Homework Help: Hermitian operator

    1. The problem statement, all variables and given/known data

    Using Dirac notation (bra, kets), define the meaning of the term "Hermitian".

    2. Relevant equations



    3. The attempt at a solution

    From what I understand, a hermitian operator is simply one that has the same effect as its hermitian adjoint. So, I'm assuming it should simply be,

    [itex]
    <\psi|\hat{Q}|\psi>=<\psi|\hat{Q}^*|\psi>
    [/itex]

    I've seen it written in more complicating ways, so I'm guessing there's a little more to it. Please help.
