Adminship for Farrell99999Edit

I would like to kindly request adminship in this wiki so that I could be able to delete useless pages or vandalised pages and block the troublemakers.

Please log in and move this section to the appropriate place. Thank you.   — Jeff G. ツ 04:51, May 1, 2011 (UTC)

Previous discussion Edit

There's some previous general wiki-related discussion at Talk:Main Page. It will be moved here at some point, to reserve that talk page for Main Page discussion only. - dcljr 00:00, 7 December 2007 (UTC)

The first four sections below were moved from Talk:Main Page at 07:57, 1 November 2008 (UTC). That page has now been edited to direct users here or elsewhere, depending on what they want to discuss. Talk:Main Page will now be only for discussing the Main Page. - dcljr

What's the point?Edit

So what's the point of this wiki? For people to post questions with solutions to them, or what? —The preceding unsigned comment was added by Soapergem (talkcontribs).

Well I guess the answer has to be - whatever you want to make of it! At the moment, it's pretty inactive. The founder hasn't been around for a long time, and there isn't much here. It's just waiting for someone to take it under their wing and get it going. It should be possible to make this wiki cover all sorts of aspects of maths - from basic principles, to example questions, to help with problems, to interesting and fun aspects of maths... and I'm sure people can think of many ideas I can't. So please - jump in and see what you can make of the place -- sannse (talk) 16:29, 29 March 2006 (UTC)
Please also see Mathematics talk:Guidelines for more discussion about this. - dcljr 11:54, 28 May 2006 (UTC)
Since no one has been policing the obvious vandalism here and the founder (and only Bureaucrat) hasn't been around for a long time, I am interested in becoming an Administrator and Bureaucrat here.   — Jeff G. ツ 17:05, April 29, 2011 (UTC)
Jeff: Why not make a request to adopt the wiki here? Good luck! — SpikeToronto 22:07, April 29, 2011 (UTC)
They seem to like attempts to engage the existing Bureaucrats and Administrators, as well as sustained editing for some days, so making such a request there now would be frowned upon.   — Jeff G. ツ 04:21, April 30, 2011 (UTC)
Yes, I’ve always understood that too. However, a Wikia staffer recently recommended to another editor with little more contributions here than you the same route. This was the only reason why I also suggested it to you. Thanks! — SpikeToronto 07:58, April 30, 2011 (UTC)
I made such a request at w:Community Central:Adoption requests#Mathematics Wikia.   — Jeff G. ツ 15:12, May 8, 2011 (UTC)
It was granted.   — Jeff G. ツ 15:50, June 3, 2011 (UTC)

common.css Edit

Um, can someone with sysop privileges copy the contents of the common.css file from Wikipedia to our common.css file? I'm trying to do some table formatting, but because some of the styles I'm referencing are in the common.css file for Wikipedia, the formatting isn't working. --Braindrain0000 04:05, 21 September 2006 (UTC)

The Wikipedia version is a bit excessive. Are you sure it's worth copying all of it here? I've copied just the "wikitable" parts for now. Is that what you needed? Angela (talk) 05:59, 21 September 2006 (UTC)
Thanks. That was mainly what I was getting at anyway. --Braindrain0000 12:08, 21 September 2006 (UTC)

Ongoing Research? Edit

Is this wiki an appropriate place to collect ongoing mathematical research that does not have published sources to make it applicable to wikipedia? I'm on an email group collaboration on the [1]? Specifically I would suggest participates present their work here for evaluation by others. Tomruen 21:12, 4 October 2006 (UTC)

P.S. Is there anyway I can add external links (to wikipedia) without triggering the spam protection!?!?!? Tomruen 21:12, 4 October 2006 (UTC)

Yes, this wiki can definitely be used for that. To link to Wikipedia, just use [[Wikipedia:Article name]]. Angela talk 01:15, 5 October 2006 (UTC)

Thanks Angela. A few more questions please, at your convenience! Thanks!

