resource-intensive, and therefore less expensive. The book is punctuated with examples of production efficiency in practice, including how high-yield manufacturing methods made penicillin the "miracle drug" that reduced battlefield infection deaths by 80 percent during World War II; the 100-year his

Rick A López, "Rooted in Place: Botany, Indigeneity, and Art in the Construction of Mexican Nature, 1570-1914" (U Arizona Press, 2025)
28/10/2025 Duration: 50minSince the first moment of conquest, colonizers and the colonized alike in Mexico confronted questions about what it meant to be from this place, what natural resources it offered, and who had the right to control those resources and on what basis. Focusing on the ways people, environment, and policies have been affected by political boundaries, in Rooted in Place: Botany, Indigeneity, and Art in the Construction of Mexican Nature, 1570–1914 (University of Arizona Press, 2025) historian Dr. Rick A. López explores the historical connections between political identities and the natural world. Dr. López analyzes how scientific intellectuals laid claim to nature within Mexico, first on behalf of the Spanish Empire and then in the name of the republic, during three transformative moments: the Hernández expedition of the late sixteenth century; the Royal Botanical Expedition of the late eighteenth century; and the heyday of scientific societies such as the Sociedad Mexicana de Historia Natural of the late nineteent

Roger Moorhouse, "Wolfpack: Hitler’s U-Boat War 1939-45" (HarperCollins, 2025)
26/10/2025 Duration: 01h05minWinston Churchill famously remarked that the threat of the German U-Boats was the only thing that had “really frightened” him during World War Two. The U-Boats certainly claimed a bitter harvest among Allied shipping: nearly 3,000 ships were sunk, for a total tonnage of over 14 million tonnes, nearly 70% of Allied shipping losses in all theatres of the war. With justification, then, they are an integral part of the traditional narrative of the Battle of the Atlantic; a story of technological brilliance, dramatic sinkings, life and death, and – of course – the sinister, unseen threat of the U-Boats themselves. For Allied seamen during the war, the U-Boat was a hidden menace, a faceless killer lurking beneath the waves; and the urgent needs of survival afforded them little time or energy to consider the challenges and privations of their enemy. History, however, affords us that time and energy, and any pretence of comprehensiveness demands that we consider what life was like for the crews of those most claustr

Harry Cliff, "Space Oddities: The Mysterious Anomalies Challenging Our Understanding of the Universe" (Doubleday, 2024)
24/10/2025 Duration: 01h06minNothing captivates the human imagination like the vast unknowns of space. Ancient petroglyphs present renderings of the heavens, proof that we have been gazing up at the stars with wonder for thousands of years. Since then, mankind has systematically expanded our cosmic possibilities. What were once flights of fancy and dreams of science fiction writers have become nearly routine – a continuous human presence orbiting the Earth, probes flying beyond our solar system, and men walking on the moon. NASA and the Russian space program make traveling to the stars look easy, but it has been far from that. Space travel is a sometimes heroic, sometimes humorous, and always dangerous journey fraught with perils around every corner that most of us have never heard of or have long since forgotten.Space Oddities: The Mysterious Anomalies Challenging Our Understanding of the Universe (Doubleday, 2024) brings these unknown, offbeat, and obscure stories of space to life. From the showmanship and bravado of the earliest known

Alice Lovejoy, "Tales of Militant Chemistry: The Film Factory in a Century of War" (U California Press, 2025)
23/10/2025 Duration: 45minThe history of film calls to mind unforgettable photographs, famous directors, and the glitz and hustle of the media business. But there is another tale to tell that connects film as a material to the twentieth century's history of war, destruction, and cruelty. This story comes into focus during World War II at the factories of Tennessee Eastman, where photographic giant Kodak produced the rudiments of movie magic. Not far away, at Oak Ridge, Kodak was also enriching uranium for the Manhattan Project--uranium mined in the Belgian Congo and destined for the bomb that fell on Hiroshima. While the world's largest film manufacturer transformed into a formidable military contractor, across the ocean its competitor Agfa grew entangled with Nazi Germany's machinery of war. After 1945, Kodak's film factories stood at the front lines of a new, colder war, as their photosensitive products became harbingers of the dangers of nuclear fallout. Following scientists, soldiers, prisoners, and spies through Kodak's and Agf

