Talk:Basis (linear algebra)

message: Given that the article is entitled "Basis (linear algebra)", the first sentence should read "in linear algebra" rather than "in mathematics" to establish an appropriate context for the article. "in mathematics" seems unnecessarily vague and, lacking a clear scope, many articles seem to become very fragmented and disjointed. AP295 (talk) 16:33, 21 January 2021 (UTC)
replies: text: This has been discussed many times in Wikipedia; see MOS:MATH#Article introduction. This is aimed to help readers with little knowledge to decide whether this article may be useful for them. As "linear algebra" is in the article title, repeating it in the first sentence is totally useless. Moreover, readers who have encountered the topic in another area of mathematics or physics may think that the article is not for them if the first sentence is too restrictive. This is why it is standard in Wikipedia to put "in mathematics" even for very specialized subjects, as soon as it is used in many areas of mathematics. So your opinion goes against a long standing consensus. D.Lazard (talk) 16:52, 21 January 2021 (UTC)
replies: text:  From variance, In probability theory and statistics, variance is the expectation of the squared deviation of a random variable from its mean. The concept of "variance" is used in many many different fields. Sociology, biology, economics, etc. and in such instances it is commonly understood as an application of probability/statistics. Similarly, linear algebra can be applied in many areas. From the article on linear algebra, Vector spaces are the subject of linear algebra. Is the word "basis" used for anything other than the basis of a vector space? And if so, would such cases belong in this article? I don't think so. This change isn't that important so fine, we can keep it this way. I don't understand you though. There are only nine featured articles in mathematics. This is a low quality article and it needs to improve. AP295 (talk) 17:14, 21 January 2021 (UTC)

text:  And bizarrely, the page Linear algebra isn't even linked in this page until below "external links". AP295 (talk) 17:17, 21 January 2021 (UTC)

text:  Actually, I think my edit agrees with MOS:MATH#Article introduction. Any "basis" not pertaining to vector spaces (the subject of linear algebra) is probably best covered in a separate article.  AP295 (talk) 17:52, 21 January 2021 (UTC)
replies: text: The article title specifies the subfield, so repeating it does not help anyone, whereas if someone doesn't know what is linear algebra then it is more helpful to let them know it is part of mathematics. --JBL (talk) 18:10, 21 January 2021 (UTC)
replies: text:  Happens all the time. I thought the article was about baseball before I read that it was actually about math. Imagine my shock when I learned the cardinal numbers weren't a baseball team. AP295 (talk) 19:17, 21 January 2021 (UTC)

text: A high-schooler doesn't know what "linear algebra" is, but does know what mathematics is, and the lead should be accessible to them. Just knowing the two words "linear" or "algebra" could reasonably given a non-mathematician the thought that it might be a part of economics or statistics, or it might be a nonsense phrase they can't make sense of. "In mathematics" is better. — Bilorv (talk) 01:46, 3 February 2021 (UTC)

text: I think mathematics is the best choice here, as anyone working in mathematics who says "basis" is referring to this concept, regardless of whether they are working in linear algebra or not. Similarly, the article on square number does not say "in number theory". Awoma (talk) 17:44, 16 February 2021 (UTC)
thread_title:  "in mathematics" vs "in linear algebra" 

message: Hi, the object of the verb "called" need bold or italic font. But here as you say "target of a redirect" we should use italic instead of bold. Is that Ok? Hooman Mallahzadeh (talk) 13:44, 17 November 2021 (UTC)
replies: text: In this case, bold is forbidden per MOS:NOBOLD. If the definition would be here, emphasizing with italic would be recommended. Here, the definition is in the linked article, and a sufficient emphasis is provided by the blue of the link. D.Lazard (talk) 14:06, 17 November 2021 (UTC)
replies: text:  So, please review my last edit. Thanks. Hooman Mallahzadeh (talk) 14:13, 17 November 2021 (UTC)
