Sad news for all of us: producer Rachael Cusick— who brought us soul-stirring stories rethinking grief (https://zpr.io/GZ6xEvpzsbHU) and solitude (https://zpr.io/eT5tAX6JtYra), as well as colorful musings on airplane farts (https://zpr.io/CNpgUijZiuZ4) and belly flops (https://zpr.io/uZrEz27z63CB) and Blueberry Earths (https://zpr.io/EzxgtdTRGVzz)— is leaving the show. So we thought it perfect timing to sit down with her and revisit another brainchild of hers, The Cataclysm Sentence, a collection of advice for The End. To explain: one day in 1961, the famous physicist Richard Feynman stepped in front of a Caltech lecture hall and posed this question to a group of undergraduate students: “If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence was passed on to the next generation of creatures, what statement would contain the most information in the fewest words?” Now, Feynman had an answer to his own question—a good one. But his question got the entire team at Radiolab wondering, what did his sentence leave out? So we posed Feynman’s cataclysm question to some of our favorite writers, artists, historians, futurists—all kinds of great thinkers. We asked them “What’s the one sentence you would want to pass on to the next generation that would contain the most information in the fewest words?” What came back was an explosive collage of what it means to be alive right here and now, and what we want to say before we go.

And now for something completely different!  Last October, The Santa Fe Institute held its third InterPlanetary Festival at SITE Santa Fe, celebrating the immensely long time horizon, deep scientific and philosophical questions, psychological challenges, and engineering problems involved in humankind’s Great Work to extend its understanding and presence into outer space. For our third edition, we turned our attention to visionary projects living generations will likely not live to see completed — interstellar travel, off-world cities, radical new ways of understanding spacetime — as an invitation to engage in science as not merely interesting but deeply fun. For our first panel, we decided to inquire: What is time, really? How has science fiction changed  the way we track and measure, speak about, and live in time? And how do physics and complex systems science pose and answer these most fundamental questions?Welcome to COMPLEXITY, the official podcast of the Santa Fe Institute. I’m your host, Michael Garfield, and every other week we’ll bring you with us for far-ranging conversations with our worldwide network of rigorous researchers developing new frameworks to explain the deepest mysteries of the universe.In this week’s episode, we share the Complex Conceptions of Time panel from InterPlanetary Festival 2022, moderated by SFI President David Krakauer and featuring an all-star trinity of panelists: science journalist James Gleick, sci-fi author and SFI Miller Scholar Ted Chiang, and physicist and SFI Professor David Wolpert. In this hour, we play with and dissect some favorite metaphors for time, unroll the history of time’s mathematization, review time travel in science fiction, and examine the arguments between free will and determinism.Be sure to check out our extensive show notes with links to all our references at complexity.simplecast.com — as well as the extensive, interactive web-based “Voyager Golden Record Liner Notes” with links to not only all of the panels from IPFest 2022 but also copious additional resources, including contributor bios, peer-reviewed publications, science fiction and nonfiction science writing, and more…If you value our research and communication efforts, please subscribe, rate and review us at Apple Podcasts or Spotify, and consider making a donation — or finding other ways to engage with us — at santafe.edu/engage.If you’d like some HD virtual backgrounds of the SFI campus to use on video calls and a chance to win a signed copy of one of our books from the SFI Press, help us improve our science communication by completing a survey about our various scicomm channels.
