310 | Marc Kamionkowski on Dark Energy and Cosmic Anomalies
Cosmologists were, let us be honest, pretty stunned in 1998 when observations revealed that the universe is accelerating. There was an obvious plausible explanation, the cosmological constant proposed by Einstein, which is equivalent to a constant vacuum energy pervading space. But the cosmological constant was known to be enormously smaller than its "natural" value, and it seems fine-tuned for it to be so small but not yet zero. Once burned, twice shy, and since then we have been looking for evidence that the dark energy might not be strictly constant, even though that's even more fine-tuned. We talk to cosmologist Marc Kamionkowski about recent evidence that dark energy might be changing with time, and what this might have to do with the Hubble tension and other cosmic anomalies.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2025/03/31/310-marc-kamionkowski-on-dark-energy-and-cosmic-anomalies/Support Mindscape on Patreon.Marc Kamionkowski received his Ph.D. in physics from the University of Chicago.

309 | Christof Koch on Consciousness and Integrated Information
Consciousness is easier to possess than to define. One thing we can do is to look into the brain and see what lights up when conscious awareness is taking place. A complete understanding of this would be known as the "neural correlates of consciousness." Once we have that, we could hopefully make progress on developing a theoretical picture of what consciousness is and why it happens. Today's guest, Christof Koch, is a leader in the search for neural correlates and an advocate of a particular approach to consciousness, Integrated Information Theory.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2025/03/24/309-christof-koch-on-consciousness-and-integrated-information/Support Mindscape on Patreon.Christof Koch was awarded a Ph.D. from the Max Planck Institute for Biological Cybernetics.

308 | Alison Gopnik on Children, AI, and Modes of Thinking
We often study cognition in other species, in part to learn about modes of thinking that are different from our own. Today's guest, psychologist/philosopher Alison Gopnik, argues that we needn't look that far: human children aren't simply undeveloped adults, they have a way of thinking that is importantly distinct from that of grownups. Children are explorers with ever-expanding neural connections; adults are exploiters who (they think) know how the world works. These studies have important implications for the training and use of artificial intelligence.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2025/03/17/308-alison-gopnik-on-children-ai-and-modes-of-thinking/Support Mindscape on Patreon.Alison Gopnik received her D.Phil in experimental psychology from Oxford University. She is currently a professor of psychology and affiliate professor of philosophy at the University of California, Berkeley.

She is a past President of the Association for Psychological Science.

AMA | March 2025
Welcome to the March 2025 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!Link to the 2012 Moving Naturalism Forward workshop, mentioned in the episode.Blog post with questions and full transcript: https://www.preposterousuniverse.com/podcast/2025/03/10/ama-march-2025/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.

307 | Kevin Peterson on the Theory of Cocktails
A lot of science goes into crafting the perfect cocktail. Balancing sweet and bitter notes, providing the right amount of aeration and dilution, getting it to just the right temperature and keeping it that way. And even if you have no interest in cocktails as such, the general principles extend to other activities in art and in life. I talk to scientist-turned-mixologist Kevin Peterson about how to think about the simple magic of a perfect drink.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2025/03/03/307-kevin-peterson-on-the-theory-of-cocktails/Support Mindscape on Patreon.Kevin Peterson received a Ph.D. in Mechanical Engineering from the University of Michigan. He is currently co-owner of both Castalia (an experimental craft cocktail bar) and Sfumato Fragrances in Detroit, Michigan.
