Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasSolo: Fine-Tuning, God, and the MultiverseCertain features of our universe seem unnatural to us. These include "constants of nature" such as the cosmological constant and the mass of the Higgs boson, as well as features of the initial conditions like the curvature of space and the initial entropy. But they can't truly be "unnatural" -- they are literally features of Nature itself. Some have turned to the anthropic principle and the multiverse, while others look to theism for an explanation. I talk here about my views on the various attitudes one might take toward these apparent fine-tunings, and why it is important to think...
2025-10-061h 54Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasSolo: Does Time Exist?A new year, and a new centennial -- 300 (regularly-numbered) episodes of Mindscape! Our tradition is to have a solo episode, and what better topic than the nature of time? Physicists and philosophers have so frequently suggested that time is some kind of illusion that it's become almost passé to believe that it might be fundamental. This is an issue where, despite the form of the question, physics has important things to say that most philosophers haven't yet caught up to. I will talk about ideas from quantum mechanics and quantum gravity that bear on the question of whether time i...

But as usual, we wrap up with a Holiday Message. This year, inspired by Joni Mitchell's "Hits" and "Misses" albums, I go through my scientific papers and talk about some of my favorites -- some of which were hits, in terms of making an impact on subsequent research, and some of which were misses by that standard. But I love them all! It's an excuse to talk about process -- how papers come to be, from the initial informal idea to sitting down...

2024-06-1106 minSean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasRaphaël Millière on How Artificial Intelligence ThinksWelcome to another episode of Sean Carroll's Mindscape. Today, we're joined by Raphaël Millière, a philosopher and cognitive scientist at Columbia University. We'll be exploring the fascinating topic of how artificial intelligence thinks and processes information. As AI becomes increasingly prevalent in our daily lives, it's important to understand the mechanisms behind its decision-making processes. What are the algorithms and models that underpin AI, and how do they differ from human thought processes? How do machines learn from data, and what are the limitations of this learning? These are just some of the questions we'll be exploring in...

The residents of her cloistered Colorado hometown had scoured every inch of prairie. Jonelle’s face had been on milk cartons nationwide. Even the President of the United States had appealed to the public for help. Still, every lead had fizzled. Every person of interest had turned out to be a dead end. Then, in 2019, Jonelle’s remains were unearthed near the foothills of the Rocky Mountains. With the disc...

The prime suspect was her husband, famed actor Robert Blake. But Bonny, a longtime con artist, had plenty of enemies. She left behind a trail of men she’d scammed, and she had a volatile relationship with Christian Brando, the troubled son of movie star Marlon Brando. Not since the O.J. Simpson case had the eyes of the nation been so fixated on a homicide. The search for Bonny’s killer took detectives on an eleven-month odyssey across the c...

2022-06-062h 14Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasIntroducing: OperatorDuring the 1-900 number craze of the Nineties, one company provided the vast majority of phone sex. American Telnet was an empire founded by the man who called himself “The Telephone Pimp.” He ran the company “like General Motors” and got filthy rich doing it. But for the (mostly) women who answered the calls and delivered fantasies 24-7, it was a different story. The powerful stigma against sex work was always lurking just beneath the surface, until it threatened to tear apart the whole company. Hosted by Tina Horn (Why Are People Into That?), OPERATOR is an eight-part series about bi...

Carroll on Randomness and the Course of EvolutionEvolution is a messy business, involving as it does selection pressures, mutations, genetic drift, and the effects of random external interventions. So in the end, how much of it is predictable, and how much is in the hands of chance? Today we’re thrilled to have as a guest my evil (but more respectable, by most measures) twin, the biologist Sean B. Carroll. Sean is both a leader of the modern evo-devo revolution, and a wonderful and diverse writer. We talk about the importance of randomness and unpredictability in life, from the evolution of species to the daily routine of...
2020-10-051h 20Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasNeil Johnson on Complexity, Conflict, and InfodemiologyPhysicists have traditionally simplified systems as much as possible, in order to shed light on fundamental properties. But small, simple parts build up into large, complex wholes. Are there new rules and laws of nature that apply specifically to the realm of complexity? This has been a popular question for a few decades now, and we have some answers but not as many as we would like. Neil Johnson is an expert on complex systems generally, and information networks in particular. We discuss how self-organization can arise from individual units following their own agendas, and how we can mathematically...

2020-08-101h 18Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasCarl Bergstrom on Information, Disinformation, and BullshitWe are living, in case you haven’t noticed, in a world full of bullshit. It’s hard to say whether the amount is truly increasing, but it seems that everywhere you look someone is trying to convince you of something, regardless of whether that something is actually true. Where is this bullshit coming from, how is it disseminated, and what can we do about it? Carl Bergstrom studies information in the context of biology, which has led him to investigate the flow of information and disinformation in social networks, especially the use of data in misleading ways. In the...
2020-08-031h 24Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasRuss Shafer-Landau on the Reality of MoralityDespite occasional and important disagreements, most people are in rough agreement about what it means to be moral, to do the right thing. There’s much less agreement about why we should be moral, or even what kind of answer to that question could be convincing. Philosopher Russ Shafer-Landau is one of the leading proponents of moral realism — the view that objective moral truths exist independently of human choices. That’s not my own view, but ethics and meta-ethics are areas in which I think it’s wise to keep an open mind and listen to smart people who disagree. Th...
2020-07-271h 30Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasStuart Bartlett on What "Life" MeansSomeday, most likely, we will encounter life that is not as we know it. We might find it elsewhere in the universe, we might find it right here on Earth, or we might make it ourselves in a lab. Will we know it when we see it? “Life” isn’t a simple unified concept, but rather a collection of a number of life-like properties. I talk with astrobiologist Stuart Bartlett, who (in collaboration with Michael Wong) has proposed a new way of thinking about life based on four pillars: dissipation, autocatalysis, homeostasis, and learning. Their framework may or may not bec...
