==Problems with the "problem list" theory== |
|||
I've just read the 2002 paper by Eleanor Robson, after reading this Wikipedia article. There are a couple things that don't make sense to me. Supposedly this is a list of "teacher's notes" for solving <math>x-1/x=c</math>, with the second and third columns being <math>(x-1/x)/2</math> and <math>(x+1/x)/2</math> respectively. But that's usually not the case. Take a look at the first row. We should have <math>(x-1/x)/2=119/120</math> and <math>(x+1/x)/2=169/120,</math> rather than just 119 and 169. Obviously if you subtract 119 from 169 you don't get the reciprocal of their sum. So how does this help the teacher in any way? |
|||
== Repeat backdoor merge proposal == |
|||
(Row 11 does work if you interpret 45 as 45/60 and 75 as 75/60. But that's the only row that can be made to work by "shifting the sexigesimal point".) |
|||
Please see [[Wikipedia:Articles for deletion/Si.427]] where (again) a merge has been proposed, and contribute if you have an opinion. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein|talk]]) 16:45, 4 November 2021 (UTC) |
|||
Secondly, if this is just a series of exercises, then why are the angles of the triangles spaced out by about 1°? There are many other examples that could have been used, based on similarly sized sexigesimal numbers, but they weren't used. |
|||
:Front door actually, I linked it back to the discussion here. Merging as an alternative to deletion is a normal option.[[User:Selfstudier|Selfstudier]] ([[User talk:Selfstudier|talk]]) 16:58, 4 November 2021 (UTC) |
|||
:Note added later: I checked, and actually if you limit the range to the range of the tablet and use for X numerators and denominators that are [[regular number]]s up to 125, then the Plimpton 322 tablet gives all of them except one, namely X=125/64. This should go between rows 11 and 12. I think it's pretty impressive. I used a spreadsheet, but the author didn't have Excel.

::My position, which I have expressed repeatedly in many unrelated AfDs, is that when a merge proposal to a non-nominated article is made at an AfD, then the merge proposal '''must''' be announced at the talk page of the merge target. To do otherwise is to risk a conflict between the local consensus of AfD participants to add material to an article and the local consensus of editors of that article not to add that material. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein|talk]]) 17:38, 4 November 2021 (UTC) |

== Inline <nowiki>{{harvtxt}}</nowiki> Must Be Enclosed in <nowiki><ref></nowiki> Tags == |
|||
And if it's a list of <math>x-1/x=c</math> problems, why doesn't it give the answer (''x'')? |
|||
Per the following excerpt from [[Template:Harvard citation]], I am correct in stating that all instances of <nowiki>{{harvtxt}}</nowiki> '''''MUST''''' be enclosed in <nowiki><ref></nowiki> tags, regardless of whether it is part of the article or not: |
|||
Have any of these questions been raised by the proponents of other theories, such as the trigonometry theory? |
|||
<code>Also note that inline use of these templates, i.e. use of <nowiki>{{harv}}</nowiki> without <nowiki><ref>... </ref></nowiki> tags around it, was deprecated in September 2020.</code> |

I understand that editing guidelines may have changed since you last checked the style recommendations on this topic, [[User:David_Eppstein]], but that is no excuse to be rude. This has been depreciated for over three years at this point, so please be respectful, especially when you are provably wrong.

:You are absolutely right that Columns 2 and 3 of the tablet do not contain <math>(x-1/x)/2</math> and <math>(x+1/x)/2</math>. A careful reading of Robson shows that she is not actually claiming that they do. According to the reciprocal-pair proposal there is an additional process that is carried out to produce the numbers in Columns 2 and 3 involving the successive removal of common regular factors. At the time you made your comment, the Wikipedia article did not mention this extra step, but it has now been added. The formulas the article gives for the numbers in Columns 2 and 3 now include an additional factor, ''a'', that accounts for the effect of this additional process. |

::First of all, I feel like we got off on a bad footing. I am ''not'' trying to edit war with you, nor do I think our ideas for the article are incompatible. I apologize if I came off as rude, as that was not my intention. Additionally, I want to emphasize that I am ''not'' editing in bad faith, nor did I mean to come off as condescending. In fact, I initially assumed your reversions were also in bad faith, but that assumption was wrong. For that assumption, I apologize. This debacle ultimately stems from a miscommunication in terms of what our visions are for the article, which is why I created this talk post. My goal here is to ''collaborate'' with you, and to understand ''why'' you're saying what you're saying, while also explaining my position in the process. I don't want to fight with you at all, we just need to communicate our goals clearly and professionally. I ask that you treat me with the same respect I am treating you, because I really do believe we can work this out, and have a higher-quality article because of it. With that said, I'll do my best to respond to your comment so we can get on the same page. Please let me know your thoughts on this, I genuinely care about what you have to say. |

I don't think we should remove the text from </nowiki>[[Template:harvtxt]] from the article entirely, but it would be beneficial to convert to the more common Wikipedia reference style (and minorly reword where necessary). My preference would be to convert the references to templates like [[Template:Cite_book]] and [[Template:Cite_journal]] inside <nowiki><ref> tags, but </nowiki>[[Template:harv]] is completely acceptable within a <nowiki><ref> tag too.

