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.

46 | Kate Darling on Our Connections with Robots

Most of us have no trouble telling the difference between a robot and a living, feeling organism. Nevertheless, our brains often treat robots as if they were alive. We give them names, imagine that th...

44 | Antonio Damasio on Feelings, Thoughts, and the Evolution of Humanity

When we talk about the mind, we are constantly talking about consciousness and cognition. Antonio Damasio wants us to talk about our feelings. But it's not in an effort to be more touchy-feely; Damasi...
