Please don't revoke an edit without checking

I've been away from Wikipedia for a while, but you revoked my edit a year ago on the phrase "f-dash" for the derivative.

This phrase is used in UK, Australia, and even Japan. That's 100's of millions of people. (But I admit not 100's of millions of people who understand what a derivative is!)

I obtained a degree in mathematics in Australia and never once heard the phrase "f-prime" - I'm assuming it's an American phrase.

FYI, I agree with your comment that it makes no sense to call ' a "dash". But apparently it's a thing from music notation.

Anyway, I have re-installed "f-dash" as an alternative pronunciation. Please do not revoke if you disagree. Start something in the Talk instead. Jim77742 (talk) 11:07, 14 July 2022 (UTC)

A different user asks: Please don't revoke an edit without checking - Frank Zappa Edition

You revoked an edit that basically corrected an arithmetic error stating that 62 + 57 = 122. That is obviously incorrect and I corrected it to 119. Additionally, the correct number was already on the Frank Zappa Discography page. This issue was already corrected on the page by another user, but 5 seconds of your time and some basic addition could have prevented all of this.

Please slow down and make sure your contributions or revocations are truly warranted. 107.0.197.47 (talk) 20:26, 15 July 2022 (UTC)

@107.0.197.47: Do note that the (currently) last album of the offcial discography https://www.zappa.com/music/official says "Official Release #121"—see [1]. So both 122 and 119 are likely wrong. But who cares anyway: One of these days Joe T. will pull the next release from the vault. It's pretty infinite. Don't forget to check on a daily basis so you can keep the bad number up-to-date .

Talk:Planck units

I noticed you removed a comment from Talk:Variable speed of light per the regular guidelines. A substantially identical comment was left at Talk:Planck units; I replied to that one, taking the opportunity to be a little silly, but I wouldn't object to hatting the whole section for being off-topic. XOR'easter (talk) 22:51, 22 July 2022 (UTC)

@XOR'easter:, yep, I had seen it, but as you already had replied, I decided not to remove the entry. Meanwhile someone else did that, and the user was blocked for using multiple accounts and trolling. - DVdm (talk) 08:48, 23 July 2022 (UTC)

Yes, sorry, that was me (I got logged-out mid-edit). XOR'easter, I hope you forgive removing your comment as well (and of course I could restore that part if anyone cared). JBL (talk) 17:03, 23 July 2022 (UTC)

JayBeeEll, that removal is fine with me. I wonder if someone should write up a long-term abuse report for QG, since their history of trolling and generally disruptive behavior goes back at least to 2018. XOR'easter (talk) 17:23, 23 July 2022 (UTC)

It's a reasonable idea, although I'm also not sure how useful LTA reports are in general. Unfortunately now the video is attracting assorted non-sock cranks, rather than just one sockpuppeting loon. -- JBL (talk) 23:58, 26 July 2022 (UTC)

Pretty toxic atmosphere over there... - DVdm (talk) 10:40, 27 July 2022 (UTC)

Variable speed of light is now semi-protected for a week, so maybe they'll lose interest. XOR'easter (talk) 01:31, 28 July 2022 (UTC)

... or maybe not? XOR'easter (talk) 18:23, 31 July 2022 (UTC)

Hello. I just happened to come across this conversation in my Watchlist. On the talk page of VSL the same editor whose comment was removed added a new section [2] with the same rant. They are engaging in wikilawyering, and are threatening to put editors on report. This is of course laughable (I'm chucking right now). In any case, I just wanted to let you know. ---Steve Quinn (talk) 19:31, 31 July 2022 (UTC)

Update: I decided to remove the rant [3]. Regards. ---Steve Quinn (talk) 19:48, 31 July 2022 (UTC)

Threatening to put editors on report seems to be something of a theme. "Deleting of critics of how this page is edited will be documented"! XOR'easter (talk) 19:54, 31 July 2022 (UTC)

LOL! ---Steve Quinn (talk) 21:02, 31 July 2022 (UTC)

I see they've now been blocked for 1 week. XOR'easter (talk) 23:07, 31 July 2022 (UTC)

@XOR'easter: Yes, I filed a 3RR report for which they received a (helpful) block. [4]. ---Steve Quinn (talk) 17:27, 1 August 2022 (UTC)

OK. I see by the link you provided you have already seen this. Sorry, I didn't notice your link before I posted, ---Steve Quinn (talk) 17:30, 1 August 2022 (UTC)

No worries! :-) XOR'easter (talk) 20:09, 1 August 2022 (UTC)

Remember Riggs, P.J.?

I removed seven as cite spam. Mostly different IPs. Created an article list on User:Adakiko/Cite spam. I should periodically search for "Riggs, P.J." and other variations. Cheers Adakiko (talk) 06:48, 4 August 2022 (UTC)

@Adakiko: Thanks. Yes, I remember User talk:DVdm/Archive_2022#More cite spam. Are they back at it? As I said, to be kept an eye on. - DVdm (talk) 08:46, 4 August 2022 (UTC)

Yep, adding it to one article every few weeks. Two in June, three in July, and two in August. I reverted them. Asked CircuitOne (talk · contribs) to take it to talk:causal loop. See what happens. I was watching causal loop and found the rest by searching "Riggs, P.J." ;o). Cheers Adakiko (talk) 09:08, 4 August 2022 (UTC)

