Janna Levin: The Unreasonable Effectiveness of the Klein Bottle
Theories of Everything with Curt Jaimungal

No other podcast has this: https://economist.com/TOE Janna Levin — Claire Tow Professor of Physics and Astronomy at Barnard College, founding Director of Sciences at Pioneer Works, and co-host of Quanta's The Joy of Why — is one of those guests who makes you feel the universe is stranger than you feared. Working with Brian Greene, she's exploring whether the shape of hidden dimensions, specifically a Klein bottle, could explain why matter won the war against antimatter after the Big Bang — no fudged parameters required. The geometry does the work. The universe's lopsidedness isn't a mystery to be plugged in; it's a consequence of the space we're sewn into.
