Sean Carroll, theoretical physicist and philosopher, discusses complexity in physics, quantum mechanics interpretations, emergence, and challenges in academia. Topics include AI, scientific publishing, democracy, and what makes a great physicist.

Einstein's description of gravity as a curvature in space-time doesn't easily mesh with a universe made up of quantum wavefunctions. Theoretical physicist Sean Carroll (of the "Mindscape" podcast) tells Steven Strogatz about the mind-bending implications of the quest for quantum gravity.

If you scale up an animal to twice its height, keeping everything else proportionate, its volume and weight become eight times as much. Such a scaling relation was used by J.B.S. Haldane in his famous essay, "On Being the Right Size," to help explain certain features of living organisms. But scaling relations go much deeper than that, and they are often much more subtle than the volume going as the cube of the length. Geoffrey West is a particle physicist turned complexity theorist, who studies how features from metabolism to lifespan change as we adjust the size of an organism -- or of other complex systems, from cities to computer networks. His insights have important implications for innovation, sustainability, and the best ways to organize life here on Earth.

Sean Carroll, a physics expert, delves into quantum field theory, explaining measurement, entanglement, and the world being made of fields. He discusses fundamental concepts like spin, symmetry, and the Higgs mechanism, revealing the unimaginable truth about our universe. The podcast explores dark energy, dark matter, the Higgs field, and philosophical questions about the origins of the universe.

David Krakauer and Sean Carroll discuss human history's impact on scientific inquiry, from genetic causality debates to the quest for emergent laws in complex systems. They explore the balance between simplicity and complexity in physics, interdisciplinary challenges in research, and the entropic nature of life and the universe. The podcast highlights the Santa Fe Institute's role in promoting adaptive scientific inquiry.

Join Sean Carroll, a physicist and cosmologist from Johns Hopkins, Ellen Langer, a Harvard psychologist known for her work on mindfulness, and Tamar Gendler, Yale's philosophy and cognitive science expert, as they dive deep into the enigma of consciousness. They challenge if science can ever truly unravel subjective experience and explore the philosophical nuances of materialism and dualism. The discussion also tackles external world skepticism and the fascinating mind-body connection, highlighting how evolving insights can impact our understanding of reality.

This podcast explores the perplexing concept of consciousness and delves into novel explanations for its existence. Featuring interviews with prominent experts, it discusses the enigma of consciousness, its essential properties, the interplay with quantum mechanics, and controversial theories surrounding its nature.

Theoretical physicist Sean Carroll discusses the relationship between science and philosophy, delving into quantum mechanics and the possibility of parallel universes. They also touch on topics of David Weiss's testimony, Trump's revenge plans, and the compatibility between science and religion. The conversation explores the concept of time travel, both in movies and in theory, while also discussing the implications of quantum mechanics and the potential existential threat of AI.

Without a sense of time, leading us from cradle to grave, our lives would make little sense. But on the most fundamental level, physicists aren't sure whether the sort of time we experience exists at all. We talk to three experts and find out if time could potentially be moving backwards as well as forwards. Featuring Sean Carroll, Homewood professor of natural philosophy at Johns Hopkins University, Emily Adlam, postdoctoral associate of the philosophy of physics at Western University and Natalia Ares, Royal Society university research fellow at the University of Oxford.This episode was presented by Miriam Frankel and produced by Hannah Fisher.

Join Sean Carroll, a renowned physicist and podcast host, Ellen Langer, a Harvard psychologist and mindfulness expert, and Tamar Gendler, Yale’s philosophy dean. They dive into the limits of science in addressing consciousness. The trio debates how our language shapes reality and influences perceptions, particularly around mental experiences and chronic conditions. They tackle the dualism versus monism debate, questioning if materialism can truly capture the essence of our thoughts and feelings, all while pondering the profound connection between mind and body.
