Agreed,
Your equations represent fundamental basic equations that must be mastered on the way to the author’s final list.
As basic elements, they are part of the foundation, and far more important, but not as extreme.
Navier-Stokes and the rest are sideshows, and in fact, Navier-Stokes is neither as important, as pervasive, nor as "extreme" as Laplace's Equation, which doesn't even appear.
May's Map is "extreme" -- under some bizarro world definition that has no meaning in science or mathematics -- but more importantly, it is completely inconsequential.
