Thank you! Borek and AlephZero. It is now installed.

Hi, I'm new to Computational physics. I was trying to install Quantum Espresso under Cygwin on a PC. Running the Makefile resulted in two error messages, which I don't understand: " $ make all test -d bin || mkdir bin cd install ; make -f extlibs_makefile libiotk make[1]: Entering...

Townsend is actually our professor. I think the book lacks rigor. Many things are not clearly presented. It seems he wants to say something in the book, but he just doesn't. I had to go to him and ask what really was going on. And I venture to say that most of your confusion comes from this...

Hi all, I like physics and I just finished Goldstein's mechanics. I don't know what my next step should be in terms of textbooks on mechanics. Also I am only a rising college sophomore, and the math I know doesn't exceed an average college sophomore too much. Does anyone have any advices as...

As for CS, I don't how much experience one summer can give you. It really depends on the way you do it. If you do it 24/7. You are probably going to be read for data structure directly or even more. If you don't, then probably not.

I only took one math core, and that was in the first semester. So I don't have much summer math experience. However, I do hear that they go over material pretty fast. I don't know if this is optimal with your memory patterns. But it is indeed pretty time efficient. As for differential geometry...

Alright, I will answer your questions for my roommate. I think you should learn as much math as possible. With only single variable calculus, it is difficult to do much in physics. Also I heard that Feynman lectures are not good textbook books. They are very good at enhancing your physical...

Hi, I need to learn Landau-Lifgarbagez-Gilbert equation for one project. So I'm wondering how much stuff I need to know before being able to understand this equation. I have taken a standard upper-level undergraduate electrodynamics. (We finished Griffith). Unfortunately, I haven't taken any...

Why is partial derivative with respect to time used in the continuity equation, \frac{\partial \rho}{\partial t} = - \nabla \vec{j} If this equation is really derived from the equation, \frac{dq}{dt} = - \int\int \vec{j} \cdot d\vec{a} Then should it be a total derivative with...

Hi Everyone, I'm trying to go through Jackson this summer after having finished Griffith. However, it doesn't seem feasible to do all the problems in Jackson. So I'm wondering if any of you have a electrodynamics syllabus (with problems number on it) with Jackson's book and can give me the...

I'm new to quantum physics, too. But here is my take: One. For a nonrelativistical particle, assuming only one, the wave equation can be solved using Schroedinger Equation, given a certain potential energy distribution. Many times, there are many eigensolutions to Schroedinger Equation, given...
