That Robin Wilson, he doesn't half go on.
To infinity in fact, the topic of Robin's eighteenth and final talk on the equations that made mathematics. With an irritating little paradox to whet your appetite below and the full talk here.

I am going to talk on a work aimed at formalising approximation procedures in physics. The main new model-theoretic tool in this work is the notion of the ultraproduct in the classes of emerging metric structures which generalises the ultraproduct of general structures developed by J.Kiesler. In particular, the structure of Minkowski spacetime with the action of the Lorentz group is an emerging metric ultraproduct of certain finite structures invariant under the action of appropriate finite groups. Also, it is shown that any compact simple Lie group is representable as emerging metric ultraproduct of finite groups.
