Abstract: The importance of non-relativistic systems in physics cannot be overstated. Although the universe we live in is relativistic, at sufficiently low 'day to day' energy scales, it is governed by non-relativistic laws. Non-relativistic (or more precisely Galilean) physics has been a topic of interest for centuries, and its implications have been well studied and tested. But in last century there has been an exponential increase in our understanding of relativistic phenomenon. Hence it is important to ask if these new exotic relativistic phenomenon (like anomalies) leave any signature on the Galilean physics. In this talk we will explore a systematic mechanism to translate relativistic theories to Galilean, hence allowing us to study the effect of various relativistic phenomenon on Galilean systems, paying special attention to Galilean fluids. Rather than the usual 'low velocity limit' this approach is based on 'null reduction' which maps a relativistic theory to a Galilean theory in one lower dimension. The talk is based on recent papers: arXiv:1405.5687, 1505.05677, 1509.04718, 1509.05777.
