(Also, screw assembly code, for now, just focus on learning a more powerful language)

It's worth noting, that while you are learning from courses, it's a good idea to have your own little side projects too. I've found that, personally, I just can't learn from "teach yourself xxx" courses, and I learn by trial and error. My latest adventure was into programming for Android (which...

You can see galaxies with telescopes on Earth, what do you mean?

Sorry, that was a typo. Should have been e^(-lambda x^2)

Thanks for checking. Turns out, the model answers were a bit badly written. They had put in the factor of two, because the integral was changed from -infinity to +infinity, to 0 to +infinity, so you can make use of a definite integral \int_0^{\infty} \! e^{-\lambda x} =...

Homework Statement Consider the wave function \Psi(x, t) = Ae^{-\lambda|x|}e^{-i\omega t} where A, \lambda and \omega are positive real constants. Normalize \PsiHomework Equations \int |\Psi(x, t)|^{2} dx = 1 |\Psi(x, t)|^{2} = \Psi^{*}\PsiThe Attempt at a Solution I have a model solution -...

Homework Statement A long circular rod of radius R, made of conducting material, has a cylindrical hole of radius a bored parallel to its axis and displaced from the centre of the rod by a distance d. The rod carries a current I distributed uniformly over its cross-section. Consider the...

Homework Statement Indicate the (111) and ([11]0) ([11] has an over line, so is negative, don't know how to do on forums!) planes in a cubic lattice in a diagram, then calculate the angle between them. The Attempt at a Solution I think I have drawn this right (see attatchment), but I am...
