Encore - Brian Greene on String Theory

Our guest today is Mary Roach, a science writer who’s often drawn to taboo, or simply squeamish subjects, like sex, cadavers, or the digestive process. In books like Stiff, Bonk, Gulp, and Packing For Mars, Roach teaches her readers about the human body as well as basic – and not so basic – scientific concepts. It’s science through storytelling – and humor. On July 28, 2025. Roach came to KQED’s studios in San Francisco to talk about her new book, Replaceable You: Adventures in Human Anatomy, with journalist Alexis Madrigal, the co-host of KQED’s Forum.

We’re going back into the archives for a conversation with theoretical physicist Brian Greene, recorded in 2017. Greene is widely recognized for his groundbreaking discoveries in the field of super string theory, and he’s a rarity in the scientific world – famous outside of academia, thanks to his ability to make some of physics’ most complex concepts — including Quantum Mechanics and supersymmetry — understandable to non-scientists. His best-selling books include “The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos” and “The Elegant Universe.”  On February 23, 2017, Greene came to the Sydney Goldstein Theater to talk to Alexis Madrigal, a journalist and author who’s now co-host of KQED’s Forum.

Her new book, A Book of Days, is an intimate view into Smith’s life, particularly as it played out during the pandemic, and it features over 365 of her own photographs. The brilliantly idiosyncratic visual book features a year’s worth of images and reflections that chart Smith’s singular aesthetic—inspired by her wildly popular Instagram.