  1. Is it possible to reference(view!) pictures from wikipedia too? Tomruen 18:53, 5 October 2006 (UTC)
  2. ALSO, I tried a "#REDIRECT [[Wikipedia:<ariticle_name>]]", and it almost worked, but doesn't automatically redirect. Is this possible? Tomruen 19:10, 5 October 2006 (UTC)
  3. Also, I tried uploading a Wikipedia:VRML file, and it says "Upload warning ".wrl" is not a recommended image file format." (Not recommended seems to imply NOT allowed!) What formats ARE allowed? Tomruen 22:39, 5 October 2006 (UTC)
  4. When uploading an image, the summary text does not seem to be added to the edit or discussion text. Is there a problem here? Tomruen 22:44, 5 October 2006 (UTC)
  1. If you want to use images from Wikipedia, you need to upload them here (to avoid stealing their bandwidth)
  2. Cross-wiki redirects are disabled. They're very confusing to people who follow what looks like an internal link and end up on a different wiki, sometimes without noticing. They're also harder to revert if created by a vandal. You need to use soft redirects instead.
  3. For security reasons, the allowed files are only gif, png, jpg, pdf, odd, xcf, svg, and ico. You can link to files externally if you can find somewhere that allows VRML uploads.
  4. The summary text seems to work normally for me. It won't show up if you're over-writing an older image, but should for new images. Where have you found this isn't working?

Scope of math wikiaEdit

I am interested in contributing material on several undergraduate topics—I've contributed successfully to PlanetMath before but I'm frequently out of my depth, plus I like the wiki model and mediawiki itself more. One thing I want to get cleared up before I start is whether it's OK to add topics on (mathematical) computer science topics, like, say, Dijkstra's algorithm or A* search.


C.hever 07:54, 19 July 2008 (UTC)

Computer science topics related to mathematics would be fine.
Localhost00 16:45, 19 July 2008 (UTC)
Well my first two articles are up (Prim's algorithm and its proof). Cheers
C.hever 07:26, 10 August 2008 (UTC)

Template functionality broken? Edit

Category:Wiki_maintenance is only linking to existent templates, as if they were non-existent. What's going on? --Jesdisciple (talk) 01:59, 22 October 2008 (UTC)

I'm not sure what you mean. Only the templates most directly related to wiki maintenance tasks are listed in that category. Category:Templates is a more complete list. - dcljr 00:28, 30 October 2008 (UTC)
When a page attempts to transclude a non-existent template, it looks like Template:Non-existent template. The same thing was occurring for Template:Tl and Template:Maintenance_tasks (these are ordinary links), except the links were blue (and I think that was the only page which showed the problem). Whatever was causing it seems to have cleared up now. --Jesdisciple (talk) 12:56, 30 October 2008 (UTC)
Must've been a momentary server problem. - dcljr 05:18, 1 November 2008 (UTC)

New skinEdit


Several months ago, Wikia released a new site skin called Monaco. The new skin features tools which make it much easier for visitors to find content and edit it. You can read all about Monaco here. As you can read on that page, while you will still be able to select Monobook (this wiki's current default skin) as the skin you personally use to view the site (via Special:Preferences), we are no longer able to support Monobook as a default skin for anonymous visitors. So, we need to change the default skin to Monaco.

There are a number of pre-built themes for Monaco. Check out how the homepage looks in Sapphire, Jade, Slate, Smoke, Beach, and Brick, and let me know which one you like best. In addition to those pre-built themes, you can build your own custom themes as well. Check out the custom themes on the Shaiya Wiki and the Diablo Wiki. You can learn about customizing the theme, menus and other aspects of Monaco here.

Take a look at that information, and let me know which theme you think might work best. We need to change the skin by Friday, October 31st, so I am here to make that transition as easy as possible. Let me know if you have any questions, or if I can help in any way.

Thanks! --KyleH@Wikia (talk) 18:31, 29 October 2008 (UTC)

Hang on... - dcljr 00:29, 30 October 2008 (UTC)
I'd say my top choices would be Sapphire and Jade, followed by Smoke. Personally, I don't care for the other, darker themes. Hopefully the other admins here can weigh in on this before the switch (I've left messages for them). - dcljr 06:04, 30 October 2008 (UTC)
I like the Sapphire, Smoke, and Slate. I would like to see a new logo in the upper left, should anybody be interested in contributing one.Localhost00 06:17, 30 October 2008 (UTC)
I set the theme to Sapphire for now. If you would like to change it to something else, an admin can do that via the option at the bottom of the Skin tab in Special:Preferences. --KyleH@Wikia (talk) 18:07, 31 October 2008 (UTC)