2020-07-201h 25Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasAnn-Sophie Barwich on the Science and Philosophy of SmellWe gather empirical evidence about the nature of the world through our senses, and use that evidence to construct an image of the world in our minds. But not all senses are created equal; in practice, we tend to privilege vision, with hearing perhaps a close second. Ann-Sophie Barwich wants to argue that we should take smell more seriously, and that doing so will give us new insights into how the brain works. As a working philosopher and neuroscientist, she shares a wealth of fascinating information about how smell works, how it shapes the way we think, and what...
2020-07-131h 17Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasDavid Rosen and Scott Miles on the Neuroscience of Music and CreativityCreativity is one of those things that we all admire but struggle to define or make concrete. Music provides a useful laboratory in which to examine what creativity is all about — how do people become creative, what is happening in their brains during the creative process, and what kinds of creativity does the audience actually enjoy? David Rosen and Scott Miles are both neuroscientists and musicians who have been investigating this question from the perspective of both listeners and performers. They have been performing neuroscientific experiments to understand how the brain becomes creative, and founded Secret Chord Laboratories to de...
2020-07-061h 26Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasJ. Kenji López-Alt on Cooking As and With ScienceCooking is art, but it’s also very much science — mostly chemistry, but with important contributions from physics and biology. (Almost like a well-balanced recipe…) And I can’t think of anyone better to talk to about the intersection of these fields than Kenji López-Alt: professional chef and restauranteur, MIT graduate, and author of The Food Lab. We discuss how modern scientific ideas can improve your cooking, and more importantly, how to bring a scientific approach to cooking anything at all. Then we also get into the cultural and personal resonance of food, and offer a few practical tips.
2020-06-291h 15Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasMaria Konnikova on Poker, Psychology, and ReasonThe best chess and Go players in the world aren’t human beings any more; they’re artificially-intelligent computer programs. But the best poker players are still humans. Poker is a laboratory for understanding how rationality works in real-world situations: it features stochastic events, incomplete information, Bayesian updating, game theory, reading other people, a battle between emotions and reason, and real-world stakes. Maria Konnikova started in psychology, turned to writing, and then took up professional-level poker, and has learned a lot along the way about the challenges of being rational. We talk about what games like poker can teach us a...
2020-06-221h 20Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasDavid Baltimore on the Mysteries of VirusesI recently saw an estimate that if you took all the novel coronaviruses in the world (the actual viruses, not patients), you could fit them into a bucket no more than a couple of liters in volume. A huge impact has been wrought by a very small amount of stuff. The world of viruses is vast and complicated, and we’re still learning some of its basic features. Today’s guest David Baltimore won the Nobel Prize in Physiology or Medicine for the discovery that genetic information in viruses could flow from RNA to DNA, establishing an exception to the...
2020-06-151h 14Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasSolo | Life and Its MeaningA podcast only hits the century mark once! And for Mindscape, this is it. There have been holiday messages and bonus episodes and the like. But this is the 100th officially-numbered episode. To celebrate, I decided to treat myself to a solo episode in which I reflect, somewhat non-systematically, on the age-old question of the meaning of life. I end up spending a lot (most?) of the time talking about the meaning of “life,” i.e. what it means to be a living organism in a naturalistic universe. But then I go on to muse about the construction of huma...
2020-06-081h 33Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasScott Aaronson on Complexity, Computation, and Quantum GravityThere are some problems for which it’s very hard to find the answer, but very easy to check the answer if someone gives it to you. At least, we think there are such problems; whether or not they really exist is the famous P vs NP problem, and actually proving it will win you a million dollars. This kind of question falls under the rubric of “computational complexity theory,” which formalizes how hard it is to computationally attack a well-posed problem. Scott Aaronson is one of the world’s leading thinkers in computational complexity, especially the wrinkles that enter once...
2020-06-011h 52Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasOlga Khazan on Living and Flourishing While Being WeirdEach of us is different, in some way or another, from every other person. But some are more different than others — and the rest of the world never stops letting them know. Societies set up “norms” that define what constitute acceptable standards of behavior, appearance, and even belief. But there will always be those who find themselves, intentionally or not, in violation of those norms — people who we might label “weird.” Olga Khazan was weird in one particular way, growing up in a Russian immigrant family in the middle of Texas. Now as an established writer, she has been exploring wh...
2020-05-251h 01Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasJohn Danaher on Our Coming Automated UtopiaHumans build machines, in part, to relieve themselves from the burden of work on difficult, repetitive tasks. And yet, despite the fact that machines are everywhere, most of us are still working pretty hard. But maybe that’s about to change. Futurists like John Danaher believe that society is finally on the brink of making a transition to a world in which work would be optional, rather than mandatory — and he thinks that’s a very good thing. It will take some adjusting, personally as well as economically, but he envisions a future in which human creativity and artistic impuls...
2020-05-181h 22Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasLina Necib on What and Where the Dark Matter IsThe past few centuries of scientific progress have displaced humanity from the center of it all: the Earth is not at the middle of the Solar System, the Sun is but one star in a large galaxy, there are trillions of galaxies, and so on. Now we know that we’re not even made of the same stuff as most of the universe; for every amount of ordinary atoms and other known particles, there is five times as much dark matter, some kind of stuff we haven’t identified in laboratory experiments. But we do know a great deal abou...
2020-05-111h 21Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasLiam Kofi Bright on Knowledge, Truth, and ScienceEverybody talks about the truth, but nobody does anything about it. And to be honest, how we talk about truth — what it is, and how to get there — can be a little sloppy at times. Philosophy to the rescue! I had a very ambitious conversation with Liam Kofi Bright, starting with what we mean by “truth” (correspondence, coherence, pragmatist, and deflationary approaches), and then getting into the nitty-gritty of how we actually discover it. There’s a lot to think about once we take a hard look at how science gets done, how discoveries are communicated, and what different kinds of p...
