“Time” and “the brain” are two of those things that are somewhat mysterious, but it would be hard for us to live without. So just imagine how much fun it is to bring them together. Dean Buonomano is one of the leading neuroscientists studying how our brains perceive time, which is part of the bigger issue of how we construct models of the physical world around us. We talk about how the brain tells time very differently than the clocks that we’re used to, using different neuronal mechanisms for different timescales. This brings us to a very interesting conversation about the nature of time itself — Dean is a presentist, who believes that only the current moment qualifies as “real,” but we don’t hold that against him.Support Mindscape on Patreon.Dean Buonomano received his Ph.D. from the Department of Neurobiology and Anatomy at the University of Texas Medical School, Houston.

Imagine two people with exactly the same innate abilities, but one is born into a wealthy family and the other is born into poverty. Or two people born into similar circumstances, but one is paralyzed in a freak accident in childhood while the other grows up in perfect health. Is this fair? We live in a society that values some kind of “equality” — “All men are created equal” — without ever quite specifying what we mean. Elizabeth Anderson is a leading philosopher of equality, and we talk about what really matters about this notion. This leads to down-to-earth issues about employment and the work ethic, and how it all ties into modern capitalism. We end up agreeing that a leisure society would be great, but at the moment there’s plenty of work to be done.Support Mindscape on Patreon.Elizabeth Anderson received a Ph.D. in philosophy from Harvard University.

You might think that human beings, exhausted by competing for resources and rewards in the real world, would take it easy and stick to cooperation in their spare time. But no; we are fascinated by competition, and invent games and sports to create artificial competition just for fun. These competitions turn out to be wonderful laboratories for exploring concepts like optimization, resource allocation, strategy, and human psychology. Today’s guest, Daryl Morey, is a world leader in thinking analytically about sports, as well as the relationship between impersonal data and the vagaries of human behavior. He’s currently an executive in charge of the Philadelphia 76ers, but I promise you don’t need to be a fan of the Sixers or of basketball or of sports in general to enjoy this wide-ranging conversation.Support Mindscape on Patreon.Daryl Morey received a bachelor’s in computer science from Northwestern University, and an MBA from the MIT Sloan School of Management.

On a spectrum of philosophical topics, one might be tempted to put mathematics and morality on opposite ends. Math is one of the most pristine and rigorously-developed areas of human thought, while morality is notoriously contentious and resistant to consensus. But the more you dig into the depths, the more alike these two fields appear to be. Justin Clarke-Doane argues that they are very much alike indeed, especially when it comes to questions of “reality” and “objectivity” — but that they aren’t quite exactly analogous. We get a little bit into the weeds, but this is a case where close attention will pay off.Support Mindscape on Patreon.Justin Clarke-Doane received his Ph.D. in philosophy from New York University.

The internet has made it so much easier for people to talk to each other, in a literal sense. But it hasn’t necessarily made it easier to have rewarding, productive, good-faith conversations. Here I talk with sociologist Rod Graham about what kinds of conversations the internet does enable, and should enable, and how we can work to make them better. We discuss both how social media are used for nefarious purposes, from cyberbullying to driving extremism, but also how they can be mobilized for more lofty goals. We also get into some of the lost nuances in conventional discussions of race, including how many minorities are more culturally conservative than an oversimplified narrative would lead us to believe, and the tricky relationship between online discourse and social cohesion.Support Mindscape on Patreon.Roderick Graham received his Ph.D. in sociology from the City University of New York.

In our postmodern world, studying the classics of ancient Greece and Rome can seem quaint at best, downright repressive at worst. (We are talking about works by dead white men, after all.) Do we still have things to learn from classical philosophy, drama, and poetry? Shadi Bartsch offers a vigorous affirmative to this question in two new books coming from different directions. First, she has newly translated the Aeneid, Vergil’s epic poem about the founding myth of Rome, bringing its themes into conversation with the modern era. Second, in the upcoming Plato Goes to China, she explores how a non-Western society interprets classic works of Western philosophy, and what that tells us about each culture.Support Mindscape on Patreon.Shadi Bartsch-Zimmer received her Ph.D. in Classics from the University of California, Berkeley.

A common argument against free will is that human behavior is not freely chosen, but rather determined by a number of factors. So what are those factors, anyway? There’s no one better equipped to answer this question than Robert Sapolsky, a leading psychoneurobiologist who has studied human behavior from a variety of angles. In this conversation we follow the path Sapolsky sets out in his bestselling book Behave, where he examines the influences on our behavior from a variety of timescales, from the very short (signals from the amygdala) to the quite ancient (genetic factors tracing back tens of thousands of years and more). It’s a dizzying tour that helps us understand the complexity of human action.Support Mindscape on Patreon.Robert Sapolsky received his Ph.D. in neuroendocrinology from Rockefeller University.

