@HerrFeinmann i wanted to tell u that i recently got the coolest journal ever and it claims to be handmade in italy
btw do u think statements like this are offensive? i do not wish to be unknowingly obnoxious american
@Relativisticcucumber what do you mean offensive? :P
I do not consider anything inherently offensive, except claims questioning my integrity
@HerrFeinmann it might be offensive if Italians had some cultural norm against writing things down :P
what do u all think about anti realism
God give me the patience :P
ive been thinking for long that the only meaning of truth can be in terms of its utility. i.e. something is true if it behaves like it is true, and the expected behavior is defined by humans for utility purposes
18:15
@RyderRude Several people have recently expressed that they don't really enjoy these attempts at "philosophical" discussions. Yet your idea of respecting their wishes is to post a random Wiki article on philosophy and ask "What do u all think about this?"?
@ACuriousMind sorry. i did elaborate a bit later in the above message
I do not consider discussions about nationality/stereotypes offensive. Heck, I would not consider even direct insults to Italians as offensive. Beware, I mean personally, of course I wouldn't abide by a negative statement about an entire population, just saying that it sure doesn't touch me personally. I'm not a patriot (not that I hate my country) :P
@RyderRude You just gave your thoughts, unprompted. This is exactly the kind of "amateur philosophy" the highly-starred message from John is about. I'm asking you to read the room.
I just do not find any benefit in pride and attachment towards one's nation, I guess. I respect people who do, I don't like if they tell me I should. It may sound simplistic, but the place where I was born is not the result of my own efforts so I see no reason as to why I should really feel proud
@ACuriousMind i am trying to start a discussion, which is why it is unprompted. and I would disagree that I am doing amateur philosophy now. i was doing it a few years ago but now I am more nuanced. also, i had addressed John's concerns in a reply
18:20
@ACuriousMind is "read the room" an intentional pun? :P
my questions and answers have been getting many upvotes on philosophy SE. And it is a low activity website
so I am not doing amateur philosophy
@RyderRude I'm telling you that people are starring this because they mean your attempts at discussing philosophy regardless of whether you think it is amateur or not. Trying to argue you're not technically the literal target of the statement is just you failing to read the subtext once again, which is why I'm spelling it out for you: People want you to talk less about these random topics here.
2
@HerrFeinmann I think most people would still consider it some form of offense if a group they're part of is insulted, regardless of whether they're proud to belong to that group
@ACuriousMind then i will talk less philosophy now compared to my current rate. but I would also disagree that I am doing amateur philosophy. i think people shouldn't judge me before discussing
I do not judge that and respect that, I was talking about me. I wouldn't feel personally offended, rather I would feel annoyed by the speaker assuming uniform distributions for a big population
i will talk philosophy less now
18:29
@HerrFeinmann i feel like some people might say "it's weird that you want to tell that person a random fact related to italy" bc like i see "made in italy" then i think of u so people might say that is offensive
about one or two days in seven days
i mean idk to be honest i feel like in the US if you make any claim involving race or ethnicity people say this is racist. like it's racist that i saw the notebook and thought of u bc im grouping italian things together
im v confused about this entire concept tho which is why i asked.
@ACuriousMind anyways, it was not about a normal group. I could be offended if you insult my - say - 10 people group, I was talking about such big groups that make the "offense" laughable
@RyderRude If you think the solution to "people don't want me to talk about that here" is to talk less about it and not just stop, I don't really know what you're doing here. This room isn't a space where everyone is entitled to talk about topics that annoy other users X days a week. It's supposed to be a space where we don't annoy each other.
If you want to be an egoist that just types stuff in here without seeking to engage in an actual conversation that both sides can enjoy or benefit from, then you're not welcome here.