2020-05-041h 35Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasStuart Russell on Making Artificial Intelligence Compatible with HumansArtificial intelligence has made great strides of late, in areas as diverse as playing Go and recognizing pictures of dogs. We still seem to be a ways away from AI that is “intelligent” in the human sense, but it might not be too long before we have to start thinking seriously about the “motivations” and “purposes” of artificial agents. Stuart Russell is a longtime expert in AI, and he takes extremely seriously the worry that these motivations and purposes may be dramatically at odds with our own. In his book Human Compatible, Russell suggests that the secret is to give up on bu...
2020-04-271h 27Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasRae Wynn-Grant on Bears, Humans, and Other PredatorsHuman beings have a strange fascination with dangerous, predatory animals — bears, lions, wolves, sharks, and more. The top of the food chain is an interesting and precarious place to live; while you might be the boss of your local environment, you also depend on the functioning of an entire ecology. Rae Wynn-Grant is a carnivore ecologist who studies how large predators migrate, feed, reproduce — and especially how they interact with humans. We talk about the diverse social structures of different species of carnivores, how they find mates, and how they diversify their diet. And of course we discuss how huma...
2020-04-201h 02Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasKevin Hand on Life Elsewhere in the Solar SystemIt’s hard doing science when you only have one data point, especially when that data point is subject to an enormous selection bias. That’s the situation faced by people studying the nature and prevalence of life in the universe. The only biosphere we know about is our own, and our knowing anything at all is predicated on its existence, so it’s unclear how much it can teach us about the bigger picture. That’s why it’s so important to search for life elsewhere. Today’s guest is Kevin Hand, a planetary scientist and astrobiologist who knows as muc...
2020-04-131h 56Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasScott Barry Kaufman on the Psychology of TranscendenceIf one of the ambitious goals of philosophy is to determine the meaning of life, one of the ambitious goals of psychology is to tell us how to achieve it. An influential work in this direction was Abraham Maslow’s hierarchy of needs — a list of human needs, often displayed suggestively in the form of a pyramid, ranging from the most basic (food and shelter) to the most refined. At the top lurks “self-actualization," the ultimate goal of achieving one’s creative capacities. Psychologist Scott Barry Kaufman has elaborated on this model, both by exploring less-well-known writings of Maslow’s, and also...
2020-04-061h 19Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasDavid Kaiser on Science, Money, and PowerScience costs money. And for a brief, glorious period between the start of the Manhattan Project in 1939 and the cancellation of the Superconducting Super Collider in 1993, physics was awash in it, largely sustained by the Cold War. Things are now different, as physics — and science more broadly — has entered a funding crunch. David Kaiser, who is both a working physicist and an historian of science, talks with me about the fraught relationship between scientists and their funding sources throughout history, from Galileo and his patrons to the current rise of private foundations. It’s an interesting listen for anyone who wo...
2020-03-301h 34Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasLera Boroditsky on Language, Thought, Space, and TimeWhat direction does time point in? None, really, although some people might subconsciously put the past on the left and the future on the right, or the past behind themselves and the future in front, or many other possible orientations. What feels natural to you depends in large degree on the native language you speak, and how it talks about time. This is a clue to a more general phenomenon, how language shapes the way we think. Lera Boroditsky is one of the world’s experts on this phenomenon. She uses how different languages construe time and space (as we...
2020-03-231h 28Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasTara Smith on Coronavirus, Pandemics, and What We Can DoThis is a special episode of Mindscape, thrown together quickly. Many thanks to Tara Smith for joining me on short notice. Tara is an epidemiologist, and a great person to talk to about the novel coronavirus (and its associated disease, COVID-19) pandemic currently threatening the world. We talk about what viruses are, how they spread, and a lot of the science behind virology and pandemics. We also take a practical turn, talking about what measures (washing hands, social distancing, self-isolation) are useful at combating the spread of the virus, and which (wearing masks) are probably not. Then we look...
2020-03-181h 20Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasNeil Shubin on Evolution, Genes, and Dramatic Transitions“What good is half a wing?” That’s the rhetorical question often asked by people who have trouble accepting Darwin’s theory of evolution by natural selection. Of course it’s a very answerable question, but figuring out what exactly the answer is leads us to some fascinating biology. Neil Shubin should know: he is the co-discoverer of Tiktaalik Roseae, an ancient species of fish that was in the process of learning to walk and breathe on land. We talk about how these major transitions happen — typically when evolution finds a way to re-purpose existing organs into new roles — and how we can...
2020-03-161h 33Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasKarl Friston on Brains, Predictions, and Free EnergyIf you tell me that one of the world’s leading neuroscientists has developed a theory of how the brain works that also has implications for the origin and nature of life more broadly, and uses concepts of entropy and information in a central way — well, you know I’m going to be all over that. So it’s my great pleasure to present this conversation with Karl Friston, who has done exactly that. One of the most highly-cited neuroscientists now living, Friston has proposed that we understand the brain in terms of a free energy principle, according to which our...
2020-03-091h 29Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasMartin Rees on Threats to Humanity, Prospects for Posthumanity, and Life in the UniverseAnyone who has read histories of the Cold War, including the Cuban Missile Crisis and the 1983 nuclear false alarm, must be struck by how incredibly close humanity has come to wreaking incredible destruction on itself. Nuclear war was the first technology humans created that was truly capable of causing such harm, but the list of potential threats is growing, from artificial pandemics to runaway super-powerful artificial intelligence. In response, today’s guest Martin Rees and others founded the Cambridge Centre for the Study of Existential Risk. We talk about what the major risks are, and how we can best reason...
2020-03-021h 40Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasL.A. Paul on Transformative Experiences and Your Future SelvesIt’s hard to make decisions that will change your life. It’s even harder to make a decision if you know that the outcome could change who you are. Our preferences are determined by who we are, and they might be quite different after a decision is made — and there’s no rational way of taking that into account. Philosopher L.A. Paul has been investigating these transformative experiences — from getting married, to having a child, to going to graduate school — with an eye to deciding how to live in the face of such choices. Of course we can ask peopl...
