I was wondering if there is a difference between "formalism" and "formulation" when we say things like:
this is the mathematical formalism of quantum mechanics.
and we have also
Mathematical formulation of quantum mechanics.
All the same, Gleason’s approach assumes some key aspects of the mathematical formalism needed to connect quantum states to specific measurement outcomes.
this is a mathematical formulation of hamiltonian mechanics.
the Lagrangian formalism of mechanics.
I know the philosophical type of "formalism" but I dont think it would apply here.
I don't know if this question fits here in this forum or not so if not, let me know.
