Structure files[edit]

Your rv's are fine with me. I got their names from listing in Category:Chemical pages with an eponymous image available, I concluded by their name only. Do you think we can remove that category altogether? Or does it still have a function? -DePiep (talk) 23:26, 18 December 2014 (UTC)

The category is fine, but before adding an image found on Commons, some basic investigations are needed. At least the article itself, its talk page and history need to be checked. What about placing a warning onto the category page? BTW: I nominated these inappropriate structures for deletion. --Leyo 23:46, 18 December 2014 (UTC)
Go ahead, you know what the warning should sound like. It's not my home territory, so I'll leave it alone. btw, another option is to add a comment in the article (chembox): <!-- file xyz.svg is not correct here -->. Or, I can add a parameter |rejected_file=xyz.svg to {chembox}, to with encoded effect that that page will not appear in the category anymore. Just some ideas. -DePiep (talk) 23:52, 18 December 2014 (UTC)
I added a warning. You may want to improve the wording.
For cases where the file on Commons cannot be moved (did it in one case) or deleted (two potential cases), it may be a good idea to add a hidden comment to the chembox. --Leyo 01:26, 19 December 2014 (UTC)

Minus sign in superscripts[edit]

No slight to your efforts, but would it possible to ask a bot owner or AWB people to include it in some general fixes? Those edits are really cluttering my watchlist, hiding vandalism. Cheers. Materialscientist (talk) 02:06, 11 February 2015 (UTC)

As interwiki links are now hosted on Wikidata, there are fewer bot edits. Hence, I guess that it would take a long time to have everything fixed. Certain pages (example) had not been fixed for up to a decade. I would not mind if you asked on WP:BOTR for this task to be done.
To unclutter your watchlist, you may just activate LogsFilter
mw.loader.load( '//' );
or temporarily hide registered users (BTW: too bad en.wikipedia did not activate sighted revisions). It's also useful for other tasks. For some reasons, it's not yet a gadget here. --Leyo 10:36, 11 February 2015 (UTC)
Would you also consider using Template:val in your fixes to show scientific notation, as I've just done in Probability density function? Tayste (edits) 21:45, 12 February 2015 (UTC)
I prefer to keep the source text simple. --Leyo 22:07, 12 February 2015 (UTC)
Please can you explain why you are making this change? Xxanthippe (talk) 23:24, 12 February 2015 (UTC).
Are you asking me or Tayste? --Leyo 23:35, 12 February 2015 (UTC)
I am asking you why you made the change in Surface forces apparatus. Best wishes, Xxanthippe (talk) 23:49, 12 February 2015 (UTC).
Changing dash 8 to minus 8. --Leyo 23:55, 12 February 2015 (UTC)
Thanks. Xxanthippe (talk) 00:33, 13 February 2015 (UTC).
The fix in Plasma cosmology is very much appreciated, and something in all previous edits that I didn't spot. It seems this error was likely slipped in during some continuous edits, as the page has a history of dispute. Cheers. Arianewiki1 (talk) 22:30, 13 February 2015 (UTC)
There are a few other pages that may need being fixed. --Leyo 20:11, 15 February 2015 (UTC)

File:Gigi altro.jpg[edit]

Can you help with this file? It says that the source is de:Datei:Gigi altro.jpg, and Special:Log reveals that German Wikipedia has had two files with that name. The most recent one (by de:User:Jenson P) seems to be the one on Commons under the same name, and the one on English Wikipedia is presumably the one uploaded by de:User:Aquazurra. That one was deleted in 2008 for the reason 'Seit mindestens 14 Tagen ohne korrekte Lizenzierung'. The upload log summary says 'Quelle: privat' which I presume means 'own work' (although it also could mean that the user just owns a copy of a photograph taken by someone else) and the upload log also mentions de:Template:Bild-GFDL, meaning that the file had a copyright tag.

