Hello, Bernanke's Crossbow and a belated welcome to Wikipedia! I see that you've already been around awhile and wanted to thank you for your contributions. Though you seem to have been successful in finding your way around, you may benefit from following some of the links below, which help one get the most out of Wikipedia. If you have any questions, you can ask me on my talk page, or place {{helpme}} on your talk page and ask your question there. Please remember to sign your name on talk pages by clicking or by typing four tildes "~~~~"; this will automatically produce your name and the date. If you are interested in learning more about contributing, you might want to consider being "adopted" by a more experienced editor or joining a WikiProject to collaborate with others in creating and improving articles of your interest. Click here for a directory of all the WikiProjects. Finally, please do your best to always fill in the edit summary field. Happy editing! Red Director (talk) 17:57, 4 April 2019 (UTC)[reply]
I was looking at my talk page archive today, and realised I never responded to the question you asked here. It looks like although the edit you highlighted introduced a new ref by the name of "Greenwood", which I hadn't defined at that point, I corrected the error with my next edit, after you has asked me about the matter, by providing the details of the reference. So the current version of the article has no problem in that regard. I hope that answers your query! Thanks, and happy editing. — Amakuru (talk) 22:49, 28 April 2019 (UTC)[reply]

Hello, Bernanke's Crossbow. It has been over six months since you last edited the Articles for Creation submission or Draft page you started, "Thrust".
In accordance with our policy that Wikipedia is not for the indefinite hosting of material deemed unsuitable for the encyclopedia mainspace, the draft has been nominated for deletion. If you plan on working on it further, or editing it to address the issues raised if it was declined, simply edit the submission and remove the {{db-afc}}, {{db-draft}}, or {{db-g13}} code.
If your submission has already been deleted by the time you get there, and you wish to retrieve it, you can request its undeletion by following the instructions at this link. An administrator will, in most cases, restore the submission so you can continue to work on it.
@Smokefoot: Sure; if you think those would be a better name for the template, feel free to edit it. IMHO, the philosophical boundary between cyclopentadiene complexes and their cyclopentadienyl and cyclopentadienide analogues is super thin/porous — it depends on the (somewhat) theoretical abstractions of "what is the oxidation state of this covalently-bonded metal?" and "is the ligand-metal bond a full electron transfer or not?" But I'm not a chemist, and I recognize that the community seems to think these sorts of distinctions are useful, so I might have screwed up in distinguishing them in some instances. Bernanke's Crossbow (talk) 23:34, 9 May 2022 (UTC)[reply]
Clearly not a chemist, but not too shabby with verbal acrobatics. Cyclopentadiene has six H's vs cyclopentadienyl or cyclopentadienide, which have five H's. Cyclopentadienyl vs cyclopentadienide falls more into you "theoretical abstractions" category. Happy editing. There's lots to do in the chemistry project even if you are not a chemist's chemist. --Smokefoot (talk) 23:49, 9 May 2022 (UTC)[reply]
I wanted to personally thank you for the updates you are doing to the Sequential space article. In my mind the previous version of the article had become overly technical and bogged down with duplication and minutiae. The new contents is more readable, focusing on the essential and following a more encyclopedic style with references to outside sources instead of trying to spell out every single detail that one could think of. Thank you! PatrickR2 (talk) 22:57, 28 June 2022 (UTC)[reply]
Hi Bernanke's Crossbow.
I've noticed that you've change changing a lot of LaTeX code (i.e. <math></math>) into Unicode. This is discouraged in Wikipedia for WP:ACCESSIBILITY reasons. Specifically, some readers may be using browsers that either don't render certain Unicode (such as arrows → or ∈ ) or don't render it correctly. In addition, some Unicode characters might not be interpreted correctly by some screen readers. Here are some relevant quotes:
MOS:BBB - "A particular concern for the use of blackboard bold on Wikipedia is that the Unicode symbols for blackboard bold characters are not supported by all systems, or that font substitution on browsers often render these symbols in discordant fonts. The use of Unicode characters for blackboard bold is discouraged in English Wikipedia. Instead, the LaTeX rendering (for example <math>\mathbb{Z}</math> or <math>\Z</math>) or the standard boldface must be used."