2020-02-241h 14Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasSuresh Naidu on Capitalism, Monopsony, and InequalityNations generally want their economies to be rich, robust, and growing. But it’s also important to person to ensure that wealth doesn’t flow only to a few people, but rather that as many people as possible can enjoy the benefits of a healthy economy. As is well known, the best way to balance these interests is a contentious subject.

Not everyone agrees, however; in the words of former British Prime Minister Theresa May, “If you are a citizen of the world, you are a citizen of nowhere.” On the other side of the political spectrum, groups who share a feature of identity — race, ethnicity, gender, sexuality, and others — find it useful to band together to make political progress. Kwame Anthony Appiah is a leading philosopher and cultural...
2020-02-101h 38Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasRobin Carhart-Harris on Psychedelics and the BrainThe Convention on Psychotropic Substances was a 1971 United Nations treaty that placed strong restrictions on the use of psychedelic drugs — not only on personal use, but medical and scientific research as well. Along with restrictions placed by individual nations, it has been very difficult for scientists to study the effects of psychedelics on the brain, despite indications that they might have significant therapeutic potential. But this has gradually been changing, and researchers like Robin Carhart-Harris have begun to perform controlled experiments to see how psychedelics affect the brain, and what positive uses they might have. Robin and I talk abou...
2020-02-031h 17Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasEzra Klein on Politics, Polarization, and IdentityPeople have always disagreed about politics, passionately and sometimes even violently. But in certain historical moments these disagreements were distributed without strong correlations, so that any one political party would contain a variety of views. In a representative democracy, that kind of distribution makes it easier to accomplish things. In contrast, today we see strong political polarization: members of any one party tend to line up with each other on a range of issues, and correspondingly view the other party with deep distrust. Political commentator Ezra Klein has seen this shift in action, and has studied it carefully in...
2020-01-271h 21Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasJenann Ismael on Connecting Physics to the World of ExperiencePhysics is simple; people are complicated. But even people are ultimately physical systems, made of particles and forces that follow the rules of the Core Theory. How do we bridge the gap from one kind of description to another, explaining how someone we know and care about can also be “just” a set of quantum fields obeying impersonal laws? This is a hard question that comes up in a variety of forms — What is the “self”? Do we have free will, the ability to make choices? What are the moral and ethical ramifications of these considerations? Jenann Ismael is a philosophe...
2020-01-201h 26Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasSara Imari Walker on Information and the Origin of LifeWe are all alive, but “life” is something we struggle to understand. How do we distinguish a “living organism” from an emergent dynamical system like a hurricane, or a resource-consuming chemical reaction like a forest fire, or an information-processing system like a laptop computer? There is probably no one crisp set of criteria that delineates life from non-life, but it’s worth the exercise to think about what we really mean, especially as the quest to find life outside the confines of the Earth picks up steam. Sara Imari Walker planned to become a cosmologist before shifting her focus to astrobi...
2020-01-131h 23Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasDaniel Dennett on Minds, Patterns, and the Scientific ImageWilfrid Sellars described the task of philosophy as explaining how things, in the broadest sense of term, hang together, in the broadest sense of the term. (Substitute “exploring” for “explaining” and you’d have a good mission statement for the Mindscape podcast.) Few modern thinkers have pursued this goal more energetically, creatively, and entertainingly than Daniel Dennett. One of the most respected philosophers of our time, Dennett’s work has ranged over topics such as consciousness, artificial intelligence, metaphysics, free will, evolutionary biology, epistemology, and naturalism, always with an eye on our best scientific understanding of the phenomenon in question. Hi...

No substantive content or deep ideas, just me talking a bit about the state of the podcast and what’s on my mind. Since the big event for me in 2019 was the publication of Something Deeply Hidden, I thought it would be fun to talk about the process of writing and selling a popular book. Might be of interest to some of you out there!Mindscape takes off for the holidays, so the next regular episode will be published on Monday January 6. It’s a good one — maybe my favorit...
2019-12-221h 06Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasAzra Raza on The Way We Should Fight CancerIn the United States, more than one in five deaths is caused by cancer. The medical community has put enormous resources into fighting this disease, yet its causes and best treatments continue to be a puzzle. Azra Raza has been on both sides of the patient’s bed, as she puts it — both as an oncologist and expert in the treatment of Myelodisplastic Syndrome (MDS), and as a wife who lost her husband to cancer. In her new book, The First Cell, she argues that we have placed too much emphasis on treating cancer once it has already developed, and no...
2019-12-161h 22Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasNed Hall on Possible Worlds and the Laws of NatureIt’s too easy to take laws of nature for granted. Sure, gravity is pulling us toward Earth today; but how do we know it won’t be pushing us away tomorrow? We extrapolate from past experience to future expectation, but what allows us to do that? “Humeans” (after David Hume, not a misspelling of “human”) think that what exists is just what actually happens in the universe, and the laws are simply convenient summaries of what happens. “Anti-Humeans” think that the laws have an existence of their own, bringing what happens next into existence. The debate has implications for the notion o...
2019-12-091h 25Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasMax Tegmark on Reality, Simulation, and the MultiverseWe've talked a lot recently about the Many Worlds of quantum mechanics. That’s one kind of multiverse that physicists often contemplate. There is also the cosmological multiverse, which we talked about with Brian Greene. Today’s guest, Max Tegmark, has thought a great deal about both of those ideas, as well as a more ambitious and speculative one: the Mathematical Multiverse, in which we imagine that every mathematical structure is real, and the universe we perceive is just one such mathematical structure. And there’s yet another possibility, that what we experience as “reality” is just a simulation inside com...
2019-12-021h 11Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasStephen Greenblatt on Stories, History, and Cultural PoeticsAn infinite number of things happen; we bring structure and meaning to the world by making art and telling stories about it. Every work of literature created by human beings comes out of an historical and cultural context, and drawing connections between art and its context can be illuminating for both. Today’s guest, Stephen Greenblatt, is one of the world’s most celebrated literary scholars, famous for helping to establish the New Historicism school of criticism, which he also refers to as “cultural poetics.” We talk about how art becomes entangled with the politics of its day, and how we c...
