    Expectation Value/ Evaluating Gaussian Integral

    Try setting x in terms of u. I didn't follow the whole thread, but I believe u=(x-xo)/k. So solve for x in terms of u, put that in and the integral should be more manageable... though you'll still need integration by parts, no way around that.

    What Are the Top Unresolved Questions in Theoretical Physics Today?

    I'm not a huge expert but let me clarify a couple things for you. Your points 1,2,4,5 are all really the same thing in the sense that you are talking about grand unification (well not #2 strictly, but its related). Unifying quantum mechanics and general relativity is probably the #1 thing on...

    Force on charges inside/out of a hollow conductor

    Homework Statement Two charges, q and q', are located respectively, inside and outside a hollow conductor. Charge q' experiences a force due to q, but not vice versa. Prove this statement and explain the apparently violation of Newton's third law. There is no net charge on the conductor...