The disadvantages of {{math}} are the following:
not all formulas can be displayed. While it is possible to render a complicated formula with {{math}}, it is often poorly rendered. Except for the most common ones, the rendering of non-alphanumeric Unicode symbols is often very poor and may depend on the browser configuration (misalignment, wrong size, ...). The spaces inside formulas are not managed automatically, and thus need some expertise for being rendered correctly. Except for short formulas, there are much more characters to type for entering a formula, and the source is more difficult to read.
Use of {{mvar}} and {{math}} for isolated variables and very simple inline formulas
Use of LaTeX for displayed formulas and more complicated inline formulas
Use of LaTeX for formulas involving symbols that are not regularly rendered in Unicode (see MOS:BBB)
Avoid formulas in section headings, and when this is a problem, use raw HTML (see Finite field for an example)
And some more guidelines
MOS:FORMULA - "For a formula on its own line the preferred formatting is the LaTeX markup, with a possible exception for simple strings of Latin letters, digits, common punctuation marks, and arithmetical operators."
MOS:FORMULA - "Even for simple formulae the LaTeX markup might be preferred if required for uniformity within an article. For readability, it is also strongly preferred not to mix HTML and LaTeX markup in the same expression."
MOS:MATH#PUNC - "If the formula is written in LaTeX, that is, surrounded by the <math> and </math> tags, then the punctuation should also be inside the tags, because otherwise the punctuation could wrap to a new line if the formula is at the edge of the browser window."
MOS:NOTED - "avoid contentless clichés as Note that, It should be noted that, It must be mentioned that, It must be emphasized that, Consider that, and We see that." "Avoid, as far as possible, useless phrases such as: It is easily seen that ..., Clearly ..., Obviously ..."
MOS:MATH#TONE - "Articles should avoid common blackboard abbreviations such as wrt (with respect to), wlog (without loss of generality), and iff (if and only if), as well as quantifier symbols ∀ and ∃ instead of for all and there exists." Also avoid abbreviations like "iff", "i.e.", "e.g.", "resp." (spell them out instead: "if and only if", "that is", "for example", "respectively").
This is a giant mass of text. For some of it, the relevance to my work is unclear. (When do I "use Unicode characters as icons"? Heck, when do I use anything as icons?)
I have a strong preference for {{math}} in inline text, for many of the reasons listed in WP:Rendering math#Pros of HTML. Also, {{math}} simplifies proper punctuation formatting relative to <math>. I rarely find that preference outweighed by uniformity.
In general, I think that my use of {{math}} comports with common practices here. I diverge at blackboard bold, which I think the guidelines over-dissuade. Neither LaTeX nor HTML substantially simplifies screen readers' job, and most browsers can reproduce all symbols, including blackboard bold, just fine. The problem is that browsers recognize HTML character entities inconsistently. For example, some browser systems recognize ℝ, ℝ, or ÓD; as ℝ inconsistently at best — but the direct character code (as earlier in this paragraph) almost always displays fine.
Wikipedia has, in general, maintained a nice balance between inline formulas in HTML and block display formulas in LaTeX until the past few years, when it has started to trend away from HTML formulas. I'd like to see that trend reversed, if possible.
I don't edit articles solely to convert LaTeX to HTML (not that you claimed I did). When I'm editing the text of a paragraph, I make sure the punctuation is formatted correctly. MOS:MATH#PUNC doesn't emphasize the correct way to punctuate LaTeX equations[1] as much as it ought, so I often find myself needing to adjust the inline equations. And if already I'm adjusting the inline equation, well...it seems apropos to write it using the formatting I prefer.
On 26 September 2022, Did you know was updated with a fact from the article Subgroup distortion, which you recently created, substantially expanded, or brought to good article status. The fact was ... that subgroup distortion theory, introduced by Misha Gromov in 1993, can help encode text? The nomination discussion and review may be seen at Template:Did you know nominations/Subgroup distortion. You are welcome to check how many pageviews the nominated article or articles got while on the front page (here's how, Subgroup distortion), and if they received a combined total of at least 416.7 views per hour (i.e., 5,000 views in 12 hours or 10,000 in 24), the hook may be added to the statistics page. Finally, if you know of an interesting fact from another recently created article, then please feel free to suggest it on the Did you know talk page.
