That's right. Math and physics in general are very unconnected in Germany. People do the one or the other thing. Physics is pretty much 95% experimental physics over here in Germany believe it or not. I know that most people from different countries think that math or physics has to be s.th...

Hi, one of my best friends started with 24 and he is now 28 and is making his master in physics. Your question is very tough, because I don't know if it's wise to stop your current, practically finished education for a completely different path. Today physics is largely based on speed...

Cool.:smile: Well, the environment is, that you have certain lectures, then you get homework and have classes where you have to present your solutions. It's often very independent work so you have to know what literature you will need, and how much time you will invest on certain problems. Our...

Thanks, I like the american one. There's nothing special about our approach to science except you have to do all by yourself. It's all very theoretical over here, so don't be shocked. You will study with english books anyway most of the time. Don't know about that one, we have a lot of...

Hi, never mind.

That's your part of the studies to do both of these things. It's not ignored because the class wouldn't understand it, it's left out because they want to see that you can manage this by yourself. We didn't get anything in the lectures close to the problems we should solve. I felt the exact same...

When I hear you talking I think it's myself. Stop complaining and go through the details of the lectures if you are bored. On the one hand you say it's too easy on the other hand you claim the algebra is tedious, that doesn't seem to add up. You have to work through the algebra and gain a...

Thank you very much, it's all about detail :smile:

Hi guys, probably that's the wrong forum, but I was just curious about the plot (Figure 1 Chapter XI A./1. page 1097 / Volume II) of the eigenvalues E(\lambda). If I calculate them they are supposed to be straight lines with positive or negative slope i.e.: E(\lambda) = E_n^0 + \lambda...

Hi, I just wanted to insert my view on the topic. I'm a major in physics. First of all studying physics is very different from studying medicine you can't compare them. Medicine is somewhat more standardized while physics depends much more on the faculties where you are studying. To be...

Hi genneth, thanks for your (very good) explanation. It helps a lot.

Hi guys, I don't understand how one would exactly determine a dispersion relation of phonons experimentally. There are two equations, one for momentum and one for energy conservation: \vec{k} - \vec{k^{'}} = \vec{G} + \vec{K} \omega - \omega ^{'} = \omega(K) where...

Edit: Yeah, you're right. There is only one possibility to move a branch in the 1. brillouin-zone. Thanks.

Hi, I was just wondering if there is any reason why the reduced zone scheme of the free electron gas is looking like here (and in all other textbooks): http://www.pha.jhu.edu/~jeffwass/2ndYrSem/slide19.html I mean I could add any reciprocal lattice vector which moves the particular...
