349 | Daniel Harlow on What Quantum Gravity Teaches Us About Quantum Mechanics

There is something special about gravity. After decades of effort, there is still no convergence on the right way to reconcile Einstein's theory of general relativity with the framework of quantum mechanics. But a number of intriguing ideas have arisen along the way, including black hole radiation, the wave function of the universe, the AdS/CFT correspondence, and the role of quantum information theory. Theoretical physicist Daniel Harlow has made significant contributions to our understanding of information loss in black holes; in this conversation we turn those insights onto quantum cosmology, with potentially significant implications for how quantum mechanics itself works.

Daniel Harlow received his Ph.D. in physics from Stanford University. He is currently an associate professor of physics at the Massachusetts Institute of Technology. Among his awards are a Packard Fellowship and the New Horizons in Physics Prize.

Like any machine, bodies occasionally break down, and it's natural to go in search of a replacement part. Ancient societies featured simple prosthetics for teeth, noses, and limbs, while modern medici...