You recently added a redlink to Exeter Theatre Royal fire about the play that was being performed, in order to spur its creation. Whilst another editor reverted, I thought the underlying idea was right, so I have now created the outline of the article at The Romany Rye (play), if it is of any passing interest. With thanks.

Hi. I wanted to thank you on having started some cleanup of Quotient space (topology). (hope you don't mind, I just did some further cleanup in the Definition section.) The version before your changes was just full of ramblings. It was again a case of editor Mgkrupa going on an editing spree (back in 2021, 2022) and adding all kinds of minutiae not central to the topic at hand and saying the same thing in a multitude of ways to the point that one can't see the forest for the trees anymore. He did not understand that this encyclopedia is not meant to "teach" (see WP:NOTTEXTBOOK item 6 for example). For background info, there was some backlash at some point and he has improved since. But it still annoys me when I need to wade through all that (there are articles of his a lot worse than this one). Anyway, sorry for the rant and thanks for the editing. PatrickR2 (talk) 05:03, 8 June 2023 (UTC)[reply]
No problem on both ends, and many thanks for continuing the work; I had to restrain myself from fixing more duplication because I needed to prepare for a meeting with my advisor soon. I feel much the same way about MgKrupa, except that I'm not really sure it's a case of NOTTEXTBOOK. I feel awkward bad-mouthing another editor behind his back in public (especially since I think he did make some positive changes on a few articles), so I'll forbear from commenting further. But yeah, I'm glad I'm not the only one cleaning up his carnage here and there. Bernanke's Crossbow (talk) 05:16, 8 June 2023 (UTC)[reply]
The situation with CuS is complicated, otherwise you would be correct to call it cupric sulfide. But the compound is mixed valence with some S-S bonds. As I recall. Its a little like FeS2 not being Fe(IV) but Fe++, S2 2-. Of course if you talk to a physicsy person, they even dispute assigning oxidation states to such highly covalent (semiconducting, glistening) materials. Cu2S is more cuprous as you indicated. Figured you might be interested. Cheers, --Smokefoot (talk) 02:40, 3 August 2023 (UTC)[reply]
@Smokefoot: Yes, I suppose I am curious to know that.
Separately, I do think the formulas on Copper sulfide should be link to the pages currently titled Copper monosulfide and Copper(I) sulfide, whether or not the latter nomenclature is accurate. Is linking to those titles OK, or are there particular redirects you would rather I use?
Congratulations, and thank you for helping expand the scope of Wikipedia! We hope you will continue making quality contributions.

As is written at Norm (mathematics)#In abstract algebra, the statement that -th root of a field norm is a norm in the sense of the article (assuming the concept makes sense) is not clear.

Reductive amination
For someone outside of organic chemistry, these articles look similar but to an organic chemist, they are distinct. Reductive amination especially is a well defined topic separate from imine reduction, at least IMHO. This kind of dramatic reorg should be discussed prior to executing. I am all for merging and simplifying, but not in this case. --Smokefoot (talk) 12:48, 13 November 2023 (UTC)[reply]
Most of the current reductive amination page content discusses imine reduction but neither the nitrogenous precursor nor nitrile alternatives.
Consequently that content couldshould move to the hypothetical unified imine reduction page.
Once a page on imine reduction exists, the page on reductive amination needn't include the material on imine reduction in great detail; in can "incorporate it by reference" (as the saying goes) by linking to the unified imine reduction page.
I could say a lot but, the main thing is that these move-merge actions require consultation with our colleagues.
Additional comments and opinions:
Hydrogenation of carbon-nitrogen double bonds is awful. The author, a fetishist organic grad student, wrote many articles that I have been chipping away at for years. His refs are narrow and the artwork is inferior. But, he writes facts, and narrow facts are one of the great impediments to establishing an encyclopedic overview.
I recommend that reductive amination be left alone. Its a super well developed and useful. But you can put the article to a vote.
@Smokefoot: Thanks for the advice. Just two more quick points of agreement:
I was ambiguous above. I too agree that nitrile reduction should be left alone; I just meant it as a model for a hypothetical "imine reduction" page (which I'll put to a vote when I get a chance).
