The Escaped Sapiens Podcast

Recently, new AI-based techniques have begun to allow researchers to decipher ancient Greek texts from scrolls burned almost beyond recognition by the eruption of Mount Vesuvius. I wanted to understand what this breakthrough actually means. In the broader picture of our knowledge of the ancient world, how important is this new technology? In this episode of the podcast, I speak with Professor Richard Janko, one of the world’s leading scholars of ancient Greek literature, philosophy, and the transmission of texts. He begins by sketching the long arc of Greek history, before turning to his own work deciphering ancient papyri. Along the way, he explains which Greek texts have survived, what they can tell us about everyday life, religion, poetry, and philosophy, and why the newly emerging material matters. What unfolds is a story of the Greeks themselves-their ideas, their sense of the world, and what life was like more than two thousand years ago. ►Watch on Youtube: https://youtu.be/NDcxvxKtJHA

* Note: This Episode was filmed over two years ago in mid 2023. In the lead up to my own surgery I speak with Stanford and Harvard trained, board-certified anesthesiologist and integrative medicine specialist Anthony Kaveh. In addition to his medical work Anthony runs his own YouTube channel where he educates listeners about anesthetics and the therapeutic use of psychedelics. We discuss how anesthetics and psychedelics work on the brain, and what anesthesia can teach us about intelligence, perception, and mental illness. We also discuss the log term risks associated with anesthetics and the impact of the opioid crisis on operating Theaters around the US. ►Watch on YouTube: https://youtu.be/9BeBi8ZOHRk ►For more information about Anthony's work see: https://www.youtube.com/@MedicalSecrets/videos https://www.medicalsecretsmd.com/ These conversations are supported by the Andrea von Braun Foundation (http://www.avbstiftung.de/), as an exploration of the rich, exciting, connected, scientifically literate, and (most importantly) sustainable future of humanity.

What are holographic dualities, and is our universe really a hologram? In this episode of the podcast, I speak with Sabrina Pasterski, a faculty member at the Perimeter Institute for Theoretical Physics. Sabrina has attracted significant media attention over the years and has even been compared to figures like Einstein. I ask her what it was like to grow up under such intense public hype while still finding her footing as a scientist. We also explore whether the media risks being irresponsible when it constructs prodigy narratives — and what that means for young, brilliant minds trying to navigate their own paths. We then turn to the major challenges in quantum gravity — a field that lacks direct experimental data and often relies on internal consistency. Sabrina shares insights from her work in Celestial Holography, which seeks to understand quantum gravity through dual descriptions: simpler, non-gravitational theories that live in lower-dimensional spaces. ►Watch on YouTube: https://youtu.be/Uff-40hOOHw ►For more information about Sabrina and her work: www.youtube.com/@PhysicsGirl-com https://physicsgirl.com/ https://perimeterinstitute.ca/people/sabrina-pasterski https://en.wikipedia.org/wiki/Sabrina_Gonzalez_Pasterski

In this episode I speak with philosopher and author David Benatar. David is best known for advancing the position of philanthropic antinatalism, which holds that coming into existence is a serious harm for sentient beings. Central to his view is the asymmetry argument, which maintains that the absence of pain is good even if no one benefits from it, while the absence of pleasure is not bad unless someone is deprived of it. David also argues that our lives are significantly worse than we tend to realize, due in part to a pervasive positivity bias. He supports this claim with a range of empirical studies, including work on optimism bias, affective forecasting, and rosy retrospection. Relevant studies include: https://pmc.ncbi.nlm.nih.gov/articles/PMC3204264/ https://2024.sci-hub.se/1554/00562a7485ff9ae6371024daf5890ed0/mitchell1997.pdf https://psycnet.apa.org/record/1980-01001-001 https://www.happierlivesinstitute.org/wp-content/uploads/2022/04/Affective-forecasting.pdf At the same time, David’s antinatalist position is challenged by other philosophers, as well as by research showing that global well-being has been improving across many important metrics. Numerous studies also suggest that most people self-report being happy and that subjective well-being often remains surprisingly high even under adverse circumstances. A counter-perspective is that humans are not blind to suffering but are instead highly adaptive, and capable of overcoming life’s challenges and minimizing the impact of hardship.

At ~23:20 David and I talk past one another. At the end of the interview we add a section clarifying David's position.

