Abstract: In this talk, I will briefly discuss how Corollaries V and VI to the laws of motion in Newton's Principia can be thought of as defining EFTs from which we can recover Newton's laws using the coset construction. This is, in effect, reverse-engineering Newton's laws from the symmetry-breaking principles that result from them. I will conclude with some lessons from this about scientific understanding and how to think about what a physical theory is.
