Carl Zimmer is one of the finest science communicators of our time, having spent decades writing about biology, evolution, and heredity. His latest (and 16th) book, Air-Borne: The Hidden History of the Life We Breathe, explores something even more fundamental—how the very air around us is teeming with life, from pollen to pathogens to microbes floating miles above the Earth.

He joins Tyler to discuss why it took scientists so long to accept airborne disease transmission and more, including why 19th-century doctors thought hay fever was a neurosis, why it took so long for the WHO and CDC to acknowledge COVID-19 was airborne, whether ultraviolet lamps can save us from the next pandemic, how effective masking is, the best theory on the anthrax mailings, how the U.S. military stunted aerobiology, the chance of extraterrestrial life in our solar system, what Lee Cronin’s “assembly theory” could mean for defining life itself, the use of genetic information to inform decision-making, the strangeness of the Flynn effect, what Carl learned about politics from growing up as the son of a New Jersey congressman, and much more.

How much of your life’s trajectory was set in motion centuries ago? Gregory Clark has spent decades studying social mobility, and his findings suggest that where you land in society is far more predictable than we like to think. Using historical data, surname analysis, and migration patterns, Clark argues that social mobility rates have remained largely unchanged for 300 years—even across radically different political and economic systems.

He and Tyler discuss why we should care about relative mobility vs growing the size of the pie, how physical mobility does and doesn’t matter, why England was a meritocracy by 1700, how assortative mating affects economic and social progress, why India industrialized so late, a new potential explanation why Britain’s economic performance has been lukewarm since WWI, Malthusian societies then and now, whether a “hereditarian” stance favors large-scale redistribution or a free-market approach, the dynamics of assimilation within Europe and the role of negative selection in certain migrations, the challenge of accurately measuring living standards, the neighborhood-versus-family debate over what drives mobility, whether we need datasets larger than humanity itself to decode the genetics of social outcomes, and much more.

For Ross Douthat, phenomena like UFO sightings and the simulation hypothesis don't challenge religious belief—they demonstrate how difficult it is to escape religious questions entirely. His new book, Believe: Why Everyone Should Be Religious makes the case for religious faith in an age of apparent disenchantment.

In his third appearance on Conversations with Tyler, Ross joined Tyler to discuss what getting routed by Christopher Hitchens taught him about religious debate, why the simulation hypothesis resembles ancient Gnostic religion, what Mexican folk Catholicism reveals about spiritual intermediaries, his evolving views on papal authority in the Francis era, what UFO sightings might tell us about supernatural reality, why he's less apocalyptic than Peter Thiel about the Antichrist, and why he's publishing a fantasy novel on Substack before AI potentially transforms creative writing.

Joe Boyd was there when Dylan went electric, when Pink Floyd was born, and when Paul Simon brought Graceland to the world. But far from being just another music industry insider, Boyd has spent decades exploring how the world's musical traditions connect and transform each other. His new book And the Roots of Rhythm Remain, is seventeen years in the making, and is in Tyler’s words “the most substantive, complete, thorough, and well-informed book on world music ever written.” From producing Albanian folk recordings to discovering the hidden links between Mississippi Delta blues and Indian classical music, Boyd's journey reveals how musical innovation often emerges when traditions collide.

He joins Tyler to discuss why Zulu music became politically charged in South Africa, what makes Albanian choral music distinct from Bulgarian polyphony, what it was like producing Toots and the Maytals, his role in the famous "Dueling Banjos" scene in Deliverance, his work with Stanley Kubrick on A Clockwork Orange, his experiences with Syd Barrett and Pink Floyd, how he shaped R.E.M.'s sound on Fables of the Reconstruction, what really happened when Dylan went electric at Newport, how the Beatles integrated Indian music, what makes the Kinshasa guitar sound impossible to replicate, and how he maintains his collection of 6,000 vinyl LPs and 30,000 CDs, what he’ll do next, and more.

