So all these industry jobs are all not about physics. I know i'll probably sound naive, but being young, i really hope i'll always be able to do what i had been studying for. If i got it right, you're suggesting me to stick with particle physics, with the drawback that probably my job won't...

So you're basically telling me that academic career is desperate in both cases, although in AMO is slightly better? Speaking about industry, i can hardly think of the way a particle physicist could be useful in industry, could you explain me this point? I already knew that computational...

Hi everybody! I'm an italian student, I'm about to get my bachelor in physics, and naturally the next academic year I'm going to begin grad school. My problem is: starting with the fact that I'm with no doubt a theoretical physicist, i'd like to know if, as far as regards career, it will be...

Well, i read the other topic but i think that didn't help much. If that's the case then why do we define these quantities in quantum mechanics? As you say in the other topic (if I understood correctly), post number 9, an experiment would perturbate the particle and could give it such...

I know that the wave function goes to zero, but if I do the integral of |psi|^2 between a and b for example, where a and b belong to the region in which the potential is V, then i would have a non-zero probability to find the particle in that region of space!

Hi everybody! I'm studying the simple case of the solution of the Schrodinger equation for a step potential "[URL .[/URL] As my professor states , the transmission coefficient is 0 when the energy of the particle is E<V. I really don't get how this result is not a contradiction with the fact...

Ok,i think i understand now, thanks a lot guys :)

I know that, i just want to know if the two potentials must have the same sign, or the opposite sign. Suppose, instead of a spring, the plane in which the motion happens to rotate with a constant w. In this case there would be a potential, due to the centrifugal force, given by V1=...

Hi! I'm a new user of this forum, although I've been reading a few threads for a while... Mi question is this: in rational mechanics, how do i decide the sign of a potential? Let me explain better: in some exercises it may happen that a mass particle is subject to both gravity and, for...