@Relativisticcucumber Yeah, I understood you were talking about that. Well, with me - so long as the discussion is theoretical - you can talk about everything. My only trigger is if someone questions my integrity. I have no problems with any topic if it's discussed lightheartedly. Concerning controversial topics, the same thing holds, so long as it's theoretical, if your point is just discussing that, I have no reason to be offended :D
18:34
@HerrFeinmann I understand your point, it's still rather unusual to say you're not offended at all, that was all I meant :P
@HerrFeinmann yippee
@ACuriousMind how ab when i say like "i learned a new german word it's [insert]" do u think this can be offensive
i hope im not just being hella weird
now that i think ab it if someone said to me "i found an awesome journal that claims to be handmade in the us" im not even sure what i would think. i mean maybe id be like where can i get one xD
@Relativisticcucumber no, I think it's perfectly normal
@ACuriousMind but i sometimes do get discussions here, which is why i don't aim to stop discussing philosophy. i think some people do discuss it sometimes like PM2Ring, Slereah and JohnRennie (sometimes). i will post prompts maybe and see if i get discussions. I won't take much space
@ACuriousMind As I said, I meant that I'm not offended on a personal level. I get annoyed because of the ignorance of such claim, not because they "did the gang dirty" :P
Amit also discusses it, but Amit hasn't been visiting the chat
I understand where you're coming from, anyways, I see a lot of Karens on the internet
i think it is wrong to completely restrict me from trying to discuss philosophy
What's the male version of Karen?
steve
i kind of feel like there's a culture in the US of getting offended on someone's behalf
it makes me anxious
18:37
@Relativisticcucumber I think it's very common to try to connect with people from other cultures with the few things you may know about their culture. I do it with international colleagues all the time (and they with me)
unless the thing you "know" is some kind of loaded stereotype, there's nothing wrong with it
Apparently it's Chad (the name), Ken or Male Karen
no no not chad
chad is like
a flexer
@ACuriousMind yippee
I'm not talking about the chad meme. I'm talking about Chad, the name.
wait arent u talking ab like culturally what the male version of karen is tho
i think chad and ken already have other meanings
like a ken is a dumb bf
It seems that according to the Internet Ken is also that
18:40
but if none of the people absolutely ever want to discuss philosophy with me, i will stop it
But we may agree that a gender neutral Karen is ok
wiki says "Some people say “Ken” is the male term, but since the release of the Barbie movie, that name has taken on other connotations. People also sometimes say “Chad,” but in slang, a Chad is someone who exudes masculinity and dominance, so it doesn't quite fit."
@HerrFeinmann true i think that's the most sensible
but I think I have recently had discussions. so it is not that no one wants to discuss it
By the way, call me a horrible person, but I make (and receive) racist jokes with my international friends quite often
there was a discussion about language about 15 days ago
18:42
I think it's important to allow people to discuss
i think it prob just depends. i think some things are well beyond the scope of reasonable humor, but i kind of agree that, if done in a friendly way, this is natural. in china this would happen btwn me and my friends all the time.
it was with PM2Ring and qwerty
before that, I had one discussion with JohnRennie about free will
i think also historical context matters and can make some things v sensitive
@HerrFeinmann well, there is a difference between what you say between people who are friends with each other and have past context and what you say to a room full of strangers :P It's normal for friends to transgress boundaries that they wouldn't cross with a stranger
for example i dont think slavery is ever funny to joke about but my friends will mock me if i try to put the vegetables in the hot pot before the meat.
18:44
Overall I have learned a lot from Ryder Rude since he is willing to help me on many things that I am stuck on
@DIRAC1930 thanks
@ACuriousMind Yes, of course that's why I said that I do that with friends. Then, in general I have loose boundaries :P
Of course I will not transgress limits here or with strangers
@Relativisticcucumber ...what's funny about putting the vegetables before the meat?
@Relativisticcucumber I think any of us has their moral code about dark humour. I do not condemn well done jokes, but I have some flavours of dark humor I can laugh about and others I cannot. Racist and sexist dark humour can make me laugh, jokes about illness and tragedies do not, for example. In my case, death/physical pain are the boundary
@ACuriousMind I think that's the Chinese (hey hot pot is Chinese) version of putting milk in the cup before cereals
18:49
@DIRAC1930 also, my favorite equation is $G=e^{At}$. I mean the one which relates lie algebra to lie group
@HerrFeinmann you eat your cereal from a cup???
