How important is experience in QM?

    How important is practical experience with quantum mechanics for understanding, as best as one can, the subject?

    For example: Weinberg in his QFT tome, briefly discusses QFT three point interactions in terms of angular momentum states. So, he points out that the interaction can be formulated with 3-j symbols. How would you do Born approx. for pion-nucleon scattering in the angular momentum rep .

    Or compute the numerical value(s) for the 1p-1s transition for the hydrogen atom, with the Coulomb gauge and non-rel QED.

    Does a separable potential in non-rel many-body theory imply and energy gap?

    Just curious.
