== [[Beal's conjecture]] ==

The article [[Beal's conjecture]] has been the recent target of a crank who refuses to get the point.  It probably needs to be watched by more people and/or temporarily semi-protected.

== Template:Hardy and Wright ==

Some time ago I created [[:Template:Hardy and Wright]] to save myself and others time.  It would be nice to be able to add the edition as a parameter, and select the appropriate bibliodata, but unfortunately I'm not fluent in template-speak.  Is anyone willing to expand it?  The data I have for other editions is
* {{citation | last1=Hardy
| first1=G.H.

| last2=Wright

OK I've added an edition parameter so
*{{tlx|Hardy and Wright}} gives 
**{{Hardy and Wright}}
*{{tlx|Hardy and Wright|edition{{=}}5th}} gives 
**{{Hardy and Wright|edition=5th}}
*{{tlx|Hardy and Wright|edition{{=}}4th}} gives 
**{{Hardy and Wright|edition=4th}}
Hope that OK.--[[User:Salix alba|Salix alba]] ([[User talk:Salix alba|talk]]): 18:25, 1 June 2014 (UTC)

== Deletion discussion on Polynomial transformations ==

The article [[Polynomial transformations]] is being discussed for possible deletion at [[Wikipedia:Articles for deletion/Polynomial transformations]]. --[[User:Bejnar|Bejnar]] ([[User talk:Bejnar|talk]]) 00:56, 5 June 2014 (UTC)

== Alphabetical order for glossaries ==

I posted a suggestion at [[Talk:Glossary of category theory]] but realised that it would apply more generally.  Many but by no means all of the glossary articles in [[:Category:Glossaries of mathematics]] list entries in alphabetical order.  It seems to me that for those ordered by subtopic, the reader who doesn't know exactly what a concept is has to scan the article: the editor who can't fit an entry into an existing subtopic has difficulty placing it.  Would uniformly alphabetical order be preferable?  [[User:Deltahedron|Deltahedron]] ([[User talk:Deltahedron|talk]]) 19:13, 5 June 2014 (UTC)

: Alphabetization makes sense to me. For a glossary type of article, it is best to follow the manual of style [[MOS:GLOSSARIES]]. In the section [[MOS:GLOSSARIES#General guidelines for making glossaries]], alphabetization is specified. If folks want to create a hierarchical organization of terms, an outline article according to [[WP:OUTLINE]] would be a better approach. --[[User:Mark viking|Mark viking]] ([[User talk:Mark viking|talk]]) 21:22, 5 June 2014 (UTC)

== [[Quotient space]] ==

Input from mathematics editors may be helpful. See [[Wikipedia:Redirects for discussion/Log/2014 May 29#Quotient Space]]. This is a deletion debate for the redirect, but it might also be kept as a redirect to [[Equivalence class]], [[Quotient space (topology)]] or something else. The term [[Quotient space]] gets more than 100 incoming links from math articles, so it may be important to handle it correctly.

== LaTeX error messages ==

Is anyone getting odd LaTeX error messages of the form ''Failed to parse (PNG conversion failed; check for correct installation of latex and dvipng (or dvips + gs + convert))''?  I'm seeing them on [[Bott–Samelson resolution]], for example, where <nowiki>X_{\overline{w}}</nowiki> seems to work <math>X_{\overline{w}}</math>  but
:<nowiki>:Z_\overline{w} \to X_\overline{w}</nowiki>
does not
:<math>Z_\overline{w} \to X_\overline{w}</math>
[[User:Deltahedron|Deltahedron]] ([[User talk:Deltahedron|talk]]) 08:43, 8 June 2014 (UTC)
:That wouldn't work in ordinary latex either, would it?  The error message could be more informative though. [[User:Sławomir Biały|<span style="text-shadow:grey 0.3em 0.3em 0.1em; class=texhtml">Sławomir Biały</span>]] ([[User talk:Sławomir Biały|talk]]) 11:46, 8 June 2014 (UTC)
::Ah, I see now.  I thought it was a problem with the implementation, rather than an actual error!  It should have been <nowiki>:Z_{\overline{w}} \to X_{\overline{w}}</nowiki> giving <math>Z_{\overline{w}} \to X_{\overline{w}}</math> of course.

== Relationship with [[Encyclopedia of Mathematics]] ==

The ''[[Encyclopedia of Mathematics]]'' is now a wiki supported by [[Springer-Verlag]].  The text from Springer remains copyrighted to Springer but any new articles added and any changes made to existing articles will come under the Creative Commons Attribution Share-Alike Licence.  The articles need work because the formulae in the Springer version now exist only as PNG and the TeX source needs to be recreated.  However, every article renewed in this way comes under the new licence, and so is presumably compatible with Wikipedia.

