 * Propose deleting brethren denominations


 * Nominator's rationale: Per Brethren, the Plymouth Brethren are completely unrelated to the Church of the Brethren. I suppose renaming to something like Category:Schwarzenau Brethren denominations might do the trick as well. —Justin ( koavf ) ❤T☮C☺M☯ 23:31, 13 July 2012 (UTC)


 * Comment -- I think this needs to be split so that each of the groups in Brethren has a separate category. These might have the present category, as an ultiamte parent, despite being unrelated.  The problem is more with the North American sub-cat, which is getting in the way of creating a rational tree, based on theological views.  Peterkingiron (talk) 11:05, 14 July 2012 (UTC)
 * Delete there are also Methodist and other groups that use brethren in their name. There is no clear group that can be easily designated as "brethren denominations" and the current name will tend to link unlike things.  There are better names for everything involved, so we should just delete this category.John Pack Lambert (talk) 18:25, 21 July 2012 (UTC)

Category:Films set on the Moon

 * The following is an archived discussion concerning one or more categories. Please do not modify it. Subsequent comments should be made on an appropriate discussion page (such as the category's talk page or in a deletion review). No further edits should be made to this section.


 * The result of the discussion was: Rename. Timrollpickering (talk) 21:43, 5 August 2012 (UTC)
 * Propose renaming Category:Films set on the Moon to Category:The Moon in film
 * Nominator's rationale: Rename. This would bring the categories name in line with others like Category:Mars in film or Category:Saturn in fiction. It also allows for the fact that several films on the list are only partially set on the moon. If you want to leave out the "The" that would be fine. I included it to differentiate from other planets moons and it read oddly to me without it. MarnetteD | Talk 20:30, 13 July 2012 (UTC)


 * Comment "moon" would require "the" before it ("the moon in film") as this indicates a specific moon, (Earth's moon as opposed to one of the moon's of Jupiter). There is only one Mars (that refers to a location astronomical body anyway), so no need to use "the" as in "the mars in film". Brad7777 (talk) 23:25, 13 July 2012 (UTC)
 * Thanks for clearing that up Brad7777. I was trying to be flexible, but, it turns out that was unnecessary. We also want to avoid confusion over "Mooning in film" which would include American Grafitti and numerous other teen comedies heehee Thanks again. MarnetteD | Talk 23:49, 13 July 2012 (UTC)
 * Aww, then we could have a "Mooners" category and everything Brad7777 (talk) 21:44, 14 July 2012 (UTC)
 * I think I'd prefer that the Mars one was renamed Category:Films set on Mars as that seems to follow the naming convention used in Category:Films by geographic setting. This may of course exclude some of its current contents such as Category:War of the Worlds films. Tim! (talk) 07:07, 14 July 2012 (UTC)
 * As I mentioned that has the problem of implying that the entire film is set on Mars. As with those that are in the Moon category some (most) are only partially set there. On the other hand I thought this might come up so if the consensus is to take up Tim!s suggestion I won't object, since my intent was to make the wording the same for both cats, and I hope that the request can be handled from here without having to file a new CFD. MarnetteD | Talk 17:55, 14 July 2012 (UTC)
 * Oppose - there should be two seperate categories here, not one or the other or one renamed to the other. - The Bushranger One ping only 21:47, 15 July 2012 (UTC)
 * I am not asking for a merge. I want there to be two separate categories. I am suggesting that one or the other be renamed so that there is uniformity in there naming for clarity. MarnetteD | Talk 00:56, 20 July 2012 (UTC)
 * I guess that makes sense. Rename then. - The Bushranger One ping only 01:21, 31 July 2012 (UTC)
 * Rename per nom. Category:Films set on the Moon is a set category built around an in-universe characteristic and is, therefore, better suited to a list; Category:The Moon in film would be a topic category for a distinct subject of cultural interest. The proposed title also more closely matches the naming of its parent, Category:Moon in fiction. -- Black Falcon (talk) 05:32, 22 July 2012 (UTC)

