The number of neurons in the human brain is comparable to the number of stars in the Milky Way galaxy. Unlike the stars, however, in the case of neurons the real action is in how they are directly connected to each other: receiving signals over synapses via their dendrites, and when appropriately triggered, sending signals down the axon to other neurons (glossing over some complications). So a major step in understanding the brain is to map its wiring diagram, or connectome: the complete map of those connections. For a human brain that's an intimidatingly complex challenge, but important advances have been made on tinier brains. We talk with Jeff Lichtman, a leader in brain mapping, to gauge the current state of progress and what it implies.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/12/09/298-jeff-lichtman-on-the-wiring-diagram-of-the-brain/Jeff Lichtman received an MD/PhD from Washington University in St. Louis.

Not too long ago, Brad Pitt and Eric Bana starred in a (loose) adaptation of Homer's epic poem The Iliad; next month, Ralph Fiennes and Juliette Binoche will headline a film based on The Odyssey. Given that the originals were written (or at least written down) in the 8th century BCE, that is some impressive staying power. But they were also written in a very different time than ours, with different cultural context and narrative expectations. We talk about the issues of translation in general, and these Greek classics in particular, with Emily Wilson, whose recent translations of The Iliad and The Odyssey have garnered worldwide acclaim.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/11/25/297-emily-wilson-on-homer-poetry-and-translation/Emily Wilson received her Ph.D. in classical and comparative literature from Yale.

Biological evolution via natural selection is a simple idea that becomes enormously complicated in its realization. Populations of organisms are driven toward increased "fitness," a measure of how successfully we reproduce our genetic information. But fitness is a subtle concept, changing with time and environment and interactions with other organisms around us. We talk with biologist Brandon Ogbunu about the best mathematical and conceptual tools for thinking about the messy complexities of evolution, and how modern technology is changing our way of thinking about it.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/11/18/296-brandon-ogbunu-on-fitness-seascapes-and-the-course-of-evolution/Brandon Ogbunu received his Ph.D. in Genetics and Microbiology from Yale University.

Emergence is a centrally important concept in science and philosophy. Indeed, the existence of higher-level emergent properties helps render the world intelligible to us -- we can sensibly understand the macroscopic world around us without a complete microscopic picture. But there are various different ways in which emergence might happen, and a tendency for definitions of emergence to rely on vague or subjective criteria. Recently Achyuth Parola and I wrote a paper trying to clear up some of these issues: What Emergence Can Possibly Mean. In this solo podcast I discuss the way we suggest to think about emergence, with examples from physics and elsewhere.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/11/11/295-solo-emergence-and-layers-of-reality/Support Mindscape on Patreon.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Erwin Schrödinger said that the important characteristic of life is that it "goes on doing something... for a much longer period than we would expect an inanimate piece of matter to keep going under similar circumstances." Living organisms are in constant motion inside; so where does this stability and persistence come from? Addy Pross points to a novel kind of chemical phenomenon -- "dynamic kinetic stability" (DKS), a feature that enables a chemical "fountain" to persist in the presence of an energy source. This suggests an interesting perspective on the question of life's origin, and perhaps on the origin of consciousness.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/10/28/294-addy-pross-on-dynamics-stability-and-life/Addy Pross received his Ph.D. in chemistry from the University of Sydney.

A large economy is one of the best examples we have of complex dynamics. There are multiple components arranged in complicated overlapping hierarchies, out-of-equilibrium dynamics, nonlinear coupling and feedback between different levels, and ubiquitous unpredictable and chaotic behavior. Nevertheless, many economic models are based on relatively simple equilibrium principles. Doyne Farmer is among a group who think that economists need to start taking the tools of complexity theory seriously, as he argues in his recent book Making Sense of Chaos: A Better Economics for a Better World.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/10/21/293-doyne-farmer-on-chaos-crashes-and-economic-complexity/J.

