Usually, "by request" is accompanied by an OTRS ticket number in the edit summary or on Talk. Is there any such thing you could add to the Talk page so folks don't try adding these particular images again? Thanks. --Lexein (talk) 02:22, 10 November 2012 (UTC)

Good point. I have uploaded a new png-version, and made a change to the article on which the image resides. Cheers - DVdm (talk) 07:06, 12 April 2013 (UTC)

(moved)
Dear Mr Ryazanov: I saw your modification to Multivariate normal distribution dated 25/4. You wrote that "^k was missing in normalization factor" but actually the ^k should not be there, since the $$2\pi$$ is inside the determinant, and $$|2\pi\Sigma|=(2\pi)^k|\Sigma|$$, so there's no need for an additional ^k. Hence, I removed it. Cheers. YetAnotherBunny (talk) 14:47, 30 April 2013 (UTC)

Why did you undo the revision 643960041 of SecureDigital? --Txt.file (talk) 13:15, 5 February 2015 (UTC)
 * The link to WP:UNITS included in the edit summary explains what was wrong. Specifically, the unit name "volt" must not be capitalized, and the adjective form must be hyphenated.
 * Regarding  and, I don't really care, although the former is shorter, and  would be more readable (WP:UNITS actually suggests   or , which is the same as ). — Mikhail Ryazanov (talk) 00:07, 6 February 2015 (UTC)

Suggestion
Can we please restart the discussion—my suggestion would be for you to delete your last two comments and my comment, perhaps with an edit summary like "per discussion at my talk". That's just a suggestion because I might not have much that is useful to say because the module essentially emulates what the old templates did, so the original thinking is from years ago. I'm distracted with off-wiki issues at the moment and may not reply for a while. Johnuniq (talk) 06:11, 8 February 2015 (UTC)
 * Done, please go ahead. Of course, it's not urgent, but it would be nice to clarify this issue eventually. — Mikhail Ryazanov (talk) 07:16, 8 February 2015 (UTC)

Being civil
You've been around long enough to know better than to be WP:UNCIVIL, particularly when it concerns WP:ESs: your ES here is not appreciated. Do not make assumptions as to what I do or do not intend to do, therefore please refrain from warning me off by chastising me with "and do not revert other changes". Just as your error as to the alcohol figures were accepted as good faith errors, neither did I notice that you'd changed one word lower in that particular edit. Thank you for your courtesy and understanding. --Iryna Harpy (talk) 05:20, 23 March 2015 (UTC)


 * I sincerely apologize if my summary upset you, I had no intention to do so. If you think that I was "chastising you" because I omitted the word "please", I assure you that it was done only because I thought that it would not fit in the allowed space and I was not considering it that important. The whole "do not revert" part was merely a suggestion, or an appeal, to be more attentive and considerate to other editors' contributions. Namely, my edit included several corrections:
 * replaced the spaced hyphen with the unspaced en dash in the range (MOS:ENDASH),
 * removed the duplicate "%" in the range (MOS:PERCENT),
 * added a comma before "where" (non-restrictive clause),
 * changed "culture is [an] influence" to "culture has [an] influence" (a purely semantic issue, without any implications whether that culture still influences them or not anymore),
 * but you have reverted everything instead of simply correcting one number that I edited wrongly (deleting "5" instead of "0"), so I just wanted to let you know that this was not a good action. — Mikhail Ryazanov (talk) 06:26, 24 March 2015 (UTC)
 * No, you're incorrect. I saw that you'd made a couple of edits and the only revert was this one. The grammar is easily copyedited and, as you can see, I came back to the 'is' business afterwards here. Nevertheless, my apologies for being curt. I'm always careful about explaining as much as possible in the ES. I'm not sure exactly how many characters the summary allows for, but it does allow for around a couple of hundred (now, there's something worth working out).


 * Now, I'll apologise for not going back to fix the – en dash issue, but the article needs another copyedit in order to address grammatical issues which recently arose due to a little edit war between a couple of editors, neither of whom are native English language speakers. Essentially, it needs to be rounded out a little more, and the language tightened in general. Please see the article's talk page regarding that problem.


 * I hope that we can dispense with the animosity. I suspect we've both overreacted to a minor misunderstanding. I can see, by your edit history, that you're a good faith editor... so I hope we can be only friendly terms and work collaboratively in future. Nice to make your acquaintance! --Iryna Harpy (talk) 09:29, 24 March 2015 (UTC)

The unit is Kelvin
Dear Mikhail

I have undone your edit on the article "Arrhenius equation" as the unit is called kelvin (K) not kelvins plural. That is also the case if it is 1 kelvin, 2 kelvin etc.