It’s a truism that what we see about the world is a small fraction of all that exists. At the simplest level of physics and biology, our senses are drastically limited; we only see a narrow spectrum of electromagnetic waves, and we only hear a narrow band of sound. We don’t feel neutrinos or dark matter at all, even as they pass through our bodies, and we can’t perceive microscopic objects. While science can help us overcome some of these limitations, they do shape how we think about the world. Ziya Tong takes this idea and expands it to include the parts of our social and moral worlds that are effectively invisible to us — from where our food comes from to how we decide how wealth is allocated in society.Support Mindscape on Patreon.Ziya Tong received a B.A. in psychology and sociology from the University of British Columbia, and an M.A. in communications from McGill University.

As a semi-outsider, it’s fun for me to watch as a new era dawns in biology: one that adds ideas from physics, big data, computer science, and information theory to the usual biological toolkit. One of the big areas of study in this burgeoning field is the relationship between the basic bioinformatic building blocks (genes and proteins) to the macroscopic organism that eventually results. That relationship is not a simple one, as we’re discovering. Standard metaphors notwithstanding, an organism is not a machine based on genetic blueprints. I talk with biologist and information scientist Michael Levin about how information and physical constraints come together to make organisms and selves.Support Mindscape on Patreon.Michael Levin received his Ph.D. in genetics from Harvard University.

The possible existence of technologically advanced extraterrestrial civilizations — not just alien microbes, but cultures as advanced (or much more) than our own — is one of the most provocative questions in modern science. So provocative that it’s difficult to talk about the idea in a rational, dispassionate way; there are those who loudly insist that the probability of advanced alien cultures existing is essentially one, even without direct evidence, and others are so exhausted by overblown claims in popular media that they want to squelch any such talk. Astronomer Avi Loeb thinks we should be taking this possibility seriously, so much so that he suggested that the recent interstellar interloper `Oumuamua might be a spaceship built by aliens. That got him in a lot of trouble.

What is the world made of? How does it behave? These questions, aimed at the most basic level of reality, are the subject of fundamental physics. What counts as fundamental is somewhat contestable, but it includes our best understanding of matter and energy, space and time, and dynamical laws, as well as complex emergent structures and the sweep of the cosmos. Few people are better positioned to talk about fundamental physics than Frank Wilczek, a Nobel Laureate who has made significant contributions to our understanding of the strong interactions, dark matter, black holes, and condensed matter, as well as proposing the existence of time crystals.

The first full week of 2021 has been action-packed for those of us in the United States of America, for reasons you’re probably aware of, including a riotous mob storming the US Capitol. The situation has spurred me to take the unusual step of doing a solo podcast in response to current events. But never fear, I’m not actually trying to analyze current events for their own sakes. Rather, I’m using them as a jumping-off point for a more general discussion of how democracy is supposed to work and how we can make it better. We’ve talked about related topics recently with Cornel West and David Stasavage, but there are things I wanted to say in my own voice that fit well here. Politics is important everywhere, and it’s a crucial responsibility for those of us who live in societies that aspire to be participatory and democratic.

We all know stereotypes about people from different countries; but we also recognize that there really are broad cultural differences between people who grow up in different societies. This raises a challenge when most psychological research is performed on a narrow and unrepresentative slice of the world’s population — a subset that has accurately been labeled as WEIRD (Western, Educated, Industrialized, Rich, and Democratic). Joseph Henrich has argued that focusing on this group has led to systematic biases in how we think about human psychology. In his new book, he proposes a surprising theory for how WEIRD people got that way, based on the Church insisting on the elimination of marriage to relatives. It’s an audacious idea that nudges us to rethink how the WEIRD world came to be.Support Mindscape on Patreon.Joseph Henrich received his Ph.D. in anthropology from UCLA.