Jeffrey D. Sharon, "The Great Balancing Act: An Insider's Guide to the Human Vestibular System" (Columbia UP, 2025)
21/10/2025 Duration: 01h07minWhat's the secret to keeping your balance? The ear does more than hear: it helps us stay stable by perceiving movements and gravity. Elegant sensors deep within the skull detect every twist, turn, and tumble, powering swift reflexes that keep vision and balance steady. This is the vestibular system. It's primordial and ubiquitous: every animal has one, and even plants have a rudimentary version. It works so well that we take it for granted--until it fails. How does this remarkable system function? What happens when it goes haywire? How can modern medicine treat vestibular disease? The Great Balancing Act: An Insider's Guide to the Human Vestibular System (Columbia UP, 2025) tells the story of the vestibular system, from T. rex hearing organs to cochlear implants, and from the unsung power of hair cells to inner-ear problems in outer space. Combining neuroscience, history, and medicine, Jeffrey D. Sharon--a vestibular doctor and researcher--explains the sense of balance using accessible language and wry humo

David Bressoud, "Calculus Reordered: A History of the Big Ideas" (Princeton UP, 2019)
19/10/2025 Duration: 01h27minCalculus Reordered: A History of the Big Ideas (Princeton UP, 2019) takes readers on a remarkable journey through hundreds of years to tell the story of how calculus evolved into the subject we know today. David Bressoud explains why calculus is credited to seventeenth-century figures Isaac Newton and Gottfried Leibniz, and how its current structure is based on developments that arose in the nineteenth century. Bressoud argues that a pedagogy informed by the historical development of calculus represents a sounder way for students to learn this fascinating area of mathematics. Delving into calculus’s birth in the Hellenistic Eastern Mediterranean—particularly in Syracuse, Sicily and Alexandria, Egypt—as well as India and the Islamic Middle East, Bressoud considers how calculus developed in response to essential questions emerging from engineering and astronomy. He looks at how Newton and Leibniz built their work on a flurry of activity that occurred throughout Europe, and how Italian philosophers such as Galil

Caleb Scharf, "The Giant Leap: Why Space Is the Next Frontier in the Evolution of Life" (Hachette UK, 2025)
17/10/2025 Duration: 01h21minA leading astrobiologist "demonstrates how becoming a true space-faring species is more than just humanity's future" (Adam Frank, author of The Little Book of Aliens)--it is an evolutionary event at least as important as life's first journey from sea to land The story of life has always been one of great transitions, of crossing new frontiers. The dawn of life itself is one; so, too, is the first time two cells stuck together rather than drifting apart. And perhaps most dramatic were the moves from the sea to land, land to air. Each transition has witnessed wild storms of innovation, opportunity, and hazard. It might seem that there are no more realms for life to venture. But there is one: space. In The Giant Leap: Why Space Is the Next Frontier in the Evolution of Life (Hachette UK, 2025), astrobiologist Caleb Scharf argues that our journey into space isn't simply a giant leap for humankind--it's life's next great transition, an evolution of evolution itself. Humans and our technology are catalysts for an

Allen B. Downey, "Probably Overthinking It: How to Use Data to Answer Questions, Avoid Statistical Traps, and Make Better Decisions" (U Chicago Press, 2023)
10/10/2025 Duration: 01h02minStatistics are everywhere: in news reports, at the doctor's office, and in every sort of forecast, from the stock market to the weather. Blogger, teacher, and computer scientist Allen B. Downey knows well that people have an innate ability both to understand statistics and to be fooled by them. As he makes clear in this accessible introduction to statistical thinking, the stakes are big. Simple misunderstandings have led to incorrect medical prognoses, underestimated the likelihood of large earthquakes, hindered social justice efforts, and resulted in dubious policy decisions. There are right and wrong ways to look at numbers, and Downey will help you see which are which. Probably Overthinking It: How to Use Data to Answer Questions, Avoid Statistical Traps, and Make Better Decisions (University of Chicago Press, 2023) uses real data to delve into real examples with real consequences, drawing on cases from health campaigns, political movements, chess rankings, and more. He lays out common pitfalls--like the

