340 | Rebecca Newberger Goldstein on What Matters and Why It Matters

At any given moment, an uncountable number of events are happening, but only some of them matter to us. What does it mean for something to matter, and more importantly, what does it mean for us to matter -- to ourselves as well as to others? The need to matter can be motivation to do great things, but it can also be a reason for people to come into conflict. Philosopher/novelist Rebecca Newberger Goldstein explores this issue in her new book The Mattering Instinct: How Our Deepest Longing Drives Us and Divides Us.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2026/01/12/340-rebecca-newberger-goldstein-on-what-matters-and-why-it-matters/Support Mindscape on Patreon.Rebecca Newberger Goldstein received her Ph.D. in philosophy from Princeton University.

339 | Ned Block on Whether Consciousness Requires Biology

It's become increasingly clear that the Turing Test -- determining whether human interlocutors can tell whether a conversation is being carried out by a human or a machine -- is not a good way to think about consciousness. Modern LLMs can mimic human conversation with extraordinary verisimilitude, but most people would not judge them to be conscious. What would it take? Is it even possible for a computer program to achieve consciousness, or must consciousness be fundamentally "meat-based"? Philosopher Ned Block has long argued that consciousness involves something more than simply the "functional" aspects of inputs and outputs.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2026/01/05/339-ned-block-on-whether-consciousness-requires-biology/Support Mindscape on Patreon.Ned Block received his Ph.D. in philosophy from Harvard University.

338 | Ryan Patterson on the Physics of Neutrinos

The story goes that Wolfgang Pauli, who first proposed the existence of neutrinos, was embarrassed to have done so, as it was considered uncouth to hypothesize new particles that could not be detected. Modern physicists have no such scruples, of course, but more importantly neutrinos turn out to be very detectable, given sufficient resources and experimental technique. I talk with neutrino physicist Ryan Patterson about what current and upcoming experiments teach us about neutrinos themselves, as well as implications for dark matter and why there are more particles than antiparticles in the universe.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2025/12/08/228-ryan-patterson-on-the-physics-of-neutrinos/Support Mindscape on Patreon.Ryan Patterson received his Ph.D. in physics from Princeton University.

337 | Kevin Zollman on Game Theory, Signals, and Meaning

Game theory is a way of quantitatively describing what happens any time one thing interacts with another thing, when both things have goals and potential rewards. That's a pretty broad class of interesting events, so it is unsurprising that game theory is a useful way of thinking about everything from international relations to the evolution of peacock feathers. I talk with philosopher Kevin Zollman about what game theory is and how it gets used in biology and human interactions. We discuss how thinking in game-theoretic terms can help understand the origin of meaning and intentionality in human language.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2025/12/01/337-kevin-zollman-on-game-theory-signals-and-meaning/Support Mindscape on Patreon.Kevin Zollman received his Ph.D. in philosophy from the University of California, Irvine.

336 | Anil Ananthaswamy on the Mathematics of Neural Nets and AI

Machine learning using neural networks has led to a remarkable leap forward in artificial intelligence, and the technological and social ramifications have been discussed at great length. To understand the origin and nature of this progress, it is useful to dig at least a little bit into the mathematical and algorithmic structures underlying these techniques. Anil Ananthaswamy takes up this challenge in his book Why Machines Learn: The Elegant Math Behind Modern AI. In this conversation we give a brief overview of some of the basic ideas, including the curse of dimensionality, backpropagation, transformer architectures, and more.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2025/11/24/336-anil-ananthaswamy-on-the-mathematics-of-neural-nets-and-ai/Support Mindscape on Patreon.Anil Ananthaswamy received a Masters degree in electrical engineering from the University of Washington, Seattle.

335 | Andrew Jaffe on Models, Probability, and the Universe

Science has an incredibly impressive track record of uncovering nonintuitive ideas about the universe that turn out to be surprisingly accurate. It can be tempting to think of scientific discoveries as being carefully constructed atop a rock-solid foundation. In reality, scientific progress is tentative and fallible. Scientists propose models, assign them probabilities, and run tests to see whether they succeed or fail. In cosmologist Andrew Jaffe's new book, The Random Universe, he illustrates how models and probability help us make sense of the cosmos.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2025/11/10/335-andrew-jaffe-on-models-probability-and-the-universe/Support Mindscape on Patreon.Andrew Jaffe received his Ph.D. in physics from the University of Chicago.
