Theoretical "mastery" is achievable, for a fact.
Or smthg. On "minimal" principles instead.
E.g. "How" a weak solution to any "classical" PDE can "quite purely" be logically derived, the same as all of those "mysterious" Noether Theorems, the same as all those questions directed at "symmetry" itself are.
Invite people and block bs, this simple it is, in fact