Is there any appetite for an effort to recreate these articles and bring them into Wikipedia?  [[User:Deltahedron|Deltahedron]] ([[User talk:Deltahedron|talk]]) 20:49, 15 May 2014 (UTC)

:How many articles are there? (It is a tempting challenge to write a PNG to LaTeX converter&hellip;) [[User:YohanN7|YohanN7]] ([[User talk:YohanN7|talk]]) 21:19, 15 May 2014 (UTC)

::Eight thousand, I'm told.  [[User:Deltahedron|Deltahedron]] ([[User talk:Deltahedron|talk]]) 21:24, 15 May 2014 (UTC)

:Just for a record, I'm planning to import some of articles from eom to here (cf. my TODO.) Right now, I'm preoccupied with other stuff. -- [[User:TakuyaMurata|Taku]] ([[User talk:TakuyaMurata|talk]]) 22:07, 15 May 2014 (UTC)

::Hi. I was contacted as a volunteer (since I do a lot of work with copyright) and asked to review this. I just wanted to make sure that their license statement isn't misinterpreted. :) New changes come under Creative Commons Attribution Share-Alike but do not change the copyright of the underlying material. So, articles renewed are not autoamtically relicensed - only the new content is. See, for example, http://www.law.cornell.edu/uscode/text/17/103:
:::::The copyright in a compilation or derivative work extends only to the material contributed by the author of such work, as distinguished from the preexisting material employed in the work, and does not imply any exclusive right in the preexisting material. The copyright in such work is independent of, and does not affect or enlarge the scope, duration, ownership, or subsistence of, any copyright protection in the preexisting material.}}
::So the original copyright is untouched and the content from the original would not be compatibly licensed, but new material added would be. See also [[Derivative work]]. This is consistent with the source's statement that "The original articles from the Encyclopaedia of Mathematics remain copyrighted to Springer but any new articles added and any changes made to existing articles within encyclopediaofmath.org will come under the Creative Commons Attribution Share-Alike License." It doesn't say that the existing articles will come under the Creative Commons license - only that the "changes" will. :) --[[User:Moonriddengirl|Moonriddengirl]] <sup>[[User talk:Moonriddengirl|(talk)]]</sup> 13:00, 20 May 2014 (UTC)
:::Strictly speaking it's the licence, not the copyright we need to know about.  I agree it's not clear whether modified articles will come entirely under the new licence: perhaps someone will clarify that.  [[User:Deltahedron|Deltahedron]] ([[User talk:Deltahedron|talk]]) 19:19, 30 May 2014 (UTC)

If I remember correctly, any change to an existing article renders the article to be under cc-by-sa. The logic is like this: licensing doesn't work word-by-word. Say, you added a single word to the original eom article; it's not like that that single word is licensed under cc-by-sa and the rest is not under cc-by-sa. In a case of math, sometimes, contributing a single word can be a substantial contribution (e.g., you added "complete" to metric space.) In other words, by editing an article, you created a "new" article and any new article will come under cc-by-sa. If you like an analogy, it's like editing a picture. You don't license the picture by pixel-by-pixel; that's just absurd. -- [[User:TakuyaMurata|Taku]] ([[User talk:TakuyaMurata|talk]]) 23:09, 6 June 2014 (UTC)

: Is this understanding of the license somehow supportable?  It seems rather overly permissive.  My understanding would err on the side of caution: as a rule ''new articles'' will be covered under the new license, but old articles are not.  There might be some exemptions to the latter.  For instance, a wholly new paragraph in an older article might be cc-by-sa.  But I think it is almost certainly not true that changing a single word makes the entire article fall under a compatible license.

== List of Italian Mathematicians Question, :Those already on Italian Wikipedia listed here. ==

I was looking at [[List of Italian mathematicians]] to see which ones were red linked and needed articles.  I tried Ugo Barbuti by chance, and noticed that, even though he is red in English, he is already listed in the Italian Wikipedia.  I decided to check the list to see which ones were available in English and which in Italian.  I did the list in two parts, one for the red links and one for the blue, just in case.  All of the red links seem to be available in the Italian Wikipedia.  Could these all be automatically redirected?

I don't know about other people, but even though my parent language is English, I use Chrome for my browser and right click to translate when I run into any other language.  It gives OK English, mostly readable.  As a service to visitor could we give them the Italian link for now?

Is there a translation project for these pages?  Could a simple page be created for each in English that points to the Italian page and mark it as a stub?  What about automatic translation, as poor as it might be, and put a banner at the top to say it was auto translated and needs a human editor?  That way if someone finds it through Google or other search, they might be prompted to edit someone they know, or were looking for.

