I'm not sure if trying to convince me if I should go back to "no interpretations of QM" .... Or should somehow be in a superposition of "no interpretations of QM" + "Copenhagen" :P

hey vzn ... Im not sure if u were following the history of I reached the comment above ^

@MoreAnonymous hi saw you questioning/ discussing QM interpretations at length. fyi there are new research findings to consider not taught in classes/ textbooks. :)

@vzn Here is some of the mayhem spurred by trying to learn about different interpretations:

https://physics.stackexchange.com/questions/502221/does-the-copenhagen-interpretation-allow-one-to-bypass-a-derivations-objection

https://physics.stackexchange.com/questions/502211/how-many-worlds-are-there-during-branching-in-the-many-worlds-interpretation

https://physics.stackexchange.com/questions/502427/how-is-the-collapse-postulate-is-also-present-in-qft-only-hidden-inside-the-ls

To be fair the LSZ formula having anything to do with the measurment is schocking!! and less to do with the measurement

I mean less to do with interpretations of QM

@MoreAnonymous there is a quantum-interpretations tag on the site but the topic is (sometimes very) unpopular among regulars as oft expressed in chat. are you undergrad or grad student? what country?

More Anonymous

I've done 2 masters in theoretical and mathematical physics

vzn

ps congrats you are visitor #100 to this chat room :)

I've gone back to my home country and am currently hating the cooperate life :/

Thanks!!

vzn

@MoreAnonymous cool what country? did you write Msc theses?

@MoreAnonymous you have a corp job? what kind?

More Anonymous

India

Thesis: Twistor theory in particle physics
Thesis: Behaviour of QFTs under Robinson Boundary conditions

Job: Data Scientist intern

how about u?

vzn

5:33 PM

@MoreAnonymous saw that interesting String blog you cited in Physics... what kind of data science are you working on? you say you went back to your home country India? from where?

@MoreAnonymous corp job java + web + big data

More Anonymous

If by String blog u mean "Not Even Wrong" ,.. It would be more accurate to call it an Anti-String blog ... Im working on locations (Google map sucks in India ... Its useful but not as useful as UK) .. yea Im in India .. came back from the country of Brexit

Found it!! https://4gravitons.com/2016/05/13/particles-arent-vibrations-at-least-not-the-ones-you-think/

More Anonymous

Ah that one! yes! its a good blog as welll

vzn

anyway there are some new interpretations of QM emerging, think you will find them interesting at least, can fill you in at length if you are patient.

More Anonymous

Id prefer the source (if ur up for it a summary would be nice too)

Meanwhile in the physics chat room it seems u can theoretically do the double slit experiemnt with blackholes instead of electrons

vzn

5:47 PM

@MoreAnonymous not sure what you are referring to there.

Quantum Leaps, Long Assumed to Be Instantaneous, Take Time / quanta mag

More Anonymous

Ah ... I remember this one! And people posting in physics stackexchange why that would be a problem for QFT and also Lubos loosing his shit claiming that while the paper is a useful modelling tool its not a correct assessment

@vzn here: chat.stackexchange.com/transcript/message/51684564#51684564

The jist of it is you can have a universe with a blackhole heading towards a topological hole would be have as a slit!

I mean to be fair while Quanta is a gr8 magazine u do have the occasional physicist (with respect to his paper) saying massive bullshit on it :/

vzn

@MoreAnonymous so youre a Lumo fan. he commented on the new "quantum leaps" findings? do you have that link?

@MoreAnonymous generally like quanta myself and the article is a popsci writeup of a (very recent!) science/ experiment result reported in a peer reviewed paper (afaik)

More Anonymous

Think its this one: motls.blogspot.com/2019/06/experimenters-and-especially.html

Here's a gr8 example of quanta bull: quantamagazine.org/…

And here's why its bull: math.stackexchange.com/questions/2211278/…

And please never call me a "Lumo fan"

vzn

@MoreAnonymous a Lumo citer?