== Puzzling attribution claim == |
|||
:One other thing is that Robson is not, as often stated, claiming that the purpose of the tablet was to provide teacher's notes for solving ''x'' − 1/''x'' = ''c'' type problems. Among her actual conclusions are (1) that the tablet most likely is some kind of teacher's notes, (2) that the numbers were produced by a process inspired by the ''x'' − 1/''x'' = ''c'' problem, (3) that the problems being set by the tablet and the problems used to generate the tablet might not be the same, and (4) that the problems being set are uncertain but are likely "some sort of right-triangle problems". (See page 202 of "Neither Sherlock Holmes nor Babylon".) As an aside: from the description in Buck's article, it appears the Voils may actually have made the claim often attributed to Robson. Since Voils' paper was never published, this seems impossible to confirm now. |
|||
I removed the following from the introduction: |
|||
:In answer to your question about why the tablet doesn't give the "answer" ''x'', two comments: (1) if the problems set by the tablet aren't quadratic-equation problems, then ''x'' isn't actually the answer, and (2) Robson, in fact, does believe that the broken-off portion of the tablet did contain ''x'' and 1/''x'' (not because they provide the answers but because of their role in generating the numbers on the tablet). Other scholars who subscribe to the reciprocal-pair theory, however, believe that it probably contained what our article calls ''v''<sub>1</sub> and ''v''<sub>4</sub> rather than ''x'' and 1/''x''. |
|||
*At the same time, one should recall the tablet's author was a scribe, rather than a professional mathematician; it has been suggested that one of his goals may have been to produce examples for school problems. |
|||
Explanation: First off, why do we need this sentence that seems to answer an argument that has not been made in the introduction. Second, detailed objections: (a) It seems to mean "only a scribe". How can we know the writer was only a scribe? Was there anyone who wrote a tablet who was not a scribe? (b) Were there any professional mathematicians? I would be surprised if there were. (c) If the writer was only a scribe, the scribe was using a source for the numbers; presumably the source was knowledgeable about mathematics, so the question of who wrote this tablet is not relevant to understanding its significance. (d) There is some reason to believe the table is trigonometric; the introduction should not be dismissing that idea without even mentioning it. Such a matter should be treated in the body, not the introduction. [[User:Zaslav|Zaslav]] ([[User talk:Zaslav|talk]]) 22:07, 11 May 2024 (UTC) |
|||
:The sentence in question is a, perhaps too concise, paraphrase of the discussion on page 117 of Robson's 2002 article in the ''American Mathematical Monthly,'' which is in the bibliography but, unfortunately, not referenced in this passage. (I think an older version of the Wikipedia article was based almost 100% on Robson's two papers on this topic and was written in such a way that the reader could assume the ideas all came from Robson, so citations were not included everywhere they are needed now that the article contains many other sources.) |
|||
:Finally, observations similar to yours about restricting the numerators and denominators to regular numbers up to 125 have been made in quite a few published papers on the tablet, including those of de Solla Price and Friberg. A small section about this has now been added to the Wikipedia article.[[User:Will Orrick|Will Orrick]] ([[User talk:Will Orrick|talk]]) 15:48, 4 February 2019 (UTC) |
|||
:About your points: (a) Robson makes clear that scribes in ancient Mesopotamia were highly educated members of an elite, not mere copyists. (b) Robson makes exactly this point. (c) See (a). The scribe is generally assumed to be the same person who produced the numbers. (d) Although sets of numbers like those on Plimpton 322 appear elsewhere in ancient Mesopotamian mathematics, there is no evidence of them being used for trigonometry. Indeed there is no evidence of trigonometry at all in the Mesopotamia of this time period. I would call the suggestions of a trigonometric purpose highly speculative and am not aware of any professional historian supporting a trigonometric interpretation. |
|||
:About the removed sentence being an answer to an argument that has not been made, I can see your point. Reading between the lines, it seems to me that Robson wrote this as an attack on a particular group of modern mathematicians who wrote on historical topics and who had a tendency to see the mathematics of ancient cultures as the product of kindred spirits. Robson very much wants to argue that the author of Plimpton 322 was not like a modern mathematician and had some other purpose. My personal opinion is that she takes this line of argument much farther than the evidence supports. |
|||
:Having said all this, I won't miss the sentences you deleted. But in case anyone wants to try to restore a nuanced discussion of these points to the article, I wanted to provide some relevant background. [[User:Will Orrick|Will Orrick]] ([[User talk:Will Orrick|talk]]) 02:03, 12 May 2024 (UTC) |

== Daniel Mansfield == |
|||
For Row15 we get a sample of what the Teacher is teaching. p/q=7/2. And we need to realize that this p/q is in the complementary range, 45deg to 60deg, 2.4142<(p/q)<3.7321, and therefore we want the alternate set (which would be in the 45deg to 30deg range). Using p/q=7/2, our "reduced triple" alternate set becomes: |
|||
a=1 b=((p/q)-(q/p))/2 c=((p/q)+(q/p))/2 with p/q=7/2 |
|||
a=1 b=((7/2)-(2/7))/2 c=((7/2)+(2/7))/2 and solving: |
|||
a=1 b=45/28 c=53/28 and multiplying all sides of this "reduced triple" by 28: |
|||
a=28 b=45 c=53, a primitive PIRT Multiply by 2 and get: |
|||
a=56 b=90 c=106 not a primitive |
|||
So this is the set to use when the PIRT is primitive and a is even, b is odd. And the Teacher would have pointed out that (b) should be a "regular" number, and it is. |
|||

