Factual accuracy of your recent edit to Tensor

Hi. I saw your recent edit to Tensor. I am not sure that the factual accuracy of your sentence is correct. 96.227.223.203 (talk) 12:37, 1 July 2023 (UTC)

That surprises me, because (A) it builds off your recent edit, and (B) it merely summarizes one of the treatments given in the Definition section. What is your objection? (And if you want to have a discussion about this specific article, then it would be better done at Talk:Tensor.) Mgnbar (talk) 12:46, 1 July 2023 (UTC)

I made a mistake in my original edit. I should have created a new paragraph, which I have now rectified. BTW the (1, 1) notation you added may very well be correct, but I have not reinstated it due to my shaky familiarity with the subject, and for that I do not want to be responsible for adding something of which I have not the knowledge. :) 96.227.223.203 (talk) 12:52, 1 July 2023 (UTC)

It's a tensor of type (p, q), where p = 1 and q = 1. This is all explained in the article.

Tensors are "generalized matrices" only insofar as their coordinates form arrays. This is the relationship between the sentence that you added and my revision of it. So I do not view the current version as a rectification.

In general, it's good to do Wikipedia:Be bold, but it's best to be bold after familiarizing oneself with the content already in the article. Regards, Mgnbar (talk) 21:43, 1 July 2023 (UTC)

By the way, it's possible that you are interested in Tensor (machine learning). You might also want to read the talk pages of these two articles, to see how much argumentation has gone into figuring out their relationship. Mgnbar (talk) 12:50, 1 July 2023 (UTC)

Edit revert

Hi, I noticed that you reverted my edit on Andaman Islands. While the change to the infobox name was accidental, was there any issue with the image being changed to my Commons upload? Given that I probably should have included an edit summary. ~ ՏԹՄՐ (✉ • ✎) 10:18, 11 September 2023 (UTC)

Yes, an edit summary would have helped me understand your motivation. And yes, we all make typing errors. :)

Regarding the figure: Partly I reverted because it seemed that similar articles, such as Nicobar Islands, had standardized on a map style. But now I see that there is no standardization. In my opinion, your new map is not better or worse than the current one. So I don't plan to revert you again. But you might consider engaging with Wikipedia:WikiProject Maps, where people discuss this sort of thing. Mgnbar (talk) 17:15, 11 September 2023 (UTC)

Colorblindness edit

I am new to editing on Wikipedia. Sorry if I am not doing something correctly. I have a rare genetic vision condition called BCM (1 in 100,000 people have it). It is so rare that I did not get a diagnosis until I was 57 years old. Very few eye doctors have any experience with it which means they misdiagnose it. My edit is trying to help other people that do not know what they have to find out. BCM was already discussed in the colorblind article but is hard to find and has some inaccuracies. I wanted to add a sentence to the beginning paragraph to help others like myself figure out what they have as easy as possible without having to wade through the rest of the article. For someone who knows they are colorblind and that there vision is generally bad but don't know what their conditions is, and neither does their eye doctor, one of the first things they would do is go to Wikipedia and look up colorblindness. However, the bulk of the article is talking about typical color blindness issues and is not easy to go through and figure out that they have BCM. The sentence I added is no different than the previous sentence which points out that Achromatopsia (another rare eye disease) is the complete absence of color vision and lists the added symptoms. I just tried to add the same kind of sentence for BCM to help people like me figure out what they have. Dean402 (talk) 01:45, 2 November 2023 (UTC)

Hi, Dean402. Because this conversation is specifically about the article Color blindness, we should hold this conversation at Talk:Color blindness, so that everyone interested can join in. In a few minutes, I will start a new section there. Mgnbar (talk) 01:55, 2 November 2023 (UTC)