 * Propose deleting introductory physics


 * Nominator's rationale: Fails WP:NPOV. Introductory physics is not sourced. WP:NOTGUIDE, Not defining therefore overcategorization Brad7777 (talk) 09:14, 13 July 2012 (UTC)Brad7777 (talk) 13:17, 23 July 2012 (UTC)


 * Oppose. There are numerous "Introduction to ..." articles inhabiting the category to which Wikipedia has given its imprimatur.  Moreover, whether some physics concept is commonly taught in secondary school, even if not sourced, seems like it is easily source-able if challenged.  Sławomir Biały  (talk) 11:19, 13 July 2012 (UTC)
 * Could you link to them, please? Of the 98 pages currently in the category, only three are Introduction to ... articles. -- Black Falcon (talk) 18:25, 5 August 2012 (UTC)
 * Oppose, per Sławomir. The category consists of topics commonly taught in high-school classes and "intro to physics 101" college classes world-wide. While I no longer have an "intro to physics" textbook on my shelves, these abound in any used bookstore in any college neighborhood. So we can readily source the idea that these really are "intro" concepts.   Next: If not here, then where else could we categorize these articles?  Many or most WP articles in math and physics require an advanced degree: even most physics PhD's don't know what a Liouville 1-form is, even though its really just plain-old "classical mechanics"; it would be criminal to put high-school level articles into the same category as the PhD level articles. A category for the elementary topics is quite suitable.  FYI, you may enjoy this: Category:Elementary mathematics which is very rich. linas (talk) 13:54, 13 July 2012 (UTC)
 * Comment I've requested that an article is created at afc, along the lines of "introductory physics". (As well as introductory mechanics and introductory electromagnetism) to match the straight standards of Category:Elementary mathematics. Category:Introductory physics needs a source to prove it is not original, it is neutral and not just a guide. IMHO I believe a list alone could do the job of this category Brad7777 (talk) 15:44, 13 July 2012 (UTC)
 * Why would a list be better than a category?  This is actually something I never really understood about wikipedia-- the many "lists" pages, which not only duplicate material in categories, but badly-- they're typically incomplete, juvenile, and edit-warred by college freshmen facing mid-term exams. So personally, I beleive lists are a bad idea, at a fundamental level; categories solve the job far more elegantly and neatly.linas (talk) 19:00, 14 July 2012 (UTC)
 * Yes, many of the lists could do with a decent amount of work on them. I guess IMHO The main purpose of the categories is to organize the articles in a hierarchical manner. This doesn't help organize any articles, (because in the case of physics, there a few articles which are introductory foo, Introduction to foo or elementary foo, etc.) So organization wise it appears as an original category, that is arbitrarily assigned to physics articles, contributing to overcategorization. An article, list, glossary (etc) on the other hand, which isn't done half-heartedly would be a lot more useful for explaining "introductory physics" in terms of its topics and taking into account educational or pedagogical considerations, and a list (or better) would be more useful for someone who would be studying "introductory physics"; to browse if there are brief descriptions/related equations etc. Brad7777 (talk) 21:17, 14 July 2012 (UTC)
 * I guess I fail to see how its either original, or how its over-categorization. Those criticisms are usually applied to things like Category:Lead singers of do-wop bands who were born in Bristol in 1930 and played football in school which this cat certainly is not. There is no requirement whatsoever that categories be hierarchical: de-facto, they almost never are, and indeed its much better if they are not: if instead they form a directed graph (with cycles, etc.) The goal of a category is not to "explain" it's contents, but to provide a survey of related topics: a kind-of extended "see also" list, a grouping of similar things. linas (talk) 15:08, 17 July 2012 (UTC)
 * I suggest reading WP:CAT and WP:DEFINING. Lack of sources make me think this is not-NPOV or verifiable, but assuming there are sources, how is it defining and therefore not a case of overcategorization? At the moment this appears to fail WP:OC and WP:ORIGINAL SYN (hence IMHO its original). It is also worth noting that in this case the WP:AOAL outweigh the WP:CLS when considering the most likely audience for this notable topic. Brad7777 (talk) 16:16, 17 July 2012 (UTC)