=== Vandalism ===

I found that Fibonacci was not on this list!  I added him. [[User:Michael Hardy|Michael Hardy]] ([[User talk:Michael Hardy|talk]]) 19:23, 13 June 2014 (UTC)

:: Now I've undone [https://en.wikipedia.org/w/index.php?title=List_of_Italian_mathematicians&diff=577731415&oldid=577464957 this vandalism] from October 2013, which left us with the bizarre spectacle of a "[[list of Italian mathematicians]]" that didn't mention the one Italian mathematician that every literate person knows of. [[User:Michael Hardy|Michael Hardy]] ([[User talk:Michael Hardy|talk]]) 19:55, 13 June 2014 (UTC)

== A good list of links that needs to be in a more prominent place ==

As you know, Wikipedia is notorious for long lists of little importance.  My problem is just the opposite.  This excellent (and mercifully short) list,

*'''[[Linear_equation#Algebraic_equations]]'''

is buried on a not-so relevant page.  I think it belongs on [[Algebraic equation]] or perhaps [[Algebraic expression]].  Perhaps someone should write a template or something?--[[User:Guy vandegrift|guyvan52]] ([[User talk:Guy vandegrift|talk]]) 14:58, 8 June 2014 (UTC)

:I moved the list to [[Algebraic equation]], keeping a few [[linear equation]] links, and adding a link to Algebraic equation.  I think it looks better now.  I also reordered the links in order of usage, to my best guess.  Hope that works for you.  I will let you tackle the templates.  But I think it is fixed for now.[[User:RC711|RC711]] ([[User talk:RC711|talk]]) 16:45, 14 June 2014 (UTC)

== Random Math Article link Broken ==

In this article there is a link for a random math article.  It points to http://tools.wmflabs.org/jitse-bot/rpim but seems to be broken.  I would like to look at random articles in a general category like mathematics.  I presume it is looking at the list of articles and selecting from that.  Can that be done for any subject?

[[User:RC711|RC711]] ([[User talk:RC711|talk]]) 03:39, 13 June 2014 (UTC)

:See [https://en.wikipedia.org/wiki/Special:RandomInCategory Random page in category - Wikipedia, the free encyclopedia].
:—[[User:Wavelength|Wavelength]] ([[User talk:Wavelength|talk]]) 19:25, 13 June 2014 (UTC)

::Apparently this special page selects a random article in the specified category, '''not''' in the subcategories. Called on "mathematics" the random choice is done among 18 categories and 13 articles, that is 31 items. Absolutely not useful! [[User:D.Lazard|D.Lazard]] ([[User talk:D.Lazard|talk]]) 20:28, 13 June 2014 (UTC)

:::Oh. Thanks for the details.  I was being hopeful that it would pick among the some 30,000 math articles in the list of math articles, or among the categories and drill down.  I would like a search on Wikipedia to find pages in any broad topic.  Like a random page about chemistry, or one about birds, or one about snakes, or one about European cities - something like that.  If we can define lists of pages with common themes, then it is simply a matter of picking a random number and then looking for that index to the particular list.  Mathematics is the only subject I found with a master list of pages like this.  I have been trying to drill down in category trees from a top page like Category:Mathematics or Category:Science to find all the child pages, working through all the subcategories. Work in progress.[[User:RC711|RC711]] ([[User talk:RC711|talk]]) 20:50, 13 June 2014 (UTC)

:At any rate, it would be nice to get Random mathematics article back up.  Perhaps someone should ping Jitse?  [[User:Sławomir Biały|<span style="text-shadow:grey 0.3em 0.3em 0.1em; class=texhtml">Sławomir Biały</span>]] ([[User talk:Sławomir Biały|talk]]) 21:44, 13 June 2014 (UTC)

== A challenge from Jimbo Wales ==

[[User:Jimbo Wales]] posted the following in response to a question about WMF plans for mathematics software development:
::It might be helpful to give more specific details. "png is still standard" is a tantalizing clue but... what do you recommend instead? What does the dream solution look like? What is currently state of the art '''on the web''' in terms of math editing and rendering software? The last time I looked into this (admittedly quite some time ago) what most math editors wanted was LaTex support, and rendering to png was a reasonable way to render. So, that's what we have now. What would math editors prefer today? I'm happy to help but it would be delicious if I had an NPOV summary of the current state of the art, how it compares with what we support, and some basic first step explanations of what the steps are to get from where we are to where we want to be, what help we might be able to engage from the broader math community, and what engineering costs we might expect to shoulder on our end. We have a new CEO now, specifically chosen for tech/product focus, and so a lot of things will be up for discussion over the next year or two.--[[User:Jimbo Wales|Jimbo Wales]] ([[User talk:Jimbo Wales#top|talk]]) 20:08, 6 May 2014 (UTC)

I wouldn't rule out WYSIWYG editors. There's one I have that works pretty well for simple equations, the one built into Apple's Grapher (in the Utilities folder on any modern Mac). You can do a suprising amount with it. It's keyboard driven rather than mouse, so you're typing and using shortcuts to place things rather than manually placing them but that works well as it means the app does all the layout, LaTeX like. There's also a toolbar for inserting things you don't know how to type, much like our edittools.

