In order to understand the behavior of a system with many degrees of freedom, in physics or otherwise, some selective inattention is necessary. A description of interesting, big-picture, long-wavelength phenomena requires us to average over what the microscopic, fast-moving constituents are doing.
This coarse-graining procedure is almost always hard to do in practice. In the last decade, an amazing relation between many-body systems and gravity in extra dimensions (called holographic duality) was discovered using string theory. When it can be applied, holographic duality does the coarse-graining for us.
I will conclude with a discussion of recent attempts to say something about interesting states of matter using holographic duality.