For over forty years, Dutch geologist and paleontologist Jan Smit has been at the center of one of the most profound scientific detective stories of our time: the investigation into the mass extinction that ended the reign of the dinosaurs 66 million years ago. Known as the Cretaceous-Paleogene (K-Pg) extinction, this event wiped out nearly 75% of all species on Earth, from towering dinosaurs to microscopic marine life, and cleared the way for the rise of mammals and, eventually, humans. Early in his career, Jan Smit became intrigued by a thin layer of clay found in rock strata across the globe, precisely at the boundary between Cretaceous and Paleogene sediments. This layer, unusually rich in the rare element iridium, held clues that would eventually transform our understanding of planetary history. Working alongside Luis and Walter Alvarez and others, Jan helped develop the hypothesis that a massive asteroid impact, rather than volcanic activity or gradual climate change, was the primary cause of the extinction. In this episode, we explore the extraordinary evidence for that theory: global patterns of shocked quartz, tsunami deposits, a massive crater buried beneath the Yucatán Peninsula, and the sudden disappearance of entire ecosystems in the fossil record. Jan walks us through decades of fieldwork and analysis that revealed the incredible violence and planetary consequences of the impact, a blast more powerful than a billion Hiroshima bombs, throwing Earth into a global winter. But this is more than a forensic tale of catastrophe. It's a window into the fragility and resilience of life, the interconnectedness of geological and biological systems, and the awe-inspiring forces that shape the story of our planet.

For over three decades, Felix Finster has been developing a unique and ambitious reformulation of physics known as Causal Fermion Systems (CFS). Physicists usually describe the world in terms of fields defined on a spacetime manifold. Within this familiar framework, abstract quantities such as correlations between matter fields at different points in spacetime can be computed. In mathematical language, these correlations are captured by operators acting on a Hilbert space. What Felix realized is that this process can be reversed. If you start with a suitable collection of operators on a Hilbert space, satisfying certain mathematical properties, you can in principle reconstruct the underlying spacetime and fields that would give rise to those operators as operators of correlations. In this sense, Causal Fermion Systems offers a dual description of reality. On the one hand, reality can be described in terms of symmetries, fields, and manifolds - the usual language of physics. On the other hand, CFS proposes that reality can just as well be described using abstract structures: Hilbert spaces, operators, and measures on sets of operators. Spacetime, matter, and everything we observe then emerges from these underlying mathematical quantities. The beauty of reformulating physics this way is that it opens up an entirely new framework in which to explore some of the deepest open questions in physics: What is spacetime like at the smallest scales? Why do we see precisely the particles we do in experiments? The hope is that within the CFS framework, answers to such questions might become more natural or even inevitable. Of course, we can’t cover a 30-year research program in full detail in a single conversation. The goal here is to get a sense of the flavor of Felix’s approach to physics. For the full details, you can explore Felix's books (e.g. https://www.cambridge.org/core/books/causal-fermion-systems/CCA6DE1E1F4DA3AC0EF6729664A5D5B9 ). ►Watch on YouTube: https://youtu.be/qQl51qifus0 ►Find out more about Felix's work here: https://www.uni-regensburg.de/mathematik/mathematik-1/startseite/index.html https://causal-fermion-system.com/

Aging has long been treated as inevitable. But what if it’s not? What if aging is, at its core, a problem to be solved? In this episode, I speak with biomedical gerontologist Aubrey de Grey about the most ambitious anti-aging experiment ever conducted on mice. The Robust Mouse Rejuvenation (RMR) study, spearheaded by Aubrey and the Longevity Escape Velocity Foundation, aims to extend both the average and maximum lifespan of mice by at least 12 months—a staggering leap in a species that typically lives around 30 months. We unpack the science behind this bold endeavor: What is aging? Why aim for rejuvenation and damage repair as opposed to slowing down aging? What interventions are being trialed in mice? What are the best achievable results? What does the blueprint for longevity escape velocity look like? ►Watch on YouTube: https://youtu.be/YiX5GKDtYWY ►Find out more about Aubrey's work here: https://www.levf.org/team https://www.levf.org/projects/robust-mouse-rejuvenation-study-1/study-updates