Cup... mug?
The usual container would be a bowl
Well, a bowl can be better but a mug with milk and cereals is not bad!
I do actually use a mug though :P
not bad, just weird :P
18:51
I used to drink from a bowl when my breakfast included 400ml of milk
Maybe this sentence is not very grammatical
you must have strong bones, then
My wrist has been hurting for two months, after punching a closet... Bad moment to say it :P
💪
Bruce Lee would say "closets don't punch back" :P
Or is that^ too close to the boundary of physical pain?
@HerrFeinmann i too eat cereal in a mug at times
@ACuriousMind feynman is right. i think the logic is twofold 1) the meat flavors the pot 2) you should fill up on the most OP foods first so if anything goes to waste it's noodle or lettuce or smth. these are the reasons i have been told at least.
19:05
@Relativisticcucumber I understand what you mean but using "OP" for food is funny to me
What is even overpowered food, spinach?
Almost a half litre of milk.
One can gain a lot of weight on milk.
Tyson Fury showed the boxing world that he can put on 20 lbs in 6 months to fight Usyk, so he should know what overpowered foods are.
@Slereah I guess every drink that packs a punch
On the judges score cards he didn't pack enough punches though.
I was looking at en.wikipedia.org/wiki/Gamma_matrices#Trace_identities for the following identity is $Tr[\slash q_2 \gamma^\mu \slash q_1 \gamma^\nu]=Tr[\gamma^\sigma q_{2 \sigma} \gamma^\mu \gamma^\nu q_{1 \nu}\gamma^\rho]$. But I didn't find anything useful. Is there such an identity case?
20:10
what is the point of solving the zero field ising model? is it just to serve as a starting point to perturbatively solve for the nonzero field ising model?
@ACuriousMind According to ref. 1 it is indeed correct.
@SillyGoose do you mean zero external field?
@HerrFeinmann yes
also lmao
Arthur Eddington was extremely underrated
It appears that he took the Dirac equation further than anybody of his time period
@DIRAC1930 You mean the guy who published a gigantic book of his insane QM theory
In the Ising Hamiltonian $$-h\sum_i\sigma_i-g\sum_{ij}\sigma_i\sigma_j$$ you have two relevant physical limits: $$h/g\ll1$$ and $$h/g\gg 1$$
20:16
@Slereah Yes lol he published 2 but the last 1 was published posthomously and seems a lot more speculative than his first
From some authors I have been told that he was patient zero for quantum mysticism
One situation is an ordered phase (SSB), the other is disordered (no SSB), you can check comparing the GS
inventor of the quantum nonsense
Hopefully one day I will get time to go through his first book
Also, the interaction between the dipoles and the field is pretty simple, the most important physical part is the dipole-dipole interaction in the Ising model. Of course if you have both you have the complete situation, but studying only the dipole-dipole term can help you understand a few things about the model
Then, as you say you can consider both the limits above and make a perturbation expansion
20:22
@HerrFeinmann well an exact computation does not exist for classical 2D ising in exernal field still :P
I don't know much about Ising and I can't even solve the 2D model without a field, because I never considered it interesting enough. Nevertheless, the zero field model can be useful for a bunch of things, such as understanding renormalization
i see
the zero field model is also very hard to solve :)
i am using it to explore ssb
Schrodinger, Heisenberg, Dirac and Eddington are all crazy in the best possible way
@SillyGoose You may be interested in Sachev QPT
Another physicist that is underrated is Pauli. He seems to be only known for his exclusion principle but he contributed so much more
20:26
yes
ill take a look thank you
@DIRAC1930 but i think Schrodinger didn't contribute much
his only main contribution is the non rel single particle Schrodinger equation
the others have done multiple major works
@SillyGoose you're welcHONK
Well he found the rel version too but it had problems so he only published the non-rel version (there is an interesting story by Dirac)
