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)

@Weaky3: As an encyplopedia, Wikipedia follows the literature, by design. And I'm not English: my primary language is Dutch. I'm also fluent in French, English and German, and, thanks to my classic education, I can fluently read Italian and modern Greek newspapers whithout a dictionary. By the way, always assume good faith from your fellow editors. Personal attacks are not tolerated here. Cheers. - DVdm (talk) 17:08, 11 March 2023 (UTC)

On the edit on Michelson Morley experiment

This is the source you asked: https://en.wikisource.org/wiki/The_Relative_Motion_of_the_Earth_and_the_Luminiferous_Ether

As you can see in the first line,Or even in the title, the experiment was on finding the velocity of earth. They assumed the existence of aether to be a fact.

While the experiment have disproved the existence of aether, it was not their intention. In fact Michelson Morley was a failed experiment. They didn't get what they were looking for.

Please sign all your talk page messages with just the four tildes (~~~~), without actually typing the <nowiki> tags. When you type the tildes, your signature will be substituted, unless you type the tags. — See Help:Using talk pages. Thanks.

@Sophile249: According to the literature, the primary aim was to prove the existence of the ether, by measuring the velocity of the earth through it. We must follow the literature.

Also, take a look at wp:BRD: when a Bold edit is Reverted, and you disagree, start a Discussion, preferably on the talk page of the page that your were editing. Reverting again as you did here is considered wp:edit warring and is not allowed. Cheers. - DVdm (talk) 09:57, 19 March 2023 (UTC)

Apologies. I thought that you may not see my comment, that is why I reverted again.

Gravity

there is an article on gravity in the antiquity section which describes In India, the mathematician-astronomer Aryabhata first identified gravity to explain why objects are not driven away from the Earth by the centrifugal force of the planet's rotation but i can't find any sources depicting about his claim please remove it Ppppphgtygd (talk) 05:46, 23 March 2023 (UTC)

@Ppppphgtygd: I have added a source, albeit a self-published one: [1]. - DVdm (talk) 12:02, 23 March 2023 (UTC)

Is that source reliable I mean it is given as self published and secondly we need to see whether aryabhatta talk about gravity in his book Aryabhatiya.I didn't find any source about him talking about gravity in Aryabhatiya. Ppppphgtygd (talk) 12:39, 23 March 2023 (UTC)

@Ppppphgtygd: I think the source looks reasonably reliable (—see [2]—), but, as you can see, I did tag the reference with a {{Self-published inline}} template anyway. This invites other contributors to find a better source. - DVdm (talk) 15:10, 23 March 2023 (UTC)

Ok Ppppphgtygd (talk) 15:44, 23 March 2023 (UTC)

I have rejected that content outright as disputed and not well supported, based on higher quality sources that contradict or cast doubt on it. Other strong claims of discovery/contribution in that section of the source are also easily rebutted (example: our Aryabhata article has multiple sources that heliocentrism is at best uncertain but more likely not true). For whatever reason, Indian educational materials tend to over-claim Indian contributions in history. DMacks (talk) 08:46, 24 March 2023 (UTC)

@DMacks and Ppppphgtygd: Yep, probably a good call, thanks. I had a closer look at the book. On page 6 it says: It will become immediately obvious that the genius of ancient Bharata indeed forms the basis of world civilization, in contrast to the idea that 'miracles' in Greece, Mesopotamia, Egypt etc. influenced India somehow and anyhow from somewhere and anywhere. No wonder I failed to find a proper secondary source in a non-self-published source. Cheers. - DVdm (talk) 10:10, 24 March 2023 (UTC)

good, nowadays a lot of articles are been vandalised by a lot of people in Wiki thanks for removing it Ppppphgtygd (talk) 10:14, 24 March 2023 (UTC)
