COMPLEXITY Complex Conceptions of Time with David Krakauer, Ted Chiang, David Wolpert, & James Gleick
Metaphors Shape How We Experience Time
- James Gleick says metaphors shape our concept of time.
- He argues metaphors make time feel like a spendable quantity you can save, waste, or bank.
Cultural Maps Flip Past And Future
- Ted Chiang highlights that some cultures invert past/future spatial metaphors.
- He uses the I'mara example to show our time metaphors are culturally bound, not universal.
Memory Is Statistical Retrodiction
- David Wolpert frames memories as statistical inferences about the past.
- He emphasizes records allow confident retrodiction while future prediction remains probabilistic and weaker.
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.
