I first compute the drag and diffusion rates of heavy mesons in AdS_5.
Subsequently I show how thermal noise arises in the context of gauge gravity duality. I use this identification to recompute several results previously found in the diffusion of heavy quarks. However, I extend these results to compute the photon emission rate from a fast quark in AdS_5 and contrast this rate with perturbation theory. Finally I conclude by indicating how an appealing picture of thermal noise which arises can be used to calculate the diffusion of mesons whose mass is of order the temperature.