yes. he had the Klein Gordon eqn
20:29
@HerrFeinmann ::groans::
He published many papers but a lot of them seem to be ignored
people back then already knew that they had to look for wave equations. and De Broglie relations were already known. based on that, Schrodinger developed his stuff
but I think the work of Dirac is a much more deep
the idea of canonical quantisation is miles ahead of everyone else
He also did a lot of work in GR which apparantly was flawed but I don't know much about
still Heisenberg and Schrodinger walked so Dirac could run
Dirac also came up with QFT!! I'm sure he is the greatest physicist of those days
not sure why he isn't as famous as einstein
i think Einstein's reputation benefits from pop sci
Oh boy, it triggers me so much when people tell me that I believe in science
20:32
@DIRAC1930 yes
I think Jordan and Heisenbeg came up with QFT (which they called wave fields)
@ACuriousMind to what do we owe this groan? :P
@DIRAC1930 he stopped believing in QM cuz he thought it was absurd. and then he started working with Einstein on classical physics
@HerrFeinmann to your brilliantly awful pun :P
But then I think Dirac came up with his quantisation of the electromagnetic field
20:33
@DIRAC1930 i read that Dirac quantised the EM field
@DIRAC1930 what did they do with qft
I didn't really know how to combine it with a honk and I needed to. Guilty as charged.
Einstein criticised Schrodinger's unified field theory. Schrodinger thought he had some big theory
overall, Schrodinger couldn't contribute much outside of the non rel Schrodinger eqn (which was easy to come up with in those days)
I'm sure someone would've come up with the eqn quickly
The SE is probably the most used equation after Newton's second law, today...
Talk about someone who didn't contribute much
people knew that they had to look for a wave equations and people knew de Broglie relations
I think coming up with his wave equation was harder than coming up with Dirac's work on the relation between Poisson brackets and commutators
20:36
Do we really have to be so obsessed with the contributions of individuals from a hundred years ago? None of these people worked in a vacuum or as hermits, the process of science is a collective achievement as much as it lives from individual contributions. What benefit do you hope to gain from making random assertions about which of these people "contributed more"?
@DIRAC1930 hmmm.. I guess it is subjective
i just think that Schrodinger eqn is not that far when u already know u have to look for a wave equations and u know de Broglie hypothesis @DIRAC1930
@ACuriousMind Can we judge Grothendieck then?
Because it is an interesting question and the history is extremely interesting. Its fun to see how these ideas developed by looking through their old papers and reading interviews etc.
Also, schrodinger couldn't physically interpret his equation. Born did it
He enjoyed the hermiting
20:38
@ACuriousMind they worked as Hermite
@Slereah the hermiting was mostly after his main contributions to math, no?
@ACuriousMind Who knows
Maybe his best work is in his crazy shack notebook
@ACuriousMind idk... Schrodinger was also a molester irl... so i like that he didn't contribute too much
maybe that is why i like downplaying him lol
For physics's sake what's the relevance in your discussion?!
@DIRAC1930 I think there is a big difference between discussing the actual history (who did what in which papers, who knew what, etc.) and making judgements of which contribution was "larger" or who is "underrated"
20:40
Scientific proficiency is independent from who you are as a person
for the most part, i don't care about who contributed what to physics
We don't need to judge
physics is a collaborative effort
We can simply let their h-index do it for us
the former I agree is useful and worthwhile, the latter is just a physics version of celebrity cults
20:41
@Slereah no, Feynman has a not so high h-index :P
@RyderRude For someone who believes that you sure love to engage in these discussions about who did what or who was a great physicist.
