I meant actual fundamental physics, not the standard model, which is already known to be a (very good) approximation. There are some statements we can make which at least have the possibility of being exactly correct—the general form of the Schrodinger equation, General Relativity, conservation of momentum… that sort of thing.
As for truncated series etc, that fits exactly into the sort of approximation I was talking about.
