45 | Leonard Susskind on Quantum Information, Quantum Gravity, and Holography

For decades now physicists have been struggling to reconcile two great ideas from a century ago: general relativity and quantum mechanics. We don’t yet know the final answer, but the journey has taken us to some amazing places. A leader in this quest has been Leonard Susskind, who has helped illuminate some of the most mind-blowing ideas in quantum gravity: the holographic principle, the string theory landscape, black-hole complementarity, and others. He has also become celebrated as a writer, speaker, and expositor of mind-blowing ideas. We talk about black holes, quantum mechanics, and the most exciting new directions in quantum gravity. Support Mindscape on Patreon or Paypal. Leonard Susskind received his Ph.D. in physics from Cornell University. He is currently the Felix Bloch Professor of Physics at Stanford University. He has made important contributions to numerous ideas in theoretical physics, including string theory, lattice gauge theory, dynamical symmetry breaking, the holographic principle, black hole complementarity, matrix theory, the cosmological multiverse, and quantum information. He is the author of several books, including a series of pedagogical physics texts called The Theoretical Minimum. Among his numerous awards are the J.J. Sakurai Prize and the Oskar Klein Medal.

12 | Wynton Marsalis on Jazz, Time, and America

12 | Wynton Marsalis on Jazz, Time, and America

Jazz occupies a special place in the American cultural landscape. It's played in elegant concert halls and run-down bars, and can feature esoteric harmonic experimentation or good old-fashioned foot-stomping swing. Nobody embodies the scope of modern jazz better than Wynton Marsalis. As a trumpet player, bandleader, composer, educator, and ambassador for the music, he has worked tirelessly to keep jazz vibrant and alive. In this bouncy conversation, we talk about various kinds of music, how they might relate to physics, and some of the greater challenges facing the United States today. (This and the next few podcasts were recorded on the road with headset microphones, and the sound quality isn't quite as good, sorry about that.) Hailing from an accomplished New Orleans family, Wynton Marsalis was marked as a prodigy from a young age. He played locally before moving to New York and attend Julliard, and played and recorded with artists such as Art Blakey and Herbie Hancock. He has recorded numerous albums as a leader of small ensembles, big bands, and as a soloist with symphony orchestras. He is a multiple-time Grammy winner and the first to win in both jazz and classical categories in the same year, and in 1997 his oratorio Blood on the Fields was the first non-classical work to win the Pulitzer Prize for music. Marsalis founded and continues to lead Jazz at Lincoln Center, which is in residence at Lincoln Center along with such organizations as the New York Philharmonic, the Metropolitan Opera, and the New York City Ballet. He has won the National Medal of the Arts and the National Humanities Medal, along with numerous other awards and honorary degrees.

11 | Mike Brown on Killing Pluto and Replacing It with Planet 9

11 | Mike Brown on Killing Pluto and Replacing It with Planet 9

Few events in recent astronomical history have had the worldwide emotional resonance as the 2006 announcement that Pluto was no longer considered a planet, at least as far as the International Astronomical Union was concerned. The decision was a long time coming, but no person deserves more credit/blame for forcing the astronomical community's hand than Caltech astronomer Michael Brown. He and his team discovered a number of objects in the outer Solar System -- Eris, Haumea, Sedna, and others -- any of which was just as deserving of planetary status as Pluto. Rather than letting the planetary family proliferate without bound, astronomers decided that none of these objects dominated the orbits in which they moved, so none of them should be planets. Now Brown and his colleague Konstantin Batygin have found indirect evidence that there is another real planet far beyond Pluto's orbit -- which they have dubbed Planet Nine just to remind you that there are currently only eight.

Berkeley in 1994, and is currently the Richard and Barbara Rosenberg Professor of Planetary Astronomy at Caltech.

10 | Megan Rosenbloom on the Death Positive Movement

We're all going to die. But while we are alive, it's up to us how we understand and deal with that fact. In the United States especially, there is a tendency to not face up to the reality of death, and to assume that our goal should be to struggle at all costs to squeeze every last minute out of life. The Death Positive movement aims to change that, helping people to both face up to death on a personal and cultural level, and to give themselves more control over the manner of their own deaths. One of the leaders in this movement is today's guest, Megan Rosenbloom, who works as a medical librarian by day. We talk about attitudes toward death around the world, the differences between dying at home and in a hospital, the importance of autonomy in old age, and how individuals and societies can cope with the ultimate inevitability that comes with being alive.

