When they know you´re the one grading their exams, they kinda do. :) I do know, however, what you're talking about. Although they're not disrespectful at all, they certainly don't take me as in such a high ground as the professor. That's OK. I'm just using my time with them as a practice when I...

Thank you for your advice, guys. I must say that I am not the main lecturer for this class I was talking about, I'm just their TA; but I want to become a lecturer after I graduate, so I feel it's important I find ways to keep my audience interested. I do present them with puzzles and questions...

Answer 1. I want to involve time-travel. The cloning makes sense, but it wouldn't have no time travel in it :( Answer 2. Yes, the person remembers the process. Answer 3. No paradox at all, if they put the person back. Or not?

Hi, all. I want to become a Physics professor in the US. For a few years now I've been a TA in an american university and I've had to teach a few lectures to a large audience in a big lecture hall. However, american students learn differently. For moments, I feel like a performer in this...

Really? I think I was looking for the wrong author. Thanks, I'll look him up.

Thanks for your replies, Simon & Ken. It looks like your estimate for v < 0.5c seems convincing enough. In any case, allow me to be more specific. I want to consider the problem of a neutron trapped in the core of a NS. I want to consider an extremely oversimplified treatment: my neutron is...

Yes, I'm asking if the thermal energy is enough to consider relativistic corrections (i.e., v ~ c)

As the title of the thread suggests, I'm interested in estimating the velocity distribution of neutrons in neutron star cores. Putting T ~ 10^12K gives v ~ 15%c or more under Boltzmann statistics. Could someone provide more information or a second opinion on this estimate? Thanks.

Thank you. I bumped into Baebev's work, but it's all in Russian :confused:

Hi, PF: I'm currently about to graduate from my Ph. D. program in Physics and I want to focus my research in theoretical physics. I feel very excited by topics such as Astrophysics and GR, but also low temperature physics, such as superconductivity, bose-einstein condensation, superfluidity...

My current status is F-1 [student non-immigrant]. I plan to apply for an employment authorization [OPT]. The visa issue is yet another downsize. I don't know how big of a disadvantage I'm in for not holding a green card. Online job postings, mainly from 'physics today' website...

Dear PF: I've spent a decade-plus in school by now. I earned my BS in a country different than the US in 2002. My degree allowed me to work as a Math & Physics teacher in high schools in my country, but not in colleges or universities. From the beginning, I knew I didn't want to be a high...

Thank you. I like intriguing stories, the kind of ones where things start making sense as you keep reading. Your comment seems to suggest the story is fulfilling this purpose. :approve: No, not at all. I haven't consider any of the comments as attacks and you have my sincere gratitude for...

That sounds very nice, but I already worked out the 'rules' for the time-machine and the "Relocation" process, I just don't want to reveal too many details. As I and other commentators have pointed out, there is a heavy moral dilemma, but I want this moral dilemma to play in the background of...

I see what you mean now. So, because we have to have an integer number of half-waves in the right-half of the waveguide, only those will that have a node along BH_0 will make it through. That would imply then that the wavefunction is forced to have a node along the BH_0 line, would you agree?