 * I think you are wiki-lawyering. Instead of throwing around these terms, why don't you actually come out and explain what is subjective about it, why it fails to be defining, and in what sense it is over-categorization. You keep making accusations, but you provide no evidence or proof. I think you need to step up to the bar and get serious about this. Perform some research. Go and look at how physics is actually taught in schools.  Get a textbook. Open it. Go through it. Don't spout opinion which has no basis in reality.linas (talk) 01:45, 21 July 2012 (UTC)
 * When I was first introduced to physics in primary school, I remember that we were taught that you can apply forces, and these are either pushing, pulling or twisting forces, however I do not remember part of this introduction mentioning the Parallel axis theorem or most other articles in this category. At the moment the term "introductory physics" is subjective because it is not clear what should and shouldn't be included within it. If there was an article on introductory physics (with acceptable references) mentioning the scope of this term, then this wouldn't matter. But on top of that, almost all the articles in this category, do not state they are apart of "introductory physics", therefore it can not be defining. If the category is not defining, then it is contributing to over-categorization. I hope this is clearer. Brad7777 (talk) 23:58, 21 July 2012 (UTC)
 * I don't see how this is any more is subjective than any other classification topic. For example, the articles on Poisson bracket, symplectic geometry, or Yang-Baxter equation are clearly not "introductory" to anyone but Gromov; no one is going to make that categorization mistake.  Nor is anyone going to accidentally categorize quantum groups as a topic of Category:Atomic physics just because it has the word "quantum" in the title.  Yet, there is always some ambiguity and subjectivity in any classification task: many articles on atomic physics could also be classified under chemistry. Articles such as hyperfine splitting could be classed under nuclear chemistry, atomic physics, or quantum field theory, and its would be quite "subjective" to argue that one of these categories is more appropriate than one of the others.  The question is really this: can anyone with formal training in physics understand when an article belongs in the 'introductory physics' category?  I think the answer is a clear "yes"; its simply not ambiguous.  linas (talk) 03:21, 22 July 2012 (UTC)
 * CommentI have done 2 years of physics at university, therefore I have some formal training. In a way I also think it is simply not ambiguous; after all, I understand what I would class as 'introductory physics', which would be any article aimed towards children in primary school. But I also understand there is possible disagreement between what others would class as 'introductory physics'; therefore it must be ambiguous when the situation hasn't been simplified? This wouldn't even matter if the guidelines were being followed. The term 'Introductory physics' fails WP:DEFINING, so the alternative would be listify, but then the term 'Introductory physics' would have to be verifiable, which would also remove the ambiguity of interpretation of the term. Brad7777 (talk) 09:14, 26 July 2012 (UTC)
 * Delete highly subjective "This category includes topics in physics that are commonly taught in middle school or high school, or may be in the curriculum for college freshmen. See also the list of basic physics topics. The main article for this category is Outline of physics." It seems odd to categorise physical laws by the level of education at which they are taught. I concur with Brad7777's comment that a list would better serve the intended purpose. Tim! (talk) 07:18, 14 July 2012 (UTC)
 * Why do you say "highly subjective"? No professor accidentally walks into a physics 101 class, and accidentally starts lecturing on Morse theory, which is a kind of formulation of classical mechanics, nor do they use Abraham and Marsden for the textbook. (Think back-- what year did you finally stat reading Abraham & Marsden, if ever?)  There's nothing subjective in the idea that one must know certain basic things before moving on to advanced things. Culturally, there is widespread agreement on this topic, and it can be seen simply by looking at the material covered in textbooks. There is nothing at all subjective about it.  linas (talk) 19:00, 14 July 2012 (UTC)
 * Article-ify since it seems inappropriate to have a category on it, since not only does introductory physics cover many of the topics contained within, but advanced physics as well. -- 76.65.131.160 (talk) 09:00, 14 July 2012 (UTC)