@ACuriousMind i have repeated the point about there not being any true originators of physics ideas many times in the chat. i believe physics doesn't work in a vacuum
Haag's theorem again, damn it
@HerrFeinmann lol
@HerrFeinmann yes. i am not judging Schrodinger's proficiency based on his personal life. i am judging it objectively
20:43
Citations, h-index, i10-index :
Heisenberg : 71626, 83, 315
Schrodinger : 52926, 80, 219
Einstein : 203131, 157, 823
Dirac : 87670, 70, 112
i just like that he didn't contribute too much. maybe so i don't have to use his name for too many ideas
einstein wins
@RyderRude Stop kidding yourself. Just in this discussion you made a judgement of who was "the greatest physicists of these days" and admitted you have an active interest in downplaying Schrödinger. You only start conceding that this is not the right way to engage with history when you're called out on it.
I think the people you mentioned are given the right credit and they are known in the scientific community for their contribution. There is no such thing as "overrated" or "underrated" for these things, just like there is not for shows. If someone gets a given amount of credit for their work which is under the sunlight, it means that work deserved that much.
Personally I do not mind these discussions but there is one thing that doesn't sit right with me (but it is not an accusation to any of you)
@ACuriousMind to be clear, i do think that some people contribute more than others. but I don't think that there are any true originators of any ideas. thus physics doesn't work in a vacuum. i have said this many times in the chat
20:47
That is, these discussions seems to have the interested to overturn the "established" image of those people. If they are acknowledged as great, then there is the tendency to say they are overrated and vice versa
i realise I have phrased my thoughts in a confusing way
i recognise that some people contribute more than others (but idc about it except for Schrodinger's case maybe lol)
and I recognise that no one truly originates an idea
@Slereah Any idea how accurate these are? Are we trusting that the journals have digitized references in papers from a century ago correctly?
@ACuriousMind It's google scholar's assessment
Google scholar is... probably fine?
I know it's not perfect, some articles missing, some articles duplicated
Even then, we should not compare older authors' h-index to more recent ones, because more time implies more references
They all lived about the same time!
20:54
The ones there yeah
We can't compare to - say - Gellmann, though
@Slereah you just wait until we find some forgotten cache of Soviet papers that cite Heisenberg 20000 times!
@HerrFeinmann *Gell-Mann
@ACuriousMind They're not gonna cite a nazi scientist
they're all citing him to show how wrong he was because he didn't embrace dialectical materialism, obviously
I should try to read more soviet papers
@ACuriousMind he's my rival! :P
So I misspelled his name for years...
20:58
maybe that's why he hates you :P
@Slereah is this physics-only citations
Einstein seems to be much higher than the others here
It's citations on google scholar
Presumably in various other
oh
Einstein rejected quantum theory later in life and went on doing unified field theory
this shows that people's physics tendencies are shaped by their philosophical dispositions. Einstein just couldn't square with non determinism and non realism because of the pre conceptions about the world he grew up with
@RyderRude I feel like people should revisit a lot of this work and other work on UFT by other of his contemporaries. There must be a lot of hidden gems hidden
@RyderRude Bohr was said to be more a philosopher than a physicist
21:06
@DIRAC1930 i think people must have read those papers. they can't just ignore them, especially papers from Einstein. Its just that the ideas are experimentally incorrect
@DIRAC1930 oh
Heisenberg said of Bohr that he was "primarily a philosopher, not a physicist"
I think Bohr also wrote the first paper on the energy-time uncertainty principle and its consequences in rel-qm
Bohr was the first person whom Heisenberg revealed his non-realism ideas to. and bohr forever defended those ideas aggressively
@DIRAC1930 oh
@DIRAC1930 was this before qft
I think it was in 1927 in an article published in Nature but I can't remember the title of the paper
I think it might be this one nature.com/articles/121580a0
21:13
he writes $i$ as $\sqrt {-1}$ :P
pretty cursed
Bohr makes lots of physical arguments
the latter generation of physicists had an easier time accepting quantum theory compared to many in Einstein's generation
it is because paradigm shifts are resisted in society
What are peoples favourite monographs?
i think i haven't read any monographs
perhaps something like Newton's Principia can be called a monograph. i havent read it completely though
@DIRAC1930 it seems like u learn ideas directly from the historical sources
22:17
One gets a deeper and fuller understanding of why something is the way it is that way
Compared to learning a set of working rules
