One of the great mysteries about strongly correlated materials is that their transport properties seem to be universal. For instance, a linear resistivity is ubiquitious to many materials whose microscopic physics and scattering mechanisms can vary immensely. In this talk I will discuss how universality can arise in the diffusion constants of holographic theories. In particular I will show that in many holographic theories diffusion is universally related to the so-called `butterfly effect’. This work suggests a potential new connection between transport at strong coupling and the field of quantum chaos.