The derivation for Row15 looks wrong because a p of (7) is not regular. But it's right because our test fundamentally is that "the long side must be regular". And the long side is now (p^2-q^2) which is (7^2-2^2)=(49-4)=45 which is indeed regular. |

The use of the short (s), and long (l) designations for the sides of the right triangle put it in superposition. Each one of two solutions for p&q pairs and for reduced triples gives exactly the same result. The orientation of the right triangle remains undefined until (a) and (b) labels are attached. |

|||
:::::Ok, I somehow missed that. I think it worth quoting the passage in full. |
|||
:::::: "We conclude that Plimpton 322 is an investigation into rectangles with regular sides. This does seem related to practical mensuration as briefly suggested by de Solla Price (1964) and more fully by Mansfield & Wildberger (2017), however the precise extent remains unknown. It could have been motivated by a particular practical need, or by a purely theoretical interest in geometry. Although it is more likely that the answer lies somewhere between these two extremes. In any case, Plimpton 322 has nothing to do with the modern study of trigonometry developed by Greek astronomers measuring the sky. Instead, this “proto-trigonometric” study of rectangles seems to have originated from the problems faced by Mesopotamian surveyors measuring the ground." |
|||
:::::Both the ''Guardian'' article and the ''Foundations'' article appeared in August 2021 and the ''Guardian'' article explicitly states that it is reporting on the ''Foundations'' article. The ''Guardian'' article takes the point of view that Mansfield and Wildberger earlier proposed that Plimpton 322 was a trigonometric table constructed with some practical purpose in mind and that the ''Foundations'' article supports that interpretation by discovering the practical application. If Mansfield has walked away from the trigonometric interpretation, it would be good for him to state that clearly. |
|||
:::::It was pointed out by Christine Proust at the time of the 2017 Mansfield and Wildberger paper that Plimpton 3222 can only be seen as trigonometry if you reinterpret "trigonometry" to mean a discipline involving right triangle ratios with no reference to angles, which is not what most people mean by the term. Perhaps the use of "proto-trignometric" is an indirect acknowledgment of that criticism. [[User:Will Orrick|Will Orrick]] ([[User talk:Will Orrick|talk]]) 23:17, 18 September 2024 (UTC) |

The equation is (s/l)^2 + (l/l)^2 = (d/l)^2. (The left-hand column of P322). |
|||
Dividing Row11 thru by 15, and dividing Row15 thru by 2 will get them back to primitive PIRTs. Substitute for (s/l) and solve for (x) in the primitive reduced-triple gets p/q for each of the 15 rows. (The resulting quadratic is solved by completing the square). |
|||
2. X numerators and denominators that are regular numbers up to 125. |
|||
Between 1 and 125 there are only 11 odd and 26 even regular numbers. How about that? |
|||
3. why are the angles of the triangles spaced out by about 1°? |
|||
Would you believe happenstance? With requirements of p and q beween 1 and 125 (nice regular numbers) and long sides a regular number and 15 PIRTS total, what fell out, put in (d/l)^2 decending order, is what we got. (With a few extras). |

==Orphan sentence from edit war?== |
|||
The article finishes its description of the content of P322 with the sentence |
|||
<blockquote>The sixty sexagesimal entries are exact, no truncations or rounding off</blockquote> |
|||
This is a peculiar description, since the numbers are rational. The use the of the words 'sexagesimal' and 'exact' is similar to the phrase 'exact sexagesimal trigonometry', from the title of Mansfield and Wildberger's controversial paper. 'Truncation' and 'rounding' are particular bugbears of Wildberger in his ideas on the non-existence of real numbers. I would suggest removal, not sure if anything is needed in its place; perhaps just a comment that the numbers are rational? <!-- Template:Unsigned IP --><small class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/129.127.37.121|129.127.37.121]] ([[User talk:129.127.37.121#top|talk]]) 01:06, 16 July 2018 (UTC)</small> <!--Autosigned by SineBot--> |

* This statement was here in 2016, before Mansfield and Wildberger's controversial paper. This statement is accurate, and it's not trivial: even rational number could be rounded.

