Science is enabled by the fact that the natural world exhibits predictability and regularity, at least to some extent. Scientists collect data about what happens in the world, then try to suggest "laws" that capture many phenomena in simple rules. A small irony is that, while we are looking for nice compact rules, there aren't really nice compact rules about how to go about doing that. Today's guest, Leslie Valiant, has been a pioneer in understanding how computers can and do learn things about the world. And in his new book, The Importance of Being Educable, he pinpoints this ability to learn new things as the crucial feature that distinguishes us as human beings. We talk about where that capability came from and what its role is as artificial intelligence becomes ever more prevalent.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/04/15/272-leslie-valiant-on-learning-and-educability-in-computers-and-people/Support Mindscape on Patreon.Leslie Valiant received his Ph.D. in computer science from Warwick University.

Welcome to the April 2024 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. Enjoy!Blog post with questions and transcript: https://www.preposterousuniverse.com/podcast/2024/04/08/ama-april-2024/See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Einstein's theory of general relativity has been our best understanding of gravity for over a century, withstanding a variety of experimental challenges of ever-increasing precision. But we have to be open to the possibility that general relativity -- even at the classical level, aside from any questions of quantum gravity -- isn't the right theory of gravity. Such speculation is motivated by cosmology, where we have a good model of the universe but one with a number of loose ends. Claudia de Rham has been a leader in exploring how gravity could be modified in cosmologically interesting ways, and we discuss the current state of the art as well as future prospects.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/04/01/271-claudia-de-rham-on-modifying-general-relativity/Support Mindscape on Patreon.Claudia de Rham received her Ph.D. in physics from the University of Cambridge.

Technology is changing the world, in good and bad ways. Artificial intelligence, internet connectivity, biological engineering, and climate change are dramatically altering the parameters of human life. What can we say about how this will extend into the future? Will the pace of change level off, or smoothly continue, or hit a singularity in a finite time? In this informal solo episode, I think through what I believe will be some of the major forces shaping how human life will change over the decades to come, exploring the very real possibility that we will experience a dramatic phase transition into a new kind of equilibrium.Blog post with transcript and links to additional resources: https://www.preposterousuniverse.com/podcast/2024/03/25/270-solo-the-coming-transition-in-how-humanity-lives/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.

When it comes to social change, two questions immediately present themselves: What kind of change do we want to see happen? And, how do we bring it about? These questions are distinct but related; there's not much point in spending all of our time wanting change that won't possibly happen, or working for change that wouldn't actually be good. Addressing such issues lies at the intersection of philosophy, political science, and social dynamics. Sahar Heydari Fard looks at all of these issues through the lens of complex systems theory, to better understand how the world works and how it might be improved.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/03/18/269-sahar-heydari-fard-on-complexity-justice-and-social-dynamics/Support Mindscape on Patreon.Sahar Heydari Fard received a Masters in applied economics and a Ph.D. in philosophy from the University of Cincinnati.

In the 1860s, James Clerk Maxwell argued that light was a wave of electric and magnetic fields. But it took over four decades for physicists to put together the theory of special relativity, which correctly describes the symmetries underlying Maxwell's theory. The delay came in part from the difficulty in accepting that light was a wave, but not a wave in any underlying "aether." Today our most basic view of fundamental physics is found in quantum field theory, which posits that everything around us is a quantum version of a relativistic wave. I talk with physicist Matt Strassler about how we go from these interesting-but-intimidating concepts to the everyday world of tables, chairs, and ourselves.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/03/04/267-matt-strassler-on-relativity-fields-and-the-language-of-reality/Support Mindscape on Patreon.Matt Strassler received his Ph.D. in physics from Stanford University.

The twentieth century was something, wasn't it? Margaret Mead, as well as her onetime-husband Gregory Bateson, managed to play roles in several of its key developments: social anthropology and its impact on sex & gender mores, psychedelic drugs and their potential use for therapeutic purposes, and the origin of cybernetics, to name a few. Benjamin Breen discusses this impactful trajectory in his new book, Tripping on Utopia: Margaret Mead, the Cold War, and the Troubled Birth of Psychedelic Science. We talk about Mead and Bateson, the early development of psychedelic drugs, and how the possibility of a realistic utopia didn't always seem so far away.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/02/26/267-benjamin-breen-on-margaret-mead-psychedelics-and-utopia/Support Mindscape on Patreon.Benjamin Breen received his Ph.D. in history from the University of Texas at Austin.

Evolution is sometimes described -- not precisely, but with some justification -- as being about the "survival of the fittest." But that idea doesn't work unless there is some way for one generation to pass down information about how best to survive. We now know that such information is passed down in a variety of ways: through our inherited genome, through epigenetic factors, and of course through cultural transmission. Chris Adami suggests that we update Dobzhansky's maxim "Nothing in biology makes sense except in the light of evolution" to "... except in the light of information." We talk about information theory as a subject in its own right, and how it helps us to understand organisms, evolution, and the origin of life.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/02/19/266-christoph-adami-on-how-information-makes-sense-of-biology/Support Mindscape on Patreon.Christoph Adami received his Ph.D. in physics from Stony Brook University.
