1.) Ladder operators are very well defined as L+/- = LX (+/-) iLY.

But what is its significance and from where it found its origination.

2.) Condition for any operator being HERMITIAN, plz don’t give mathematical response of this i.e. adjoint(operator) = operator, i know that. Please tell me in sense of physically , by giving example if possible.
