Dear Marc,

I'm no physicist, so please correct me but IMHO:

Symmetries = relations
Forces - could they not be seen as certain invariances, thus also
relating to symmetries?

Fields - the aggregate of forces on all spacetime "points" - do not see
why this should not be mathematical relation?

Why not? Do you have a counterexample?

Günther
