Some people never drink wine; for others, it’s an indispensable part of an enjoyable meal. Whatever your personal feelings might be, wine seems to exhibit a degree of complexity and nuance that can be intimidating to the non-expert. Where does that complexity come from, and how can we best approach wine? To answer these questions, we talk to Matthew Luczy, sommelier and wine director at Mélisse, one of the top fine-dining restaurants in the Los Angeles area. Matthew insisted that we actually drink wine rather than just talking about it, so drink we do. Therefore, in a Mindscape first, I recruited a third party to join us and add her own impressions of the tasting: science writer Jennifer Ouellette, who I knew would be available because we’re married to each other. We talk about what makes different wines distinct, the effects of aging, and what’s the right bottle to have with pizza. You are free to drink along at home, with exactly these wines or some other choices, but I think the podcast will be enjoyable whether you do or not. Support Mindscape on Patreon or Paypal.

He is also active in photography and music. Mélisse home page Personal/photography page Instagram Ask a Somm: When Should I Decant Wine?

The space age officially began in 1957 with the launch of the Sputnik 1 satellite. But recent years have seen the beginning of a boom in the number of objects orbiting Earth, as satellite tracking and communications have assumed enormous importance in the modern world. This raises obvious concerns for the control and eventual fate of these orbiting artifacts. Natalya Bailey is pioneering a novel approach to satellite propulsion, building tiny ion engines at her company Accion Systems. We talk about how satellite technology is rapidly changing, and what that means for the future of space travel inside and outside the Solar System.             Support Mindscape on Patreon or Paypal. Natalya Bailey received her Ph.D. in aeronautics and astronautics from MIT, where she helped invent a new kind of ion engine. She is currently co-founder and chief executive officer of Accion Systems Inc. She has been included in 30 Under 30 lists from Forbes, Inc, and MIT Technology Review.

One of the most important insights in the history of science is the fact that complex behavior can arise from the undirected movements of small, simple systems. Despite the fact that we know this, we’re still working to truly understand it — to uncover the mechanisms by which, and conditions under which, complexity can emerge from simplicity. (Coincidentally, a new feature in Quanta on this precise topic came out while this episode was being edited.) Steven Strogatz is a leading researcher in this field, a pioneer both in the subject of synchronization and in that of small-world networks. He’s also an avid writer and wide-ranging thinker, so we also talk about problems with the way we educate young scientists, and the importance of calculus, the subject of his new book.             Support Mindscape on Patreon or Paypal. Steven Strogatz received his Ph.D. in applied mathematics from Harvard, and is currently the Jacob Gould Schurman Professor of Applied Mathematics at Cornell. His work has ranged over a wide variety of topics in mathematical biology, nonlinear dynamics, networks, and complex systems. He is the author of a number of books, including SYNC, The Joy of x, and most recently Infinite Powers. His awards include teaching prizes at MIT and Cornell, as well as major prizes from the Joint Policy Board for Mathematics, the American Association for the Advancement of Science, the Mathematical Association of America, and the Lewis Thomas Prize.

The modern world is full of technology, and also with anxiety about technology. We worry about robot uprisings and artificial intelligence taking over, and we contemplate what it would mean for a computer to be conscious or truly human. It should probably come as no surprise that these ideas aren’t new to modern society — they go way back, at least to the stories and mythologies of ancient Greece. Today’s guest, Adrienne Mayor, is a folklorist and historian of science, whose recent work has been on robots and artificial humans in ancient mythology. From the bronze warrior Talos to the evil fembot Pandora, mythology is rife with stories of artificial beings. It’s both fun and useful to think about our contemporary concerns in light of these ancient tales. Support Mindscape on Patreon or Paypal. Adrienne Mayor is a Research Scholar Classics and History and Philosophy of Science at Stanford University. She is also a Berggruen Fellow at Stanford’s Center for Advanced Study in the Behavioral Sciences. Her work has encompasses fossil traditions in classical antiquity and Native America, the origins of biological weapons, and the historical precursors of the stories of Amazon warriors. In 2009 she was a finalist for the National Book Award.