Welcome to the third annual Mindscape Holiday Message! Just a chance for me to be a little more chatty and informal than usual, although as it turned out this isn’t all that different from a conventional solo episode. With the difference that what I’m talking about — a phenomenon called “cosmic birefringence” — has played a big part in my personal scientific career, so I get to be a bit autobiographical.Every photon has a direction of polarization, which generally remains fixed as the photon travels through space. Birefringence is an effect by which the polarization rotates rather than staying fixed. It can happen in materials, but generally not in outer space. But there are exotic physics ideas that could cause such a rotation, including the dynamical dark energy candidate known as quintessence. People have put limits on such cosmic birefringence for a while now, but recently there was a claim that there might be a nonzero amount of birefringence visible in the polarization of the cosmic microwave background! Still very tentative, but if this hint turns into real evidence, it would big extremely big news for our understanding of physics and cosmology, possibly helping us pinpoint the nature of dark energy.Show notes, links, transcript: https://www.preposterousuniverse.com/podcast/2020/12/21/holiday-message-2020-the-screwy-universe/See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Many characteristics go into making human beings special — brain size, opposable thumbs, etc. Surely one of the most important is language, and in particular the ability to learn new sounds and use them for communication. Many other species communicate through sound, but only a very few — humans, elephants, bats, cetaceans, and a handful of bird species — learn new sounds in order to do so. Erich Jarvis has been shedding enormous light on the process of vocal learning, by studying birds and comparing them to humans. He argues that there is a particular mental circuit in the brains of parrots (for example) responsible for vocal learning, and that it corresponds to similar circuits in the human brain. This has implications for the development of intelligence and other important human characteristics.Support Mindscape on Patreon.Erich Jarvis received his Ph.D. in Animal Behavior and Molecular Neurobehavior from Rockefeller University.

Those of us living in democracies tend to take the idea for granted. We forget what an audacious, radical idea it is to put government power into the hands of literally all of the citizens of a country. Where did such an idea come from, and where is it going? Political scientist David Stasavage has written an ambitious history of democracy worldwide, in which he makes a number of unconventional points. The roots of democracy go much further back than we often think; the idea wasn’t invented in Athens, but can be found in a large number of ancient societies. And the resurgence of democracy in Europe wasn’t because that continent was especially advanced, but precisely the opposite. These insights have implications for what the future of democracy has in store.Support Mindscape on Patreon.David Stasavage received his Ph.D. in Government from Harvard University.

Aristotle conceived of the world in terms of teleological “final causes”; Darwin, or so the story goes, erased purpose and meaning from the world, replacing them with a bloodless scientific algorithm. But should we abandon all talk of meanings and purposes, or instead conceptualize them as emergent rather than fundamental? Philosophers (and former Mindscape guests) Alex Rosenberg and Daniel Dennett recently had an exchange on just this subject, and today we’re going to hear from a working scientist.

Time! It doesn’t stop, psychological effects of being under lockdown notwithstanding. How we experience time depends on our situation, but time itself just marches forward. Unless, of course, it’s possible to travel to the past, as countless science-fiction scenarios have depicted. But does that really make sense? Couldn’t we then change the past, even so dramatically that our own existence would never have happened? In this solo podcast I talk about both the physics and fiction of time travel. I point out that it might be allowed by the laws of physics, and explain how that would work, but that we really don’t know. And I try to make sense of some of the less-sensible depictions of cinematic time travel.

As you have likely heard me mention before, I have an account on Patreon, where people can sign up to donate a dollar or two per episode of Mindscape. In return they get two tangible (if minor) benefits. First, they get to listen to the podcast without any ads. Second, once per month I do an Ask Me Anything episode, where patrons are allowed to ask any question they like, and I do my best to answer as many as I can.Patreon supporters have kindly agreed to let these monthly AMA episodes be released to the general public (though they maintain the right actually ask the questions). I announced that I’d be doing this a while back, but with the cost structure I had with my podcast host it turned out to be prohibitively expensive for me. But now we’ve got that all figured out! So now, and hopefully going forward, these AMAs will be part of the regular podcast feed.

Emotions are at the same time utterly central to who we are — where would we be without them? — and also seemingly peripheral to the “real” work our brains do, understanding the world and acting within it. Why do we have emotions, anyway? Are they hardwired into the brain? Lisa Feldman Barrett is one of the world’s leading experts in the psychology of emotions, and she emphasizes that they are more constructed and less hard-wired than you might think.

Imagine you were locked in a sealed room, with no way to access the outside world but a few screens showing a view of what’s outside.

In the service of seeking truth, there would seem to be value in intellectual diversity, both in keeping ourselves honest and in the possibility of new ideas coming from unexpected quarters. That’s true in the natural sciences, but even more so in the humanities and social sciences, where the right/wrong distinction is sometimes less clear. But academia isn’t always diverse; as an empirical fact, there are a lot more liberals on university faculties than there are conservatives. I talk with Musa al-Gharbi about why this is true — self-selection? discrimination? — the extent to which it’s a real problem, and how we should better think about the value of diverse viewpoints.Support Mindscape on Patreon.Musa al-Gharbi received Masters degrees in philosophy from the University of Arizona and in sociology from Columbia University.