==Article has many issues== |
|||
The article is too technical, too lengthly-wordy-opinionated, relies too much on a handful of sources, and still omits roughly the past two decades of studies. For starters, a specific paper is continuously removed from mention, even though it is frequently discussed and won The Best Writing on Mathematics 2018 by the European Mathematical Society. Someone even moved the more recent talk page entries to the archive, why? [[User:Prokaryotes|prokaryotes]] ([[User talk:Prokaryotes|talk]]) 10:20, 22 April 2019 (UTC) |

:I'm responsible for many of the recent edits that increased the length and technical level of the article, and I'm aware that those are problems. Rather than give my own opinions about what should be done to address those issues, I'd be happy to hear what other people have to say first. |
|||
:One thing I'd like to mention is that part of the reason for the added length was that I tried to include multiple points of view, so I'm especially curious about where you see the current article as too opinionated. The article now includes sources up to 2011, and makes extensive use of the post-2002 sources, but I'd be very interested to hear about other recent sources. The only two that I know about are Rudolf Hajossy's paper, "Plimpton 322: a universal cuneiform table for Old Babylonian mathematicians, builders, surveyors and teachers" and Mansfield and Wildberger's paper. There is also the preprint by Abdulaziz that the Wikipedia article cites but never actually uses. Apart from the rational trigonometry hypothesis in the Mansfield and Wildberger article, all three of these seem to make rather technical criticisms of previous work relating to interpretation of errors, selection criteria, and the feasibility of exact square-root calculations. I have to admit to not thoroughly understanding those arguments, but I'm not sure how much they change the big picture. If anyone has some insight, that would be very helpful. As for rational trigonometry, I was not involved in those discussions, and don't want to weigh in right now. I was not aware that the Mansfield and Wildberger paper had been frequently discussed, or that it had won an award. I will try to look for some of that discussion, but if you have references handy, that would also be helpful.

::Hi Will, please take a look at Archive 1 then, though generally I don't take issue with length, as long it is properly referenced. Large parts without in-line references is the issue. Ofc there can be parts without reference too when explaining something, following a in-line reference. Instead of omitting every bit of mentioning the 2017 MW publication, we should add it as outlined here https://schaechter.asmblog.org/schaechter/2017/10/plimpton-v-muybridge.html I also suggest to align the tables to the right side, so that text can float along it, makes the visual appearing more compact.

:::Hi Prokaryotes. Now that you point it out, I see that the section "Content" contains no in-line references at all. I'll try to work on fixing that. Are there other sections that need more references? One thing that would slightly shorten the "Content" section would be if we could omit the controversy about the 1s in column 1. All recent papers I know of agree they were there, as is clear from the high-resolution CDLI image in our "External links" section. Britton, Proust, and Shnider say in their article that this should be a non-issue. |

::::: [[User:Prokaryotes|prokaryotes]] please allow me to offer helpful advice. It's very easy to win an issue on Wikipedia if you point to a couple of good sources. However when there is a prior consensus, each attempt to pressure an issue ''while failing to present sources to adequately support your positions'' tends to have the effect of further solidifying opposition. If you have good sources, identifying them specifically is extremely effective. If you don't have the sources to point to, pressing the issue will only work against you. |

::::: I regret wasting my time digging through the Scholar link you provided. I didn't check all results there, but most turned out to be clearly frivolous search results. The only one of clear relevance was the reprint in ''Best Writing on Mathematics 2018''. If anyone wants to reopen discussion on the Mansfield-Wildberger paper I suggest and request that you identify ''specific'' sources showing what impact or reception the concepts have had in the field. I would certainly support inclusion of any content that was demonstrably a "Hot topic" in the field. The ''Best Writing'' reprint is a bit interesting, but I don't think that's going to do it. Vague assertions won't work, and pointing to search results implying "there's gold in there somewhere" doesn't work very well a reasonable inspection turns up piles of slag.

We strive for articles in an impartial tone that document and explain major points of view, giving due weight with respect to their prominence.

In some areas there may be just one well-recognized point of view; in others, we describe multiple points of view, presenting each accurately and in context rather than as "the truth" or "the best view". All articles must strive for verifiable accuracy, citing reliable, authoritative sources, especially when the topic is controversial or is on living persons.