"Hydrogenation of carbon-nitrogen double bonds is awful." is the genesis of this whole shambles.
Your recent article submission to Articles for Creation has been reviewed. Unfortunately, it has not been accepted at this time. The reasons left by DoubleGrazing were:
This draft's references do not show that the subject qualifies for a Wikipedia article. In summary, the draft needs multiple published sources that are:
in-depth (not just brief mentions about the subject or routine announcements)
Make sure you add references that meet all four of these criteria before resubmitting. Learn about mistakes to avoid when addressing this issue. If no additional references exist, the subject is not suitable for Wikipedia.
The comment the reviewer left was:
Could be notable, but needs more sources meeting the WP:GNG standard. The WordPress blog is not considered RS.
Please check the submission for any additional comments left by the reviewer. You are encouraged to edit the submission to address the issues raised and resubmit after they have been resolved.
If you would like to continue working on the submission, go to Draft:Campbell 66 Express and click on the "Edit" tab at the top of the window.
If you do not edit your draft in the next 6 months, it will be considered abandoned and may be deleted.

Normal Values for the Henderson - Hasselbach equation
I don’t think it was clear that 24 and 40 are typical average numbers for bicarbonate and pCO2 at sea level. Actually the blood gas machine measures pH and pCO2 and then calculates a bicarbonate value using the Henderson–Hasselbalch equation. Reknihtdivad (talk) 19:54, 27 April 2024 (UTC)[reply]
I did not agree that the numbers are pulled "out of nowhere". There was a statement that "Adding the other normal values, we get" but that didn't seem clear.
I think the statement I added clarifies where these numbers come from.
When I did the revert I meant to add a comment and expected that clicking the publish button would pop up a comment window. I explained the rational on the subsequent edit which did pup up the comment window. I guess the revert is not actually attached to the revert itself which was not my intent.
I think the typical numbers would be familiar to clinicians and nicely illustrate the use of the equation. I like it that way but that is just my opinion. I am interest in what others have to say. Reknihtdivad (talk) 22:11, 27 April 2024 (UTC)[reply]
In general, I tend to look askance at WP:EXAMPLES in WP pages whose primary WP:TOPIC is not math, philosophy, or law, because otherwise articles on applied science tend to degenerate into a WP:TEXTBOOK-like set of worked problems (see especially my first link). I freely admit that I may remove examples to excess; WP:TEXTBOOK notes that "examples intended to inform rather than to instruct may be appropriate for inclusion in Wikipedia articles."
I think that if "the blood gas machine measures pH and pCO2 and then calculates a bicarbonate value", then
the sample computation ought to have information flowing in the same direction. That is, the computation should determine a bicarbonate concentration from pH and pCO2 values.
I think a statement in the article that is as you say "the blood gas machine measures pH and pCO2 and then calculates a bicarbonate value" is a good idea. The rearranged equation would be in an unusual form. Most people would recognize the Henderson - Hasselback equation in its usual form. Clinicians, doctors, nurses and respiratory therapists are always handed all three numbers to them and don't use the equation. Reknihtdivad (talk) 01:34, 28 April 2024 (UTC)[reply]
You obviously do a lot for Wikipedia and I am glad that you do. Keep it up.
Also some people might think that this is a medical article and should only be edited by those with medical credentials of some sort. I don’t think so at all. I am glad to see someone with an interest in math and chemistry in this. Keep it up. Reknihtdivad (talk) 12:03, 28 April 2024 (UTC)[reply]
@Emmdas07: I have adjusted the article following our seeming concurrence detailed above. The partial pressure and concentration values ought to have units given, but I don't know what they should be, so the numbers are unitless right now. Bernanke's Crossbow (talk) 17:52, 28 April 2024 (UTC)[reply]
The numbers for PaCO2 are in millimeters of mercury (mmHg), I guess probably kPa in Europe. By the way, PaCO2 with little a is for arterial blood and PACO2 written with a capital A is used for Alveolar PACO2.
HCO3- is milliequivalents per liter (mEq/L)
The pH is the negative logarithm of the hydrogen ion concentration in moles per liter.