Regards EvilxFish (talk) 10:51, 26 February 2017 (UTC)


 * Please read Kelvin. — Mikhail Ryazanov (talk) 20:26, 26 February 2017 (UTC)


 * I think you might be right but I need to look into this further, it seems so weird. In my entire career so far I have always said "22 Kelvin" not "22 Kelvins". Will let you know if I want to continue this dispute further EvilxFish (talk) 23:18, 26 February 2017 (UTC)


 * It should be "22 kelvins" — in lowercase and with plural "s". Just like "22 joules", "22 watts", "22 volts" and so on. All style guides and dictionaries are consistent in this respect. — Mikhail Ryazanov (talk) 23:31, 26 February 2017 (UTC)

concentration unit
I am concerned that you have changed concentration units from mol dm-3 to mol/L. What is the justification for this change? I believe it is against IUPAC recommendation Petergans (talk) 10:17, 1 March 2017 (UTC)


 * I don not know what exactly you are referring to, but "mol dm-3" should have been changed to at least "mol dm−3" (see MOS:MINUS). However, I have changed it to "mol/L" ("mole per litre"), since this notation, perfectly acceptable in SI and according to our MOS:NUM, is much cleaner than "mol dm−3" ("mole decimetre reciprocal cubed", or how do you pronounce it?). Moreover, the prefix "deci-" is discouraged by MOS:NUM, and in pedantic SI this would be "kmol/m3". — Mikhail Ryazanov (talk) 22:59, 1 March 2017 (UTC)

Question about Elitzur-Vaidman bomb tester/MZ interferometer
Thanks for your contributions! I hope you can clear this up for me. In regard to the above experiment:

If the bomb is a dud, can there ever be no photon detected at either detector?

In other words, if the bomb is a dud, and the photon remains in its superposition until it reaches the end of both the lower and upper paths and the second half-silvered mirror, can it interfere with itself destructively, resulting in no detection? Or does it always interfere with itself constructively, resulting in a detection at one of the detectors, but never the other one?

Thanks again. Informata ob Iniquitatum (talk) 02:07, 17 August 2017 (UTC)


 * In an ideal experiment the photon must reach one of the detectors, since it cannot be absorbed anywhere else (and the energy is conserved, so it cannot just "disappear").
 * In reality the mirrors are not perfect, so there is a possibility (usually, small) that the photon is absorbed by one of the mirrors and thus does not reach any detector. The detectors are also not perfect, so not every photon absorbed by a detector produces a signal (that is, is "detected" in the experimental sense). And, experimentally, there is no way to make exactly one photon, only the average rate can be controlled, so only the probability of having a given number of photons passing in a given time interval can be known. Thus experiments are always done in terms of statistical measurements, and the analysis takes the non-ideal effects into account. I think, this should be discussed in the experimental articles (I have not read them). — Mikhail Ryazanov (talk) 02:39, 17 August 2017 (UTC)

Google Code-In 2019 is coming - please mentor some documentation tasks!
Hello,

Google Code-In, Google-organized contest in which the Wikimedia Foundation participates, starts in a few weeks. This contest is about taking high school students into the world of opensource. I'm sending you this message because you recently edited a documentation page at the English Wikipedia.

I would like to ask you to take part in Google Code-In as a mentor. That would mean to prepare at least one task (it can be documentation related, or something else - the other categories are Code, Design, Quality Assurance and Outreach) for the participants, and help the student to complete it. Please sign up at the contest page and send us your Google account address to google-code-in-admins@lists.wikimedia.org, so we can invite you in!

From my own experience, Google Code-In can be fun, you can make several new friends, attract new people to your wiki and make them part of your community.

If you have any questions, please let us know at google-code-in-admins@lists.wikimedia.org.

Thank you!