::::I'm not sure what the reaction of a reader seeking information on Mansfield and Wildberger is likely to be when they arrive at our article. I would guess that most such readers will come because they are intrigued by the idea that the Old Babylonians knew trigonometry over a thousand years earlier than the civilizations generally credited with its invention. But a second kind of reader may come because they have heard that the Old Babylonians knew a better, more accurate form of trigonometry than our modern one, a form that may soon revolutionize the practice and teaching of mathematics. |
|||
::::The first type of reader may leave satisfied, since they will read about the old observation that column 1 of the tablet contains the secant squared of a series of right triangles whose small angle decreases from about 45° to about 30° in roughly 1° increments. They will also learn that a leading expert in Mesopotamian mathematics regards this interpretation as "conceptually anachronistic", which I think is worth knowing. So they go away knowing that the trigonometric interpretation is a possibility that some researchers have proposed, but that, based on what we know of the Mesopotamian conceptual appartus, it is unlikely to be correct. Such a reader may be slightly puzzled if they remember that the trigonometric interpretation is supposed to represent a recent "breakthrough" in our understanding of Plimpton 322, whereas the sources cited in our article for the idea are rather old. That puzzlement may itself be a valuable lesson, as it illustrates something about the sensationalistic nature of university press releases and science journalism. More determined readers may be bothered enough by this to seek other sources of information. When they find that the M and W paper was indeed touted as a breakthrough in 2017, they probably are going to wonder what the breakthrough was, and what the difference is between the new hypothesis and the similar earlier ones. I, and I think many other editors of this page, share that puzzlement. I would ask those editors who feel it is important to mention M and W in Wikipedia to suggest how this should be explained to readers. I think, however, that it may be difficult to source such an explanation. When I first heard of M and W's paper, my first question was how their trigonometric hypothesis differed from the old trigonometric hypothesis, and I expected that the approach of most science journalists to the the story would be "discredited trigonometric hypothesis revived in light of new evidence". Not a single article I read actually took that tack; almost all presented the hypothesis as a brand new idea. |
|||
::::I really don't know what we can do for the second kind of reader. The notion that the hypothesized Old Babylonian trigonometry is more accurate than modern trigonometry is, to put it bluntly, promotional bullshit, not backed up by a single authoritative source. I don't think it's worth taking valuable article space to introduce and then shoot down such claims, especially since they are peripheral to an article about ancient Mesopotamian mathematics. Even more worthy of being ignored is the factually incorrect claim that only two fractions can be represented exactly in base 10, whereas many can in base 60. |
|||
::::The situation is truly a mess. I just performed a DuckDuckGo search on "Plimpton 322" and fully a third of the hits on the first couple of pages of search results were to stories about M and W's paper—far more than to any other single paper. Google gives similar results, but I am aware the Google tailors the results it shows to individual users. So by some criterion, the M and W hypotheses is the most widely publicized, the "latest and greatest". However, closer inspection reveals that not a single one of the articles in the search results is written by someone with expertise in ancient Mesopotamian mathematics, and none are suitable as sources for a Wikipedia article. By the way, if we ever do agree that M and W must be mentioned in Wikipedia, I would suggest using Christine Proust's [http://culturemath.ens.fr/content/le-buzz-de-l’été-autour-de-la-tablette-plimpton-322 "Le buzz de l’été autour de la tablette Plimpton 322"] as the source, although the fact that it's in French might be seen as a problem. Proust makes an important point that I haven't seen made explicitly anywhere else, which is that the use of the tablet M and W propose is only "trigonometry" if one redefines that word, and that many readers get the wrong impression because they interpret "trigonometry" with its usual meaning, namely as a system relating length to angle, or equivalently, to arc length. |
|||
::::There actually is a really interesting story to be told about Plimpton 322 that has received almost zero publicity. (It is mentioned in Proust's article, however.) The reciprocal-pair explanation for how the numbers on the tablet were generated came into favor as a result of Robson's 2001 paper, although the idea appeared as far back as the original publication of Neugebauer and Sachs. The arguments of Robson and her predecessors were based on careful piecing together of many strands of indirect evidence. Then, in 2007, Friberg translated two tablets in which the precise kind of calculation proposed in this explanation is carried out in detail and its geometric purpose, namely to produce pairs corresponding to the short side and diagonal of a rectangle, is stated. It's rare enough in science that smoking-gun evidence for a theory shows up like this—much more so, I should think, in a field like history where one can't do controlled experiments and must take what evidence one finds. This truly dramatic discovery is, I think, one of the most exciting things to have happened in the field in a long time. I just wish that it had received even a tenth of the press coverage that M and W's paper got. I would not even have known about it were it not for the paper of Britton, Proust, and Shnider. Despite this confirmation of the reciprocal-pair idea, many mysteries remain, including how the sexagesimal fractions produced by the method get converted to the integers in columns 2 and 3, what the purpose of that was, and why such pairs were being tabulated in the first place. These developments, as of early this year, do appear in Wikipedia's article. Because I only gradually became aware of them as I was in the process of expanding the article, and because I was too timid to refocus the article entirely away from the reciprocal pair versus generating pair debate, the article is now a bit of a mishmash, I'm afraid.

We can all acknowledge that BCE/CE is a derivative of BC/AD, but it's a neutral derivative because it doesn't use non-neutral terms.

*:::Using generic terms for non-generic topics is [[othering]] and is the opposite of neutral.

|||
*:::::What I am saying is that using the name "common era" to name the time period of Christianity (from Christ's birth until now) is an implicit endorsement of the view that Christianity is common and that everything else is uncommon, and is therefore unsuccessful as a way to make the naming scheme secular. As for the rest of your comment, I don't see how using the term "BC" denotes faith in anything, as it is merely saying "before this particular person existed". If you are referring to the technical issue of whether Jesus=Christ and saying that using the word Christ implies belief in that identity, then I suppose you might have some point, but I think that the distinction between Jesus and Christ is irrelevant to most people. For Christians they are two ways of referring to a single person / aspect of the trinity, and for everyone else they are two names for that person worshipped by the Christians. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein|talk]]) 20:03, 9 November 2019 (UTC) |

*::::::The "using the word Christ implies belief in that identity" issue is exactly the problem. He—or they, or "that person" as you said—is not the "Christ" or "Lord" to ~70% of the population on Earth. Yet if someone adds "BC" or "AD" to an article completely unrelated to Christianity, then that's what everyone has to use? Seems pretty ridiculous to me.