 * Comment Category:Introduction to topics in physics might be viable for the "introduction to Y" articles as a category. -- 76.65.131.160 (talk) 09:01, 14 July 2012 (UTC)
 * Delete The inclusion criteria is effectively arbitrary. Also note that there are only 3 "introduction to ..." type articles in the category. IRWolfie- (talk) 10:03, 15 July 2012 (UTC)
 * Why do you say "arbitrary"? This is rebutted above, so why say it again? What, exactly, is "arbitrary" about it? linas (talk) 15:08, 17 July 2012 (UTC)
 * There is only a very rough hazy definition of what constitutes introductory physics. Firstly, what level do we aim it: introductory for those with no scientific background, for those in secondary school or for first year undergraduate physics courses? What constitutes a suitable introductory text book: Undergraduate textbooks, Generic Physics books, Pop science books? IRWolfie- (talk) 03:14, 21 July 2012 (UTC)
 * A pop-sci book would not constitute "introductory physics". I'm not sure what a "generic physics" book is; if a high-school textbook, then yes.  First year undergraduate textbooks are "introductory", second-year are not. linas (talk) 14:47, 22 July 2012 (UTC)
 * Delete we do not break-down subject areas into "intoductory" and "advanced" sections.John Pack Lambert (talk) 19:13, 18 July 2012 (UTC)
 * Huh? What? Sure we do, we do it all the time. Its a major organizing principle behind much of the sciences in wikipedia; its not just this one category. Its ingrained in the nature of scientific understanding.  What part of wikipedia do *you* edit? Do you actually get involved in science articles?linas (talk) 01:45, 21 July 2012 (UTC)
 * Focus on arguments, not editors IRWolfie- (talk) 03:15, 21 July 2012 (UTC)
 * So, for example, we track "introductory" articles in the WP assessment system: here WikiProject Mathematics/Wikipedia_1.0/Basics for example. The corresponding category for this is Category:Elementary mathematics, which has another 12 or so 'elementary' subcategories under it. linas (talk) 14:47, 22 July 2012 (UTC)
 * Keep. Comment: The sourcing criterion in CAT applies to articles, not the categories themselves. It is easy enough to verify that an article belongs in this category - it just has to be covered in an introductory textbook. It is also easy to determine which textbooks are appropriate sources because they always say in the preface what level they are intended for. Perfectly neutral. RockMagnetist (talk) 02:57, 21 July 2012 (UTC)
 * Great, so what level counts as introductory? You can get an introductory textbook on a great many topics within physics. IRWolfie- (talk) 15:59, 21 July 2012 (UTC)
 * The criterion for the category is up to freshman college level (although that could be changed). RockMagnetist (talk) 16:38, 21 July 2012 (UTC)
 * According to some of the keep votes it is up to secondary school (high school). IRWolfie- (talk) 11:42, 22 July 2012 (UTC)
 * Keep It does no harm and it may be helpful to some people. JRSpriggs (talk) 04:35, 21 July 2012 (UTC)
 * Comment As being a concept in "introductory physics" isn't defining for most if not all of these articles, it contributes to over categorization. A list would be just as helpful. Brad7777 (talk) 00:06, 22 July 2012 (UTC)
 * WP:NOHARM - The Bushranger One ping only 05:15, 23 July 2012 (UTC)
 * Keep I agree with JRSpriggs, it does no harm and may be useful. I don't understand the argument that it's somehow anti-NPOV; the stuff covered in a (US) high-school course, plus, roughly speaking, the contents of college courses with names like "intro to physics", and the content of textbooks for such courses, is pretty standard. - Virginia-American (talk) 06:46, 21 July 2012 (UTC)
 * Keep Useful navigation aid. No NPOV problem here because this categorisation is uncontroversial - we are hardly going to see a POV dispute over whether some topic is "introductory" or not. Gandalf61 (talk) 12:31, 21 July 2012 (UTC)
 * Comment if introductory categories are so common where is Category:Introductory chemistry, Category:Introductory biology, Category:Introductory economics, Category:Introductory mathematics, Category:Introductory history, Category:Introductory psychology and Category:Introductory philosophy?John Pack Lambert (talk) 18:29, 21 July 2012 (UTC)
 * Different fields use different names for such concepts. So, for example, there is Category:General economics. By contrast, there is no Category:general physics because actual, working physicists and educators don't ever use that term. There is a Category:Elementary mathematics because, by convention, it is not called Category:Introductory mathematics. Not all fields have a compunction to organize in this fashion. Physics is very heirarchical, you cannot just dive into string theory, without having gone through many years of studying more basic theories.  linas (talk) 15:03, 22 July 2012 (UTC)