2019-11-251h 06Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasGrimes (c) on Music, Creativity, and Digital PersonaeChanging technologies have always affected how we produce and enjoy art, and music might be the most obvious example. Radio and recordings made it easy for professional music to be widely disseminated, but created a barrier to its creation. Nowadays computers are helping to reverse that trend, allowing casual users to create slick songs of their own. Not everyone is equally good at it, however; Grimes (who currently goes by c, the symbol for the speed of light) is a wildly successful electronic artist who writes, produces, performs, and sings her own songs. We dig into how music is...
2019-11-181h 18Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasCésar Hidalgo on Information in Societies, Economies, and the UniverseMaxwell's Demon is a famous thought experiment in which a mischievous imp uses knowledge of the velocities of gas molecules in a box to decrease the entropy of the gas, which could then be used to do useful work such as pushing a piston. This is a classic example of converting information (what the gas molecules are doing) into work. But of course that kind of phenomenon is much more widespread -- it happens any time a company or organization hires someone in order to take advantage of their know-how. César Hidalgo has become an expert in this r...
2019-11-111h 16Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasPhilip Goff on Consciousness EverywhereThe human brain contains roughly 85 billion neurons, wired together in an extraordinarily complex network of interconnected parts. It’s hardly surprising that we don’t understand the mind and how it works. But do we know enough about our experience of consciousness to suggest that consciousness cannot arise from nothing more than the physical interactions of bits of matter? Panpsychism is the idea that consciousness, or at least some mental aspect, is pervasive in the world, in atoms and rocks as well as in living creatures. Philosopher Philip Goff is one of the foremost modern advocates of this idea. We h...
2019-11-041h 34Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasKatie Mack on How the Universe Will EndCosmologists are always talking excitedly about the Big Bang and all the cool stuff that happened in the 14 billion years between then and now. But what about the future? We don't know for sure, but we know enough about the laws of physics to sketch out several plausible scenarios for what the future of our universe will hold. Katie Mack is a cosmologist who is writing a book about the end of the universe. We talk about the possibilities of a Big Crunch (and potential Big Bounce), a gentle cooling off where the universe gradually grows silent, and of...
2019-10-281h 23Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasCory Doctorow on Technology, Monopoly, and the Future of the InternetLike so many technological innovations, the internet is something that burst on the scene and pervaded human life well before we had time to sit down and think through how something like that should work and how it should be organized. In multiple ways — as a blogger, activist, fiction writer, and more — Cory Doctorow has been thinking about how the internet is affecting our lives since the very beginning. He has been especially interested in legal issues surrounding copyright, publishing, and free speech, and recently his attention has turned to broader economic concerns. We talk about how the internet has...
2019-10-211h 17Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasMelanie Mitchell on Artificial Intelligence and the Challenge of Common SenseArtificial intelligence is better than humans at playing chess or go, but still has trouble holding a conversation or driving a car. A simple way to think about the discrepancy is through the lens of “common sense” — there are features of the world, from the fact that tables are solid to the prediction that a tree won’t walk across the street, that humans take for granted but that machines have difficulty learning. Melanie Mitchell is a computer scientist and complexity researcher who has written a new book about the prospects of modern AI. We talk about deep learning and othe...
2019-10-141h 22Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasKate Jeffery on Entropy, Complexity, and EvolutionOur observable universe started out in a highly non-generic state, one of very low entropy, and disorderliness has been growing ever since. How, then, can we account for the appearance of complex systems such as organisms and biospheres? The answer is that very low-entropy states typically appear simple, and high-entropy states also appear simple, and complexity can emerge along the road in between. Today’s podcast is more of a discussion than an interview, in which behavioral neuroscientist Kate Jeffery and I discuss how complexity emerges through cosmological and biological evolution. As someone on the biological side of things, Ka...
2019-10-071h 12Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasWill Wilkinson on Partisan Polarization and the Urban/Rural DivideThe idea of “red states” and “blue states” burst on the scene during the 2000 U.S. Presidential elections, and has a been a staple of political commentary ever since. But it’s become increasingly clear, and increasingly the case, that the real division isn’t between different sets of states, but between densely- and sparsely-populated areas. Cities are blue (liberal), suburbs and the countryside are red (conservative). Why did that happen? How does it depend on demographics, economics, and the personality types of individuals? I talk with policy analyst Will Wilkinson about where this division came from, and what it means for...
2019-09-301h 52Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasMichael Mann on Why Our Climate Is Changing and How We KnowWe had our fun last week, exploring how progress in renewable energy and electric vehicles may help us combat encroaching climate change. This week we’re being a bit more hard-nosed, taking a look at what’s currently happening to our climate. Michael Mann is one of the world’s leading climate scientists, and also a dedicated advocate for improved public understanding of the issues. It was his research with Raymond Bradley and Malcolm Hughes that introduced the “hockey stick” graph, showing how global temperatures have increased rapidly compared to historical averages. We dig a bit into the physics behind the...
2019-09-231h 17Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasRamez Naam on Renewable Energy and an Optimistic FutureThe Earth is heating up, and it’s our fault. But human beings are not always complete idiots (occasional contrary evidence notwithstanding), and sometimes we can even be downright clever. Dare we imagine that we can bring our self-inflicted climate catastrophe under control, through a combination of technological advances and political willpower? Ramez Naam is optimistic, at least about the technological advances. He is a technologist, entrepreneur, and science-fiction author, who has been following advances in renewable energy. We talk about the present state of solar, wind, and other renewable energy sources, and what our current rate of progress bo...