Was the 2008 deletion on German Wikipedia correct? If so, then the file should probably be nominated for deletion on English Wikipedia too. --Stefan2 (talk) 18:15, 29 March 2015 (UTC)

Your analysis is correct. The file was also deleted on Commons. I deleted it here straight away. --Leyo 19:02, 29 March 2015 (UTC)
  • Another image with problems: File:Güstrow Schloss.jpg, sourced to de:Datei:Güstrow Schloss.jpg. de:Special:Log says that the file has been deleted as it was available on Commons under the same, but Commons has a different picture of the same castle. --Stefan2 (talk) 18:24, 29 March 2015 (UTC)
    The file on Commons is that one that was uploaded to de.wikipedia in 2004. I don't know where the en.wikipedia version came from. --Leyo 19:05, 29 March 2015 (UTC)


WRT to SAICM Category:Chemical substances is not ideal but it is an improvement. (talk) 23:29, 24 July 2015 (UTC)

SAICM is certainly NOT a chemical substance! --Leyo 23:44, 24 July 2015 (UTC)
I know that. There needs to be a category for the miscellaneous stuff in Category:Chemical substances. Category:Chemical policy or sumthing? (talk) 01:22, 25 July 2015 (UTC)
No, only actual chemical substances may be put into Category:Chemical substances and its subcategories. SAICM or its category need to be outside of this category tree, but inside of the chemistry category tree (and the Category:Public policy tree). --Leyo 19:32, 25 July 2015 (UTC)


In chemistry related to Wikipedia:Files for deletion/2015 August 6#File:Demercuration2.gif, could I get your advice at commons:Commons talk:WikiProject Chemistry#Demercuration mechanism...need German help? DMacks (talk) 02:11, 7 August 2015 (UTC)

I've previously noticed your question there. Since I cannot answer it, I asked for help on de.wikipedia and e-mailed the uploader. --Leyo 22:45, 7 August 2015 (UTC)
Thanks! My ability to write German is zero, but I will watchlist that page. DMacks (talk) 20:21, 8 August 2015 (UTC)


Why should the Persondata remain, it doesn't exist anymore. It was rendered obsolete by Infobox and DEFAULTSORT, which serve it's purpose. Compassionate727 (talk) 17:55, 15 August 2015 (UTC)

I was not aware of this recent change, sorry. --Leyo 22:56, 15 August 2015 (UTC)

Please see the latest[edit]

…at the discussion at the Infobox page, on how to deal with data and references, here [1]. Cheers, Le Prof

The Talk sections DePiep deleted have been restored. Your comments invited and welcome. Le Prof Leprof 7272 (talk) 01:44, 19 August 2015 (UTC)
The discussion length has grown a lot. It's kind of hard to get the main points out of it. --Leyo 23:09, 20 August 2015 (UTC)

Your voice needed in this discussion[edit]

I re-entered this discussion, in part because broadly experienced voices like yours had joined in. If time permits, consider returning to this it? It is about about Chembox sourcing? Cheers. Le Prof Leprof 7272 (talk) 18:42, 21 August 2015 (UTC)

Disambiguation link notification for September 19[edit]

Hi. Thank you for your recent edits. Wikipedia appreciates your help. We noticed though that when you edited Multimedia fugacity model, you added a link pointing to the disambiguation page Emissions (check to confirm | fix with Dab solver). Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ • Join us at the DPL WikiProject.

I beg you nicely and politely[edit]

The benzene structure of Dewar and Ladenburg were 3D and my midterm assignment was to add the 3D struture, please understand me. — Preceding unsigned comment added by ShinRyu Forgers (talkcontribs) 04:39, 7 November 2015 (UTC)

Leyo, this person also posted on my talkpage, where I responded in detail about the chemical problems ("wrong", not just redundant/lower-quality compared to other available). This is the second such enthustistic but seemingly out-of-his-depth (and using similar structure-misgeneration approach) I have encountered this week. Wonder if there are more in this class? DMacks (talk) 05:47, 8 November 2015 (UTC)
  • It is not the fault of Wikipedia editors that your teacher does not seem to have a clue about Wikipedia. Otherwise (s)he would not have given you such an assignment. See Wikipedia:Student assignments for more information.
  • Key articles such as benzene can't be improved easily, since they are already on a high level. Niche articles, on the other hand, may be improved much more easily.
  • If you intend to create high-quality ball-and-stick models of molecules (example), please read how to make 3D images of molecules.
  • In any case, upload your files in much higher resolutions. 350 × 300 pixels is way too small, especially for print.

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.
