265 | John Skrentny on How the Economy Mistreats STEM Workers
Universities and their students are constantly being encouraged to produce more graduates majoring in STEM fields -- science, technology, engineering, and mathematics. That's the kind of training that will get you a rewarding job, students are told, while at the policy level it is emphasized how STEM workers are needed to drive innovation and growth. In his new book Wasted Education, sociologist John Skrentny points out that the post-graduation trajectories of STEM graduates are more likely to involve being chewed up and spit out by the tech economy than to end up with stable long-term careers. We talk about why that's the case and what might be done about it.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/02/05/265-john-skrentny-on-how-the-economy-mistreats-stem-workers/Support Mindscape on Patreon.John Skrentny received his Ph.D. in sociology from Harvard University.

264 | Sabine Stanley on What's Inside Planets
The radius of the Earth is over 6,000 kilometers, but the deepest we've ever dug below the surface is only about 12 km. Yet we have a quite reliable idea of the structure of the Earth's interior -- inner core, outer core, mantle, crust -- not to mention pretty good pictures of what's going on inside some other planets. How do we know those things, and what new things are we learning in the exoplanet era? I talk with astrophysicist and planetary scientist Sabine Stanley about how we use gravitation, seismology, magnetic fields, and other tools to learn what's happening inside planets.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/01/29/264-sabine-stanley-on-whats-inside-planets/Support Mindscape on Patreon.Sabine Stanley received a Ph.D. in geophysics from Harvard University.

263 | Chris Quigg on Symmetry and the Birth of the Standard Model
Einstein's theory of general relativity is distinguished by its singular simplicity and beauty. The Standard Model of Particle Physics, by contrast, is a bit of a mess. So many particles and interactions, each acting somewhat differently, with a bunch of seemingly random parameters. But lurking beneath the mess are a number of powerful and elegant ideas, many of them stemming from symmetries and how they are broken. I talk about some of these ideas with Chris Quigg, who with collaborator Robert Cahn has written a new book on the development of the Standard Model: Grace in All Simplicity.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/01/22/263-chris-quigg-on-symmetry-and-the-birth-of-the-standard-model/Support Mindscape on Patreon.Chris Quigg received his Ph.D. in physics from the University of California, Berkeley.

262 | Eric Schwitzgebel on the Weirdness of the World
Scientists and philosophers sometimes advocate pretty outrageous-sounding ideas about the fundamental nature of reality. (Arguably I have been guilty of this.) It shouldn't be surprising that reality, in regimes far away from our everyday experience, fails to conform to common sense. But it's also okay to maintain a bit of skepticism in the face of bizarre claims. Philosopher Eric Schwitzgebel wants us to face up to the weirdness of the world. He claims that there are no non-weird ways to explain some of the most important features of reality, from quantum mechanics to consciousness.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/01/15/262-eric-schwitzgebel-on-the-weirdness-of-the-world/Support Mindscape on Patreon.Eric Schwitzgebel received his Ph.D. in philosophy from the University of California, Berkeley.

261 | Sanjana Curtis on the Origins of the Elements
In mid-20th-century cosmology, there was a debate over the origin of the chemical elements. Some thought that they could be produced in the Big Bang, while others argued that they were made inside stars. The truth turns out to be a combination of both, with additional complications layered in. Some of the elements of the periodic table come all the way from the Big Bang, but others are made inside stars or in stellar explosions. But still others are made by cosmic rays or when neutron stars and black holes merge together. We talk to nuclear astrophysicist Sanjana Curtis about all the different ways that the universe is cleverly able to produce various elements.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/01/08/261-sanjana-curtis-on-the-origins-of-the-elements/Support Mindscape on Patreon.Sanjana Curtis received her Ph.D. in physics from North Carolina State University.

260 | Ricard Solé on the Space of Cognitions
Octopuses, artificial intelligence, and advanced alien civilizations: for many reasons, it's interesting to contemplate ways of thinking other than whatever it is we humans do. How should we think about the space of all possible cognitions? One aspect is simply the physics of the underlying substrate, the physical stuff that is actually doing the thinking. We are used to brains being solid -- squishy, perhaps, but consisting of units in an essentially fixed array. What about liquid brains, where the units can move around? Would an ant colony count? We talk with complexity theorist Ricard Solé about complexity, criticality, and cognition.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/01/01/260-ricard-sole-on-the-space-of-cognitions/Support Mindscape on Patreon.Ricard Solé received his Ph.D. in physics from the Polytechnic University of Catalonia.

The final Mindscape podcast of each year is devoted to a short, reflective Holiday Message. This year the theme is Immortality: whether it's an attractive idea, and whether the laws of physics and cosmology would allow for it in principle. (Spoiler: they do not.) Mindscape will return as usual on January 1, 2024.

259 | Adam Frank on What Aliens Might Be Like
It wasn't that long ago that topics like the nature of consciousness, or the foundations of quantum mechanics, or prospects for extraterrestrial life were considered fringey and disreputable by much of the scientific community. In all these cases, the tide of opinion is gradually changing. Life on other worlds, in particular, has seen a remarkable growth in interest -- how life could start on other worlds, how we can detect it in the solar system and on exoplanets, and even thoughts about advanced alien civilizations. I talk with astrophysicist Adam Frank about some of those thoughts. We also give the inside scoop on what professional scientists think about UFOs.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2023/12/11/259-adam-frank-on-what-aliens-might-be-like/Support Mindscape on Patreon.Adam Frank received a Ph.D. in physics from the University of Washington.