Commas
Comma use varies greatly among and within types of English. The Aberfan article is written in British English, which is less prescriptive than in US English. In BrEng, commas are not needed where you are trying to place them. If you dispute this, please do not edit war on the article, but, per WP:BRD, please use the talk page to discuss. - SchroCat (talk) 08:50, 2 February 2020 (UTC)


 * , these commas are needed in any English. The comma before "which" is requiered, just like in your own second sentence above. The commas before "and" separate independent clauses with different subject-predicate pairs. Otherwise, for example, in "...the tip was saturated and approximately..." the word "approximately" is parsed as connected to "the tip", but actually is connected to "spoil" in the next part. Even if these commas before "and" are not strictly required in BrEng (although the Universities of Bristol and Sussex do not think so), they are not prohibited, and using them helps to avoid "garden-path sentences". So unless you show me a style guide that explicitly forbids them, I'm going to put them back. And if you revert again, your behavior will be reported as disruptive. — Mikhail Ryazanov (talk) 19:18, 2 February 2020 (UTC)
 * Thanks for stating in advance that you'll deliberately edit war with me: per WP:STATUS QUO this should give you enough of a clue as to discuss (as requested), rather than edit war. As already explained, British English is less prescriptive than in colonial English, (and is flexible within BrEng too) - SchroCat (talk) 20:05, 2 February 2020 (UTC)
 * Now the misguided attempt to report me at ANI has fallen flat, perhaps a discussion would be the best approach. As you have agreed above that some of your suggested versions "are not strictly required in BrEng" we can ignore those and only discuss what you think is left? - SchroCat (talk) 22:15, 2 February 2020 (UTC)

Concentration unit
The unit mol dm-3 is pronounced moles per cubic decimetre and there is good reason for preferring this notation. On the molal concentration scale the unit would be mol Kg-1. The notation mol/Kg is not, as far as I know, in common use. Furthermore, the use of / (slash) is potentially ambiguous, whereas "to the power of -3" is not. A further possible ambiguity is mentioned by Skoog et. al, "Analytical Chemistry", 8th edition, p76, '''X is the number of moles.. that is contained in 1L of solution (not 1 L of the solvent)'''. This is because the mol fraction unit of concentration is defined as the number of moles of solute divided by the number of moles of solvent and is determined by weighing. (https://goldbook.iupac.org/terms/view/M03970) Concentration scales are clearly defined in the WP article concentration.

I accept that moles per litre is used in common parlance and that the volumetric flasks and pipettes are marked with litre as unit. However, in theoretical presentations (e.g. Wikipedia) mol dm-3 is preferable because it is unambiguous. Note also that the mass of a given quantity of solution is independent of temperature, whereas its volume is not. That's why volumetric flasks and pipettes have the calibration temperature, usually 25°C, engraved on them. Paradoxically, manufacturers must calibrate flasks and pipettes by weight. Petergans (talk) 09:54, 16 April 2020 (UTC)


 * , I see multiple metrological mistakes here. Please read the SI brochure The International System of Units (the English version starts at p. 117) and, if you wish, Quantities, Units and Symbols in Physical Chemistry, about quantities, dimensions and units. Some key points:
 * The expressions $$a/b$$, $$\frac{a}{b}$$, $$a\,b^{-1}$$ and $$b^{-1}\,a$$ are completely equivalent. The choice between them is merely a matter of convenience.
 * 1 L is completely equivalent to 1 dm3. By definition.
 * Exactly what is divided by what is determined by the quantity definition. For example, $$\frac{n_\text{solute}}{V_\text{solvent}}$$, $$\frac{n_\text{solute}}{V_\text{solution}}$$, $$\frac{n_\text{solvent}}{V_\text{solute}}$$ and $$\frac{\rho_\text{solvent}}{M_\text{solvent}}$$ (here n is amount of substance, V is volume, M is molar mass, ρ is density) are different quantities, but they all have the same dimension $$\frac{\textsf{N}}{\textsf{L}^3} = \textsf{N}\,\textsf{L}^{-3}$$ and all can be expressed in $$\frac{\text{mol}}{\text{L}}$$ or $$\frac{\text{mol}}{\text{m}^3}$$, also written as $$\text{mol}\;\text{m}^{-3}$$ or $$\text{m}^{-3}\,\text{mol}$$, and other units with the same dimension. There is no way to distinguish such quantities by the form in which their units are written, and no particular units in any particular form are less or more ambiguous that any other.
 * Surely, "mol Kg-1" and "mol/Kg" are not used. Because the correct unit is "mol kg−1" = "mol/kg", which is commonly used for molality.
 * Weight and mass are very different quantities and are not interchangeable. The same mass has different weights in different places on Earth and at different ambient pressures, depending on the substance/object density. For example, helium in a balloon has a negative weight (but a positive mass, of course).
 * Negative values must be indicated by the minus sign (−), not by the hyphen (-). See MOS:MINUS. Thus helium-3 (hyphen), but to the power of −3 and dm−3 (minus), not to the power of -3 and dm-3.
 * So, "mol/L" and "mol dm−3" are exactly the same unit written in different forms. And among these forms, "mol/L" is more convenient because it is easier to read and pronounce and much easier to type (even you cannot type "mol dm−3" correctly). Moreover, it looks the same in plain text (without formatting) and can be easily copy-pasted without any problems, whereas "mol dm−3" is much more problematic in this respect.
 * Besides that, you have again . First, without reaching a consensus. Second, reverting even those punctuation, stylistic and formatting edits that were not related to the units issue. This is not acceptable. Please undo your incorrect rollback (you can change "mol/L" back to "mol dm−3" for now, if you wish) and continue this discussion. — Mikhail Ryazanov (talk) 21:55, 16 April 2020 (UTC)