Scott Sumner didn't follow the typical path to economic influence. He nearly lost his teaching job before tenure, did his best research after most academics slow down, and found his largest audience through blogging in his 50s and 60s, in the wake of the 2008 financial crisis. Yet this unconventional journey led him to become one of the most influential monetary thinkers of the past two decades.

Scott joins Tyler to discuss what reading Depression-era newspapers revealed about Hitler's rise, when fiat currency became viable, why Sweden escaped the worst of the 1930s crash, whether bimetallism ever made sense, where he'd time-travel to witness economic history, what 1920s Hollywood movies get wrong about their era, how he developed his famous maxim "never reason from a price change," whether the Fed can ever truly follow policy rules like NGDP targeting, if Congress shapes monetary policy more than we think, the relationship between real and nominal shocks, his favorite Hitchcock movies, why Taiwan's 90s cinema was so special, how Ozu gets better with age, whether we'll ever see another Bach or Beethoven, how he ended up at the University of Chicago, what it means to be a late bloomer in academia, and more.

What can Thomas Hardy’s tortured marriages teach us about love, obsession, and second chances? In this episode, biographer, novelist, and therapist Paula Byrne examines the intimate connections between life and literature, revealing how Hardy’s relationships with women shaped his portrayals of love and tragedy. Byrne, celebrated for her bestselling biographies of Jane Austen, Evelyn Waugh, and Barbara Pym, brings her unique perspective to explore the profound ways personal relationships, cultural history, and creative ambition intersect to shape some of the most enduring works in literary history.

Tyler and Paula discuss Virginia Woolf’s surprising impressions of Hardy, why Wessex has lost a sense of its past, what Jude the Obscure reveals about Hardy’s ideas about marriage, why so many Hardy tragedies come in doubles, the best least-read Hardy novels, why Mary Robinson was the most interesting woman of her day, how Georgian theater shaped Jane Austen’s writing, British fastidiousness, Evelyn Waugh’s hidden warmth, Paula’s strange experience with poison pen letters, how American and British couples are different, the mental health crisis among teenagers, the most underrated Beatles songs, the weirdest thing about living in Arizona, and more.

In his landmark multi-volume biography of Stalin, Stephen Kotkin shows how totalitarian power worked not just through terror from above, but through millions of everyday decisions from below. Currently a senior fellow at the Hoover Institution after 33 years at Princeton, Kotkin brings both deep archival work and personal experience to his understanding of Soviet life, having lived in Magnitogorsk during the 1980s and seen firsthand how power operates in closed societies.

Tyler sat down with Stephen to discuss the state of Russian Buddhism today, how shamanism persists in modern Siberia, whether Siberia might ever break away from Russia, what happened to the science city Akademgorodok, why Soviet obsession with cybernetics wasn't just a mistake, what life was really like in 1980s Magnitogorsk, how modernist urban planning failed there, why Prokofiev returned to the USSR in 1936, what Stalin actually understood about artistic genius, how Stalin's Georgian background influenced him (or not), what Michel Foucault taught him about power, why he risked his tenure case to study Japanese, how his wife's work as a curator opened his eyes to Korean folk art, how he's progressing on the next Stalin volume, and much more.

Neal Stephenson’s ability to illuminate complex, future-focused ideas in ways that both provoke thought and spark wonder has established him as one of the most innovative thinkers in literature today. Yet his new novel, Polostan, revisits the Soviet era with a twist, shifting his focus from the speculative technologies of tomorrow to the historical currents of the 1930s.

In Neal's second appearance, Tyler asks him why he sometimes shifts from envisioning the future to illustrating the past, the rise of history autodidacts, the implications of leaked secrets from the atomic age to today’s AI, the logistics of faking one’s death, why he still drafts novels in longhand, Soviet idealism among Western intellectuals, which Soviet achievements he admires, the lag in AR development, how LLMs might boost AR, whether social media is increasingly giving way to private group chats, his continuing influence on technologists, why AI-generated art might struggle to connect with readers, the primer from The Diamond Age in light of today’s LLMs, the prospect of AGI becoming an unnoticed background tool, what Neal believes the world really needs more of, what lies ahead in Polostan and the broader “Bomb Light” series, and more
