It’s a well-worn cliché that oceans cover seventy percent of the surface of Earth, but we tend to give them secondary consideration when thinking about the environment. But climate change is wreaking havoc on the oceans, not to mention pollution and overfishing — 90% of the world’s marine fish stocks are fully exploited or depleted. Today’s guest, Sylvia Earle, is a well-known ocean scientist, a celebrated underwater explorer, and a tireless advocate for the world’s oceans. We talk about the current state of our oceans, what we know and have yet to learn about them, and what we can do individually and collectively to make things better.Support Mindscape on Patreon.Sylvia Earle received her Ph.D. in phycology from Duke University.

Science and storytelling have a long and tumultuous relationship. Scientists sometimes want stories to be just an advertisement for how awesome science is; storytellers sometimes want to use science for a few cheap thrills before abandoning it in the morning. But science is about ideas, and ideas can make for thrilling stories when done well. David Goyer is an accomplished screenwriter and director who has taken up a daunting task: adapting Isaac Asimov’s famous Foundation series for TV. (Available on Apple TV now.) We talk about the challenge of making a television version of a beloved series whose central character is a mathematician, and how science and storytelling relate to each other more generally.Support Mindscape on Patreon.David Goyer graduated from the University of Southern California’s School of Cinematic Arts. He has written stories or screenplays for a number of well-known films, including Dark City, Blade, the Dark Knight trilogy, Man of Steel, and Batman v Superman, as well as TV series such as FlashForward and Constantine.

As the holidays approach, we are being reminded of the fragility of the global supply chain. But at the same time, the supply chain itself is a truly impressive and fascinating structure, made as it is from multiple components that must work together in synchrony. From building an item in a factory and shipping it worldwide to transporting it locally, processing it in a distribution center, and finally delivering it to an address, the system is simultaneously awe-inspiring and deeply dehumanizing. I talk with Christopher Mims about how things are made, how they get to us, and what it all means for the present and future of our work and our lives.Support Mindscape on Patreon.Christopher Mims received a bachelor’s degree in neuroscience and behavioral biology from Emory University.

There is so much we don’t know about our universe. But our curiosity about the unknown shouldn’t blind us to the incredible progress we have made in cosmology over the last century. We know the universe is big, expanding, and accelerating. Modern cosmologists are using unprecedentedly precise datasets to uncover more details about the evolution and structure of galaxies and the distribution and nature of dark matter. Priya Natarajan is a cosmologist working at the interface of data, theory, and simulation. We talk about the state of modern cosmology, and how tools like gravitational lensing are providing us with detailed views of what’s happening in the distant universe.Support Mindscape on Patreon.Priya Natarajan received her Ph.D. in astrophysics from the University of Cambridge.

Games are everywhere, but why exactly do we play them? It seems counterintuitive, to artificially invent goals and obstacles just so we can struggle to achieve them. (And in some games, like Twister, the fun is in losing, even though you’re supposed to try to win.) C. Thi Nguyen is a philosopher who has developed a theory of games as an art form whose medium is agency. Within each game, we have defined goals, powers, and choices, and by playing different games we can experiment with different forms of agency. A dark side of this idea is to be found in “gamification” — turning ordinary-life activities into a game. Games give us clarity of values, and that clarity can be seductive but misleading, leading people to turn to conspiracy theories about the real world.Support Mindscape on Patreon.C.

Welcome to the October 2021 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). I take the large number of questions asked by Patreons, whittle them down to a more manageable size — 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!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.

Those of us who think that that the laws of physics underlying everyday life are completely known tend to also think that consciousness is an emergent phenomenon that must be compatible with those laws. To hold such a position in a principled way, it’s important to have a clear understanding of “emergence” and when it happens. Anil Seth is a leading researcher in the neuroscience of consciousness, who has also done foundational work (often in collaboration with Lionel Barnett) on what emergence means. We talk about information theory, entropy, and what they have to do with how things emerge.Support Mindscape on Patreon.Anil Seth received his D.Phil in Computer Science and Artificial Intelligence from the University of Sussex.

Traditional physics works within the “Laplacian paradigm”: you give me the state of the universe (or some closed system), some equations of motion, then I use those equations to evolve the system through time. Constructor theory proposes an alternative paradigm: to think of physical systems in terms of counterfactuals — the set of rules governing what can and cannot happen. Originally proposed by David Deutsch, constructor theory has been developed by today’s guest, Chiara Marletto, and others. It might shed new light on quantum gravity and fundamental physics, as well as having applications to higher-level processes of thermodynamics and biology.Support Mindscape on Patreon.Chiara Marletto received her DPhil in physics from the University of Oxford.

In the question to understand the biology of life, we are (so far) limited to what happened here on Earth. That includes the diversity of biological organisms today, but also its entire past history. Using modern genomic techniques, we can extrapolate backward to reconstruct the genomes of primitive organisms, both to learn about life’s early stages and to guide our ideas about life elsewhere. I talk with astrobiologist Betül Kaçar about paleogenomics and our prospects for finding (or creating!) life in the universe.Support Mindscape on Patreon.Betül Kaçar received her PhD in biomolecular chemistry from Emory University.

It's pretty clear that our genes affect, though they don't completely determine, who we grow up to be; children’s physical and mental characteristics are not completely unrelated to those of their parents. But this relationship has been widely abused throughout history to underwrite racist and sexist ideas. So there has been a counter-reaction in the direction of removing any consideration of genetic heritage from how we understand people. Kathryn Paige Harden argues in favor of a more nuanced view: DNA does matter, we can clearly measure some of its effects, and understanding those effects is a crucial tool in fighting discrimination and making the world a more equitable place.Support Mindscape on Patreon.Kathryn Paige Harden received her Ph.D. in psychology from the University of Virginia.