==Proposed resolution of the Mansfield/Wildberger edit war== |

I'm about to publish a new article on Plimpton 322 and it would be strange if this page contained no mention of the conjectured, some would say speculative, proto-trigonometric interpretation from 2017. --[[User:Daniel.mansfield|Daniel.mansfield]] ([[User talk:Daniel.mansfield|talk]]) 23:48, 8 July 2021 (UTC) |
|||
:It is false that we do not mention this explanation and it is false that this interpretation is original to Wildberger. See the paragraph of the article that begins "Buck (1980) and Robson (2002) both mention the existence of a trigonometric explanation, which Robson attributes to the authors of various general histories and unpublished works, but which may derive from the observation in Neugebauer & Sachs (1945)". —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein|talk]]) 00:04, 9 July 2021 (UTC) |

|||
:::Different in that it uses the "proto" prefix and is credited to Wildberger rather than to any of the many earlier researchers who discussed this issue, or different in some substantive way?

|||
:::: The article must have contained something new beyond the word "proto" otherwise it would never have passed peer review. The trigonometric way of thinking briefly described by Buck/Neugebauer/Price/Robson or anyone else (except Norman Wildberger) was based on an understanding of trigonometry that involved angles. Those brief mentions never developed further because they are technically anachronistic (which is not to say they are without merit, actually I'd say that Buck/Neugebauer/Price were on to something but couldn't develop it further without running into anachronism). I seem to recall that Christine Proust and Alexander Jones both described this approach as "speculative". They did not describe it as similar to previous conjectures. As I said at the start, happy with calling it speculative.--[[User:Daniel.mansfield|Daniel.mansfield]] ([[User talk:Daniel.mansfield|talk]]) 00:54, 9 July 2021 (UTC) |

:::: More on the novelty of the 2017 paper - ''If the new interpretation is right, P322 would not only contain the earliest evidence of trigonometry, but it would also represent an exact form of the mathematical discipline, rather than the approximations that estimated numerical values for sines and cosines provide, notes Mathieu Ossendrijver, a historian of ancient science at Humboldt University in Berlin.'' and ''A thorough search of other Babylonian mathematical tablets may yet prove their hypothesis, Ossendrijver says. “But that is really an open question at the moment.”'' https://www.sciencemag.org/news/2017/08/ancient-babylonian-tablet-may-contain-first-evidence-trigonometry --[[User:Daniel.mansfield|Daniel.mansfield]] ([[User talk:Daniel.mansfield|talk]]) 01:14, 9 July 2021 (UTC) |
|||
:::: Here is the quote from Alexander Jones in the New York Times, along the same lines as Ossendrijver and I think something along these lines should be included. ''“I think the interpretation is possible,” said Alexander R. Jones, director of the Institute for the Study of the Ancient World at New York University, who was not involved with the research, “but we don’t have much in the way of contexts of use from any Babylonian tablets that would confirm such an intention, so it remains rather speculative.”'' [[User:Daniel.mansfield|Daniel.mansfield]] ([[User talk:Daniel.mansfield|talk]]) 05:20, 9 July 2021 (UTC) |