Astronomers rocked the cosmological world with the 1998 discovery that the universe is accelerating. Well-deserved Nobel Prizes were awarded to Saul Perlmutter, Brian Schmidt, and today’s guest Adam Riess. Adam has continued to push forward on investigating the structure and evolution of the universe. He’s been a leader in emphasizing a curious disagreement that threatens to grow into a crisis: incompatible values of the Hubble constant (expansion rate of the universe) obtained from the cosmic microwave background vs. direct measurements.

Evolution 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.

How can, and should, we talk to each other, especially to people with whom we disagree? “Free speech” is rightfully entrenched as an important value in liberal democratic societies, but implementing it consistently and fairly is a tricky business. Political theorist Teresa Bejan comes to this question from a philosophical and historical perspective, managing to relate broad principles to modern hot-button issues.

Stephen Hawking made a number of memorable contributions to physics, but perhaps his greatest was a puzzle: what happens to information that falls into a black hole? The question sits squarely at the overlap of quantum mechanics and gravitation, an area in which direct experimental input is hard to come by, so a great number of leading theoretical physicists have been thinking about it for decades. Now there is a possibility that physicists might have made some progress, by showing how subtle effects relate the radiation leaving a black hole to what’s going on inside. Netta Engelhardt is one of the contributors to these recent advances, and together we go through the black hole information puzzle, why wormholes might be important to the story, and what it all might teach us about quantum gravity.Support Mindscape on Patreon.Netta Engelhardt received her Ph.D. in physics from the University of California, Santa Barbara.

Sexuality is, and always has been, a topic that is endlessly fascinating but also contentious. You might think that asexuality would be more straightforward, but you’d be wrong. Asexual people, or “aces,” haven’t been front and center in the public discussion of gender and sexuality, and as a result there is confusion about such basic issues as what “asexuality” even means. Angela Chen is a science journalist and an ace herself, and she’s written a new book about asexuality and how it fits into the wider discussion of sex and gender. Precisely because sexuality is so taken for granted by many people, thinking about asexuality not only helps us understand the issues confronting aces, but the meaning of sexuality more broadly.Support Mindscape on Patreon.Angela Chen received a B.A. in comparative literature from UC San Diego.

You can’t always get what you want, as a wise person once said. But we do try, even when someone else wants the same thing. Our lives as people, and the evolution of other animals over time, are shaped by competition for scarce resources of various kinds. Game theory provides a natural framework for understanding strategies and behaviors in these competitive settings, and thus provides a lens with which to analyze evolution and human behavior, up to and including why racial or gender groups are consistently discriminated against in society.

Not too long ago nobody carried a mobile phone; now almost everybody does. That’s the kind of rate of rapid progress we’re seeing with our ability to directly edit genomes.

Human civilization is only a few thousand years old (depending on how we count). So if civilization will ultimately last for millions of years, it could be considered surprising that we’ve found ourselves so early in history. Should we therefore predict that human civilization will probably disappear within a few thousand years? This “Doomsday Argument” shares a family resemblance to ideas used by many professional cosmologists to judge whether a model of the universe is natural or not. Philosopher Nick Bostrom is the world’s expert on these kinds of anthropic arguments.

Physicists 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 characterize such behavior. Then we talk about information networks in the modern world, including how they have been used to spread disinformation and find recruits for radical fringe groups.Support Mindscape on Patreon.Neil Johnson received his Ph.D. in physics from Harvard University.

We are living, in case you haven’t noticed, in a world full of bullshit.

Despite 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.

Someday, 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.

We 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.

Creativity 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?

A 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 human meaning in a world where values are not imposed on us or objectively grounded in physical facts.I think life does have meaning, and it’s important to understand what forms it might take. I settle largely on the idea that humans can conceive of different possible futures, assign value to them, and work against the natural order of things to create something that otherwise would not have been. This is far from the final word, even in my own mind; it’s an invitation to think and converse in a reasonable way about some of the biggest questions there are. Just like the podcast in general.Support Mindscape on Patreon.Here are some modern works offering other perspectives on the meaning of life:Owen Flanagan, The Really Hard Problem: Meaning in a Material WorldSusan Wolf, Meaning in Life and Why it MattersTerry Eagleton, The Meaning of Life: A Very Short IntroductionJulian Baggini, What’s It All About?

There 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 we consider quantum computers as well as classical ones.
