That perspective suggests a natural generalization: what if we also localize other aspects of inertial structure\, like rotation and scale\, and make them depend on matter dynamically? The resultant theory is uniquely determined up to an overall constant with the dimensions of velocity. It fails to be Galilean covariant\; investigating this failure allows one to 'bootstrap' up to (local) Lorentz covariance in a manner closely analogous to the bootstrap from magnetostatics to Maxwell's theory and special relativity. The resultant theory is equivalent to the first post-Newtonian approximation to general relativity.</p>\n<p>This talk will also be available live streamed on:</p>\n<p>Zoom at&nbsp\;</p>\n<p>YouTube at <a data-cke-saved-href="https://www.youtube.com/channel/UCrRp47ZMXD7NXO3a9Gyh2sg">https://www.youtube.com/channel/UCrRp47ZMXD7NXO3a9Gyh2sg</a>.</p>