2019-09-161h 16Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasSolo -- Finding Gravity Within Quantum MechanicsI suspect most loyal Mindscape listeners have been exposed to the fact that I’ve written a new book, Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime. As I release this episode on Monday 9 September 2019, the book will officially be released tomorrow, in print, e-book, and audio versions. To get in the mood, we’ve had several podcast episodes on quantum mechanics, but the “emergence of spacetime” aspect has been neglected. So today we have a solo podcast in which I explain a bit about the challenges of quantum gravity, how Many-Worlds provides the best framework for thinking ab...
2019-09-091h 50Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasMichele Gelfand on Tight and Loose Societies and PeoplePhysicists study systems that are sufficiently simple that it’s possible to find deep unifying principles applicable to all situations. In psychology or sociology that’s a lot harder. But as I say at the end of this episode, Mindscape is a safe space for grand theories of everything. Psychologist Michele Gelfand claims that there’s a single dimension that captures a lot about how cultures differ: a spectrum between “tight” and “loose,” referring to the extent to which social norms are automatically respected. Oregon is loose; Alabama is tight. Italy is loose; Singapore is tight. It’s a provocative thes...
2019-09-021h 12Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasQuassim Cassam on Intellectual Vices and What to Do About ThemAll of us have been wrong about things from time to time. But sometimes it was a simple, forgivable mistake, while other times we really should have been correct. Properties that systematically prevent us from being correct, and for which we can legitimately be blamed, are “intellectual vices.” Examples might include closed-mindedness, wishful thinking, overconfidence, selective attention, and so on. Quassim Cassam is a philosopher who studies knowledge in various forms, and who has recently written a book Vices of the Mind: From the Intellectual to the Political. We talk about the nature of intellectual vices, how they manifest in pe...
2019-08-261h 10Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasLynne Kelly on Memory Palaces, Ancient and ModernMemory takes different forms. Memories can be encoded in the strength of neural connections in our brains, but there’s a sense in which photographs and written records are memories as well. What did people do before such forms of memory even existed? Lynne Kelly is a science writer and researcher who specializes in forms of memory in the ancient world, as well as a competitive memory expert in her own right. She has theorized that ancient structures such as Stonehenge might have served as memory palaces, encoding social knowledge over extended periods of time. We talk about how to...
2019-08-191h 15Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasAdam Becker on the Curious History of Quantum MechanicsThere are many mysteries surrounding quantum mechanics. To me, the biggest mysteries are why physicists haven’t yet agreed on a complete understanding of the theory, and even more why they mostly seem content not to try. This puzzling attitude has historical roots that go back to the Bohr-Einstein debates. Adam Becker, in his book What Is Real?, looks at this history, and discusses how physicists have shied away from the foundations of quantum mechanics in the subsequent years. We discuss why this has been the case, and talk about some of the stubborn iconoclasts who insisted on thinking abo...
2019-08-121h 40Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasSeth MacFarlane on Using Science Fiction to Explore HumanityFiction shines a light on the human condition by putting people into imaginary situations and envisioning what might happen. Science fiction expands this technique by considering situations in the future, with advanced technology, or with utterly different social contexts. Seth MacFarlane’s show The Orville is good old-fashioned space opera, but it’s also a laboratory for exploring the intricacies of human behavior. There are interpersonal conflicts, sexual politics, alien perspectives, and grappling with the implications of technology. I talk with Seth about all these issues, and maybe a little bit about whether it’s a good idea to block peop...
2019-08-051h 12Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasAstra Taylor on the Promise and Challenge of Democracy“Democracy may not exist, but we’ll miss it when it’s gone” — or so suggests the title of Astra Taylor’s new book. We all know how democracy falls short, in practice, of its lofty ideals; but we can also appreciate how democratic values are crucial in the fight for a more just society. In this conversation, we dig into the nature of democracy, from its origins to the present day. We talk about who gets to participate, how economic inequality affects political inequality, and how democratic ideals manifest themselves in any number of real-world situations.Support Mind...
2019-07-291h 23Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasKate Adamala on Creating Synthetic LifeScientists can’t quite agree on how to define “life,” but that hasn’t stopped them from studying it, looking for it elsewhere, or even trying to create it. Kate Adamala is one of a number of scientists engaged in the ambitious project of trying to create living cells, or something approximating them, starting from entirely non-living ingredients. Impressive progress has already been made. Designing cells from scratch will have obvious uses is biology and medicine, but also allow us to build biological robots and computers, as well as helping us understand how life could have arisen in the first pl...
2019-07-221h 12Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasA Conversation with Rob Reid on Quantum Mechanics and Many WorldsAs you may have heard, I have a new book coming out in September, Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime. To celebrate, we're going to have more than the usual number of podcasts about quantum mechanics over the next couple of months. Today is an experimental flipped podcast, in which I'm being interviewed by Rob Reid. Rob is the host of the After On podcast, of which this is also an episode. We talk about quantum mechanics generally and my favorite Many-Worlds approach in particular, homing in on the motivation for believing in all those...

But music affects your brain in certain specific ways, from changing our mood to helping us learn. As both a neuroscientist and an opera singer, Indre Viskontas is the ideal person to talk about the relationship between music and the brain. Her new book, How Music Can Make You Better, digs into why we love music, how it can unite and divide us, and how music has a special impact on the very young and the very old.

2019-07-081h 15Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasSolo -- On Morality and RationalityWhat does it mean to be a good person? To act ethically and morally in the world? In the old days we might appeal to the instructions we get from God, but a modern naturalist has to look elsewhere. Today I do a rare solo podcast, where I talk both about my personal views on morality, a variety of “constructivism” according to which human beings construct their ethical stances starting from basic impulses, logical reasoning, and communicating with others. In light of this view, I consider two real-world examples of contemporary moral controversies: Is it morally permissible to eat meat? Or i...
