Episode notes

Fractals are unambiguous decorations of chaotic behavior. In a lot of these systems, what you can look at is the possibility of large sets. So for instance, large numbers of orbits around black holes,. whether they merge or escape or are stable. And so what you can do is look at the fractal set of possibilities. But no matter how precise you try to make those definitions, you still find all possibilities.

It's a big universe out there, full of an astonishing variety of questions and puzzles. Today's guest, Janna Levin, is a physicist who has delved into some of the trippiest aspects of cosmology and gravitation: the topology of the universe, extra dimensions of space, and the appearance of chaos in orbits around black holes. At the same time, she has been a pioneer in talking about science in interesting and innovative ways: a personal memoir, a novelized narrative of famous scientific lives, and a journalistic exploration of one of the most important experiments of our time. We talk about how one shapes an unusual scientific career, and how the practice of science relates to more traditionally humanistic concerns. Support Mindscape on Patreon or Paypal. Janna Levin received a Ph.D. in physics from MIT, and is now the Tow Professor of physics and astronomy at Barnard College of Columbia University. She is the author of How the Universe Got Its Spots, A Madman Dreams of Turing Machines, and Black Hole Blues. Her awards include the PEN/Bingham Prize and a Guggenheim Fellowship. She is also the director of sciences at Pioneer Works in Brooklyn, NY.
