# Footprints of the Nearly Perfect Liquid - Nuclear Experiment

Abstract: In relativistic heavy-ion collisions, the system has gone through a series ofevolution, almost at every stage of its evolution it leaves behind footprintsin flow observable. Those footprints contain valuable information of the bulkproperty of the nearly perfect liquid. By examing footprints of the nearlyperfect liquid, we address a few important issues, including the idealhydrodynamic limit, estimation of $\eta-s$, testing the Number of ConstituentQuark scaling at low energy, in small system, at large transverse momentum, andin forward region. Future prospect of flow study is discussed.
