How do undersea cables work and what is their significance in our daily lives? Samanth Subramanian, an award-winning journalist tells us about "fragile cables that connect our world" in his brilliant new book, "The Web Beneath the Waves". They operate behind the scenes and on the sea bed. Over 600 of them carry around 95 per cent of the world's intercontinental traffic. Unlike satellites which get a lot of press, submarine cables are largely unsung until something goes wrong. Take Ghana's stock exchange which, in 2024, had to shut down an hour earlier than scheduled after seismic activity severed some cables. In 2024 Houtis, a rebel group in Yemen, bombed a cargo ship, whose anchor was said to have damaged three cables. And then there's the occasional shark bite too. With barely 69 or so repair ships out there, the entire process of fixing these cables "is delightfully Victorian", says Samanth. We live in an era that this piece of technology holds enormous geopolitical clout too. His research, for his slim book, took him to some of the most unexpected places. The Economist named it as among the best books of 2025.

In this podcast Adam Weymouth, one of the most compelling young writers in the UK, talks about his latest book, "Lone Wolf: Walking the Line Between Civilization and Wildness". It's an immersive reportage that follows the journey of a wolf across Europe. Through encounters with farmers, hunters and rural communities, Adam examines how wolves have become a proxy for deeper anxieties about migration, economic decline and political control. What is a wolf? How does it think? What are some of the myths and realities of this beautiful animal? Adam takes us through what he learned in his peripatetic excursion to the sticks, which was as physically demanding as it was revealing.

How does it feel to stay in a cabin in Alaska? How does one keep their wits about oneself in places like the Arctic when the sun doesn't rise for 65-70 days during polar nights? And before you know it, daylight is back for 24 hours. Kieran Mulvaney has traveled to these lands for over 25 years. His latest book, "Arctic Passages: Ice, Exploration, and the Battle for Power at the Top of the World" is a personal account flush with rich reporting from frigid climes. In this podcast he talks about his experiences of visiting these remote lands, some of the crucial geopolitical implications of melting ice, why global warming is real and how the glacial pace at which we are responding isn't doing us any favours. The Economist has named Kieran's book as among the best non-fiction reads of 2025.

Cricket, globalisation, Trump's tariff tantrums, quirks of the English language, jargons and philosophy. This podcast covers some ground as award winning journalist Philip Coggan joins us to talk about his book, "The Economic Consequences of Mr Trump". He explains why tariffs are essentially taxes on imports that often raise costs for domestic producers, fail to meaningfully reduce trade deficits and can even slow growth and job creation. We live in an increasingly connected world. Our laptops and phones have components from various countries which makes these things efficient and affordable. The conversation also veers into the English language itself where it can do away with financial jargons or tautologies like "safe haven". Philip also talks about the art of storytelling and why he enjoys writing.

In this podcast Sir John Kay, one of the most original economic thinkers of our time, talks about what companies often get wrong. Drawing from his latest book, The Corporation in the Twenty-First Century: Why Almost Everything We Are Told About Business Is Wrong, he argues that chasing money instead of meaning is the first folly of modern corporations. Often times they focus far more than is necessary on quarterly numbers. Buzzwords like "maximising shareholder value" look great on power point slides. "No one has an epitaph on their grave that said he maximized shareholder value", he says. He shares many examples where behemoths disappeared gradually and then suddenly after shifting their purpose to maximising shareholder value. The conversation also turns to ethics. He quotes Atticus Finch from To Kill a Mocking Bird - "I can't behave one way at home and another in town" addressing that the company and the individual shouldn't have different moral codes. "There isn't a separation in my mind between ethics and morality as applied to business and ethics and morality as applied to life. They are one and the same".

Turning jargons and complex spagetti-like subjects into simple (but not simplistic) language is an art that few authors can pull off. Edward Fishman is one of them. His book, "Chokepoints: American Power in the Age of Economic Warfare", a New York Times Bestseller, explains something that we often read in the newspapers but rarely understand. For instance, we read that Iran has been "sactioned" because it hasn't stopped its ambitions to enrich uranium which can be used to build a nuclear weapon. But what exactly are sanctions? How do they work? What kind of work goes on behind the scenes? How can a country be isolated from the global financial system? Why it can't be a one-size-fits-all? Eddie has worked at the US Treasury, the State Department and the Pentagon and played a key role in designing sanctions on Iran and Russia. In this podcast he talks about the evolution of economic warfare and how states can throttle economies without firing a shot. What work and what backfires? And what have policymakers learned so far?

Jason Burke has spent decades reporting from conflict zones around the world. In this episode he speaks about his latest book, "The Revolutionists: The Story of the Extremists Who Hijacked the 1970s". Jason explains how Palestinian factions turned aircraft hijacking into a coordinated political strategy, who the key figures were and how these operations were planned and carried out. He also describes the intelligence world that operated alongside this violence, what the day-to-day life of a spy looked like in the 1970s and how states quietly cooperated across borders. He also goes on to examine the wider consequences of this period, including Israel’s response and the international coordination that made operations such as the Entebbe rescue possible, an audacious raid possible as much by politics as by military planning.

Patrick McGee, the Financial Times San Francisco correspondent, covers Apple and the U.S. technology industry. His book, Apple in China: The Capture of the World's Greatest Company is a brilliant read. In this podcast he explains how Apple became deeply tied to China’s factories, workers and politics and why that relationship still defines the company today. He also discusses the roles of Steve Jobs, Jony Ive, Tim Cook and others in shaping Apple’s culture while revealing how design, operations and manufacturing came together to create some of the most influential products of our time.

