We have used Bragg spectroscopy to make precise measurements of a number of properties of a strongly interacting Fermi gas. These include the dynamic spin and density response functions, the static structure factors and Tan's universal contact parameter. We also present a technique for obtaining the homogeneous response functions and contact using measurements on a trapped (inhomogeneous) system.
