Abstract: Scale and conformal invariance plays an important role in field theory and statistical physics. In this talk, we describe a nonrelativistic version of scale invariance and conformal invariance. We review the history of the system called "fermions at unitarity" and show how its thermodynamic and kinetic properties are constrained by scale and conformal invariance. We also show how scale invariance appears at a very different energy scale in the behavior of nuclear reactions involving several neutrons in the final state.