2019-07-012h 05Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasFrank Lantz on the Logic and Emotion of GamesGames play an important, and arguably increasing, role in human life. We play games on our computers and our phones, watch other people compete in games, and occasionally break out the cards or the Monopoly set. What is the origin of this human impulse, and what makes for a great game? Frank Lantz is both a working game designer and an academic who thinks about the nature of games and gaming. We discuss what games are, contrast the challenges of Go and Poker and other games, and investigate both the “dark energy” that games can sometimes induce and the ways they...
2019-06-241h 04Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasAnthony Aguirre on Cosmology, Zen, Entropy, and InformationCosmologists have a standard set of puzzles they think about: the nature of dark matter and dark energy, whether there was a period of inflation, the evolution of structure, and so on. But there are also even deeper questions, having to do with why there is a universe at all, and why the early universe had low entropy, that most working cosmologists don’t address. Today’s guest, Anthony Aguirre, is an exception. We talk about these deep issues, and how tackling them might lead to a very different way of thinking about our universe. At the end there’s an ent...
2019-06-171h 31Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasPatricia Churchland on Conscience, Morality, and the BrainIt’s fun to spend time thinking about how other people should behave, but fortunately we also have an inner voice that keeps offering opinions about how we should behave ourselves: our conscience. Where did that come from? Today’s guest, Patricia Churchland, is a philosopher and neuroscientist, one of the founders of the subfield of “neurophilosophy.” We dig into the neuroscience of it all, especially how neurochemicals like oxytocin affect our attitudes and behaviors. But we also explore the philosophical ramifications of having a conscience, with an eye to understanding morality and ethics in a neurophilosophical context. Support Mindscape on Patreon ...
2019-06-101h 12Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasNicholas Christakis on Humanity, Biology, and What Makes Us GoodIt’s easy to be cynical about humanity’s present state and future prospects. But we have made it this far, and in some ways we’re doing better than we used to be. Today’s guest, Nicholas Christakis, is an interdisciplinary researcher who studies human nature from a variety of perspectives, including biological, historical, and philosophical. His most recent book is Blueprint: The Evolutionary Origins of a Good Society, in which he tries to pinpoint the common features of all human societies, something he dubs the “social suite.” Marshaling evidence from genetics to network theory to accounts of shipwreck survivors, he...
2019-06-031h 54Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasMarq de Villiers on Hell and DamnationIf you’re bad, we are taught, you go to Hell. Who in the world came up with that idea? Some will answer God, but for the purpose of today’s podcast discussion we’ll put that possibility aside and look into the human origins and history of the idea of Hell. Marq de Villiers is a writer and journalist who has authored a series of non-fiction books, many on science and the environment. In Hell & Damnation, he takes a detour to examine the manifold ways in which societies have imagined the afterlife. The idea of eternal punishment is widespread, but not...
2019-05-271h 11Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasAdam Rutherford on Humans, Animals, and Life in GeneralMost people in the modern world — and the vast majority of Mindscape listeners, I would imagine — agree that humans are part of the animal kingdom, and that all living animals evolved from a common ancestor. Nevertheless, there are ways in which we are unique; humans are the only animals that stress out over Game of Thrones (as far as I know). I talk with geneticist and science writer Adam Rutherford about what makes us human, and how we got that way, both biologically and culturally. One big takeaway lesson is that it’s harder to find firm distinctions than you might...
2019-05-201h 38Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasKate Darling on Our Connections with RobotsMost of us have no trouble telling the difference between a robot and a living, feeling organism. Nevertheless, our brains often treat robots as if they were alive. We give them names, imagine that they have emotions and inner mental states, get mad at them when they do the wrong thing or feel bad for them when they seem to be in distress. Kate Darling is a research at the MIT Media Lab who specializes in social robotics, the interactions between humans and machines. We talk about why we cannot help but anthropomorphize even very non-human-appearing robots, and what that...
2019-05-131h 06Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasLeonard Susskind on Quantum Information, Quantum Gravity, and HolographyFor decades now physicists have been struggling to reconcile two great ideas from a century ago: general relativity and quantum mechanics. We don’t yet know the final answer, but the journey has taken us to some amazing places. A leader in this quest has been Leonard Susskind, who has helped illuminate some of the most mind-blowing ideas in quantum gravity: the holographic principle, the string theory landscape, black-hole complementarity, and others. He has also become celebrated as a writer, speaker, and expositor of mind-blowing ideas. We talk about black holes, quantum mechanics, and the most exciting new directions in qu...
2019-05-061h 13Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasAntonio Damasio on Feelings, Thoughts, and the Evolution of Humanity When we talk about the mind, we are constantly talking about consciousness and cognition. Antonio Damasio wants us to talk about our feelings. But it’s not in an effort to be more touchy-feely; Damasio, one of the world’s leading neuroscientists, believes that feelings generated by the body are a crucial part of how we achieve and maintain homeostasis, which in turn is a key driver in understanding who we are. His most recent book, The Strange Order of Things: Life, Feeling, and the Making of Cultures, is an ambitious attempt to trace the role of feelings and our biolo...
2019-04-291h 12Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasMatthew Luczy on the Pleasures of WineSome people never drink wine; for others, it’s an indispensable part of an enjoyable meal. Whatever your personal feelings might be, wine seems to exhibit a degree of complexity and nuance that can be intimidating to the non-expert. Where does that complexity come from, and how can we best approach wine? To answer these questions, we talk to Matthew Luczy, sommelier and wine director at Mélisse, one of the top fine-dining restaurants in the Los Angeles area. Matthew insisted that we actually drink wine rather than just talking about it, so drink we do. Therefore, in a Mindscape fir...

But recent years have seen the beginning of a boom in the number of objects orbiting Earth, as satellite tracking and communications have assumed enormous importance in the modern world. This raises obvious concerns for the control and eventual fate of these orbiting artifacts. Natalya Bailey is pioneering a novel approach to satellite propulsion, building tiny ion engines at her company Accion Systems. We talk about how satellite technology is rapidly changing, and what that means for the future of space travel inside and outside the Solar...