Main Page discussion Edit

As mentioned above, Talk:Main Page is now reserved for discussing the Main Page only. Because of the recent changes to the site-wide skin, we might want to consider redesigning the Main Page. - dcljr 07:58, 1 November 2008 (UTC)

Logo redesign Edit

I've also created a page to discuss redesigning this wikia's logo. - dcljr 08:18, 1 November 2008 (UTC)

Calculator Edit

How about a wiki-based calculator? This will be similar to the other online calculators out there, but this time not based on Java or JS but on the wiki format itself, i.e. using ParserFunctions, especially #expr. --koイsuru (talk) 11:50, 11 March 2009 (UTC)

Some policy questions Edit

I just joined This past spring I attempted to add some proofs to a couple of mathematical articles on Wikipedia, but editors there told me Wikipedia doesn't do proofs. So, I moved on. I then decided to write a book on differential equations and began working on Wikibooks. However, it has become obvious that Wikibooks has some issues with rendering technical books. Specifically, there is no way to auto-number sections in a way that works across multiple wiki pages. I have suggested some ways to fix that problem, but it will probably require the use of the Labeled Section Transclusion extension (which is stable) and also the development of another extension. Given past history, this isn't going to happen on the wikimedia servers in a reasonable amount of time (a request for string functions was first made in 2006 and they still don't have that extension installed and may never get it installed). So, I am once again looking for alternatives.

That brings me to the following policy questions. Is an appropriate place for a mathematics book? This would be a reference text (a handbook), not a textbook. Secondly, what is the policy on mathematical proofs? One possibility (that would save me a great deal of work) would be to put the proofs on Unfortunately, these proofs are on fairly advanced topics (the orthonormality of the Associated Legendre Functions and the orthogonality of solutions to the General Sturm-Liouville Equation). So, just plopping them somewhere on this site would probably not be very useful. However, instead of writing a book, I could import some text on Associated Legendre Functions and the General Sturm-Liouville Equation from Wikipedia and then add the proofs. Is this something that would conform to policy? Finally, if the book option is the best (in terms of this site's policy), what is the policy on developing and deploying extensions that support section auto-numbering on texts longer than a single article? Dnessett 22:46, 30 June 2009 (UTC)

Here are my responses, which are largely Just My Opinion, since we haven't hammered out any firm policy decisions yet. And, despite the fact that I'm an administrator, I don't really have any more authority than any other editor around here...
  1. This wiki(a) is pretty much whatever people want to make it — as long as it's related to mathematics, correct information, and, well, not "completely useless" (keeping in mind that any user might have to struggle a bit to convince other editors that their ideas are worth pursuing). So, yes, making a book here would be fine, as long as it doesn't interfere with other uses of the wiki (e.g., page title conflicts). As you pointed out, the way articles are named and linked to in MediaWiki makes it very difficult to make a self-contained book with nice "internal links" between pages in the context of a larger, more general wiki. Of course, if "all you want" is to write a math book, doing it purely in LaTeX (which is freely available for most popular computer platforms) is by far a better solution than dealing with any kind of wiki.
  2. Proofs are fine (they're mathematics, after all). Only problem is, anyone can come along after you and alter the proof (same for every page, of course). So thinking you can "save work" by putting something here might be misguided: you might find yourself spending more time correcting other people's changes (/vandalism) than if you put it somewhere else that you have more control over. For the record, placing something in your userspace (like your Sandboxes) might afford it slightly more "protection" against other users' edits — if not de jure (stuff in your userspace is still licensed CC-BY-SA and thus subject to merciless editing by anyone), at least by convention (most legitimate editors will leave non-talk pages in other people's userspaces alone for the most part). See also the remarks about the user namespace at Mathematics:Namespaces.
  3. The fact that something is very advanced is not a reason to not have it here; it just makes it harder to find other editors who understand it. See previous remark. (Actually, if all this wiki consisted of was legitimate mathematical content that has been removed from Wikipedia because it was "too advanced", "not of general interest" or "just a collection of raw facts", it wouldn't be a bad use for it. IMO.)
  4. The fact that something is "okay" now doesn't necessarily mean that it will be okay forever. In other words, we can't guarantee we'll host something here indefinitely (especially if we start to work out actual policies for this wikia).
  5. As for using Wikipedia content, now that Wikia has changed to CC-BY-SA and Wikipedia is dual-licensed, we actually share the CC-BY-SA license. Still, to comply with that license, you have to credit Wikipedia for any copied text (citing "adapted" information from Wikipedia is also a good idea). Adding a reference pointing back to the Wikipedia article(s) is sufficient. If an entire article is heavily adapted from a Wikipedia original, you might want to leave a message on the talk page saying so. (Wholesale cut-and-paste jobs, by the way, may be deleted by a disapproving administrator.)
  6. Finally, as far as extensions go, you'll probably have to take that up with a Central Wikia staff member (User:Sannse and User:Angela are such individuals who have been known to edit this wikia).
I realize you probably know many of these things, but I figured I'd say them anyway, "just for the record"... - dcljr 04:53, September 17, 2009 (UTC)

