Math 2.0[edit]

We finally managed to improve Math rendering within Wikipedia Now, I'd like to collect user feedback and see which features are still missing after Math 2.0. Please let me know if you consider to help with that. Especially with the communication to the community. --Physikerwelt (talk) 20:25, 17 October 2014 (UTC)

I don't know if you're using any of the mailing lists, but this just came through so I wanted to copy it over to you (sorry for my poor formatting):

Dear Wikipedians,

We'd like to announce a major update of the Math (rendering) extension.

For registered Wikipedia users, we have introduced a new math rendering mode using MathML, a markup language for mathematical formulae. Since MathML is not supported in all browsers [1], we have also added a fall-back mode using scalable vector graphics (SVG).

Both modes offer crisp rendering at any resolution, which is a major advantage over the current image-based default. We'll also be able to make our math more accessible by improving screenreader and magnification support.

We encourage you to enable the MathML mode in your Appearance preferences. As an example, the URL for this section on the English Wikipedia is:

For editors, there are also two new optional features:

1) You can set the "id" attribute to create math tags that can be referenced. For example, the following math tag

can be referenced by the wikitext

mass energy equivalence

This is true regardless of the rendering mode used.

2) In addition, there is the attribute "display" with the possible values "block" or "inline". This attribute can be used to control the layout of the math tag with regard to centering and size of the operators. See for a full description, of this feature.

Your feedback is very welcome. Please report bugs in Bugzilla against the Math extension, or post on the talk page here:

All this is brought to you by Moritz Schubotz and Frédéric Wang (both volunteers) in collaboration with Gabriel Wicke, C. Scott Ananian, Alexandros Kosiaris and Roan Kattouw from the Wikimedia Foundation. We also owe a big thanks to Peter Krautzberger and Davide P. Cervone of MathJax for the server-side math rendering backend.


Gabriel Wicke (GWicke) and Moritz Schubotz (Physikerwelt)

[1]: Currently MathML is supported by Firefox & other Gecko-based browsers, and accessibility tools like Apple's VoiceOver. There is also partial support in WebKit.

I hope this is helpful to you! --Rdicerb (WMF) (talk) 20:53, 23 October 2014 (UTC)

Edits to Hurwitz problem[edit]

Hi, I thought I'd expand the Hurwitz problem page to include some bounds on possible admissible triples (r,s,n). Checking this is okay with you, since you seem to be the main contributor. Tkmharris (talk) 12:58, 18 February 2015 (UTC)

ArbCom elections are now open![edit]

You appear to be eligible to vote in the current Arbitration Committee election. The Arbitration Committee is the panel of editors responsible for conducting the Wikipedia arbitration process. It has the authority to enact binding solutions for disputes between editors, primarily related to serious behavioural issues that the community has been unable to resolve. This includes the ability to impose site bans, topic bans, editing restrictions, and other measures needed to maintain our editing environment. The arbitration policy describes the Committee's roles and responsibilities in greater detail. If you wish to participate, you are welcome to review the candidates' statements and submit your choices on the voting page.
