Hello Dmr2 and welcome to Wikipedia! Hope you like it here, and stick around.

Here are some tips to help you get started:

Good luck!

This media may be deleted.

Thanks for uploading Image:Ben Green, Mathematician.jpg. I notice the 'image' page currently doesn't specify who created the content, so the copyright status is therefore unclear. If you have not created this media yourself then you need to argue that we have the right to use the media on Wikipedia (see copyright tagging below). If you have not created the media yourself then you should also specify where you found it, i.e., in most cases link to the website where you got it, and the terms of use for content from that page.

If the media also doesn't have a copyright tag then you must also add one. If you created/took the picture, audio, or video then you can use {{GFDL}} to release it under the GFDL. If you believe the media qualifies as fair use, please read fair use, and then use a tag such as {{Non-free fair use in|article name}} or one of the other tags listed at Wikipedia:Image copyright tags#Fair_use. See Wikipedia:Image copyright tags for the full list of copyright tags that you can use.

If you have uploaded other media, please check that you have specified their source and copyright tagged them, too. You can find a list of 'image' pages you have edited by clicking on the "my contributions" link (it is located at the very top of any Wikipedia page when you are logged in), and then selecting "Image" from the dropdown box. Note that any unsourced and untagged images will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. Thank you. cohesiontalk 07:59, 15 February 2006 (UTC)[reply]

Hi, Dmr2, did you write this?: "For a two-dimensional surface, there is (up to symmetries) only one non-zero component of the Riemann tensor, , which is equal to the determinant of the metric tensor ." I take it that last bit was a brain blip :-/ ---CH 13:58, 19 June 2006 (UTC)[reply]

Hi, no I didn't write it. I just corrected the English without thinking about whether it made sense! I have tried to amend it so that now it does make sense. --Dmr2 10:24, 20 June 2006 (UTC)[reply]

Hi

[edit]

I noticed that you correct my deficient english and I thank you. But I also want to ask (respectfully) about the meaning of the sentence above:

I take it that last bit was a brain blip.

Further, what about the components for 3-manifolds? Do you know of something basic about them, worth for the Riemann curvature tensor article?

Thanks again!--Juan Marquez 02:12, 20 June 2006 (UTC)[reply]

Hi Juan. In think "brain blip" is referring to forgetting the Ricci scalar. For surfaces, should be Rg/2, not g.
I'm not sure what we could write about the Riemann tensor for 3-manifolds other than that there are 6 independent components, which can be thought of as the components of the Ricci tensor, . --Dmr2 10:33, 20 June 2006 (UTC)[reply]


could you please tell us how are organized these $R_{ijkl}$ for a generic 3-manifold and any other meaning about these functions?

Request for edit summary

[edit]

When editing an article on Wikipedia there is a small field labeled "Edit summary" under the main edit-box. It looks like this:

Edit summary text box

The text written here will appear on the Recent changes page, in the page revision history, on the diff page, and in the watchlists of users who are watching that article. See m:Help:Edit summary for full information on this feature.

Filling in the edit summary field greatly helps your fellow contributors in understanding what you changed, so please always fill in the edit summary field, especially for big edits or when you are making subtle but important changes, like changing dates or numbers. Thank you. – Oleg Alexandrov (talk) 18:20, 31 July 2006 (UTC)[reply]

trouble with Dead-End Pages?

[edit]

you made one edit [1] that seemed to restore a lot of stuff recently deleted. Finger trouble?

I restored it, anyway - but if there was one you wanted to delete, better check again. --Alvestrand 18:02, 8 August 2006 (UTC)[reply]

Thanks, I think I must have edited a previous version! --Dmr2 10:30, 9 August 2006 (UTC)[reply]

beta-functions

[edit]

Dear dmr2, I have recently started editing wikipedia articles, focussing particularly on theoretical physics. I thought you might like to look over my recent contributions on beta-functions, and also the Landau pole and asymptotic freedom in Coupling constant. --Jpod2 12:20, 9 August 2006 (UTC)[reply]

Hi Jpod2. Welcome to Wikipedia. You seem to have got the hang of things ;) --Dmr2 13:47, 9 August 2006 (UTC)[reply]

Re: Dilaton->Dilation

[edit]

Hi, your bot incorrectly changed dilaton to dilation in Chiara Nappi. Dmr2 11:02, 13 September 2006 (UTC)[reply]

My apologies. I thought I knew a bit of physics, but I'd never heard of dilatons. Ah, the wacky world of string theory; although I guess I've learned something new for today! :) Thanks for catching that. Cheers, CmdrObot 20:45, 13 September 2006 (UTC)[reply]

Oops

[edit]

My note about the "Ave verum corpus" came from notes from a music history class I took, but based on a quick internet check I no longer believe it is correct. Thanks for pointing that out. Geriguiaguiatugo 14:04, 22 September 2006 (UTC)[reply]

Survey Invitation

[edit]

Hi there, I am a research student from the National University of Singapore and I wish to invite you to do an online survey about Wikipedia. To compensate you for your time, I am offering a reward of USD$10, either to you or as a donation to the Wikimedia Foundation. For more information, please go to the research home page. Thank you. --WikiInquirer 11:36, 9 March 2007 (UTC)talk to me[reply]

Motto of the day

[edit]

Hello, I notice you're using one of the {{motd}} templates, run by Wikipedia:Motto of the day. You may have noticed that some of the mottos recently have been followed by a date from 2006, or on occasion simply "Wikipedia, the free encyclopedia". The reason for this is that Motto of the day is in some very serious need of help. Participation in the project, which has never been especially high, has dropped considerably over this past summer, to the point we have had several days where no motto was scheduled to appear at all. Over the past several weeks, I've been the only editor scheduling mottos at all, but there aren't enough comments on some of these mottos to justify their use. If we do not get some help - and soon - your daily mottos will stop. In order for us to continue updating these templates for you, we need your help.

