Math help

Hey Onar. Can you do your magic and format the formulas and numbers on the article Akhmim Wooden Tablet, to make it look pretty like you did for Cahn-Hilliard equation? I tried to do it myself, but I almost killed the article. -Taco325i 16:01, 24 January 2007 (UTC)

Thanks for your help on the article, it looks great! -Taco325i 12:11, 26 January 2007 (UTC)

Thanks

Thank you for the Cahn-Hilliard equation article, which was sorely missing. Oleg Alexandrov (talk) 03:36, 25 January 2007 (UTC)

The GNS inequality

Hi.

A constant non-zero function is not a continuously differentiable function with compact support, as its support is the whole $R^{n}$. Also see [1]. Probably, you meant the Poincare inequality. (Igny 20:55, 13 May 2007 (UTC))

Hi,

The way I see it, there is a classical GNS inequality, and there are GNS-type inequalities, which are, basically, some variations, generalizations, or adaptations to particular conditions. If you find enough material with references, may be the GNS inequalities deserve a separate article where different variations and their relationships to other inequalities are discussed.

Rayleigh–Taylor instability

Hello Onaraighl. Thanks for adding the linear stability analysis. One of the key points for inclusion on Wikipedia is verifiability, see WP:V. On controversial subjects, it happens that each statement is followed by one or more references. Now this stability analysis is of course not controversial, but in my opinion it still requires some references at key points in the analysis, e.g. where important assumptions regarding the mathematical-physical modelling are made and for the stated end results. The main points should also be verifiable for people not well aquainted with the subject. References should be more specific than referring to an (excellent reference) book of over 600 pages, e.g. to page numbers or small ranges of page numbers, see WP:CITE. This does not have to be cumbersome, using the <ref name=ID> construct for page number references (assuming the same pages are referenced several times, see WP:REFNAME) and adding Chandrasekhar's book to the References.

Another point is readability as an encyclopedic article, see Wikipedia:Make technical articles accessible and Wikipedia:Manual of Style (mathematics). More readers may be interested in the assumptions (as well as the reasoning leading to them) and end results of the linear stability analysis, than in its derivation. The derivation as given is nice and of of interest for those looking for it, so it should be retained in some form without losing readers not interested in the derivation and much mathematics. There are several solutions for this, see e.g. before-mentioned guides. Some options are: put the derivation itself in a collapsed table (see e.g. Bernoulli's principle), or make a separate article on the stability analysis and only put the key results in this article (see e.g. Derivation of the Navier–Stokes equations).

Do you want to work on this yourself? Or shall we do this together, or are you not interested (in which case I will start with this)? Best regards, Crowsnest (talk) 10:46, 29 June 2008 (UTC)

Proposed deletion of Turbulence modeling

The article Turbulence modeling has been proposed for deletion because of the following concern:

Page has multiple issues. Information on page is already contained on pages such as computational fluid dynamics, turbulence, Reynolds-averaged Navier-Stokes equations, large eddy simulation, etc. Deletion of this page will prevent information creep, scattered information, and redundant efforts related to Wikipedia's coverage of turbulence and turbulence modeling. See Talk page for a vote on this issue.

While all contributions to Wikipedia are appreciated, content or articles may be deleted for any of several reasons.

You may prevent the proposed deletion by removing the {{dated prod}} notice, but please explain why in your edit summary or on the article's talk page.

Please consider improving the article to address the issues raised. Removing {{dated prod}} will stop the proposed deletion process, but other deletion processes exist. The speedy deletion process can result in deletion without discussion, and articles for deletion allows discussion to reach consensus for deletion.

Hi Onaraighl, I noticed your comments on the Talk page at Turbulence models so I thought I'd leave this message here. I've proposed the article be deleted, you can see my justification and vote on the issue at the Turbulence models talk page. Hope to hear from you there. --Charlesreid1 (talk) 10:09, 6 November 2010 (UTC)

Notification of automated file description generation

Your upload of File:Blasius1.PNG or contribution to its description is noted, and thanks (even if belatedly) for your contribution. In order to help make better use of the media, an attempt has been made by an automated process to identify and add certain information to the media's description page.

This notification is placed on your talk page because a bot has identified you either as the uploader of the file, or as a contributor to its metadata.

• Another one of your uploads, File:Channel one phase.png, has also had some information automatically added. If you get a moment, please review the bot's contributions there as well. Thanks! Message delivered by Theo's Little Bot (opt-out) 14:23, 22 April 2014 (UTC)

ArbCom elections are now open!

Hi,
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.
