    Masters in Mathematical Physics at LMU TUM or Hamburg?

    You are generically saying or saying that I may not have secured good grades ! Just curious...😃

    Masters in Mathematical Physics at LMU TUM or Hamburg?

    But are you still studying😅?! Anyway, There are many age based bureaucracy in my country, according to that this is quite older.. like one cant become assistant prof if someone is >35 years of age & cant get some particular fellowships if you are >30 etc etc... Does happen at other countries also ?

    Masters in Mathematical Physics at LMU TUM or Hamburg?

    Maybe to some extent. But I dont think it is completely true. As I already mentioned, Earlier, I had publication where I worked on calculations and now also working on masters thesis. In both the cases my supervisor seem happy with me. Does not it indicate I dont have that level of ignorance ...

    Masters in Mathematical Physics at LMU TUM or Hamburg?

    Is 8.62/10 really poor performance ? In german universities, will not it count if I have topped fundamental courses like Classical Mech, Quantum Mech, Stat Mech, Electrodynamics and Math Physics ? In my department nobody told me I performed poorly. The reason I mentioned about AI/ML is that it...

    Masters in Mathematical Physics at LMU TUM or Hamburg?

    Yes that's true but what if the PhD positions I'm looking for requires certain background, for example, theoretical physics they require background in QFT, knowledge of dynamical systems etc and some places string theory also.. so as I said my masters don't have any such background. It was very...

    Masters in Mathematical Physics at LMU TUM or Hamburg?

    Hi ! Really Thank you, for your reply. I never tried to say that - since it is short, it would be easy. I was trying to say, since it is a short duration, it would probably be very difficult for me, as my master's program is very generic with no emphasis on any particular area at all. In fact...

    Masters in Mathematical Physics at LMU TUM or Hamburg?

    I am very interested in theoretical and mathematical physics. I am not though from IITs but one of NITs in India - doing msc physics. My CGPA in MSc Physics till 3rd sem is 8.63/10 (to convert in german system, its like 1.8 or something) with top most grades possible in fundamental subjects like...

    Electric field external to Conducting Hollow Sphere with charge inside

    No no, I understand there can be lot of things if we consider microscopic view, there will be Quantum Electrodynamics and so on, I understand that. I just want to stick around macroscopic picture for the time being. But do you mean Graphene is a 2D conductor which can have surface charge...

    Electric field external to Conducting Hollow Sphere with charge inside

    Yes I am already familiar with it, but frankly I do not see any applicabilty or even connection of image method with this problem. Is there any ?

    Electric field external to Conducting Hollow Sphere with charge inside

    Yes, but my confusion is not Gauss' law. The thread is helpful to me because it depicts capacitor metallic conducting plate having non-zero thickness. I am still amazed, that there cannot be 2D metallic conductor or conducting shell with zero thickness having non-zero surface charge density !?

    Oh my bad, really sorry.😂 https://www.physicsforums.com/threads/finding-electric-field-between-two-conducting-plates-using-gauss-law.1053894/

    Electric field external to Conducting Hollow Sphere with charge inside

    Ok I think I do understand your point. I will get back again after some pondering. I just looked at diagrams in this link, which are having finite thickness. EDIT : There was a wrong link I cited previously, here is the link...

    Electric field external to Conducting Hollow Sphere with charge inside

    Then what about conducting plates of capacitor ? We take them infinitesimally thin long metallic plates, right ?

    Electric field external to Conducting Hollow Sphere with charge inside

    You mean that it is not ideal to consider thickness of the shell zero ? Even if it would, it would no longer be a conductor ?

    Electric field external to Conducting Hollow Sphere with charge inside

    Well, If we take hollow sphere having two surfaces, then I understand that the situation will be similar to charge put inside a cavity of a conductor. And the answer will be followed. But that precisely is my dissatisfaction. What if we take thickness of the shell to be zero. An ideal situaiton...
