    "abstract": "Elliptic flow measurements at RHIC suggest that quark gluon plasma flows with\nvery little viscosity compared to weak coupling expectations, challenging\ntheorists to explain why this fluid is so nearly ``perfect\u0027\u0027. It is therefore\nvital to find quantitative experimental information on the viscosity of the\nplasma. We propose that measurements of transverse momentum fluctuations can be\nused to determine the shear viscosity. We use current data to estimate the\nviscosity-to-entropy ratio in the range from 0.08 to 0.3, and discuss how\nfuture measurements can reduce this uncertainty.",