How can I create a sister wiki of Mathematics Wikia in Romanian? Edit

I try to create How can I correlate it with Mathematics Wikia? Nicolae Coman 16:48, August 28, 2011 (UTC)

That would be great Nicolae! Only, I do not know how to tell you to do it. The best place to find out is to ask the same question at Forum:Support Requests at the Community Central Wiki. Once you have the new wiki created, then you can come back here and link this English-language wiki to it. Best of luck! — SpikeToronto 18:28, August 28, 2011 (UTC)
Thank you for the answer. I already created Math_Wiki in Romanian language. And another question: How can I modify the template of the page, in order to replace the letter W at the top of the page with an avatar, a mathematical symbol? Nicolae Coman 19:27, August 28, 2011 (UTC)
You might want to try asking at the Logo Creation Wiki. Hope that helps. — SpikeToronto 20:18, August 28, 2011 (UTC)

【1 paradox】Why 0.999... is not equal to 1? Edit

Written in 2012

The current mathematic theory tells us, 1>0.9, 1>0.99, 1>0.999, ..., but at last it says 1=0.999..., a negation of itself. So it is totally a paradox, name it as 【1 paradox】. You see this is a mathematic problem at first, actually it is a philosophic problem. Then we can resolve it. Because math is a incomplete theory, only philosophy could be a complete one. The answer is that 0.999... is not equal to 1. Because of these reasons:

1. The infinite world and finite world.

We live in one world but made up of two parts: the infinite part and the finite part. But we develop our mathematic system based on the finite part, because we never entered into the infinite part. Your attention, God is in it.

0.999... is a number in the infinite world, but 1 is a number in the finite world. For example, 1 represents an apple. But then 0.999...? We don't know. That is to say, we can't use a number in the infinite world to plus a number in the finite world. For example, an apple plus an apple, we say it is 1+1=2, we get two apples, but if it is an apple plus a banana, we only can say we get two fruits. The key problem is we don't know what is 0.999..., we can get nothing. So we can't say 9+0.999...=9.999... or 1, etc.

We can use "infinite world" and "finite world" to resolve some of zeno's paradox, too.

2. lim0.999...=1, not 0.999...=1.

3.The indeterminate principle.

Because of the indeterminate principle, 1/9 is not equal to 0.111....

For example, cut an apple into nine equal parts, then every part of it is 1/9. But if you use different measure tools to measure the volume of every part, it is indeterminate. That is to say, you may find the volume could not exactly be 0.111..., but it would be 0.123, 0.1142, or 0.11425, etc.

Now we end a biggest mathematical crisis. But most important is this standpoint tells us, our world is only a sample from a sample space. When you realized this, and that the current probability theory is wrong, when you find the Meta-sample-space, you would be able to create a real AI-system. It will indicate that there must be one God-system in the system, which is the controller. Look our world, there must be one God, as for us, only some robots. Maybe we are in a God's game, WHO KNOWS?

You are free to discuss your interpretation at but please read the associated article first. Philosophy is out of scope for this wiki.   — Jeff G. ツ 12:38, March 15, 2012 (UTC)