 * Delete. Although, as several people have already noted, the nominator's original rationale for deletion is weak, the argument based on overcategorization is much stronger. Overcategorization is potentially harmful, and to avoid it articles should be categorized by their defining characteristics. For most articles in this category, "introductory" is not a defining characteristic. Of course, there are articles like Introduction to angular momentum, but they are already in the hidden category Category:Introduction articles. Others like Fundamentals of Physics are already better categorized by Category:Physics books and Category:Physics education. Overall, Physics education is a good substitute for this category. RockMagnetist (talk) 02:10, 22 July 2012 (UTC)
 * Delete and replace with a Wikipedia Book - This is a good-faith attempt to use a category to create a Wikipedia Book. However, the book tool is a much more suited to this purpose (see, for instance, Book:Physics). The fact that these topics are a part of 'introductory physics' is not at all defining for the topics themselves—i.e., this category constitutes overcategorization—and, therefore, the category ought to be replaced with Book:Introductory physics or Book:Introduction to physics. -- Black Falcon (talk) 04:34, 22 July 2012 (UTC)
 * Keep "Commonly taught" in middle/elementary/high school is precise enough to warrant a category. In my experience, categories on Wikipedia are typically sourced from within the articles they contain, so if all the articles contained in the category contain sourced statements showing that the subject of the article is indeed a common part of pre-college curriculum, then the whole rationale of the proposer simply breaks down.  Piyush (talk) 06:18, 23 July 2012 (UTC)
 * Also, as has already been pointed out Category:Elementary mathematics already exists, is consider a good example of a category. There is no reason why we cannot work on this category and bring it up too the levels of Category:Elementary mathematics.  The only way I see that not happening is if this category is deleted based on some fact-free bombardment with Wikipedia policy articles.  Piyush (talk) 06:27, 23 July 2012 (UTC)
 * Why wouldn't a list suffice, having for example: List of physics concepts on the pre-college curriculum? Aren't all articles, that are related to physic's, introductions? "Elementary mathematics" is a sourced term, but IMHO I guess Category:Elementary mathematics is also contributing to overcategorization. How do these categories help categorize articles?  Brad7777 (talk) 13:17, 23 July 2012 (UTC)
 * I have created List of physics concepts in pre-college curricula. RockMagnetist (talk) 16:27, 26 July 2012 (UTC)
 * They certainly do, and in fact, in Mathematics, Elementary mathematics is a rather well used term: see for example Elementary proof. No matter what the result of this debate, I do hope nobody gets it into their head that even the elementary mathematics category is "overcategorization" and goes ahead trying to delete it.  Piyush (talk) 15:41, 23 July 2012 (UTC)
 * Comment The fact that something is notable only justifies the creation of an article list etc. Articles should be categorized by defining characteristics unless this is impossible. I think these non-defining categories can be avoided with decent articles or lists, and so see no reason to WP:Ignore all rules, after all Wikipedia is not a guide. Brad7777 (talk) 21:04, 23 July 2012 (UTC)
 * I note the lack of consistency amongst keep voters as to the level that introductory covers. IRWolfie- (talk) 09:53, 23 July 2012 (UTC)
 * There is no such lack of consistency, unless someone wants to manufacture one. The only two options I have seen so far are "pre-college" and "first-year college".  At least from what I have seen, most of the difference between the two consists not in the topic themselves, but in the way the topics themselves are presented.   For example, a high school curriculum would probably define moment of inertia in a ad-hoc way (corresponding to the first three sections of the article), while a first-year college may give a glimpse of the tensor formulation (section four in the same article).

 * Keep and oppose deletion. I think this category is both helpful and handy. It is easier to access the simpler concepts in one single category rather than try to wade through a much larger category such as Category:Physics. Steve Quinn (talk) 00:14, 6 August 2012 (UTC)