Richard Feynman once dubbed turbulence “the last unsolved problem of classical physics.” Beyond the Navier–Stokes equations, no comprehensive statistical framework exists to predict how fluids spin, eddy, and cascade energy—whether in galactic jets, ocean currents, or the swirl of your morning coffee. But that might all be changing. In this episode, I sit down with theoretical physicist Sasha Migdal, who emerged from retirement with a bold, loop‑equation approach to turbulence. His formalism recasts the Navier–Stokes equations as an infinite number of linear, readily solvable equations that track circulation around closed loops in the fluid—offering, for the first time, a tractable statistical framework for chaotic flow. We chart Sasha’s remarkable journey: from a promising career at the Landau Institute and Russian Space Institutes, where he resisted KGB pressure to compromise his work, to his defection to the United States in the late 1980s. We discuss his time outside of physics, and then delve into his return, and his novel approach to solving Navier–Stokes. Since we recorded, his theory has advanced rapidly. A rigorous proof now shows that it is the solution to the Navier–Stokes (NS) loop equation. The theory has also been extended to magnetohydrodynamics and turbulent mixing. Recent large-scale direct numerical simulations (DNS) match the theoretical predictions with even greater accuracy. ►Watch On YouTube: https://youtu.be/BNORi7mxxzg ►Find out more about Sasha's work here: https://alexandermigdal.com/ https://sashamigdal.github.io/TurbulenceDuality/index.html ►For a more technical overview of Sasha's work you can check out his recent talk at the IAS: https://www.youtube.com/watch?v=mgvGA6q7oPY

In this conversation I ask Professors Sam Richards & Laurey Mulvey about some of the most controversial topics concerning race and ethnicity in the US today. Is White Privilege a useful term that helps build understanding and facilitates conversation, or does it generate social tension and make poor white people feel gaslit? What is DEI, why is it so contentious, and can it be implemented effectively? What makes the N-word and blackface so triggering? Why are US racial social norms so culturally dominant and readily exported? Sam Richards is a sociologist and Teaching Professor at Penn State and a Distinguished Professor at Konkuk University in Seoul, Korea. He runs SOC119, which is the largest race, ethnicity and cultural relations course in the world. Every Tuesday and Thursday afternoon his class is live streamed to 370,000 subscribers from around the world, and his classes have had over 400 million views. His willingness to challenge orthodox thinking led him to be named one of the “101 Most Dangerous Professors in America” and together with Laurie Mulvey is one of the “parents of radical empathy.” Laurie Mulvey is the director and co-founder of the World in Conversation Center for Public Diplomacy at Penn State, which is the largest dialogue center in the United States, hosting more than 17,000 participants each academic year. The Center has worked with the UNDP, UNESCO, and NATO, along with organizations and universities in Afghanistan, Pakistan, Iran, Palestinian Territories, Israel, Kuwait, Qatar, China, Haiti, Saudi Arabia, and twelve nations in the NATO Alliance to host dialogues between people separated by vast distances and borders. Laurie is a master facilitator, focused on moderating beneficial conversations between different groups on some of the most difficult, hot button topics. ►Watch on YouTube: https://youtu.be/wd2DytWSAYE ►Find out more about Sam's work here: https://sociology.la.psu.edu/people/sam-richards/ ►Find out more about Laurie's work here: https://sociology.la.psu.edu/people/laurie-mulvey/ These conversations are supported by the Andrea von Braun foundation (http://www.avbstiftung.de/), as an exploration of the rich, exciting, connected, scientifically literate, and (most importantly) sustainable future of humanity.

What is Holography and how does it help us Quantize gravity? In this conversation I speak with Pedro Vieira, one of the worlds leading experts on holographic dualities and their application in quantum gravity. We start our discussion with a few standard but big questions, like why is quantum gravity difficult, what is quantum field theory, and what is gauge symmetry. We then dive into the topic of holography, which in broad and provocative terms is the idea that our universe and everything in it might be a hologram projected from some lower dimensional quantum theory. That is, there might be a duality between the mathematics that describes our world including gravity and the mathematics that describes a world with quantum mechanics and without gravity in one dimension lower. If such a duality were true, then it might provide a radial way of side stepping all of the usual difficulties of quantizing gravity. ►Watch on YouTube: https://youtu.be/FdpVxLq_PAk ►Find out more about Pedro here: https://perimeterinstitute.ca/people/pedro-vieira https://inspirehep.net/authors/1027784 These conversations are supported by the Andrea von Braun foundation (http://www.avbstiftung.de/), as an exploration of the rich, exciting, connected, scientifically literate, and (most importantly) sustainable future of humanity.
