 Conserved quantities are those quantities, such as energy, momentum, mass, or charge, that are conserved according to our physical theories. By deriving its inspiration from physics, where conservation laws play a central role, conserved quantity accounts promise to be able to meet the neo-Machian and neo-Russellian challenges. In fact, since, according to Noether’s First Theorem, there is a conservation law associated with each continuous symmetry property of a system, there seems to be a clear formal route for locating causal claims within physics.
