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 Or is it a relic of an outdated, pre-empirical way of thinking about the world?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.

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.We're experimenting with a new benefit for Patreon supporters: short video (or audio-only) reflections by me on the podcast that just happened.

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.

It's somewhat amazing that cosmology, the study of the universe as a whole, can make any progress at all. But it has, especially so in recent decades. Partly that's because nature has been kind to us in some ways: the universe is quite a simple place on large scales and at early times. Another reason is a leap forward in the data we have collected, and in the growing use of a powerful tool: computer simulations. I talk with cosmologist Andrew Pontzen on what we know about the universe, and how simulations have helped us figure it out. We also touch on hot topics in cosmology (early galaxies discovered by JWST) as well as philosophical issues (are simulations data or theory?).Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2023/06/19/240-andrew-pontz…and-the-universe/Andrew Pontzen received his Ph.D. in astronomy from the University of Cambridge.

There is an image, especially in Western cultures, of the rugged, authentic, self-made individual choosing how to navigate the intricacies of the social world. But there is no mystical soul within us, manifesting as the immutable essence of self. What we think of as our "self" is shaped by our environment and our genes, and most of all by our interactions with other people. Psychologist Brian Lowery argues for a strong version of this thesis, positing that our sense of self is largely a social construct. We talk about the implications of this idea, and what it means for shifting notions of personal identity.Post with transcript: https://www.preposterousuniverse.com/podcast/2023/06/12/239-brian-lowery-on-the-social-self/Support Mindscape on Patreon.Brian Lowery received his Ph.D. in psychology from the University of California Los Angeles.

Modern computers are somewhat more secure against being hacked - either by an inanimate virus or a human interloper - than they used to be. But as our lives are increasingly intertwined with computers, the dangers that hacking poses are enormously greater. Why don't we just build unhackable computers? Scott Shapiro, who is a law professor and philosopher, explains why that's essentially impossible. On a philosophical level, computers rely on an essential equivalence between "data" and "code," which is vulnerable to exploitation. And on a psychological level, human beings will always be the weakest link in the chain of security.Web page with transcript: https://www.preposterousuniverse.com/podcast/2023/05/29/238-scott-shapiro-on-the-technology-and-philosophy-of-hacking/Support Mindscape on Patreon.Scott Shapiro received a J.D. from Yale Law School and a Ph.D. in philosophy from Columbia.

The modern world is large and interconnected, and there are a lot of systems that might be important to how it functions but about which most people are barely aware. One of these is the offshore wealth management network, which wealthy individuals can use both legitimately (to invest and plan their money) and less legitimately (to avoid taxation or hide questionable practices generally). Brooke Harrington is a sociologist who has studied offshore wealth management, including by training to be one. In a recent paper, she and colleagues analyze networks of offshore wealth managers as a complex system, uncovering power-law behavior and interesting nation-dependent network structures.Web site with transcript: https://www.preposterousuniverse.com/podcast/2023/05/22/237-brooke-harrington-on-offshore-wealth-as-a-complex-system/Support Mindscape on Patreon.Brooke Harrington received her Ph.D. in sociology from Harvard University.
