Welcome to the Mindscape Podcast!

You might remember the somewhat bizarre worries that swept through certain circles back in 2012, based on the end of the world being predicted by the Maya calendar. The world didn't end, which is unsurprising because the Maya hadn't predicted that, and for that matter they had no way of doing so. But there is very interesting archeology behind our understanding of how the Maya developed their calendar, as well as other aspects of their language and scientific understanding. Mayanist David Stuart takes us on a tour of what we know and what we're still discovering.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2023/08/14/246-david-stuart-on-time-and-science-in-maya-civilization/Support Mindscape on Patreon.David Stuart received his Ph.D. in anthropology from Vanderbilt University.

Welcome to the August 2023 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/2023/08/07/ama-august-2023/See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Physics is in crisis, what else is new? That's what we hear in certain corners, anyway, usually pointed at "fundamental" physics of particles and fields. (Condensed matter and biophysics etc. are just fine.) In this solo podcast I ruminate on the unusual situation fundamental physics finds itself in, where we have a theoretical understanding that fits almost all the data, but which nobody believes to be the final answer. I talk about how we got here, and argue that it's not really a "crisis" in any real sense. But there are ways I think the academic community could handle the problem better, especially by making more space for respectable but minority approaches to deep puzzles.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2023/07/31/245-solo-the-crisis-in-physics/Support Mindscape on Patreon: https://www.patreon.com/seanmcarrollSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Is metaphysics like physics, but cooler? Or is it a relic of an outdated, pre-empirical way of thinking about the world? Closer to the former than the latter. Rather than building specific quantitative theories about the world, metaphysics aims to get a handle on the basic logical structures that help us think about it. I talk with philosopher Katie Elliott on how metaphysics helps us think about questions like counterfactuals, possible worlds, time travel, mathematical equivalence, and whether everything happens for a reason.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2023/07/24/244-katie-elliott-on-metaphysics-chance-and-time/Support Mindscape on Patreon.Katrina (Katie) Elliott received her Ph.D. in philosophy from the University of North Carolina, Chapel Hill.

The Earth's atmosphere is good for some things, like providing something to breathe. But it does get in the way of astronomers, who have been successful at launching orbiting telescopes into space. But gravity and the ground are also useful for certain things, like walking around. The Moon, fortunately, provides gravity and a solid surface without any complications of a thick atmosphere -- perfect for astronomical instruments. Building telescopes and other kinds of scientific instruments on the Moon is an expensive and risky endeavor, but the time may have finally arrived. I talk with astrophysicist Joseph Silk about the case for doing astronomy from the Moon, and what special challenges and opportunities are involved.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2023/07/17/243-joseph-silk-on-science-on-the-moon/Support Mindscape on Patreon.Joseph Silk received his Ph.D. in Astronomy from Harvard University.

Complexity scientists have been able to make an impressive amount of progress despite the fact that there is not universal agreement about what "complexity" actually is. We know it when we see it, perhaps, but there are a number of aspects to the phenomenon, and different researchers will naturally focus on their favorites. Today's guest, David Krakauer, is president of the Santa Fe Institute and a longtime researcher in complexity. He points the finger at the concept of agency. A ball rolling down a hill just mindlessly obeys equations of motion, but a complex system gathers information and uses it to adapt. We talk about what that means and how to think about the current state of complexity science.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2023/07/10/242-david-krakauer-on-complexity-agency-and-information/Support Mindscape on Patreon.David Krakauer received his D.Phil. in evolutionary biology from Oxford University.

Last year's Nobel Prize for experimental tests of Bell's Theorem was the first Nobel in the foundations of quantum mechanics since Max Born in 1954. Quantum foundations is enjoying a bit of a resurgence, inspired in part by improving quantum technology but also by a realization that understanding quantum mechanics might help with other problems in physics (and be important in its own right). Tim Maudlin is a leading philosopher of physics and also a skeptic of the Everett interpretation. We discuss the logic behind hidden-variable approaches such as Bohmian mechanics, and also the broader question of the importance of the foundations of physics.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2023/06/26/241-tim-maudlin-on-locality-hidden-variables-and-quantum-foundations/Tim Maudlin received his Ph.D. in philosophy from the University of Pittsburgh.