I would question the assertion that most new math editors know LaTeX. I didn't pick it up while doing maths at school or as an undergraduate, only later, and I imagine this is fairly common at undergraduate level, where at least in maths your main tasks are to learn things to pass exams. An equation editor though would help non-mathematicans more; right now you need LaTeX for things like matrices, all but the simplest of formulae, even when they appear in non-maths articles.--<small>[[User:JohnBlackburne|JohnBlackburne]]</small><sup>[[User_talk:JohnBlackburne|words]]</sup><sub style="margin-left:-2.0ex;">[[Special:Contributions/JohnBlackburne|deeds]]</sub> 02:33, 7 May 2014 (UTC)
: Hello, Jimbo --- interesting to see you posting here. To see examples of how MathJax works, look at math.stackexchange.com&nbsp;.  It works really well.  It matches the size of the surrounding text and it doesn't get misaligned the way inline math notation on Wikipedia often does.  (However, on that site, one sees some amazingly unskilled uses of it.  I marvel at the fact that it is humanly possible to acquire such extraordinary unskillfulness.) [[User:Michael Hardy|Michael Hardy]] ([[User talk:Michael Hardy|talk]]) 03:20, 7 May 2014 (UTC)

:I agree with you that most new math editors probably do not know any TeX.  Despite that, I think it is reasonable to ask them to learn a little.  Learning basic TeX is like learning basic wiki markup.  It's nice to have an editor where you can push a button to turn on italics, but learning to insert two single quotes is not difficult.  Similarly, learning to enter <tt>\frac{1}{2}</tt> to generate the fraction <math>\frac{1}{2}</math> is not hard.  Nor is learning to enter <tt>\times</tt> if you want a times symbol <math>\times</math>.  And that's as much as many people will need and as far as many of them will get with TeX.  In a perfect world, it would be nice if there were a WYSIWIG editor because it would lower the bar to editing.  But the bar is already pretty low, the effort involved in creating a WYSIWIG equation editor is pretty high, and ultimately the mathematics is likely to be translated into TeX for rendering anyway.  [[User:Ozob|Ozob]] ([[User talk:Ozob|talk]]) 03:44, 7 May 2014 (UTC)
::The counter-argument to that is the visual editor exists, at least in part, so editors ''don't'' have to learn wikimarkup. Even without the visual editor you can get a lot done with no experience using the toolbar above the edit window, to insert bold, italic and other formatting so you don't need to learn their markup, and making it easy to learn as you go along because it shows you how to do it.

:: But hitting the '√n' button just gives you <nowiki><math>Insert formula here</math></nowiki>, with no guidance, no example(s) to learn from, not even a link to a help page. There's a limit to what could be done as 'Insert formula here' could be replaced with a wide variety of things, while bold, italic etc. only work one way. But this is also a motivation for doing more as even if an editor learns some equation editing, such as how to make a fraction, it doesn't mean they know other LaTeX such as how to make an integral.--<small>[[User:JohnBlackburne|JohnBlackburne]]</small><sup>[[User_talk:JohnBlackburne|words]]</sup><sub style="margin-left:-2.0ex;">[[Special:Contributions/JohnBlackburne|deeds]]</sub> 10:36, 7 May 2014 (UTC)

:::I think we have two essentially unrelated problems, and that these should be handled independently: rendering from the markup (presently TeX), and capture. Rendering currently is a major headache/obstacle (very slow MathJax, sizing and alignment of PNG, with some font complaints), and this I find really puzzling. Capture relates to interaction with the editor, and I think that here we should stick to an editor-visible and -modifiable markup. A WYSIWYG editor and/or toolbar can be treated as separate exercise.  If we separate these two points (which only involves a decision on what markup to use), and even if we deal with only the rendering problem initially, we will have a major improvement. Treating them as intertwined may contribute to continued stagnation. —[[User_talk:Quondum|''Quondum'']] 11:10, 7 May 2014 (UTC)
::::A problem, which is related to both rendering and editing: In most article the mathematical variables looks differently when displayed (serif italic) and inline (sanserif italic). The use of {{tl|math}} allows inline serif, but few editors know it, and those who know it are often too lazy to use it (14 characters to insert a single variable, as {{tl|math}} does not imply italic). A simple solution could be to introduce $a$ as a shorthand for {{tlg|math|''a''}}, and similarly for more complicated formulas that may be rendered in html.

