    What are the Benefits of Using Quark Diagrams in Particle Physics?

    As an alternative to Feynman diagrams (?), or so I heard... It doesn't sound ok, right?

    Self-explaining question... Thanks.

    Choosing Between Engineering and Physics: Making the Right Career Move at 17

    I had EXACTLY the same dilemma, at the same age... I chose option A, but 2 years later I switched to Engineering Physics and found out this is, for an undergraduate degree, the field I feel most comfortable with. I think it gives me the chance to choose later the Aerospace or a more theoretical...

    Hermitian Operators and Eigenvalues

    Well, I think you can still get eigenvalues for non-hermitian operators. If you calculate the modulus of the eigenvalue and the eigenfunction (multiplying by its complex conjugate) you'll find you need the eigenvalue's modulus to be 1. So you can propose it to be exp(-i*alpha). It should make...

    Hermitian Operators and Eigenvalues

    I'm sorry, it's not hermitian. Got confused using bra-kets to prove it. C(psi)=(psi*) If it were hermitian then the integral (psi*)C(psi) would be equal to that of (psi)(C(psi*)), but substituting C(psi) in the integrals yields (psi*)(psi*) is equal to (psi)(psi). I guess it would be an...

    Hermitian Operators and Eigenvalues

    Homework Statement C is an operator that changes a function to its complex conjugate a) Determine whether C is hermitian or not b) Find the eigenvalues of C c) Determine if eigenfunctions form a complete set and have orthogonality. d) Why is the expected value of a squared hermitian...