 * Your condescending tone is offensive; that is why I prefer to keep this discussion on your talk page. I don't need any lectures on chemical principles. I was a lecturer in chemistry at Leeds University for 39 years and am fully conversant with the issues. What are your credentials regarding chemistry?


 * You have not presented any compelling reason for making the changes that you propose regarding the unit of concentration. I suggest that the unit mol dm-3 is to be preferred because dm is a primary SI unit and L is not.


 * It is preferable that the same conventions are used in all Wikipedia articles where a concentration unit is specified. So, if the convention is changed in this article it must also be changed in many other articles. Petergans (talk) 08:48, 17 April 2020 (UTC)


 * , I have enough competence to see the obvious mistakes that I have described above.
 * I can repeat that the coherent SI unit is mol/m3, see table 5 on p. 139 in the SI brochure. Its multiple corresponding to mol/L is kmol/m3. Writing it as mol dm−3 is like writing m ms−1 instead of km/s. And again, the prefix deci- is discouraged here: ("decimeter" is not among the exceptions, but notice "hectolitre" there).
 * The IUPAC recommendations also say that the concentration and solubility SI unit is mol/m3, as can be seen in the table on p. 48. Notice also the footnote there: This demonstrates that "mol L−1" and "mol dm−3" are the same unit and says nothing about discouraging litres or demanding using cubic decimetres instead.
 * And once again, dm-3 violates MOS:MINUS:
 * Regarding changing the conventions in many other articles, mol/L or mol L−1 is currectly used in  133 arctiles, whereas mol/dm3 or mol dm−3 only in 24 arctiles (which I have already mentioned and explained).
 * Last but not least, I again ask you to return my edits not related to this units issue, which you have incorrectly without any justification. The rules clearly say:  So even if you don't like my changes of the units to "mol/L", this is not a valid reason to revert everything else, especially since the units were a minor part of my edits there. — Mikhail Ryazanov (talk) 02:59, 18 April 2020 (UTC)


 * I do not question your competence. The issue arises from an apparent lack of experience in the field of stability constants. The discussion on this page of WP shows that there is no compelling reason for preferring one convention over the other on theoretical grounds. In terms of practise, the software listed at http://www.hyperquad.co.uk/, which I have developed, is cited in more than 1000 publications. It uses the mol dm-3 convention. That is why I have used it in WP.


 * By all means make improvements to the article, but please leave the units issue alone. Petergans (talk) 07:30, 18 April 2020 (UTC)

Hoosier cabinet
Hello Mikhail Ryazanov - thank you for your contributions to Hoosier cabinet. I noticed you are adding a period "." to the end of Harvard citations. Is this something new that I should know about? The Wikipedia citation templates examples do not have the "." period. The Template:Harvard citation documentation has examples with periods and examples without periods. Just curious, TwoScars (talk) 20:16, 15 August 2020 (UTC)
 * Harvard templates can be used within text, thus they do not produce periods by themselves. However, entries in Footnotes/Citations/References should end with periods. Most templates for endnotes do produce them, but when using other templates or explicit formatting, these periods should be added manually in order to keep the section format consistent. — Mikhail Ryazanov (talk) 20:42, 15 August 2020 (UTC)

