    this reminds me of the heatring problem that Fourier studied

    Matrices that represent the projectors

    Here is a home assignment, I don't want it to be solved, just help understand what the teacher is after in one specific part. I looked in the course litterature and searched the web and couldn't find anything relevant. calculate the eigenvalues and eigenvectors of a certain matrix which I...

    How Can Degenerate Perturbation Theory Help Identify Zero Order Eigenstates?

    thnx that helped alot. Let me see if I got this right: Eigenvalues are the observables and the eigenvectors are the states of the system. what would degenerate spectrum mean physically. thnx

    How Can Degenerate Perturbation Theory Help Identify Zero Order Eigenstates?

    I borrow this thread to ask a question that is similar to this one. What does it mean that an operator has a degenarate spectrum and how can we see that if the operator is represented by a matrix. Thanx a lot and I hope I'm not stepping on anybodys toe by using this thread.

    Physics Should I Leave Physics? Deciding Between a Career in Physics & Engineering

    the reason why I'm asking where u from is that I want to know if there is a difference between different countries. I for instance live in sweden and here the major companies first and foremost employes engineers rather then physicists.

    Knowing the frequency of light

    I was watching a movie talking about the hydrogen atom and the study of spectrum from hydrogen gas when a question poped into my head. How can we know the frequency of light from observing its colour? Please give example of experiments done to confirm that. Thank you all in advance

    Physics Should I Leave Physics? Deciding Between a Career in Physics & Engineering

    Don't missunderstand me, I love physics and don't have any doubts about it. I also love the good life, which I've missed out on for so long. Havings depts and counting coins is not something I can just wave away. So that's why I'm wandering if a physicist can have an interesting job at a company...

    Solving Potential of Line Charge: Square 6m on a Side

    I'm sorry I don't know the answer. I'm just wondering about the z-plane. what does that even mean. a palce has two axis

    How Are Quantum Numbers Derived from the Schrödinger Equation?

    let me see if I got this one right: By solving the S E for bound system u got the quantum number n l and ml. each set of numbers corresponds to a curtain wave function and electron. One gots fine structure when adding the spin up 1/2 and down 1/2. so every electron in the atom has a set of...

    Do physical objects truly exist or are they just illusions?

    I'm not saying that angels and gods were walking the Earth then and now nor am I saying that they are not. Scientists laugh about the idea, still we are capable of accepting the fact that everything is made of string of the 10 to the power of -34 and it vibrates on different levels of existence...

    Do physical objects truly exist or are they just illusions?

    I would never make the misstake of arguing that nothing is real, if that would the fact then there is no point in discussing anything, cause nothing would be real. And the philosophy you are referring to I have no clue. I've been thinking about the double split experiment. I'm not the one...
