It is a good point you are raising about the accelerating observer, Drakkith. I haven't thought about it from that perspective. I am also a bit curious as to how one could express the magnetic/electric field near an electron. In wires and conductors its generally pretty easy to use the current...

I've got a question regarding the magnetic field of an electron, and wheter or not it has some form of "self inductance" or resistance to be put in motion. The magnetic energy per volume is equal to u= 1/2*μ*H2. Say I've got an electron at rest, then the energy of the magnetic field is zero...

I had some MATLAB programming in an introductory course, but we only scratched the surface. But I'll look into it! I have the impression that MATLAB is tought as a tool in other courses. Good suggestions, I did not think about many of them as possibilities.

I am from Europe (Norway), so minor/major does not really translate directly, afaik. I would probably classify it more like a physics degree with an engineering minor. I can add that it is an integrated masters degree, so it is 5 years in total. I can list the courses I am required to take...

Thanks for the answers! The examples with the book and the plastic bag were just to create pictures of what I was talking about - the thing is, more generally, that I cannot think of any two objects that will stick together that way. Not even two smooth surfaces made of roughly the same material...

Thanks a lot!

That is interesting! I was trying some gauge block a while ago, but they did not have to be perfectly clean in order to work. Wikipedia also says this, implying that air pressure is (probably) not the biggest factor: Air pressure applies pressure between the blocks because the air is squeezed...

If I run a current through a wire with a 90 degree turn, what prevents the electrons from continuing out of the wire is a straight forward path? What force accelerates them in the direction of the wire?

Hey, I was just thinking a bit about vacuum and air pressure and suddenly came over something really simple I cannot explain. I know that it is the external air pressure that makes two halves of a hollow sphere containing vacuum stick together like in this picture...

I guess it is an idea to take some finance or something, but I'd rather aim towards technology/science :)

Hey, I am strongly thinking of switching from mechanical engineering over to engineering physics. I am thinking of taking the first year again, and will therefore have about 5 courses I can choose freely. So the question is, what courses could be a nice addition to a engineering physics degree...

Hmm... I am aware of that difference between science and engineering, but I would maybe believe that the distinction between them is a bit more floating. Electrical engineers have for example been doing quite fundamental research that have been awarded the nobel prize in physics. Engineering...

Why do you really care what are the big problems of the day? Are you concerned with your image, or with something that personally interests you? Is you objective fame (the guy who discovered ...), or do you simply want to do something interesting and useful? Interesting question. I think it is...

Hello! I am currently doing my first year in a mechanical engineering degree(which after a few years branches off to applied mechanics), which is a 5 year integrated master's. Since before i applied, I have been uncertain about which study I really want to/should do, and that uncertainty still...

oops, should have been posted under "career guidance"