9 | Solo -- Why Is There Something Rather than Nothing?

It's fun to be in the exciting, chaotic, youthful days of the podcast, when anything goes and experimentation is the order of the day. So today's show is something different: a solo effort, featuring just me talking without any guests to cramp my style. This won't be the usual format, but I suspect it will happen from time to time. Feel free to chime in below on how often you think alternative formats should be part of the mix. The topic today is "Why Is There Something Rather than Nothing?", or equivalently "Why Does the Universe Exist at All?" Heady stuff, but we're not going to back away from the challenge. What I have to say will roughly follow my recent paper on the subject, although in a more chatty and accessible style. It concerns ideas at the intersection of physics, philosophy, and theology, so tune in if you're into that sort of thing.

8 | Carl Zimmer on Heredity, DNA, and Editing Genes

8 | Carl Zimmer on Heredity, DNA, and Editing Genes

Our understanding of heredity and genetics is improving at blinding speed. It was only in the year 2000 that scientists obtained the first rough map of the human genome: 3 billion base pairs of DNA with about 20,000 functional genes. Today, you can send a bit of your DNA to companies such as 23andMe and get a report on your personal genome (ancestry, health risks) for about $200. Technologies like CRISPR are allowing scientists to edit genes, not just map them. Science writer Carl Zimmer has been following these advances for years, and has recently written a comprehensive book about heredity: She Has Her Mother's Laugh: The Powers, Perversions, and Potential of Heredity. We talk about how our understanding of heredity has changed over the years, how there is much more to inheritance than simply listing all the information we pass down in our DNA, and what the future might hold in a world where genetic manipulation becomes widespread.

7 | Yascha Mounk on Threats to Liberal Democracy

7 | Yascha Mounk on Threats to Liberal Democracy

Both words in the phrase "liberal democracy" carry meaning, and both concepts are under attack around the world. "Democracy" means that they people rule, while "liberal" (in this sense) means that the rights of individuals are protected, even if they're not part of the majority. Recent years have seen the rise of an authoritarian/populist political movement in many Western democracies, one that scapegoats minorities in the name of the true "will of the people." Yascha Mounk is someone who has been outspoken from the start about the dangers posed by this movement, and what those of us who support the ideals of liberal democracy can do about it. Among other things, we discuss how likely it is that liberal democracy could ultimately fail even in as stable a country as the United States. Yascha Mounk received his Ph.D. in Government from Harvard University. He is a Lecturer on Government at Harvard, a Senior Fellow in the Political Reform Program at New America, and Executive Director at the Tony Blair Institute for Global Change. His most recent book is The People vs. Democracy: Why Our Freedom Is in Danger and How to Save It.

6 | Liv Boeree on Poker, Aliens, and Thinking in Probabilities

Poker, like life, is a game of incomplete information. To do well in such a game, we have to think in terms of probabilities, unpredictable strategies, and Bayesian inference. These are ideas that play a central role in physics and rationality as well as in poker, which makes Liv Boeree such a great person to talk about them. Liv is a professional poker player who studied physics as a university student, and maintains an active interest in science generally and astrophysics in particular. We talk about poker, probability, the likelihood that aliens exist elsewhere in the universe, and how to be rational when it comes to charitable giving.

5 | Geoffrey West on Networks, Scaling, and the Pace of Life

5 | Geoffrey West on Networks, Scaling, and the Pace of Life

If you scale up an animal to twice its height, keeping everything else proportionate, its volume and weight become eight times as much. Such a scaling relation was used by J.B.S. Haldane in his famous essay, "On Being the Right Size," to help explain certain features of living organisms. But scaling relations go much deeper than that, and they are often much more subtle than the volume going as the cube of the length. Geoffrey West is a particle physicist turned complexity theorist, who studies how features from metabolism to lifespan change as we adjust the size of an organism -- or of other complex systems, from cities to computer networks. His insights have important implications for innovation, sustainability, and the best ways to organize life here on Earth.
