    Schools Bad economy influencing graduate schools?

    I was wondering whether or not the new state of the economy (recession) will have much of an effect on graduate school as far as whether schools won't offer as many stipends due to increased living expenses or what not. Any insight?

    Medical Physics advice

    Yea, sounds pretty intense. I have a 3.5, but hopefully Rice's reputation will help that somewhat. Is this GPA competitive? I've will have spent all three summers doing research, two of them in nuclear physics which is important to medical physics. Then my senior year I will be working in the...

    Medical Physics advice

    I'm almost done with my junior year as a physics major at Rice university, and I am planning on going to graduate school in medical physics after graduation. But all of my research on the field and the application process has been done online, and no other classmates or professors are interested...

    Time evolution of spherical harmonics

    Oh, okay, I should have realized this. This is for a rigid rotator with Hamiltonian \hat{H}=\hat{L^{2}}/2I So this means that the energies are both: E =1(1+1)\hbar^{2}/2I = \hbar^{2}/I And \left\langle\theta,\phi|\psi(t)\right\rangle=\frac{i}{\sqrt{2}}e^{-\imath\hbar t/I}(Y_{1,1}+Y_{1,-1})

    Time evolution of spherical harmonics

    Homework Statement At t=0, a given wavefunction is: \left\langle\theta,\phi|\psi(0)\right\rangle = \frac{\imath}{\sqrt{2}}(Y_{1,1}+Y_{1,-1}) Find \left\langle\theta,\phi|\psi(t)\right\rangle. Homework Equations \hat{U}(t)\left|\psi(0)\right\rangle =...

    Fourier series of sin(x)

    That's true. Okay, but for bn where n isn't 1, bn is zero, correct?

    Fourier series of sin(x)

    bn = (1/pi) int ( sin(x) * sin(n*x) dx) from -pi to pi becomes a multiple of sin (n*pi) which is always zero.

    Fourier series of sin(x)

    Yes, but if the Fourier series of f(x) = ao/2 + sum over n from 1 to infinity (an*cos(n*x) + bn*sin(nx)) then if ao, an, and bn go to zero, you are left with simply zero as the Fourier series. Shouldn't this method still work?

    Fourier series of sin(x)

    I know it's trivial....but how do you find the Fourier series of sin(x) itself? I seem to get everything going to zero...

    Is there much money in physics?

    Medical physics does sound amazing...but what is involved in being accepted to a MS or PhD program in medical physics? How tough are admissions? Are they as competitive as med school admissions?

    REU Acceptance

    To those of you who have done REU programs in the past, what are they like? Is it like a 9-5 job or what? How much of your time should you expect to be working?

    What it exactly asks i this question?

    Oh yea I missed that initial minus sign.

    What it exactly asks i this question?

    The gradient will actually be (-(e^-2y)*sinx) i - (e^-2y)*2cosx)j .

    Is this the correct formula that im using for this question?

    distance = (1/2)*a*t^2 + vi*t where a = delta v / delta t and vi is the initial velocity (12 m/s)

    Programs BS Applied Physics to Engineering PhD

    I'm a Rice University sophomore majoring in Applied Physics. I decided only within the past semester that I don't want to do pure physics my whole life (mainly due to the poor career choices). So I changed to applied physics. My question now is if it is possible to go to graduate school in...