Consciousness has many aspects, from experience to wakefulness to self-awareness. One aspect is imagination: our minds can conjure up multiple hypothetical futures to help us decide which choices we should make. Where did that ability come from? Today’s guest, Malcolm MacIver, pinpoints an important transition in the evolution of consciousness to when fish first climbed on to land, and could suddenly see much farther, which in turn made it advantageous to plan further in advance. If this idea is true, it might help us understand some of the abilities and limitations of our cognitive capacities, with potentially important ramifications for our future as a species.            Support Mindscape on Patreon or Paypal. Malcolm MacIver received his Ph.D. in neuroscience in 2001 from the University of Illinois and the Beckman Institute of Advanced Science and Technology. (This was after an unconventional childhood where he dropped out of school at age 9 and later talked his way into a community college program.) He is currently a professor of Mechanical Engineering, Biomedical Engineering, and Neurobiology at Northwestern University.

Let’s say, for sake of argument, that you don’t believe in God or the supernatural. Is there still a place for talking about transcendence, the sacred, and meaning in life? Some of the above, but not all? Today’s guest, Alan Lightman, brings a unique perspective to these questions, as someone who has worked within both the sciences and the humanities at the highest level. In his most recent book, Searching for Stars on an Island in Maine, he makes the case that naturalists should take transcendence seriously. We talk about the assumptions underlying scientific practice, and the implications that the finitude of our lives has for our search for meaning. Support Mindscape on Patreon or Paypal. Alan Lightman received his Ph.D. in physics from the California Institute of Technology. After a number of years working as a theoretical astrophysicist specializing in black holes and high-energy processes, he scored an international bestseller with his novel Einstein’s Dreams. Increasingly concentrating on writing, he moved from Harvard to MIT, where he became the first professor to be jointly appointed in the sciences and the humanities. He later was made the John Burchard Professor of Humanities at MIT, which he has subsequently stepped down from to devote more time to writing. He is the recipient of numerous awards, including the Gemant Award from the American Institute of Physics. He is also the founder of the Harpswell Foundation, which supports young women leaders in Southeast Asia.

When many of us think “Ancient Rome,” we think of the Empire and the Caesars. But the Empire was preceded by the Roman Republic, which flourished for a full five centuries. Why, after such a long and prosperous run, would an essentially democratic form of government change — with a good deal of approval from its citizens — into an autocracy? That’s the question I discuss with today’s guest, historian Edward Watts. It’s a fascinating story with many contemporary resonances, especially how reformers choose to balance working within the system to overthrowing it entirely. Lessons for modern politics are left largely for listeners to draw for themselves. Support Mindscape on Patreon or Paypal. Edward Watts received his Ph.D. in history from Yale University. He is presently the Vassiliadis Professor of Byzantine Greek History at UC San Diego, where he was formerly Co-Director of the Center for Hellenistic Studies.

Quantum mechanics is our best theory of how reality works at a fundamental level, yet physicists still can’t agree on what the theory actually says. At the heart of the puzzle is the “measurement problem”: what actually happens when we observe a quantum system, and why do we apparently need separate rules when it happens? David Albert is one of the leading figures in the foundations of quantum mechanics today, and we discuss the measurement problem and why it’s so puzzling. Then we dive into the Many-Worlds version of quantum mechanics, which is my favorite (as I explain in my forthcoming book Something Deeply Hidden). It is not David’s favorite, so he presents the case as to why you should be skeptical of Many-Worlds. (The philosophically respectable case, that is, not a vague unease at all those other universes.) Support Mindscape on Patreon or Paypal. David Albert received his Ph.D. in physics from Rockefeller University. He is currently the Frederick E. Woodbridge Professor of Philosophy at Columbia University. His research involves a number of topics within the foundations of physics, including the arrow of time (coining the phrase “Past Hypothesis” for the low-entropy state of the early universe) and quantum mechanics. He is the author of a number of books, including Time and Chance, Quantum Mechanics and Experience, and After Physics.
