Sean Carroll on Theoretical Physics and Interdisciplinarity

Ultimately, this episode is about science and scholarship. As Sean says,  “understanding something as well as you can in science means that you need to confront the data and be pushed out of your comfort zone.” I find it counterintuitive but true: this episode shows us that theoretical physics and indeed science pushes us into the subjunctive. It’s our job as scholars to think beyond  what’s given, beyond what’s happening right now around us, and think about what could happen, perhaps what would happen if certain constraints were lifted.

If we suffered a mass extinction, what would life look like? If the mouth were configured differently, how would phonetic change have been different from the beginning? What about the uniformitarian hypothesis? If a language dies out and a new hybrid language forms, what are the possibilities and impossibilities? And then what happens when we think about this space of possibilities combinatorially vs. probabilistically vs. normatively?

Among other things, Sean and I discuss the romance of the university, the merits of interdisciplinarity, his blog posts from 20+ years ago on Zizek, language, and metaphor—we inevitably touch on AI and writing—and, of course, we discuss what it means to host podcasts and present public scholarship.

Sean Carroll, the host of Sean Carroll's Mindscape, is the Homewood Professor of Natural Philosophy at Johns Hopkins University. He is the author of several books including The Biggest Ideas in the Universe: Space, Time, and Motion, and Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime.
