Gauge/Gravity Duality

Description: 

Gauge theories, which describe the particle interactions, are well understood, while quantum gravity has many puzzles. Remarkably, in recent years we have learned that these are actually dual, the same system written in different variables.  On the one hand this provides our most precise description of quantum gravity, and resolves some long-standing paradoxes.  On the other, it gives a new perspective on the strong interaction; for example, some properties of heavy ion collisions are best modeled by black holes.  I describe these ideas, and discuss current and future directions.
