    I Integration of the Outer Product of a Basis

    Hello all. I'm using Griffiths' Introduction to Quantum Mechanics (3rd ed., 2018), and have come across what, on the face of it, seems a fairly straightforward principle, but which I cannot justify to myself. It is used, tacitly, in the first equation in the following worked example: The...

    Most likely location of a particle versus expected value of

    Yes, thanks both of you. I've just been having a slightly dull morning; I should know the difference between a mode and mean by now!

    Most likely location of a particle versus expected value of

    Hello. I'm using Griffiths' introductory textbook on quantum mechanics, which I have just begun, and have arrived at a question on a simple wave function: The answer to the first question I know to be √(3/b). The answer to part e is (2a + b) / 4. My problem is that I don't understand how...
