    Other Second thoughts on Medical Physics PhD

    To address Choppy: I have spend some time with a medical physicist at our local cancer center to help with the QA and monthly calibrations of some of the systems like the True beam and such. I found the task to be extremely mundane, and sort of mindless. I guess I am unaware of what tasks a...

    Other Second thoughts on Medical Physics PhD

    Hello all, So I am experiencing a major amount of doubt about going to my phd program. I am a recent MS physics graduate with a BS in physics as well. I recently accepted admissions to a very good medical physics program in the midwest and was granted a university fellowship for a year (or...

    Thank you Choppy! Thats very insightful. Though I mentioned I am not interested in academia work, I am not against research. It just is not my primary goal. My primary goal is to have more direct impact on people's lives through the field of physics. Secondary is a strong job that can provide...

    Summer program project ideas

    This is a science program for Juniors and Seniors that are either from low income families, and/or soon-to-be first generation college students. The director literally told me I can focus on one area of a science or go very broad. I was also told I can do a big project or a few small projects...

    Summer program project ideas

    Yes, i will be teaching high school students. I have no knowledge of their math background either. I was thinking that it might be in my best interest to either have them perform 4-5 projects in small groups, or have them do one big project. Then discuss the theory very generally with them...

    Translation operator on ground state

    right. The First order terms disappear. But the second order terms are the ones I'm worried about now. Σ(|<m| v |0>|^2)/(Em-Eo)

    Translation operator on ground state

    the perturbation is in the form of v sin(cx). I need to calculate the lowest non vanishing term to the energy of the ground state.. Im assuming that the nature of sine being an odd function will make first order terms disappear, but not the second order terms.

    Translation operator on ground state

    Guess it's x that is the operator and yes it's a harmonic oscillator and the perturbation is a trig function. But if I write it as an exponential I get the x in exponential. I can write it as a combination of creation and Annihilation operators, then separate them. But how do these act on the...

    Spin time development

    So I started over and found the EigenVectors of the hamiltonian at t<T (Interval where B points in X-direction).. \mid\alpha\rangle = \dfrac{1}{\sqrt{2}} \mid +\rangle_{x} e^{\dfrac{\imath e B_{x} t}{2mc}}+ \dfrac{1}{\sqrt{2}} \mid -\rangle_{x} e^{\dfrac{-\imath e B_{x} t}{2mc}}\\ Where: \\...

    Spin time development

    AH. well I'm confused now. \vert\alpha, t \rangle = \dfrac{a}{\sqrt{2}} e^{i t\dfrac{H}{\hbar}} \vert +\rangle\pm\dfrac{b}{\sqrt{2}} e^{i t\dfrac{H}{\hbar}} \vert -\rangle the summed state represents spin up in z and difference terms represent spin down?