::::For myself I see the slowness as something that will be fixed eventually by the speed of processors and in the not too distant future, so if there is a problem it really is what should we do about low specced smartphones used in the middle of beyond by poor people? That problem will be around for a while at least and it is one of the aims of Wikipedia to disseminate knowledge widely. Should we just keep pngs for that for the moment? As to having a visual editor for entering maths I would like to see one implemented and the main thing it should do for starters is not ruin a formula if they display it and a small bit is edited - i.e. that it be robust and not generate a huge pile of rubbish just to get the same display. After that it should be easy to use, and after that it should be possible to put in anything (rather than just cope with letting through anything). There's lots of simple maths around where people can contribute who've never heard of TeX. And I agree it should be easy to mark variables in the text as maths symbols. I would prefer them to be italic serif even in non serif text, but if we can have a user CSS style set which dictates that it would solve such problems for like them to match the surrounding text. It may sound trivial to some but there are people who find the mismatch quite annoying. [[User:Dmcq|Dmcq]] ([[User talk:Dmcq|talk]]) 12:18, 7 May 2014 (UTC)

Adding a shorthand alternative writeup language is a peripheral problem, not part of the fundamental one; it could be added at any time. Writing off MathJax's slowness (and frequent complete failure to render!) as "it's fine - we'll just wait until more processor power is on tap" doesn't fly for a number of reasons. Let's focus on fixing what is really holding us back. —[[User_talk:Quondum|''Quondum'']] 13:42, 7 May 2014 (UTC)

:My two cents is that whatever is chosen, please keep it to one choice, and make that choice work, and work well. This includes ease of use, visual appearance and performance. I don't belong to the category of people that believes performance isn't an issue "since future CPU's and internet connections will be faster". If you manage to use up CPU power that is enough to numerically solve Einsteins field equations for 17 colliding black holes when displaying {{math|''f''(''x'') {{=}} ''x''}}, then something is ''fundamentally'' wrong. Such software is simply not sustainable/maintainable in the long run. More importantly, it is very difficult to further develop such software because it is deemed to be a total mess (spaghetti code).

:POV: WYSIWYG editors are nice up to a point. But think about it. What would you ''really'' prefer in the long run, MS Word or a edge-of-the-wedge LaTeX editor?

Besides obvious bug fixes and performance improvement, what I want are (1) the support for commutative diagrams (I've heard the topology coverage here is less satisfactory than, say, algebra one and this might explain this.) (2) the support for simple figure drawing like circles and triangles. In terms of latex, both can be achieved by installing appropriate packages and thus there shouldn't be a technological hurdle. One more thing: the ability to use mathcal fonts that became standard among topologists such as J. Lurie.

* It seems to me obvious, but perhaps worth spelling out, that the only viable form of internal representation of mathematics today is some form of LaTeX markup.

Even the exact choice of underlying markup is not an immediate issue. If there is appetite for more other areas such as graphical editing interface, these can happen later or separately in parallel.

; WMF plans for mathematics 

A couple of weeks ago some comment were made here by editors concerned about the development of mathematics rendering and editing.  The point was made that currently WMF allocates essentially no resources to this and it continues entirely on volunteer effort, which is made less effective by the way it is not integrated into WMF development.  At that time I asked [https://en.wikipedia.org/w/index.php?title=User_talk:Jimbo_Wales&diff=prev&oldid=605002874] what plans WMF had for developing mathematics-based text.  Unfortunately neither you nor anyone else was able to answer before the question was aged off [https://en.wikipedia.org/w/index.php?title=User_talk:Jimbo_Wales&diff=605613372&oldid=605506511].

However, just recently I received an answer to my question from [[User:Jdforrester (WMF)]] who confirmed [https://en.wikipedia.org/w/index.php?title=Wikipedia_talk:WikiProject_Mathematics&diff=606985574&oldid=606974079] in a discussion at [[Wikipedia_talk:WikiProject_Mathematics#VisualEditor_math_formulae]] that the assessment of another editor [https://en.wikipedia.org/w/index.php?title=Wikipedia_talk:WikiProject_Mathematics&diff=606939156&oldid=606865138] that ''WMF has 0 and no plans on Math'' was ''entirely correct''.  

This is very disturbing.  Mathematics support is a key component of writing a serious encyclopaedia and it is quite unacceptable that WMF should devote no resources to its effective development and have no plans to do so. Please would you ask the WMF to reconsider its policy on this matter, and allocate a suitable proportion of its resources to the maintenance, sustainability and development of mathematics rendering and editing?

