Description
I will discuss how the notion of dynamical frames helps in the construction (and interpretation) of diffeomorphism-invariant observables, encompassing and unifying the relational and dressed observables approaches. This also extends the concept of general covariance to a relational (and thus arguably more physical) form, associated with the covariance of gauge-invariant descriptions of physical laws under changes of dynamical frame.
