    How to integrate -exp((s^2 - t^2)/2)*(f'(t) - t*f(t)) dt

    Hi, I'm currently studying for my PDE exam, but my fundamental calculus skills might not be the best. I typed my question into wolfram alpha (http://www.wolframalpha.com/input/?i=integrate+-exp%28%28s%5E2+-+t%5E2%29%2F2%29*%28f%27%28t%29+-+t*f%28t%29%29+dt) and the result is correct, but I...

    Why some metals are not superconductors?

    Hello, I'm studying about superconductivity. So far I understand that the material needs have zero resistance and meissner effect to be a superconductor. But why materials such as copper or gold are not superconductors? I think it's something to do with some quantum effect like cooper...