It would be unfortunate if you went to all that trouble and expense only to have some [[WP:OWN]]ish editor revert it all to the impenetrable versions.

Many of the math articles we have are very useful to people who actually need to know something about the topic. Some years ago Sean Carroll wrote on his blog that he was doing a computation away from his usual workplace and he needed to know the explicit form of some spherical harmonics, and he found them on Wikipedia.

The problem with math really is that the general audience is math illiterate and generally not really interested to learn about the topic. It's therefore pointless to aim too much at the general audience, as we cannot make up for a deficient educational system here. What we can do is present the material in such a way to make it as useful as possible. This means that we relax the Not Textbook rule a bit and write up articles such as [[Methods of contour integration]] or [[Rational reconstruction (mathematics)]] that are very useful to people who are already into these topics who need to learn more.

Basically, the math support here "sucks" in terms of performance and appearance (png is still standard), compared to other notable sites like math.stackexchange. This is more than a practical problem:
# It gives an impression that Wikipedia is less hip (at least used to be). This decreases our ability to attract new editors.
# It gives an impression that WMF doesn't care about the editors, especially those working on serious encyclopedic subjects like math.
:(If I'm allowed to say a bad joke, unfortunately, non-math editors and admins are not smart enough to understand the problems that we math editors are having.)

::It might be helpful to give more specific details.  "png is still standard" is a tantalizing clue but... what do you recommend instead?  What does the dream solution look like?  What is currently state of the art '''on the web''' in terms of math editing and rendering software?  The last time I looked into this (admittedly quite some time ago) what most math editors wanted was LaTex support, and rendering to png was a reasonable way to render.  So, that's what we have now.  What would math editors prefer today?  I'm happy to help but it would be delicious if I had an NPOV summary of the current state of the art, how it compares with what we support, and some basic first step explanations of what the steps are to get from where we are to where we want to be, what help we might be able to engage from the broader math community, and what engineering costs we might expect to shoulder on our end.  We have a new CEO now, specifically chosen for tech/product focus, and so a lot of things will be up for discussion over the next year or two.--[[User:Jimbo Wales|Jimbo Wales]] ([[User talk:Jimbo Wales#top|talk]]) 20:08, 6 May 2014 (UTC)

::::I raised the question here a couple of weeks back [[User talk:Jimbo Wales/Archive 161#The problem with developing maths rendering]] but I think Jimbo was away at the time. 
::::There are a number of problems with the typography of the PNG rendering. A few examples:
{| class="wikitable"

! width="50%" | MathJax
|-
| [[File:Texvc rendering inline.png|335]]
| [[File:MathJax rendering inline.png|314]]
|-
| valign="top" | The most obvious problem with inline formula is the baseline of the formula which is significantly lower than the surronding text. A secondary problem is the font size which is larger the text.
| valign="top" | With MathJax the baseline is better, but still 1px too low. The font size matches correctly.
|-

| [[File:MathJax_rendering_of_Help_Formula.png|MathJax rendering of part of help formula using google chrome on a mac]]
|-
| valign="top" |With display formula texvc performs better. There are problems with [[aliasing]] giving the brackets and all characters a jagged appearance. 
There is the same font size problem.
| valign="top" |There are a few subtile differences: the superscript on the <math>b^2</math> is a little higher in MathJax.
|-
| [[File:Texvc rendering with a zoomed page.png]]

::::::Yes there are some problems with MathJax at the moment. It requires javascript, which not everyone has so some form of fallback is needed. It can be a bit slow to render a page [[Help:Formula]] (a page with very heavy use of mathematics) takes 20s to render because of this {{ping|Eloquence}} Erik Moeller has put a WONTFIX on {{phab|38496}} the main bug to make MathJax the default. There is a plan to do server side cacheing which should speed up the rendering with the Mathoid package and a major update to the [[mw:Extension:Math]] package {{ping|Physikerwelt|Gwicke}} know more about this. The sticking point now seem to be getting this update production ready and getting it though code review. There seems to be very few developers who have the interest/expertise in mathematics rendering to move this forward.
::::::BWT wikipedia uses the [[mw:Extension:Math]] which provides MathJax as a user selectable option and not [[mw:Extension:MathJax]].

