    Internships in physics for summer?

    Hello! I'm a student from Kiev Polytechnic Institute, Ukraine. This summer I'm coming to the US for Work and Travel Cultural Exchange Program. Can anyone tell me if it is possible to find any kind of an internship or a temporary job related to physics, if so where can I apply for such a...

    How to Solve a 3rd Order Differential Equation for Alfven Waves?

    how come that I can take xS'\approx-3/2? I've calculated c(x) as you proposed: c(x)=3/2lnx+C1x^2+C2x+C3. So the final form is like f(x)\approx Ae^{c(x)} Daymn... i don't understand that WKB method...

    How to Solve a 3rd Order Differential Equation for Alfven Waves?

    Hi! I need to solve a differential equation for my bachelor's project. Rather i need to find a asymptotic solution, when x goes to infinity. That eq. describes Alfven Waves in rotating inhomogenious plasmas, accounting effects of finite larmor radius. So the equation is as follows...

    Asymptotic solution to a differential equation

    http://djvu.504.com1.ru:8019/WWW/888e7f7367ba8f0f0eb381b0cadf0de4.pdf p. 230 change the dependent variable from y(x) to u(y)=y'(x). Then the Order of the eq. will lower by 1. Note: NOT u(x)=y'(x), BUT u(y)=y'(x)

    Need Help with an Asymptotic Solution for a Differential Equation

    Hi community :P Need some help with a differential Equation: 3/2y(x)+xy'(x)+y'''(x)=0 actually I'm looking for an asymptotic solution, when x -> infinity. I made some research about that Eq. and here what i have found: 1 guy found an asymptotic sol. for a more general eq...
