Well I mean Einsteins equations[1] of General Relativity are in some sense "simple". I imagine they mean "simple" in a similar sense, given that at least one of the previous "too simple" models[2] involves repeatedly solving a Laplace equation numerically to search for a valid solution. But yeah, certainly would be nice to include it when you got a title like that.