:::::::To answer some specific points.  "It requires javascript, which not everyone has so some form of fallback is needed" - I think we can basically ignore this issue right now.  The number of people without access to Javascript is extremely small, and while they do need a fallback, making things worse for 99.9% of all people in order to help the .1% is probably not the best choice.  Let me know if there's something wrong with that thinking.  So what you'd like is some help with resolving the issues of {{phab|38496}} and a commitment from the Foundation (Erik, really) that if we get someone to fix that bug, they're open to implementing it.
:::::::To make my role in this process clear: I totally trust Erik's judgment on the allocation of the limited resources available to him, and it would in any case be foolhardy for me, with no real knowledge of his production timetables, to put pressure on him to elevate this issue just because I've taken an interest in it.  But, two things - I can try to help you campaign to find a community developer interested in this issue.  Not sure how effective that will be but I'm willing to try to shine a light on it.  And as I said above, we have a new executive director now, one brought on board to ramp up investment in product/engineering capacity.  It seems likely that some of the constraints that Erik and the engineering team have faced in the past will be expanded significantly in the next two years, and so now is a good time to make a reasoned case and proposals for improvements that we in the community find important.

===Summary===

::I've incorporated some comments into the text.  If no-one objects I'll take it back to WMF as the Project's view at the weekend.  [[User:Deltahedron|Deltahedron]] ([[User talk:Deltahedron|talk]]) 20:10, 19 June 2014 (UTC)

:::Now posted to [[User_talk:Jimbo_Wales#WMF_plans_for_mathematics_II]].  [[User:Deltahedron|Deltahedron]] ([[User talk:Deltahedron|talk]]) 20:06, 21 June 2014 (UTC)

====Background====
About 1% of Wikipedia's 4.5 million articles are [[Wikipedia#Coverage_of_topics_and_systemic_bias|assessed]] as being in "Mathematics and Logic".  Probably a similar number are in theoretical physics and in computer science.  So in about a hundred thousand articles, the ability to render mathematics is indispensible to the reader: the ability to write and edit mathematics is indispensible to the author and editor.  

Currently the predominant mathematics markup system in all forms of document preparation is some flavour of [[LaTeX]].  It may be presumed that any serious mathematics content contributor will be thoroughly familiar with LaTeX.  LaTeX is rendered on web pages in a variety of ways: currently Wikipedia uses two of the more popular methods, rendering formulae as [[Portable Network Graphics|PNG]] images and rendering dynamically using [[MathJax]].  There are deficiencies in the current implementation of each of these methods. 

The stability and usefulness of ''current'' mathematics rendering is reduced by the following
* Incremental development of reader and editor interfaces is apt to degrade the reader or editor experience without warning.
* Major changes in editor interfaces, such as the introduction of [[Wikipedia:VisualEditor]] and [[Wikipedia:Flow]], may be radically incompatible with existing LaTeX markup practices.
* Effort to support mathematics editing and rendering comes entirely from the volunteer community.  Currently one volunteer is working on mathematics rendering, and support for mathematics editing in VE consisted of one [[Google Summer of Code|GSoC]] summer volunteer.

====WMF planning====
We are reliably informed that WMF has no plans for development of mathematics rendering and editing.  That is, there is no plan to coordinate volunteer effort; no plan to integrate volunteer effort into existing products; no plan to ensure the sustainability of mathematics rendering and editing through major changes to the software and user interface.

As a consequence of the lack of plans, there is no allocation of WMF developer effort to the maintenance, sustainability or enhancement of mathematics rendering and editing.  It is assumed that volunteer developers will undertake any tasks that are necessary, even though there is no plan to coordinate those efforts.

It is reasonable to say that there is considerable expertise and experience in mathematics rendering and editing in the existing editor communities.  There is no explicit mechanism to capture that experience and make use of it in planning, development or review.  Such efforts as have been made to do so are limited in extent and driven by the user community rather than WMF.  The role of Community Advocates in linking the editor community and WMF planning and developers in this context has not been effective.

====Suggestions====
* General
:# WMF planning address the issue of development of mathematics and other complex rendering markup and editing components.  
:# WMF liaise actively and effectively with existing editor and reader communities in (1).
:# WMF draw up roadmap for development of complex rendering and editing.
:# WMF liaise actively and effectively with volunteer developer communities to determine required frameworks and work packages.
:# WMF allocate funds and resources to support work packages.

*Specific
:# Mathematics rendering to be based on MathJax as principal vehicle, with efficiency and resources issues resolved on a wide variety of platforms.
:# LaTeX markup retained as principal mode of editing mathematics text with concomitant option to directly edit at the wikitext markup level.
:# WMF establish a workflow for further development and deployment of the math extension, using the https://www.mediawiki.org/wiki/Extension:Math/Roadmap page to coordinate the development process.
:# WMF designate a fixed contact person at WMF that cares about math related questions and a brief to maintain regular and frequent contact with volunteer community.

*Short-term
:# Fix MathSource mode is currently disabled: see [https://gerrit.wikimedia.org/r/#/c/139439]  which resolves this issue.
:# Fix issues with experimental mathoid (MathML + SVG) support on the Beta Cluster.

