Default A Wikiid path.

Following up on a question, I asked "what is a Field in physics" in Wikipedia:
Field (physics) ->Gravitoelectromagnetism->Gravitational wave->Einstein field equations->Mathematics of general relativity->Cartan–Karlhede algorithm->Riemannian manifold->"Usually a Riemannian manifold is defined as a smooth manifold with a smooth section of the positive-definite quadratic forms on the tangent bundle."

I'm still not satisfied with the concept of a field as presented but it was interesting to wind up in a mathematical venue that I had seen before.