Gerta Keller, "The Last Extinction: The Real Science Behind the Death of the Dinosaurs" (Diversion Books, 2025)
04/10/2025 Duration: 59minThe story behind Dr. Gerta Keller’s world-shattering scientific discovery that dinosaur extinction was NOT caused by asteroid impact, but rather by volcanic eruptions on the Indian peninsula, a discovery that highlights today’s existential threat of greenhouse gasses and climate change—and one that sparked an all-out war waged by the scientific establishment.Part scientific detective story, part personal odyssey, The Last Extinction: The Real Science Behind the Death of the Dinosaurs (Diversion Books, 2025) is the definitive account of a radical theory that has reshaped how we understand our planet’s past and, as we face the possibility of a sixth extinction, how we might survive its future.For decades, the dominant theory held that an asteroid impact caused the dinosaurs’ extinction. But Princeton Geologist Dr. Gerta Keller followed the evidence to the truth: Deccan volcanism, a series of massive volcanic eruptions in India, triggered a long-term climate catastrophe and Earth’s fifth mass extinction.

Daniel K. Sodickson, "The Future of Seeing: How Imaging is Changing the World" (Columbia UP, 2025)
03/10/2025 Duration: 01h09minOver the centuries, we have learned to peer into what was once invisible. Imaging devices like cameras, telescopes, microscopes, and MRI machines map the world around, beyond, and within us in ways the naked eye could never see. In so doing, these technologies have transformed our understanding of our place in the universe and our conception of our own bodies--and we may be on the cusp of an even greater revolution. Daniel K. Sodickson--a physicist and biomedical imaging innovator--explores the rich history and surprising future of vision, from the evolution of eyes to emerging high-tech devices. Beginning in the early oceans, when organisms first developed sight, The Future of Seeing: How Imaging is Changing the World (Columbia UP, 2025) tells the stories of the many remarkable tools people have invented to extend our natural vision. Ranging from the tales of brilliant inventors to profiles of everyday people, this book shows how imaging has transformed the practice of medicine, reshaped the global economy,

157 Mangrum's Comical Computation (JP)
02/10/2025 Duration: 46minWhen does comedy become more than a laugh? Ben Mangrum of MIT joins RtB to discuss his new book, The Comedy of Computation: Or, How I Learned to Stop Worrying and Love Obsolescence (Stanford UP, 2025), which in some ways is organized around “the intriguing idea that human knowledge work is our definitive feature and yet the machines we are ourselves made are going to replace us at it.” Comedy has provided a toolbox (Charles Tilly calls them "collective repertoires") for responding to the looming obsolescence of knowledge workers.John's interest in Menippean satire within science fiction leads him to ask about about the sliding meanings of comedy and its pachinko machine capacity; he loves the way Ben uses the word and concept of doubling,; Ben explains how the computer may either queer (in an antisocial way) or get assimilated into romantic heteronormative pairings. John asks about Donna Haraway’s 1985 A Cyborg Manifesto and teh way it denaturalizes gender roles and the way new technological affordances (fro

Mark Vellend, "Everything Evolves: Why Evolution Explains More than We Think, from Proteins to Politics" (Princeton UP, 2025)
27/09/2025 Duration: 01h05minHow the science of evolution explains how everything came to be, from bacteria and blue whales to cell phones, cities, and artificial intelligence Everything Evolves: Why Evolution Explains More Than We Think, from Proteins to Politics (Princeton UP, 2025) reveals how evolutionary dynamics shape the world as we know it and how we are harnessing the principles of evolution in pursuit of many goals, such as increasing the global food supply and creating artificial intelligence capable of evolving its own solutions to thorny problems. Taking readers on an astonishing journey, Mark Vellend describes how all observable phenomena in the universe can be understood through two sciences. The first is physics. The second is the science of evolvable systems. Vellend shows how this Second Science unifies biology and culture and how evolution gives rise to everything from viruses and giraffes to nation-states, technology, and us. He discusses how the idea of evolution had precedents in areas such as language and econo