Please comment here.  [[User:Deltahedron|Deltahedron]] ([[User talk:Deltahedron|talk]]) 20:13, 6 June 2014 (UTC)

:Excellent summary.  I have one small criticism that point number two under "Specific" is not likely to make much sense to someone reading the summary who is not already familiar with the details of past discussions.  I think this should be stated more plainly. [[User:Sławomir Biały|<span style="text-shadow:grey 0.3em 0.3em 0.1em; class=texhtml">Sławomir Biały</span>]] ([[User talk:Sławomir Biały|talk]]) 10:23, 7 June 2014 (UTC)

;workflow: From my perspective the most important thing is to establish a workflow for further development and deployment of the math extension. There are two volunteers Frédéric Wang and myself actively working on the Math extension. From WMF side the Visual Editor team takes care of the Visual Editor related aspects. For Frédéric and me the main problem is that we have no fixed contact person at WMF that cares about math related questions. I think a very brief weekly Skype meeting with a fixed contact person would eliminate most of the problems. This would eliminate most of the randomness involved in the current development process.
;roadmap: I tried heavily to promote the https://www.mediawiki.org/wiki/Extension:Math/Roadmap page to have a more coordinated development process. Looking at the history indicates that I have changed my username. If anybody here is willing to contribute to the roadmap pleas give me a signal and I'll update the page. Otherwise I see no need to update this page for my own use only.
;source rendering mode: I apologize that the MathSource mode is currently disabled. There is a fix at https://gerrit.wikimedia.org/r/#/c/139439/ which resolves this issue. As soon as this is backported by some WMF employee the source rending mode will be back.
;MathML support: We manged to have experimental mathoid (MathML + SVG) support to the master branch. It works well on private wiki installation, but on the Beta Cluster only the SVG is displayed correctly. The MathML elements like <nowiki><mo><mi>...</nowiki> are removed for some reason. If anyone has an idea why this happens I'd be very happy about comments either here, at my user talk page or at the bug report at https://bugzilla.wikimedia.org/show_bug.cgi?id=66495. (I'll try to visit this page more often)

Hi all,

My name is Adi Khajuria and I am helping out with Wikimania 2014 in London.

One of our initiatives is to create leaflets to increase the discoverability of various wikimedia projects, and showcase the breadth of activity within wikimedia. Any kind of project can have a physical paper leaflet designed - for free - as a tool to help recruit new contributors. These leaflets will be printed at Wikimania 2014, and the designs can be re-used in the future at other events and locations.

This is particularly aimed at highlighting less discoverable but successful projects, e.g:

• Active Wikiprojects: Wikiproject Medicine, WikiProject Video Games, Wikiproject Film

• Tech projects/Tools, which may be looking for either users or developers.

• Less known major projects: Wikinews, Wikidata, Wikivoyage, etc.

• Wiki Loves Parliaments, Wiki Loves Monuments, Wiki Loves ____

• Wikimedia thematic organisations, Wikiwomen’s Collaborative, The Signpost
<br><br>
The deadline for submissions is 1st July 2014
<br><br>
For more information or to sign up for one for your project, go to:

:If the ETC and cut-the-knot have picked it up, it is has seen some review and the ETC is considered reliable, so from that perspective no OR. It seems to be just a very recent result in a niche area of mathematics.

::::Currently such theorems/result could still be incorporated as partial content in survey/summary articles like suggested [[List of triangle centres]] (note however the ETC contains a few thousand, the book version around 400 iirc). I have no objection against a more nuanced version, however there needs to an effective method for blocking unwanted content as their is potential danger that people will try to publish  correct/established directly in WP (instead of elsewhere). Also one needs to keep in mind that there is an infinite number of correct but not-notable mathematical statements/theorems. While there are case where most editors would agree it is ok to have them in WP (despite officially  failing the current notability), there will be probably even more where editors disagree. In particular for the latter group a more nuanced policy should provide an somewhat objective criteria for the decision about the inclusion in WP.--[[User:Kmhkmh|Kmhkmh]] ([[User talk:Kmhkmh|talk]]) 16:31, 22 June 2014 (UTC)

Also, I consider that an article is [[WP:ORPHAN]] in nature if it may be naturally linked to only in lists or in "See also" sections (this is the case for this article, and also for the draft linked to in next section). Therefore, my suggestion is, in the case where notability is dubious, to consider as non-notable a notion or a result that is a quasi-orphan as it cannot be linked to from the text of other WP articles, without ad hoc expansion of these articles.

As far as notability is concerned, the German Wikipedia for instance considers any (math) subject notable, that has been published in established journal or a properly published textbook.
