a unique paradigm for exploring strongly interacting Fermi systems in
nature. This ultracold atomic gas
offers unprecedented opportunities to test theoretical techniques that cross
interdisciplinary boundaries. A
bias magnetic field is used to tune the gas to a Feshbach resonance, where the
s-wave scattering length diverges, so that the interparticle spacing and
thermal de Broglie wavelength set the only length scales, making the system
universal. Even though it is
dilute, an atomic Fermi gas near a Feshbach resonance is the most strongly
interacting nonrelativistic system known, enabling tests of recent theories in
disciplines from high temperature superconductors to nuclear matter. I will describe our recent measurements
of universal viscosity in a resonantly interacting Fermi gas and compare the
ratio of the shear viscosity to the entropy density to that of a perfect fluid.</span></font></p><p class="MsoNormal" style="border:none;mso-border-alt:double windowtext 1.5pt;
