## Speedy deletion of Eigenvector slew

A tag has been placed on Eigenvector slew, requesting that it be speedily deleted from Wikipedia. This has been done under section G1 of the criteria for speedy deletion, because the page appears to have no meaningful content or history, and the text is unsalvageably incoherent. If the page you created was a test, please use the sandbox for any other experiments you would like to do. Feel free to leave a message on my talk page if you have any questions about this.

If you think that this notice was placed here in error, you may contest the deletion by adding {{hangon}} to the top of the page that has been nominated for deletion (just below the existing speedy deletion or "db" tag), coupled with adding a note on the talk page explaining your position, but be aware that once tagged for speedy deletion, if the article meets the criterion it may be deleted without delay. Please do not remove the speedy deletion tag yourself, but don't hesitate to add information to the article that would would render it more in conformance with Wikipedia's policies and guidelines. Lastly, please note that if the article does get deleted, you can contact one of these admins to request that a copy be emailed to you. Dengero (talk) 13:51, 25 July 2008 (UTC)

## Proposed deletion of Eigenvector slew

A proposed deletion template has been added to the article Eigenvector slew, suggesting that it be deleted according to the proposed deletion process. All contributions are appreciated, but this article may not satisfy Wikipedia's criteria for inclusion, and the deletion notice should explain why (see also "What Wikipedia is not" and Wikipedia's deletion policy). You may prevent the proposed deletion by removing the {{dated prod}} notice, but please explain why you disagree with the proposed deletion in your edit summary or on its talk page.

Please consider improving the article to address the issues raised because even though removing the deletion notice will prevent deletion through the proposed deletion process, the article may still be deleted if it matches any of the speedy deletion criteria or it can be sent to Articles for Deletion, where it may be deleted if consensus to delete is reached.

I have removed the speedy delete tag and replaced it with the above AfD warning on the grounds that the mathematics may make sense, but the article is need of a clear explanation and references. Ben MacDui 16:14, 25 July 2008 (UTC)

## Hi

Hi! And since it appears as if you haven't been welcomed, welcome to Wikipedia! I hope you didn't interpret wrongly my removal of the section you added to Polar coordinate system for cleanup; I assure you, I meant no harm, and you contributions really are valued and help to make the encyclopedia better. I have tried to cleanup the section ([1]) to make it read better; please tell me if you are OK with this change. Thanks! — 17:17, 25 July 2008 (UTC)

p.s. There's a document called Wikipedia:Manual of Style (mathematics) that it might be good to briefly read through to avoid any further problems. — 17:19, 25 July 2008 (UTC)

## References and context

Please do not remove {{Unreferenced}} and {{context}} from the 3 axis stabilized spacecraft article. There is no reason to remove them, and the article does lack references and a clear lead. I have written a couple of sentences about its insufficient context on the article's Talk page. Feel free to write your opinion there, or ask me a question for clarification.

Thanks, « D. Trebbien (talk) 23:56, 27 July 2008 (UTC)

## Areas you might like to explore

Hi Stamcose,

I happened across Stepped nozzles, which was started by Wolfkeeper, and was inspired to think that maybe there were some WikiProjects out there that you might like to participate in.

It turns out that there are a few:

There is also a category, Category:Spacecraft stubs, which contains a whole bunch of articles to improve, if interested.

## Rotation operator (vector space)

Hello. Please notice my edits to Rotation operator (vector space). You don't need to write

$.\,$

Instead you can write

$\langle A \rangle.\,$

Michael Hardy (talk) 03:52, 3 August 2008 (UTC)

it is suggested to use the signs + - < > = | (directly)

Do you see any disadvantage?

Stamcose (talk) 07:32, 3 August 2008 (UTC)

Obviously in TeX if you want to say that x is less than y, you write
$x < y.\,$
But when you wrote
$\,$
you were not trying to say anything is less than or greater than anything. You were using "<" and ">" as angle brackets. That is incorrect. you should have written
$\langle A \rangle.\,$
I don't think the page you cite says that you should have written it the way you did. Michael Hardy (talk) 12:56, 3 August 2008 (UTC)
PS, the page you cite, http://en.wikipedia.org/wiki/Help:Formula, explicitly says the Tex code for angle brackets is \langle \rangle. Michael Hardy (talk) 12:58, 3 August 2008 (UTC)

I guess you are right. This is the intended look of this bracket! I'll change to bracket!

## Flight dynamics (satellites)

Hi. Back in 2008, you commented on the Talk page of an article that is currently named Flight dynamics (satellites). There are several discussions going on over there now and your input would be very much appreciated on each topic. Cheers. N2e (talk) 17:32, 13 December 2010 (UTC)

## Heliosynchronous orbit

Hi Stamcose. I saw your recent edit summary on Sun-synchronous orbit about the "deletion" of Heliosynchronous orbit. I basically agree.

I just looked into the status of that deletion/merger discussion and found it rather a mess. I have tried to clean up both the Talk page where the discussion has been (sort of) happening, as well as fix the link in the article-level Merge tag on Heliosynchronous orbit so that all interested editors get to the right place for the discussion.

Would appreciate you weighing in. Cheers. N2e (talk) 17:01, 3 November 2011 (UTC)

Thanks very much Stamcose for weighing in. You did it on the Talk page, which was what I suggested. Shortly after that, however, another editor nominated Heliosynchronous orbit for deletion. Please go to that deletion page and add your thoughts. N2e (talk) 15:07, 7 November 2011 (UTC)

## Edit warring at Newcomb's formula

A notice has been placed at Wikipedia:Administrators' noticeboard/Edit warring#Newcomb's formula concerning your unilateral overturning of this AfD. Jc3s5h (talk) 19:17, 6 November 2011 (UTC)

Hi there, Stamcose. As you can see above, the article was redirected as a result of a consensus from a deletion discussion. Please refrain from reverting, which goes against that consensus. If you disagree with the result of that discussion, you should go to deletion review rather than reverting yourself. Thanks, Swarm X11|11|11 19:35, 6 November 2011 (UTC)

Hello, Stamcose. You have new messages at Talk:Heliosynchronous orbit.
Message added 01:16, 9 July 2012 (UTC). You can remove this notice at any time by removing the {{Talkback}} or {{Tb}} template.

I'm thinking of proposing an AfD for this erroneous redirect. Please weigh in on the talk page with your thoughts on yes or no, and whether one of us ought to propose AfD now, or wait a while longer. Cheers. N2e Talk:Heliosynchronous orbit N2e (talk) 01:16, 9 July 2012 (UTC)

## Asking for advice with nonconservative Lagrangian formalism

Hello, I'm a physicist. During my work I came across the 2d set of equations below. The system can both receive and lose energy. Do you think that the Rayleigh (dissipative) term is appropriate here? v0 is a constant, v(t) = sqrt(vx(t)^2+vy(t)^2). Thanks! fij (talk) 10:10, 6 March 2014 (UTC)

d vx / dt = ( vx / v ) ( v0 - v ) + 1/x^2

d vy / dt = ( vy / v ) ( v0 - v )