Marc J. Dunkelman is a political scientist and author of Why Nothing Works: Who Killed Progress and How to Bring It Back. Drawing on examples from infrastructure, public policy and everyday bureaucracy, Marc explains why institutions that once delivered big projects now struggle to get even simple things done. He brings to fore the cultural shifts since the 1970s, America’s “vitocracy” and why good ideas get stuck between competing interests. It's a clear, grounded look at how systems break and what it would take to fix them and is as relevant for those living outside the US.

Danny Bate joins us to talk about the history of the English alphabet, letter by letter. From the ancient Egyptian origins of A to the comeback of K, Danny talks about how writing systems travelled across civilisations and shaped modern English. We discuss silent letters, spelling quirks, phonics, Scrabble and standup comedy. Drawing on his work as a linguist, Bate explains how sound, history, and habit come together in the way we read and write today. His latest book "Why Q Needs U" was shortlisted among the best books of 2025 by The Economist and is a brilliant read.

Few people have had more access to Jensen Huang, Nvidia’s charismatic founder, than Stephen Witt. In his book "The Thinking Machine: Jensen Huang, Nvidia, and the World’s Most Coveted Microchip", Witt traces the company’s three-decade journey under the leadership of a man he describes as sometimes “neurotic”, a founder who, despite being at the top of his game, constantly fears going out of business. And yet, his team remains fiercely loyal. He rarely fires those who face his ire. So how does he lead a company in an industry where every few years the technology is upended and replaced by something entirely new? And how does he stay grounded while working relentless hours? Stephen spoke to hundreds of people to find the answers, many of which he shares in his book and in this podcast.

Why do humans go to war? Is peace ever truly possible? In this podcast historian of the Second World War and expert on totalitarian regimes and military conflict joins us to talk about his latest book, "Why War?". Drawing on decades of research, Prof Overy talks about organized violence from prehistoric times to modern state conflicts. He explains how war has evolved and what drives it and how leaders can use provocative language to brainwash their people before invading another country. What we can learn from nations, including India, that have managed to avert a full-scale war despite decades of conflicts with their neighbouring countries? Despite all the grim violence around us in Gaza and Ukraine, Prof Overy remains hopeful and says that fears of a third world war may be overblown.

Charlie English is the author of "The CIA Book Club: The Best Kept Secret of the Cold War". In this episode he talks about a little-known chapter in Cold War history where the CIA smuggled banned books into the Eastern Bloc in an effort to challenge communist ideology. Charlie shares how the CIA ran this literary operation for over three decades, why even detective novels had political weight in Soviet-ruled countries, and what it meant to grow up under state censorship so tight you needed permission to buy a sheet of paper.

Ludwig Siegele, senior editor AI Initiatives at The Economist talks about how Chinese AI companies like DeepSeek and Alibaba are disrupting the status quo. They are building high-performing models at lower costs and releasing some of them as open source. How did they manage to pull this off and what does this mean for the global AI race? Ludwig joined The Economist as a US technology correspondent in 1998 and has covered the Silicon Valley since the Internet, as we know it, was born.

Carl Zimmer, acclaimed science writer and author of "Airborne: The Hidden History of the Life We Breathe", joins the show to explore the unseen world within the air around us. He talks about what most of us never think about: the air we breathe. He explains how scientists slowly uncovered the truth about airborne diseases, why it took decades for basic facts to gain acceptance, and what history, both recent and ancient, tells us about the hidden life in the atmosphere.

In this episode, legendary cricketer and former England captain, Mike Brearley talks about his rich childhood memories, early influences, the art of leadership and the life of a cricketer.

From dodging lava bombs at Stromboli to facing AK-47s in the Danakil Depression, Clive shares gripping stories from his fieldwork and the unexpected human side of volcanoes. We explore his acclaimed book, "Mountains of Fire: The Secret Lives of Volcanoes" and discover how volcanic eruptions can alter climate, tell us a lot about our planet's past. In his typical self-deprecating humour Clive instills an infectious sense of wonder, something he credits to his mother.

Investigative journalist Charles Piller unravels one of the biggest scientific scandals in recent history. Drawing from his book "Doctored: Fraud, Arrogance, and Tragedy in the Quest to Cure Alzheimer's", Charles reveals how falsified data propped up a dominant theory in Alzheimer’s research, diverting billions in funding and delaying real progress. With over 30 million people affected worldwide, Charles talks about the human toll of the disease, the scientific misconduct that shook the field and the faint but growing signs of hope.

John Dykes has worn many hats: from features writer to one of the world’s most sought-after sports presenters. In this podcast, he shares insights and anecdotes from his three-decade career, helping individuals and organisations to master storytelling, craft compelling pitches, create high-performance teams and manage crises in his new innings as a solopreneur. Reflecting on iconic moments, from covering cricket, football, tennis, Formula 1, MotoGP and golf to interviewing legends like Thierry Henry and Serena Williams, John emphasises the power of preparation over “winging it”. He also explores the value of embracing discomfort for long-term growth, a mindset he embodies at 60, while busting many myths about aging.

His latest book, The Forbidden Garden of Leningrad: A True Story of Science and Sacrifice in a City Under Siege, chronicles the heroic botanists who risked, and in some cases, gave their lives to safeguard a priceless seed collection during the longest blockade in recorded history. They chose starvation over consuming the very seeds that could prevent future famines. Simon shares the story of visionary scientist Nikolai Vavilov and his dedicated team, who preserved the world’s first seed bank under unimaginable conditions.