2019-04-1559 minSean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasSteven Strogatz on Synchronization, Networks, and the Emergence of Complex BehaviorOne of the most important insights in the history of science is the fact that complex behavior can arise from the undirected movements of small, simple systems. Despite the fact that we know this, we’re still working to truly understand it — to uncover the mechanisms by which, and conditions under which, complexity can emerge from simplicity. (Coincidentally, a new feature in Quanta on this precise topic came out while this episode was being edited.) Steven Strogatz is a leading researcher in this field, a pioneer both in the subject of synchronization and in that of small-world networks. He’s also a...
2019-04-081h 14Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasAdrienne Mayor on Gods and Robots in Ancient MythologyThe modern world is full of technology, and also with anxiety about technology. We worry about robot uprisings and artificial intelligence taking over, and we contemplate what it would mean for a computer to be conscious or truly human. It should probably come as no surprise that these ideas aren’t new to modern society — they go way back, at least to the stories and mythologies of ancient Greece. Today’s guest, Adrienne Mayor, is a folklorist and historian of science, whose recent work has been on robots and artificial humans in ancient mythology. From the bronze warrior Talos to the ev...
2019-04-011h 03Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasMalcolm MacIver on Sensing, Consciousness, and ImaginationConsciousness has many aspects, from experience to wakefulness to self-awareness. One aspect is imagination: our minds can conjure up multiple hypothetical futures to help us decide which choices we should make. Where did that ability come from? Today’s guest, Malcolm MacIver, pinpoints an important transition in the evolution of consciousness to when fish first climbed on to land, and could suddenly see much farther, which in turn made it advantageous to plan further in advance. If this idea is true, it might help us understand some of the abilities and limitations of our cognitive capacities, with potentially important ramifications fo...
2019-03-251h 19Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasAlan Lightman on Transcendence, Science, and a Naturalist’s Sense of MeaningLet’s say, for sake of argument, that you don’t believe in God or the supernatural. Is there still a place for talking about transcendence, the sacred, and meaning in life? Some of the above, but not all? Today’s guest, Alan Lightman, brings a unique perspective to these questions, as someone who has worked within both the sciences and the humanities at the highest level. In his most recent book, Searching for Stars on an Island in Maine, he makes the case that naturalists should take transcendence seriously. We talk about the assumptions underlying scientific practice, and the implic...
2019-03-181h 16Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasEdward Watts on the End of the Roman Republic and Lessons for DemocracyWhen many of us think “Ancient Rome,” we think of the Empire and the Caesars. But the Empire was preceded by the Roman Republic, which flourished for a full five centuries. Why, after such a long and prosperous run, would an essentially democratic form of government change — with a good deal of approval from its citizens — into an autocracy? That’s the question I discuss with today’s guest, historian Edward Watts. It’s a fascinating story with many contemporary resonances, especially how reformers choose to balance working within the system to overthrowing it entirely. Lessons for modern politics are left largely f...
2019-03-111h 31Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasDavid Albert on Quantum Measurement and the Problems with Many-WorldsQuantum mechanics is our best theory of how reality works at a fundamental level, yet physicists still can’t agree on what the theory actually says. At the heart of the puzzle is the “measurement problem”: what actually happens when we observe a quantum system, and why do we apparently need separate rules when it happens? David Albert is one of the leading figures in the foundations of quantum mechanics today, and we discuss the measurement problem and why it’s so puzzling. Then we dive into the Many-Worlds version of quantum mechanics, which is my favorite (as I explain in my fo...
2019-03-041h 42Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasJessica Yellin on The Changing Ways We Get Our NewsEverything we think about the world outside our immediate senses is shaped by information brought to us by other sources. In the case of what’s currently happening to the human race, we call that information “the news.” There is no such thing as “unfiltered” news — no matter how we get it, someone is deciding what information to convey and how to convey it. And the way that is happening is currently in a state of flux. Today’s guest, journalist Jessica Yellin, has seen the news business from the perspective of both the establishment and the upstart. Working for major news org...
2019-02-251h 08Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasPaul Bloom on Empathy, Rationality, Morality, and CrueltyWithin every person’s mind there is on ongoing battle between reason and emotion. It’s not always a battle, of course; very often the two can work together. But at other times, our emotions push us toward actions that our reason would counsel against. Paul Bloom is a well-known psychologist and author who wrote the provocatively-titled book Against Empathy: The Case for Rational Compassion, and is currently writing a book about the nature of cruelty. While I sympathize with parts of his anti-empathy stance, I try to stick up for the importance of empathy in the right circumstances. We have...
2019-02-181h 10Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasJames Ladyman on Reality, Metaphysics, and ComplexityReality is a tricky thing. Is love real? What about the number 5? This is clearly a job for a philosopher, and James Ladyman is one of the world’s acknowledged experts. He and his collaborators have been championing a view known as “structural realism,” in which real things are those that reflect true, useful patterns in the underlying reality. We talk about that, but also about a couple of other subjects in the broad area of philosophy of science: the history and current status of materialism/physicalism, and the nature of complex systems. This is a deep one. Support Mindscape on Patreon or Pa...
2019-02-111h 07Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasNaomi Oreskes on Climate Change and the Distortion of Scientific FactsOur climate is in the midst of dramatic changes, driven largely by human activity, with potentially enormous consequences for humanity and other species. That’s why science tells us, anyway. But there is an influential contingent, especially in the United States, who deny that reality, and work hard to prevent policy action that might ameliorate it. Where did this resistance come from, and what makes it so successful? Naomi Oreskes is a distinguished historian of science who has become, half-reluctantly, the world’s expert on this question. It turns out to be a fascinating story starting with just a handful of s...
2019-02-041h 10Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasWelcome to the Mindscape Podcast!I've decided to officially take the plunge into the world of podcasting. The new show will be called Mindscape, and will mostly consist of me talking to smart people about interesting ideas. (Occasionally it will be me talking by myself about ideas of questionable merit.) I'm a grizzled veteran at appearing on other podcasts, and it's past time I sat in the director's chair here.
