Physics is in crisis, what else is new? That's what we hear in certain corners, anyway, usually pointed at "fundamental" physics of particles and fields. (Condensed matter and biophysics etc. are just fine.) In this solo podcast I ruminate on the unusual situation fundamental physics finds itself in, where we have a theoretical understanding that fits almost all the data, but which nobody believes to be the final answer. I talk about how we got here, and argue that it's not really a "crisis" in any real sense. But there are ways I think the academic community could handle the problem better, especially by making more space for respectable but minority approaches to deep puzzles.

Complexity scientists have been able to make an impressive amount of progress despite the fact that there is not universal agreement about what "complexity" actually is. We know it when we see it, perhaps, but there are a number of aspects to the phenomenon, and different researchers will naturally focus on their favorites. Today's guest, David Krakauer, is president of the Santa Fe Institute and a longtime researcher in complexity. He points the finger at the concept of agency. A ball rolling down a hill just mindlessly obeys equations of motion, but a complex system gathers information and uses it to adapt. We talk about what that means and how to think about the current state of complexity science.

Welcome to the July 2023 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). We take questions asked by Patreons, whittle them down to a more manageable number -- based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good -- and sometimes group them together if they are about a similar topic.

We're experimenting with a new benefit for Patreon supporters: short video (or audio-only) reflections by me on the podcast that just happened. If you've been wondering whether to join up, this could be the time.

There is an image, especially in Western cultures, of the rugged, authentic, self-made individual choosing how to navigate the intricacies of the social world. But there is no mystical soul within us, manifesting as the immutable essence of self. What we think of as our "self" is shaped by our environment and our genes, and most of all by our interactions with other people. Psychologist Brian Lowery argues for a strong version of this thesis, positing that our sense of self is largely a social construct. We talk about the implications of this idea, and what it means for shifting notions of personal identity.

Modern computers are somewhat more secure against being hacked - either by an inanimate virus or a human interloper - than they used to be. But as our lives are increasingly intertwined with computers, the dangers that hacking poses are enormously greater. Why don't we just build unhackable computers? Scott Shapiro, who is a law professor and philosopher, explains why that's essentially impossible. On a philosophical level, computers rely on an essential equivalence between "data" and "code," which is vulnerable to exploitation. And on a psychological level, human beings will always be the weakest link in the chain of security.

Is there a multiverse, and if so, how should we think of ourselves within it? In many modern cosmological models, the universe includes more than one realm, with possibly different laws of physics, and these realms may or may not include intelligent observers. There is a longstanding puzzle about how, in such a scenario, we should calculate what we, as presumably intelligent observers ourselves, should expect to see. Today's guest, Thomas Hertog, is a physicist and longstanding collaborator of Stephen Hawking. They worked together (often with James Hartle) to address these questions, and the work is still ongoing.

Eukaryotic cells manage to pull off a number of remarkable feats. One is packing quite a long DNA molecule, with potentially billions of base pairs, into a tiny central nucleus. A key role is played by histones, proteins that provide scaffolding for DNA to wrap around. Histones also appear in archaea (one of the other domains of life), but until recently there wasn't evidence for them in bacteria (the final of the three domains). Todays guest, Tobias Warnecke, is an author on a recent paper that claims to provide such evidence. We discuss this new result, as well as background questions of how cells evolved and what their current structure can teach us about their histories.

Here at the Mindscape Podcast, we are firmly pro-reason. But what does that mean, fundamentally and in practice? How did humanity come into the idea of not just doing things, but doing things for reasons? In this episode we talk with cognitive scientist Hugo Mercier about these issues. He is the co-author (with Dan Sperber) of The Enigma of Reason, about how the notion of reason came to be, and more recently author of Not Born Yesterday, about who we trust and what we believe. He argues that our main shortcoming is not being insufficiently skeptical of radical claims, but of being too skeptical of claims that don't fit our views.

If you knew exactly when every person was going to die, or require medical care, you could make a killing buying and selling insurance. Nobody knows these things, of course -- the future is hard to predict -- but some people know something about the future that other people don't. This sets up adverse selection: the ability of one party to leverage information another party doesn't have, in order to gain an economic advantage. Economist Amy Finkelstein is an expert in this phenomenon, as well as the usefulness of empirical studies in economic research.

Welcome 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 this episode. Raphaël will be sharing insights from his work in cognitive science, and discussing the latest developments in this rapidly evolving field. So join us as we dive into the mind of artificial intelligence and explore how it thinks.

Every time our brain does some thinking, there are associated physical processes. In particular, electric currents and charged particles jump between neurons, creating associated electromagnetic fields. These fields can in principle be detected with proper technology, opening the possibility for reading your mind. That technology is currently primitive, but rapidly advancing, and it's not too early to start thinking about legal and ethical consequences when governments and corporations have access to your thoughts. Nita Farahany is a law professor and bioethicist who discusses these issues in her new book, The Battle for Your Brain: Defending the Right to Think Freely in the Age of Neurotechnology.

God is dead, as Nietzsche’s madman memorably reminded us. So what are we going to do about it? If there is no powerful force out there to guide us and give meaning to our lives, how are we supposed to live? Do we have to come up with meaning and purpose ourselves? Apparently so, and how to pull it off was a major question addressed by the existentialist movement. Skye Cleary turns to Simone de Beauvoir, in particular, for thoughts on how to construct an authentic life. Her recent book is How to Be Authentic: Simone de Beauvoir and the Quest for Fulfillment.

Most of us strive to be good, moral people. When we are doing that striving, what is happening in our brains? Some of our moral inclinations seem pretty automatic and subconscious. Other times we have to sit down and deploy our full cognitive faculties to reason through a tricky moral dilemma. I talk with psychologist Molly Crockett about where our moral intuitions come from, how they can sometimes serve as cover for bad behaviors, and how morality shapes our self-image.