It's not immoral to kick a rock; it is immoral to kick a baby. At what point do we start saying that it is wrong to cause pain to something? This question has less to do with "consciousness" and more to do with "sentience" -- the ability to perceive feelings and sensations. Philosopher Jonathan Birch has embarked on a careful study of the meaning of sentience and how it can be identified in different kinds of organisms, as he discusses in his new open-access book The Edge of Sentience. This is an example of a question at the boundary of philosophy and biology with potentially important implications for real-world policies.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/10/14/292-jonathan-birch-on-animal-sentience/Jonathan Birch received his Ph.D. in the philosophy of science from the University of Cambridge.

Aging and death happen to the best of us, but there are increasing efforts to do something about it. That effort requires that we have some reasonable understanding of why aging happens, and what processes are involved. You will be unsurprised to learn that it's complicated. Venki Ramakrishnan, who won the Nobel Prize for his work on the ribosome, investigates what we know about aging in his book Why We Die: The New Science of Aging and the Quest for Immortality. We talk about aging and death, and manage to get some thoughts in about ribosomes. Venki and many other great communicators will be speaking at New Scientist Live, which takes place at ExCeL London between 12 - 14 October 2024, and is also streamed live as well as on-demand.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/09/30/291-venki-ramakrishnan-on-the-biology-of-death-and-aging/Venkatraman (Venki) Ramakrishnan received his Ph.D. in physics from Ohio University.

It's a wonder democracy works at all -- a collection of people with potentially different interests have to agree to abide by majority vote even when it goes against their desires. But as we know, it doesn't always work, and racial and ethnic tensions are one of its biggest challenges. Hahrie Han studies the ground-up workings of democracy, how people can come together to successfully enact change. In her new book Undivided: The Quest for Racial Solidarity in an American Church, she investigates an example where democracy apparently has worked remarkably well, and asks what lessons we can draw from it.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/09/23/290-hahrie-han-on-making-multicultural-democracy-work/Hahrie Han recieved her Ph.D. in political science from Stanford University.

As an experimental facility, the Large Hadron Collider at CERN in Geneva has been extraordinarily successful, discovering the Higgs boson and measuring multiple features of particle-physics interactions at unprecedented energies. But to theorists, the results have been somewhat frustrating, as we were hoping to find brand-new phenomena beyond the Standard Model. There is nothing to do but to keep looking, recognizing that we have to choose our methods judiciously. I talk with theoretical physicist Cari Cesarotti about what experimental results the modern particle physicist most looks forward to, and how we might eventually get there, especially through the prospect of a muon collider.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/09/16/289-cari-cesarotti-on-the-next-generation-of-particle-experiments/Cari Cesarotti received her Ph.D. in physics from Harvard University.

It wasn't that long ago, historically speaking, that you might put on your tuxedo or floor-length evening gown to go out and hear a live opera or symphony. But today's world is faster, more technologically connected, and casual. Is there still a place for classical music in the contemporary environment? Max Richter, whose new album In a Landscape releases soon, proves that there is. We talk about what goes into making modern classical music, how musical styles evolve, and why every note should count.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/09/09/288-max-richter-on-the-meaning-of-classical-music-today/Max Richter trained in composition and piano at Edinburgh University, at the Royal Academy of Music, and with Luciano Berio in Florence.

One common feature of complex systems is sensitive dependence on initial conditions: a small change in how systems begin evolving can lead to large differences in their later behavior. In the social sphere, this is a way of saying that history matters. But it can be hard to quantify how much certain specific historical events have affected contemporary conditions, because the number of variables is so large and their impacts are so interdependent. Political economist Jean-Paul Faguet and collaborators have examined one case where we can closely measure the impact today of events from centuries ago: how Colombian communities are still affected by 16th-century encomienda, a colonial forced-labor institution. We talk about this and other examples of the legacy of history.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/08/26/287-jean-paul-faguet-on-institutions-and-the-legacy-of-history/Jean-Paul Faguet received a Ph.D. in Political Economy and an M.Sc. in Economics from the London School of Economics, and an Master of Public Policy from the Kennedy School of Government at Harvard.