A theme
It appears to be a theme in your editing that you have a high degree of confidence in imaginary rules. For example: the OED includes "commercial" being used as a synonym of "TV or radio advertisement" beginning more than 85 years ago: 1935  Fortune Nov. 193   We used no media other than radio to feature this soup..using one-third of our commercials on Campbell's Chicken Soup. 1936  Variety 24 June 55/2   Commercials are restricted to 190 words on an hour program. ... Though at one point it was restricted to the United States, this nominal usage of the word is widespread and, I suspect, understandable by native speakers of any major variety of English. The phrase "television commercial" sounds completely natural to this native AmEng speaker, while "television advertisement" sounds slightly stilted. I bring this to your attention in the hope that you will reflect on what has led you to repeatedly make confident but insupportable assertions about word usage, and adjust your approach accordingly. --JBL (talk) 14:37, 28 May 2021 (UTC)
 * WP:FOLLOWING? ­— Mikhail Ryazanov (talk) 16:56, 28 May 2021 (UTC)
 * Yes, it's a good link; have you read it? Correct use of an editor's history includes (but is not limited to) fixing unambiguous errors ... or correcting related problems on multiple articles.  --JBL (talk) 17:56, 28 May 2021 (UTC)
 * As we have seen, these "unambiguous errors" were not "unambiguous" and not "errors" at all. I personally consider your behavior towards me inappropriate, and several other people on the Language desk gave similar hints to you.
 * Regarding this particular issue, the word "commercial" in the meaning "advertisement" is merely professional jargon that has entered general informal usage. It is not encyclopedic, so WP (like other encyclopedias and serious documents) has, for example, articles "Television advertisement" and "TV advertisements by country" rather than "... commercials", and there is no reason to deviate from this terminology in other WP articles. — Mikhail Ryazanov (talk) 18:42, 28 May 2021 (UTC)
 * No, you are definitely making unambiguous errors; that you don't acknowledge them does not make them less erroneous. (As an example, on the topic of what people on the reference desk say, have you noticed several of them explicitly tell you that I am correct about your choice of venue?)  Your level of confidence is out of proportion to your level of expertise; I ask only that you engage in sufficient self-reflection to adjust the former to match the latter.  I am genuinely not interested in hounding or harassing you, so I will desist from posting here unless you request that I address something in particular. --JBL (talk) 20:02, 28 May 2021 (UTC)
 * As I've in the Language desk discussion and explained in the  that you have just reverted, I want to clarify some issues for myself before starting the discussion on that article talk page. Since you were studying my edit history, you could have noticed that I was making similar edits many times before in many WP articles, but you are the first person who dislikes them to the point of aggressively reverting with, politely saying, unhelpful arguments. And thus, since discussing all these edits on the corresponding article pages would be strange, I've asked for clarifications on the reference desks. (By the way, whom do you mean by "several of them explicitly tell[ing me]"? I see only that one editor replied to you twice, supporting my decision.) I'm sorry, but your whole last reply confirms my sad observation that your statements only reflect your own opinion, in a rather rude tone, unsupported by any objective arguments. However, since I do want to reach some consensus, I don't even think of forbidding you from replying to me here or anywhere else, and only ask you again to be polite, considerate and constructive. — Mikhail Ryazanov (talk) 21:06, 28 May 2021 (UTC)
 * To answer your direct question: there are two explicit comments directing you to the article talk page, from Jack of Oz (the very first response to you), from me, and from the IP editor. (I mis-remembered Trovatore's comment as specifying the correct location of discussion, so "several" is an overstatement; "multiple" would have been more accurate.) --JBL (talk) 21:22, 28 May 2021 (UTC)
 * Jack of Oz said literally (my emphasis): "would have contested those reversions by reverting them myself. If the first reverter persisted, I'd have gone to the talk page and explained my reasoning." Since I wasn't going to enter an edit war by reverting your last reverts, the time for the talk page simply has not come yet. No indication that my question on the ref desk was misplaced at that time. The "IP editor" had some general remarks (replying to you) that "who is interested in an article will [notice the discussion on its talk page]". I totally agree with this idea, but again, there were no indications that I shouldn't have asked my questions on the ref desk. "The response is then fed back into the talkpage discussion" is exactly what I eventually want to do. I can repeat for you one more time: when I'm ready to return to that article, I'm going to discuss your reverts on the article talk page, but before that let me clarify some issues for myself wherever I see appropriate. — Mikhail Ryazanov (talk) 21:54, 28 May 2021 (UTC)
 * At this point we have passed the boundary where dishonesty and incompetence blur together, so I withdraw. Happy editing; please don't mess with any more math articles. -JBL (talk) 22:01, 28 May 2021 (UTC)

