>>11128604Lol @ applying cat theory in Siemens. It was probably something like that article posted recently where someone used eigenvalues, a "method from quantum mechanics", to analyse data.
I respect Baez but that article is useless. The idea of morphisms is not central to cat theory, if anything it is the idea of a functor that makes everything tick because you can just hop from a manifold to homologies, for instance.