Dispute Resolution Notice Board Requested

I noticed that a message you recently left to a newcomer may have been unduly harsh. Please remember not to bite the newcomers. If you see others making a common mistake, consider politely pointing out what they did wrong and showing them how to correct it. It takes more time, but it helps us retain new editors. Thank you. VQuakr (talk) 18:45, 5 October 2022 (UTC)

@VQuakr: Before I gave that warning, I had carefully reviewed all the editor's other edits, some dating back to 2020. Apart from bad grammar, most edits seem to add something to try to emphasise the role of other contributors beside Einstein to the subject of relativity. So I sensed biased editing and decided to undo the edit. Warning mode was triggered when my suspicion was confirmed by the edit summary of their revert: "In wikipedia documents about theory of relativity, "Einstein published in blabla" is stated although this fact is already famous enough and well stated in history. So, there is no problem state it here. I guess that some people reluctant to mention other scholar's achievements and want to make Einestein a super hero." Perhaps I should have added something about biased editing as well. - DVdm (talk) 08:55, 6 October 2022 (UTC)

But you get that this isn't better, right? most edits seem to add something to try to emphasise the role of other contributors beside Einstein to the subject of relativity isn't a particularly problematic editing pattern; the fact is Einstein is a little over-hyped in popular media about physics. They aren't under any editing restrictions, and in this particle case there were adding material that absolutely belonged in the lead to an article that was missing its lead (Einstein should be mentioned in the lead, too). Can you reply on the article talk page so we can move this along?

Yes, I gave them some non-template coaching about musing about other editors' motivations. VQuakr (talk) 15:58, 6 October 2022 (UTC)

Mass-energy equivalence

Hi DVdm. You are one of the principal contributors to our article Mass-energy equivalence so it would be great if you could take a look at this edit.

And if you could find time to contribute your thoughts at Wikipedia talk:WikiProject Physics#Inconsistencies related to mechanical energy it would be much appreciated. Thanks. Dolphin (t) 12:08, 29 November 2022 (UTC)

@Dolphin: I never really contributed much to that article, that is, apart from regularly doing quick anti-vandalism/spam/badgrammar/origresearch on it. I don't really have the time to look into this now. The topîc on the physics project will surely help sorting it out . Cheers - DVdm (talk) 12:52, 29 November 2022 (UTC)

Vaeiable Speed Of Light Disagreement well documented

Thank you for comments about my additions to the page Variable Speed if light.

I did in fact reference passages in six books that are well known and written by famous people. All of my additions except one support the view of Einstein, Born, and Tolman, referred to in other parts of the page. The disagreement of Peter Bergmann is well documented in his book The riddle of Gravitation, in which he argued for several pages against the Einstein view.

The disagreement is important because the Bergmann view is taught in college and the Einstein view is seldom mention, although it is well documented in the six books I referenced.

Thanks again for your reply. As always you are welcome to change my addition to the page Variable speed of light. Astrojed (talk) 20:53, 30 December 2022 (UTC)

I hadn't noticed this. Anyway, I have undone ([5]) your edit about setting ds to zero again. Not in the sources. Please stop adding wp:original research to articles. Thanks. - DVdm (talk) 16:46, 31 December 2022 (UTC)

Deleting VLS Entries You Objected To

My policy is to respect the opinions of others. I deleted my recent additions to VLS page although I believe my short entries derived from references to 7 famous books were appropriate and well enough written. I did not write my opinions or take sides in the arguments that have continued more than 50 years. Astrojed (talk) 21:59, 31 December 2022 (UTC)

@Astrojed: Thanks for this and happy 2023! - DVdm (talk) 00:09, 1 January 2023 (UTC)

The reason for removing the edit on the Wave-Particle Duality?

Hi DVdm, I am trying to update the new development on the Wave-Particle duality. Is there a reason why the edit was removed?

Thanks, Hong Hongdusocal (talk) 19:00, 9 January 2023 (UTC)

@Hongdusocal: yes, hi there. As I explained in the edit summary of my revert, I removed your edit per lack of notability. See wp:primary source and wp:recentism. When this publication is sufficiently mentioned in the relevant literature, and thus in wp:secondary sources, it might be sufficiently notable for Wikipedia. See also wp:NOT. Hope this helps. - DVdm (talk) 20:06, 9 January 2023 (UTC)

Time dilation

I do want to have some mention of the psychological sense on the time dilation page because people do use the phrase time dilation in that sense. Maybe the {{see also}} template wasnt the best choice, but I couldnt think of anything else. Would you be okay with some other type of hatnote, saying something like "for the term used in psychology, see time perception"? Thanks, —Soap— 23:15, 11 January 2023 (UTC)

@Soap: Hi there, something that suggests that the term should not be confused, would be okay, as it is done in the article Relativism:

For the physics theory, see Theory of relativity.

So, how about indeed:

For the term used in psychology, see Time perception.

or, even better:

This page is about a physical concept. For the term used in psychology, see Time perception.

And of course, the other way around in article Time perception, perhaps:

This page is about a term used in psychology. For the physical concept, see Time dilation.

Afaiac, go ahead. Cheers! - DVdm (talk) 10:12, 12 January 2023 (UTC)

Van Cittert-Zernike

Literature does NOT decide how to write Dutch names, mister. Dutch language does!!! But yes, it's a fact that you English have NO TALENT at all for foreign languages. And it seems (looking at your own actions) you are too stubborn to learn anything in this respect. So poor. Weaky3 (talk) 16:39, 11 March 2023 (UTC)