Clinicians tend to throw these numbers around without using units but I think you are right in an article like this they should be given.
The normal numbers are usually reported as a range like 35–45 mmHg for arterial PCO2 because some variation around the mean is of course normal. The Wikipedia article on arterial blood gasses https://en.wikipedia.org/wiki/Arterial_blood_gas_test is an excellent reference. There is a table it it labeled "Pathophysiology sample values" which shows just single numbers, HCO3− = 24 paCO2 = 40 paO2 = 95 pH = 7.40.

Thanks for your contributions to Berkelium oxide. Unfortunately, I do not think it is ready for publishing at this time because it has no sources.
I have converted your article to a draft which you can improve, undisturbed for a while.
I know that the articles are formally labeled WP:SIAs, not DABs. I am simply following standard on-Wiki practice for inorganic chemistry navigational aids; see, for example, sulfur oxide, lead fluoride, or vanadium chloride.
(Organic chemistry does not appear to follow the same practices, which makes your draftification of chlorophenyl azide much more defensible. Butanol, dihydroxybenzenes, or hexene do all include a few citations and a notional overview of the subject. I think that practice is a mistake, but it may have consensus.)
I reverted the draftification of the two pages, and left a comment on JoeNMLC's talk page, before I found this comment. Just mentioning here that I did so. Hey man im josh (talk) 17:59, 6 May 2024 (UTC)[reply]

Hi Bernanke's Crossbow, please try not to use {{Math}} template in chemistry pages unless it is essential.

Thank you for your edit at Finite model theory! Do you happen to have a page number where Ebbinghaus and Flum make the assertion that all the incongruence with classical model theory follow from Trakthenbrot's theorem? Felix QW (talk) 22:35, 7 November 2024 (UTC)[reply]
Not off-hand. TBH I just copied the cite from Trakhtenbrot's theorem. But since you asked nicely 😉, I just looked it up in the 2nd edition (and modified the cite to match).
§3.5 (p. 62) says: "[I]n the finite [situation] the compactness theorem for first-order logic fails and we shall see in Chapter 7 that there is no sound and complete proof calculus. These facts raise the question whether and why first-order logic can serve as a useful means for the investigation of finite structures....as other central methods of classical model theory (such as the use of ultraproducts or saturated structures) become useless". Then §7.2.1 is about Trakhtenbrot's theorem (alternatively transliterated as "Trahtenbrot"); that section's final paragraph (p. 129) discusses the uselessness of any proof calculus.
Hello! Voting in the 2024 Arbitration Committee elections is now open until 23:59 (UTC) on Monday, 2 December 2024. All eligible users are allowed to vote. Users with alternate accounts may only vote once.
The Arbitration Committee is the panel of editors responsible for conducting the Wikipedia arbitration process. It has the authority to impose binding solutions to disputes between editors, primarily for serious conduct disputes the community has been unable to resolve. This includes the authority to impose site bans, topic bans, editing restrictions, and other measures needed to maintain our editing environment. The arbitration policy describes the Committee's roles and responsibilities in greater detail.
@Smokefoot: As I'm sure you know, WP considers Tumblrs self-published sources, such that they are RSes if the poster is a subject-matter expert. Is the particular guy I cited a bunch a subject-matter expert? Maybe not; I can't tell if he finished graduate school (to be fair, neither did I), and he certainly doesn't have too many publications. I'm also enough of an WP:INCLUSIONIST that I'd rather include his information and search/wait for a better citation than ignore his postings altogether. Such inclusionism can be overdone, sure. But I tried to only include information that seemed taken from a non-WP src and relatively reliable.
In any case, I'd appreciate it if you attempted to argue on substantive grounds like the counterarguments I discussed above, rather than blithely citing WP:RS to an experienced editor. Bernanke's Crossbow (talk) 19:13, 13 January 2025 (UTC)[reply]
All nice comments and being an inclusionist sounds laudable. Thank you. To double down: we are engaged in a business of reliable sources, and I just do not think that social media are acceptable, ordinarily. I saw the image of phenacyl bromide]], uninformative photo of some flask with some crystals. And the photos the sep funnel for some lumiphore was pretty, but I think we need to do better in terms of authentication and credentials.
