Mar 8	comment	How can new interpretations of QM help? Is there really no interpretation which one day would make calculations better? What is the easiest QM interpretation to teach? What are axioms good for if the imply derivations which you cannot follow in physical understanding? OK, I see where QFT is used. But I guess it will not make the double slit experiment physically more intuitive?
Mar 8	comment	Conserved quantum observables from symmetries with density matrix This seems to already assume QM framework? Ballentine derives representations in terms of position and momentum for the Galilei group. Can I do the same with the density matrix? Because at the beginning I don't even know that such of thing like $\hbar$ exists. It has to be derived.

Mar 8	comment	How can new interpretations of QM help? @Zaslavsky: Sure, but it's up to the reader to read the full question with all explanations. I could add: Does any of the interpretations potentially help advancing technology? That's all what matters really, unless you are researcher who is getting paid. It's about practicality and results and not fancy mathematical frameworks which lose imaginability of reality.
Mar 8	comment	How can new interpretations of QM help? Can you think of interpretation which potentially could make the most difference? Does QFT offer any insights into the simple double slit experiment? I mean saying the particle considers all paths and then behaves accordingly is even less intuitive than non-locality etc?! Later I'll have a look at geometric QM. But at first glance it seems like mathematical reformulation which makes is mathematically nicer but physically less understandable?!

Mar 4	comment	Why does electrical current start to flow? I also heard that the EM field plays a key role. But your other post doesn't really answer this particular question, as merely saying "there is a voltage" provides no concrete information. I added a comment to this question above.

Mar 3	comment	Why does electrical current start to flow? I've looked at the question, but it is not going in the same direction. The most important part in my question is to state the EM field for all points in space and then explain how that drives the electrons. The answer there only mentions there is "voltage from the power plant", but it doesn't draw the whole picture.

Feb 25	comment	How are fundamental forces transmitted? Thanks. There are sort of similar questions, but my specific question how localization and distance come into play I couldn't find (it only mentions "quantum field" without further explanation which would help me). Maybe someone can elaborate on locality in particular?

Sep 9	comment	How do you prove $S=-\sum p\ln p$? @Ron: I'm not saying you are wrong. I'm saying you just haven't given an answer related to the question. And I made the experience that generally people who start their answer with either "It's very easy and well known" or "I know where you are wrong" usually haven't understood the question. Feel free to check my posts word by word.