Knudsen mean free path
Hey Mr. Ryazanov, I edited the formula you originally put up for the mean free path on the Knudsen number page. It had density where pressure should be, with density one does nog get a length looking at the dimensions, furthermore the cited source also gives the formula with pressure. However, I have not edited the surrounding formula's as it is unclear to me how they derive to the correct formula for the mean free path. Maybe you want to have a look yourself or explain what you were going for. Thanks in advance.DawsonRyder (talk) 19:13, 20 October 2021 (UTC)
 * It would be kind to provide links to the changes you're discussing or at least to the article under question. I guess, you mean the article "Knudsen number", but the last time I've edited it was more than 2 years ago, so I don't even remeber this fact, let alone the details. Now I was able to reconstruct that my was purely stylistic, whereas the formula itself (with the density instead of the pressure) was already there long before me,  in 2009 by some anonymous editor; I just haven't paid attention that it was wrong. So thanks for correcting it, but I don't really understand why you are addressing me instead of the original author or any other editor of that page... — Mikhail Ryazanov (talk) 20:39, 20 October 2021 (UTC)

In May 2021 you added

double-{DISPLAYTITLE:α-Ketoglutaric acid}-doubled

to the article on Α-Ketoglutaric acid. This produced exactly the result I would have wanted if I had been editing the page. I would like to do the same thing to hundreds of articles on enzymes that use Α or a or alpha rather than α. When I try, however, it doesn't work. for example, if I add

double-{DISPLAYTITLE:α-Amylose}-doubled

to Alpha-amylase it says


 * Warning: Display title "α-Amylose" was ignored since it is not equivalent to the page's actual title.

I've also tried using the Move function, but that (in many attempts) is similarly rejected.

Sorry to bother you with this, but as you've succeeded where I've failed you may have a suggestion. Incidentally I've tried various suggestions from experts on the general problem, but nothing has worked. Athel cb (talk) 14:30, 27 June 2023 (UTC)
 * as I understand, the "page's actual title" must indeed match, that is, be "Α-Amylose" (with the capital Greek "Α" as the very first letter). That page, however, already exists as a redirect to "Alpha-amylase", thus the "Move" fails. So you'll first need to make a rename request, as described in the move error message (it can be done as a "technical" request), and after that happens, the "DISPLAYTITLE" should work. Hopefully... — Mikhail Ryazanov (talk) 16:17, 27 June 2023 (UTC)

GPCR schematic
Thank you for your helpful schematic showing helix position changes of GPCRs upon activation! I have noticed an error in it: the bottom panel is labelled as being an intracellular perspective, however the anti-clockwise order of the helices (1-7) as depicted would be the result of an extracellular perspective. The source material you have cited has a figure (3b) that is labelled as an extracellular view. I have edited the caption on the GPCR page.

In short the labelling is incorrect and should read extracellular, OR (better) the image should be flipped so that the arrangement of the helices does reflect an intracellular view.

I am happy to make changes to the images if you have a vector version to share. Drtmantis (talk) 11:06, 3 November 2023 (UTC)
 * I can't recognize which image and page you're talking about. Please provide corresponding links. — Mikhail Ryazanov (talk) 00:55, 4 November 2023 (UTC)
 * Sorry Mikhail, I have addressed the wrong account. Please remove the topic as you like. Drtmantis (talk) 12:22, 6 November 2023 (UTC)

List of publications by John B. Goodenough
Dear Mikhail Ryazanov: On 2024-06-11T08:08:44‎ Mikhail Ryazanov deleted List of publications by John B. Goodenough, \\talk contribs‎ m  41,597 bytes −224,070‎  →‎Works: MOS:CAPS, WP:NOTDATABASE (unformatted data dump isn't needed at all) \\ which I originally placed into John B. Goodenough article, and later another user made a separate article for this list. I would like to draw your attention to couple points: 1) You wrote "unformatted" - this is incorrect. My references were formatted using EndNote. 2) There are other Publications Lists on Wikipedia, e.g. List of publications by Ottaviano Petrucci Although, I understand the justification for the WP:NOTDATABASE policy, I feel that this policy is not applied consistently, and that you singled out Goodenough's list among others. I also want to remind both of us, that another user moved my list to a separate article (after receiving my approval). Did you delete, that article too? Walter Tau (talk) 08:44, 21 July 2024 (UTC)

List of publications by John B. Goodenough
Dear Mikhail: thank you for pointing out the WP:NOTDATABASE policy. I was not aware of it. However, as I just found out, there is a better way to present a Publications' List in wikipedia. The List can be placed into wiki-data, and a link to wiki-data can be provided in the wiki-article. if you have experience with wikidata, could you please do it? I learned about the existence of wikidata only today, and it will take me some time to learn how to make such wikidata. Thank you in advance, WT Walter Tau (talk) 09:45, 21 July 2024 (UTC)
