Thank you for your clear headed, honest, not bound by the party line comments."Objects like electrons"? What does that mean? Exactly what kind of an "object" is an electron?

Does the existence of a "single formalism" (or mathematical description) imply that we really understand what is going on here? Do we yet understand what exactly the "wavefunction" is (if it is anything physical at all....)?

Really?

So we can completely explain quantum effects now on a qualitative basis? When did that occur?

Yeah...but aren't these predictions kind of ad hoc equations?

Can one derive the equations of matrix mechanics or Schroedinger's equation from first principles?