Repeat backdoor merge proposal
[edit]Please see Wikipedia:Articles for deletion/Si.427 where (again) a merge has been proposed, and contribute if you have an opinion. —David Eppstein (talk) 16:45, 4 November 2021 (UTC)
- Front door actually, I linked it back to the discussion here. Merging as an alternative to deletion is a normal option.Selfstudier (talk) 16:58, 4 November 2021 (UTC)
- My position, which I have expressed repeatedly in many unrelated AfDs, is that when a merge proposal to a non-nominated article is made at an AfD, then the merge proposal must be announced at the talk page of the merge target. To do otherwise is to risk a conflict between the local consensus of AfD participants to add material to an article and the local consensus of editors of that article not to add that material. —David Eppstein (talk) 17:38, 4 November 2021 (UTC)
Inline {{harvtxt}} Must Be Enclosed in <ref> Tags
[edit]Per the following excerpt from Template:Harvard citation, I am correct in stating that all instances of {{harvtxt}} MUST be enclosed in <ref> tags, regardless of whether it is part of the article or not:
Also note that inline use of these templates, i.e. use of {{harv}} without <ref>... </ref> tags around it, was deprecated in September 2020.
I understand that editing guidelines may have changed since you last checked the style recommendations on this topic, User:David_Eppstein, but that is no excuse to be rude. This has been depreciated for over three years at this point, so please be respectful, especially when you are provably wrong. Avereo (talk) 00:51, 2 October 2023 (UTC)
- That message and that discussion is for inline use of {{harv}} for parenthetical inline references that are not part of the article text. For instance, a footnote is not a grammatical part of the sentence that it footnotes. Neither is a parenthetical inline reference like the one in this sentence (Avereo 2023). In contrast, a different template, {{harvtxt}}, is used to create inline text that is text and not purely a reference There is NO REQUIREMENT that referring to the work of Avereo in 2013 must avoid the exact phrasing "Avereo (2023)" in favor of other phrasings like "In 2023, Avereo", or "the work of Avereo in 2023" or "a 2023 work of Avereo". Such a requirement could only be imposed through Wikipedia's manual of style, not its citation guidelines, because the citation guidelines do not apply to the formatting of text that is not a citation.
- You are edit-warring to impose a mistaken idea of how article text should be written based on an RFC that was not about article text. Further that RFC did not prescribe the removal of parenthetical references; it only deprecated them, something very different from forbidding them.
- I understand that you feel strongly about this issue, but please stop your bad edits and your bad faith and condescending assumptions about what other editors may understand, especially when you are provably wrong. —David Eppstein (talk) 01:07, 2 October 2023 (UTC)
- First of all, I feel like we got off on a bad footing. I am not trying to edit war with you, nor do I think our ideas for the article are incompatible. I apologize if I came off as rude, as that was not my intention. Additionally, I want to emphasize that I am not editing in bad faith, nor did I mean to come off as condescending. In fact, I initially assumed your reversions were also in bad faith, but that assumption was wrong. For that assumption, I apologize. This debacle ultimately stems from a miscommunication in terms of what our visions are for the article, which is why I created this talk post. My goal here is to collaborate with you, and to understand why you're saying what you're saying, while also explaining my position in the process. I don't want to fight with you at all, we just need to communicate our goals clearly and professionally. I ask that you treat me with the same respect I am treating you, because I really do believe we can work this out, and have a higher-quality article because of it. With that said, I'll do my best to respond to your comment so we can get on the same page. Please let me know your thoughts on this, I genuinely care about what you have to say.
That message and that discussion is for inline use of {{harv}} for parenthetical inline references that are not part of the article text. For instance, a footnote is not a grammatical part of the sentence that it footnotes. Neither is a parenthetical inline reference like the one in this sentence (Avereo 2023).
- As far as I have been able to find, the most current recommendation is for all uses of both Template:harv and Template:harvtxt to be placed within a <ref> tag, not just in the case of parenthetical inline references. It's very possible I may have missed something, so if you have evidence to the contrary, I would love to see it, but pretty much everything I have found indicates otherwise.
In contrast, a different template, {{harvtxt}}, is used to create inline text that is text and not purely a reference There is NO REQUIREMENT that referring to the work of Avereo in 2013 must avoid the exact phrasing "Avereo (2023)" in favor of other phrasings like "In 2023, Avereo", or "the work of Avereo in 2023" or "a 2023 work of Avereo". Such a requirement could only be imposed through Wikipedia's manual of style, not its citation guidelines, because the citation guidelines do not apply to the formatting of text that is not a citation.
- I understand this, which is why I purposefully didn't just slap a <ref> tag on all instances of Template:harvtxt and call it a day. Like you said, that would break the article's flow, which I do not want to do. While there is nothing inherently wrong with the article's wording, the current approach to referencing isn't as clean as the standard CS1+<ref> reference style. I don't think we should remove the text from Template:harvtxt from the article entirely, but it would be beneficial to convert to the more common Wikipedia reference style (and minorly reword where necessary). My preference would be to convert the references to templates like Template:Cite_book and Template:Cite_journal inside <ref> tags, but Template:harv is completely acceptable within a <ref> tag too. Is your concern with the necessity for rewording that a conversion to CS1+<ref> would require, or is there something else causing you to prefer Template:harvtxt without <ref> tags?
You are edit-warring to impose a mistaken idea of how article text should be written based on an RFC that was not about article text. Further that RFC did not prescribe the removal of parenthetical references; it only deprecated them, something very different from forbidding them
- While it is not forbidden, I believe it would still be in the best interest of the average reader to convert away from the depreciated reference style to a more current one. My preference would be CS1+<ref>, but I'm open to other suggestions if you have any. Is there a reason you have for wanting to stay on the outdated/depreciated reference style? Avereo (talk) 03:32, 2 October 2023 (UTC)
- I am not involved regarding this article but am watching from an earlier fuss. Please correct me if I'm wrong but I think the above boils down to an opinion in which case there is no justification for tagging the article, particularly when reverted. Editors are free to contribute to the article but should not pass by to impose their preferences. Either remove your tag or point to a discussion showing that articles like this must be tagged. Did the people in that discussion know what deprecated means? Johnuniq (talk) 04:03, 2 October 2023 (UTC)
- OMG I just examined the wording in the tag. It's deprecated not depreciated. Johnuniq (talk) 04:04, 2 October 2023 (UTC)