More Anonymous

I mean ... I was recalling the mayhem that followed ... In the physics stackexchange someone cited Luubos ....

vzn

5:58 PM

@MoreAnonymous re Riemann-QM links, they are deep and have been explored for decades by prestigious authorities... but ofc not everything in the area is solid... blogged about this awhile back... collect links on it myself... an area of strong interest for me...

More Anonymous

So maybe a lubos citer is close but ....

@vzn I mean so what's ur thoughts on the criticism I mention

here's a better link: mathoverflow.net/questions/287741/…

While I think Riemann-QM (relationships) is fruitful ... I think physicsits trying to use QM to prove RH is .... Well impossible :/

vzn

@MoreAnonymous thx for the links. want to blog on it again. its an area of interest for me but not really my expertise. think there is some overall general validity to the QM-Riemann study seen in many other papers. "the devil is in the details™" as for quanta, much popsci is criticized by hardcore scientists as inaccurate... it seems a common refrain...

More Anonymous

I mean ... I visit it quite often myself and 1 or 2 outliers don't make spoil the entire experience for me

Also I'm currently of the immpression that you can get different mileage from different interpretations of QM: see this one: physics.stackexchange.com/questions/502221/…

Going back to the orginal topic and devil in the details

vzn

@MoreAnonymous its some optimistic hype for some new ideas. seems harmless.

More Anonymous

I hope this optimistic hype refers to Quanta and not my stackexchange post :P

vzn

6:07 PM

@MoreAnonymous have been studying QM interpretations for a few decades now. have copious refs, & developed my own particular flavor. can guide you thru it, think you will find it at least interesting and maybe compelling. but do suggest/ recommend after long experience Physics is generally not a receptive audience for the subj.

More Anonymous

Also u have to be careful people of the physics community were furious when the "faster than light neutrinos" were announced by cern ... And for good reason (and yes a paper was written claiming these results)

vzn

@MoreAnonymous science is a human endeavor and therefore has the same or "corresponding" flaws...

More Anonymous

@vzn agreed :)

Also I'm curious what you have to say about this specific question on physics stackexchange?

vzn

@MoreAnonymous are your theses online? itd be great to check em out :)

@MoreAnonymous this one?

More Anonymous

Im not sure but I never did well in them ... the first one I agree I did terrible ... the second one while the Prof was happy with my reasearch I didnt do a good write up :/

This one: physics.stackexchange.com/questions/502221/…

vzn

6:15 PM

@MoreAnonymous (+1 for some effort/topic) maybe there is some clear question here but think its phrased in an unclear way. what "quasi-classical measuring apparatus" are you referring to?

More Anonymous

Ah theres the exact same question in the comments

which I answer with:

So in the Copenhagen one can give the apparatus a special status. The user bolbteppa says "A measurement is an interaction between a measuring apparatus which is (quasi-)classical and a quantum system You can model this, it's in Landau's QM section 7, I don't want to quote the whole thing, but this wave function collapsing business is pretty straightforward there without all the woo"

vzn

@MoreAnonymous so you edited the question based on feedback? ok... ps have talked to some of your correspondents for years over QM interpretations eg bolbteppa, John Rennie, ACuriousMind etc

More Anonymous

Maybe I should edit rather than leave it in the comments

vzn

@MoreAnonymous my suggestion is that you have very valid theme of questions, hence me inviting you here, but think the answers you are looking for will not be found where youre looking. aka these are not the droids youre looking for™ lol

More Anonymous

AcuriousMind was the one who excepted my doubts were legitimate and bolbteppa was of the opinion bullcrap (probably because of Copenhagen). Hence the quesiton

vzn

6:20 PM

@MoreAnonymous ACM has said in chat repeatedly he doesnt care much )( about QM interpretations.

More Anonymous

yea ... but in this case it seems he understands atleast what Im saying

vzn

@MoreAnonymous he has some )( philosophical side.

More Anonymous

@vzn if ur reading through the post and its context (which I agree its massive)

Lemme know if u need me to explain anything
