222 | Andrew Strominger on Quantum Gravity and the Real World

Quantum gravity research is inspired by experiment — all of the experimental data that supports quantum mechanics, and supports general relativity — but it's only inspiration, not detailed guidance. So it's easy to "do research on quantum gravity" and get lost in a world of toy models and mathematical abstraction. Today's guest, Andrew Strominger, is a leading researcher in string theory and quantum gravity, and one who has always kept his eyes on the prize: connecting to the real world. We talk about the development of string theory, the puzzle of a positive cosmological constant, and how black holes and string theory can teach us about each other.

Andrew Strominger received his Ph.D. in physics from the Massachusetts Institute of Technology. He is currently the Gwill E. York Professor of Physics at Harvard University. Among his awards are the Dirac Medal, the Klein Medal, the Breakthrough Prize in Fundamental Physics, and a Guggenheim Fellowship.

156 | Catherine D'Ignazio on Data, Objectivity, and Bias

How can data be biased? Isn't it supposed to be an objective reflection of the real world? We all know that these are somewhat naive rhetorical questions, since data can easily inherit bias from the p...

155 | Stephen Wolfram on Computation, Hypergraphs, and Fundamental Physics

It's not easy, figuring out the fundamental laws of physics. It's even harder when your chosen methodology is to essentially start from scratch, positing a simple underlying system and a simple set of...

153 | John Preskill on Quantum Computers and What They're Good For

Depending on who you listen to, quantum computers are either the biggest technological change coming down the road or just another overhyped bubble. Today we're talking with a good person to listen to...

152 | Charis Kubrin on Criminology, Incarceration, and Hip-Hop

It's all well and good to talk abstractly about morality and justice, but at some point you have to sit down and figure out what to do about people who break the rules. In our modern legal system, mos...

Any system in which politicians represent geographical districts with boundaries chosen by the politicians themselves is vulnerable to gerrymandering: carving up districts to increase the amount of se...