Puzzling attribution claim
[edit]I removed the following from the introduction:
- At the same time, one should recall the tablet's author was a scribe, rather than a professional mathematician; it has been suggested that one of his goals may have been to produce examples for school problems.
Explanation: First off, why do we need this sentence that seems to answer an argument that has not been made in the introduction. Second, detailed objections: (a) It seems to mean "only a scribe". How can we know the writer was only a scribe? Was there anyone who wrote a tablet who was not a scribe? (b) Were there any professional mathematicians? I would be surprised if there were. (c) If the writer was only a scribe, the scribe was using a source for the numbers; presumably the source was knowledgeable about mathematics, so the question of who wrote this tablet is not relevant to understanding its significance. (d) There is some reason to believe the table is trigonometric; the introduction should not be dismissing that idea without even mentioning it. Such a matter should be treated in the body, not the introduction. Zaslav (talk) 22:07, 11 May 2024 (UTC)
- The sentence in question is a, perhaps too concise, paraphrase of the discussion on page 117 of Robson's 2002 article in the American Mathematical Monthly, which is in the bibliography but, unfortunately, not referenced in this passage. (I think an older version of the Wikipedia article was based almost 100% on Robson's two papers on this topic and was written in such a way that the reader could assume the ideas all came from Robson, so citations were not included everywhere they are needed now that the article contains many other sources.)
- About your points: (a) Robson makes clear that scribes in ancient Mesopotamia were highly educated members of an elite, not mere copyists. (b) Robson makes exactly this point. (c) See (a). The scribe is generally assumed to be the same person who produced the numbers. (d) Although sets of numbers like those on Plimpton 322 appear elsewhere in ancient Mesopotamian mathematics, there is no evidence of them being used for trigonometry. Indeed there is no evidence of trigonometry at all in the Mesopotamia of this time period. I would call the suggestions of a trigonometric purpose highly speculative and am not aware of any professional historian supporting a trigonometric interpretation.
- About the removed sentence being an answer to an argument that has not been made, I can see your point. Reading between the lines, it seems to me that Robson wrote this as an attack on a particular group of modern mathematicians who wrote on historical topics and who had a tendency to see the mathematics of ancient cultures as the product of kindred spirits. Robson very much wants to argue that the author of Plimpton 322 was not like a modern mathematician and had some other purpose. My personal opinion is that she takes this line of argument much farther than the evidence supports.
- Having said all this, I won't miss the sentences you deleted. But in case anyone wants to try to restore a nuanced discussion of these points to the article, I wanted to provide some relevant background. Will Orrick (talk) 02:03, 12 May 2024 (UTC)
Daniel Mansfield
[edit]Can we acknowledge Daniel Mansfield's work on this [1]? Onanoff (talk) 15:03, 11 July 2024 (UTC)
- I assume you've read the prior discussion of this, some on this very page? To reopen this question, I think there would need to be some new development that hasn't already been discussed. Will Orrick (talk) 17:26, 11 July 2024 (UTC)
- In case you didn't see the archived discussion, there is lots of it:
- https://en.wikipedia.org/wiki/Talk:Plimpton_322/Archive_1 Barryriedsmith (talk) 16:17, 12 July 2024 (UTC)
- It might amuse some people here that Mansfield has a later paper on Plimpton
- Mansfield, Daniel F. (1 December 2021). "Plimpton 322: A Study of Rectangles". Foundations of Science. 26 (4): 977–1005. doi:10.1007/s10699-021-09806-0. ISSN 1572-8471.
- From that his new theory seems to be the tablet is an investigation into rectangles with regular sides, and "has nothing to do with the modern study of trigonometry" rational or otherwise.--Salix alba (talk): 20:57, 18 September 2024 (UTC)
- The Guardian article linked to by Onanoff and the Foundations of Science article are about the same piece of work. And the Foundations article has plenty of discussion of trigonometry and "proto-trigonometr[y]". I don't know where the quoted phrase, "has nothing to do...", comes from. It doesn't seem to be from Mansfield. It also doesn't appear that he's moved too far from the position taken in the paper with Wildberger. Will Orrick (talk) 21:56, 18 September 2024 (UTC)
- The quote is from Mansfield conclusion in the Plimpton 322: A Study of Rectangles paper. --Salix alba (talk): 22:04, 18 September 2024 (UTC)
- Ok, I somehow missed that. I think it worth quoting the passage in full.
- "We conclude that Plimpton 322 is an investigation into rectangles with regular sides. This does seem related to practical mensuration as briefly suggested by de Solla Price (1964) and more fully by Mansfield & Wildberger (2017), however the precise extent remains unknown. It could have been motivated by a particular practical need, or by a purely theoretical interest in geometry. Although it is more likely that the answer lies somewhere between these two extremes. In any case, Plimpton 322 has nothing to do with the modern study of trigonometry developed by Greek astronomers measuring the sky. Instead, this “proto-trigonometric” study of rectangles seems to have originated from the problems faced by Mesopotamian surveyors measuring the ground."
- Both the Guardian article and the Foundations article appeared in August 2021 and the Guardian article explicitly states that it is reporting on the Foundations article. The Guardian article takes the point of view that Mansfield and Wildberger earlier proposed that Plimpton 322 was a trigonometric table constructed with some practical purpose in mind and that the Foundations article supports that interpretation by discovering the practical application. If Mansfield has walked away from the trigonometric interpretation, it would be good for him to state that clearly.
- It was pointed out by Christine Proust at the time of the 2017 Mansfield and Wildberger paper that Plimpton 3222 can only be seen as trigonometry if you reinterpret "trigonometry" to mean a discipline involving right triangle ratios with no reference to angles, which is not what most people mean by the term. Perhaps the use of "proto-trignometric" is an indirect acknowledgment of that criticism. Will Orrick (talk) 23:17, 18 September 2024 (UTC)

This article is wretchedly bad
[edit]It is impenetrable to a generalist newcomer. It does not say anything about the general significance and meaning of Plimpton 322. Cooke (talk) 14:44, 13 December 2024 (UTC)
- Do you have a concrete suggestion for improvement? Which part do you find impenetrable? What do you think the "general significance and meaning" is that is not being conveyed? I must say I'm not very impressed with the tone of your complaint. –jacobolus (t) 19:03, 13 December 2024 (UTC)
