The idea that our world may have hidden extra dimensions dates back to the 1920s, but so far has not become more than a theoretical curiosity.
More recently the paradigm of extra dimensions emerged in a different guise within the “holographic duality”. The ideas of holography gave a new perspective on a number of old questions in theoretical physics ranging from quark confinement in strong interactions, hydrodynamics of strongly-coupled plasmas to transport in the quantum critical regime. Holography relates these highly non-trivial questions to gravitational dynamics in curved space-time. The talk will review the basic ideas of holography and is intended for a general physics audience.