Understanding how life began on Earth involves questions of chemistry, geology, planetary science, physics, and more. But the question of how random processes lead to organized, self-replicating, information-bearing systems is a more general one. That question can be addressed in an idealized world of computer code, initialized with random sequences and left to run. Starting with many such random systems, and allowing them to mutate and interact, will we end up with "lifelike," self-replicating programs? A new paper by Blaise Agüera y Arcas and collaborators suggests that the answer is yes. This raises interesting questions about whether computation is an attractor in the space of relevant dynamical processes, with implications for the origin and ubiquity of life.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/08/19/286-blaise-aguera-y-arcas-on-the-emergence-of-replication-and-computation/Blaise Agüera y Arcas received a B.A. in physics from Princeton University.

Being rational necessarily involves engagement with probability. Given two possible courses of action, it can be rational to prefer the one that could possibly result in a worse outcome, if there's also a substantial probability for an even better outcome. But one's attitude toward risk -- averse, tolerant, or even seeking -- also matters. Do we work to avoid the worse possible outcome, even if there is potential for enormous reward? Nate Silver has long thought about probability and prediction, from sports to politics to professional poker. In his his new book On The Edge: The Art of Risking Everything, Silver examines a set of traits characterizing people who welcome risks.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/08/12/285-nate-silver-on-prediction-risk-and-rationality/Nate Silver received a B.A. in economics from the University of Chicago.

The human brain does a pretty amazing job of taking in a huge amount of data from multiple sensory modalities -- vision, hearing, smell, etc. -- and constructing a coherent picture of the world, constantly being updated in real time. (Although perhaps in discrete moments, rather than continuously, as we learn in this podcast...) We're a long way from completely understanding how that works, but amazing progress has been made in identifying specific parts of the brain with specific functions in this process. Today we talk to leading neuroscientist Doris Tsao about the specific workings of vision, from how we recognize faces to how we construct a model of the world around us.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/07/29/284-doris-tsao-on-how-the-brain-turns-vision-into-the-world/Doris Tsao received her Ph.D. in neurobiology from Harvard University.

The the physics podcast about Emergence (a very cool) topic and i need to listen to political divinations about the next 4y? Dude.
Sounds fine to me
Audio of the guest is terrible unless you are in a studio.
AMA is just a money maker for Sean. Who wants to listen to over an hour of random silliness.
how hard he tries to hide his self-loathing is almost laughable. Love this podcast, but this episode is just embarrasing.
definitely one of the best podcasts ive listened to tnx to u both
what a great episode! Perfectly confirmed my biases! Seriously. put structure to my own research and reasoning.
Octopuses.. Isn't it octopodes? I'm not an English major, but now it drives me crazy 🙈
4 hours?! Need to limit these AMAs and keep them focused on physics, I'm not interested in what a physicist has to say about politics, social science, or other topics out of their area of expertise
love the content but can't deal with commercial breaks in the middle of a conversation. They should all be at the beginning so the rest is uninterrupted. I will always listen to the full ads when they're at the beginning. It's my way of understanding that money needs to be made. Thanks but I will pass for now.
Who’s listening to Greta?
xqzh. dmi
he claims no other animals point for purposes of communication, but what about ants which point to food with chemicals and bees that point to flowers with dance?
Wow, a new perspective on Karl Friston's ideas
Really interesting subjects and a great amount of wisdom in this interview, however it kinda feels rushed. I'd also love to hear Sean's own take a bit more in conversation.
This is a description of how miracles could occur. Note destruction is required first.
tell this bitch to stfu and let my boy ask God Damn questions jesus
I enjoyed listening to every bit of this episode!👍

Taiwan's amazing democracy may a model for the future, I think. The Taiwanese government doesn't weigh the input of its population on every issue, but because the world and its country are so interconnected by computer it's taking advantage of. It's representative and in cases where expertise is paramount, decisions like military engagements are made by Representatives elected by the people. So it's direct democracy wherever possible. In the US, I cannot imagine it the near future but we should do this on a local level and then try it in a state. This degree of direct democracy and Blockchain ledgers for every government dollar appropriated, contracts bid out, the project's bids, are the future of democratic self governance. It's about accountability to the governed. We have to demand it. Hmm. In the USA, more children are killed than police every year and we can't move the needle. 75 - 80% of Americans support meaningful policy changes to support gun safety but we need the approval, t