When you get a chance between your normal editing, could you stop by our nominations page and leave a few comments on some of the mottos there, especially those that do not have any comments yet? This works very simply; you read a motto, decide whether or not you like it, and post your opinion just below the motto. That's it - no experience required, just an idea of what you personally like and what you feel reflects Wikipedia and its community. If you do have past experience with the project, then please close some of the older nominations once they've got a decent consensus going. There are directions on the nominations page on how to do this.

If you have any questions, please let me know, or post on the project's talk page. I'm looking forward to reading your comments on the suggested mottos, and any additional suggestions you'd like to make. Until then, happy editing! Hersfold (t/a/c) 01:38, 4 September 2008 (UTC)[reply]

Image licensing

[edit]

Hey there...

I am trying to clean up some of the images with minor licensing issues and I came across Image:Stu1.png which is only used on your userpage. If you are going to use the image, could you go and fix the licensing on the image page and be clear about releasing the image under a GFDL license (or another free license). Thanks. If you have any questions, please drop me a note on my talk page. --Jordan 1972 (talk) 14:58, 11 October 2008 (UTC)[reply]

All files in category Unclassified Chemical Structures listed for deletion

[edit]

One or more of the files that you uploaded or altered has been listed at Wikipedia:Files for deletion. Please see the discussion to see why this is (you may have to search for the title of the image to find its entry), if you are interested in it/them not being deleted. Thank you.

File:Stu1.png needs authorship information

[edit]
Dear uploader:

The media file you uploaded as File:Stu1.png appears to be missing information as to its authorship (and or source), or if you did provide such information, it is confusing for others trying to make use of the image.

It would be appreciated if you would consider updating the file description page, to make the authorship of the media clearer.

Although some images may not need author information in obvious cases, (such where an applicable source is provided), authorship information aids users of the image, and helps ensure that appropriate credit is given (a requirement of some licenses).

  • If you created this media yourself, please consider explicitly including your user name, for which: {{subst:usernameexpand|Dmr2}} will produce an appropriate expansion,
    or use the {{own}} template.
  • If this is an old image, for which the authorship is unknown or impossible to determine, please indicate this on the file description page.
If you have any questions please see Help:File page. Thank you. Sfan00 IMG (talk) 14:18, 30 December 2011 (UTC)[reply]

If this is the first article that you have created, you may want to read the guide to writing your first article.

You may want to consider using the Article Wizard to help you create articles.

A tag has been placed on Johannes Spech requesting that it be speedily deleted from Wikipedia. This has been done under section A7 of the criteria for speedy deletion, because the article appears to be about a person, organization (band, club, company, etc.) or web content, but it does not indicate how or why the subject is important or significant: that is, why an article about that subject should be included in an encyclopedia. Under the criteria for speedy deletion, such articles may be deleted at any time. Please see the guidelines for what is generally accepted as notable.

If you think that this notice was placed here in error, contest the deletion by clicking on the button labelled "Click here to contest this speedy deletion". Doing so will take you to the talk page where you will find a pre-formatted place for you to explain why you believe the page should not be deleted. You can also visit the page's talk page directly to give your reasons, but be aware that once tagged for speedy deletion, if the page 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 page that would render it more in conformance with Wikipedia's policies and guidelines. If the page is deleted, you can contact one of these administrators to request that the administrator userfy the page or email a copy to you. Gsingh (talk) 06:40, 3 January 2012 (UTC)[reply]

Help Request

[edit]

You may have noticed over the past few days that the MOTD that you link to on your user page has simply displayed a red link. This is due to the fact that not enough people are reviewing pending MOTDs here. Please help us keep the MOTD template alive and simply go and review a few of the MOTDs in the list. That way we can have a real MOTD in the future rather than re-using (This space for rent). Any help would be appreciated! –pjoef (talkcontribs) 08:57, 7 March 2012 (UTC)[reply]

Motto of the Day Help Request April 2014

[edit]
Today's motto...

Every good encyclopedia has gnus, GNUs, news, Wales, Wales, and Whales!


Nominate one today!

Motto of the Day (WP:MOTD) is in a state of emergency and really needs your help! There are not enough editors who are reviewing or nominating mottos at Wikipedia:Motto of the day/Nominations/In review, and this probably means that you will notice a red link or “This space for rent” as our mottos for the next weeks and months.

Please take a moment to review the nominations and nominate your own new mottos at Wikipedia:Motto of the day/Nominations/In review and Wikipedia:Motto of the day/Nominations/'Specials. Any help would be appreciated! MediaWiki message delivery (talk) 09:13, 29 April 2014 (UTC)[reply]

This message has been sent by pjoef on behalf of Motto of the Day to all editors of the English Wikipedia who are showing MOTD's templates on their pages, and to all the participants to MOTD: (page, template, and category).

Hi, I'm Boleyn. Dmr2, thanks for creating Felipe Rodríguez (composer)!

I've just tagged the page, using our page curation tools, as having some issues to fix. This has been tagged for 3 issues.

The tags can be removed by you or another editor once the issues they mention are addressed. If you have questions, you can leave a comment on my talk page. Or, for more editing help, talk to the volunteers at the Teahouse.
