"Obsolete theories in physics" -- English words have meaning
A quick review of the items listed on the Wikipedia Category page of "Obsolete theories in physics," one finds more scientific models, concepts, and ideas than actual theories. These words have specific meaning. As scientific terms, those meanings are both unique and well-defined.
In this particular instance, a scientific model is not a theory, and the false categorization of this page under "obsolete theories in physics" is disingenuous, misleading and damaging to Wikipedia as an "encyclopedia" (i.e. a "reference work...providing summaries of knowledge".
1. The plum pudding model is not a theory.
2. The plum pudding model is not an obsolete model.
3. The plum pudding model is not exclusively used today in physics.
4. The plum pudding model (1904) is in fact used today in many forms, and its publication history has accelerated since at least the 1980s.
To keep this false categorization in place on a commonly used platform of scientific information by everyday people, is an example of intentional disinformation.
Looking through the edits history, the last two contributors to reinstate the false categorization of this page had these remarks to substantiate their edits:
"The defining term here is obsolete physical thing, whether a theory, model or law" -StarryGrandma
"it definitely is obsolete" - Headbomb
As I noted in my corrective edit, theories, models and scientific laws are not physical things. They are ideas, abstractions, math. The category label says nothing of obsolete physical things. And to merely state that something is obsolete as reason for an edit is disingenuous and intentionally misleading. A colleague had similarly removed this categorization some time ago.
As a source widely cited by everyday users, Wikipedia is not a place for false information.
Words have meaning. Incorrectly used and placed on a platform such as Wikipedia only contributes to a growing culture of disinformation that damages the integrity of the online community. Wikipedia is a platform for science communicators. if science communicators place false information here, it leads to confusion and damages the integrity of scientific knowledge. We have more than enough growing problems with conspiracy theories, and other pseudoscience gibberish in the real world to contend with that even "little" things like this can have significant consequences.
Let's look at some definitions relevant to this page and its incorrect categorization. (In fact, most items on the category page shouldn't be listed there)
Definition
''obsolete ''| no longer produced or used; out of date.
The plum pudding model is the direct orgin of the Thomson problem, which is a benchmark computational problem for every reputable electromagnetics simulation package/app today. It is certainly used today and not out of date. The plum pudding model is definitely not obsolete.
Definition:
''theory ''| a set of principles on which the practice of an activity is based.
The Thomson problem is premised on the set of principles of the plum pudidng model and is practiced today. In fact, most literature on the subject has been produced from the mid 1980s through today with applications including golf ball design, geodesic dome design, fullerenes modeling, spherical virus modeling, global weather modeling, and atomic phenomena. The plum pudding model doesn't fit the definition of a theory.
Definition
''Italic''model (science) | a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes
The plum pudding model was proposed as a conceptual representation of atomic structure and a framework in which the periodic table of elements could be better understood in the early 20th century. Thomson's own related later work in the 1920s, alongside the work of chemists Lewis and Langmuir for example, led to many foundational principles in chemistry including the octet rule and covalent bonding. These principles are used today. As a model, the plum pudding model is certainly not obsolete as it is the premise of numerous fundamental principles in physics, chemistry and biology -- not just physics.
This page should not be categorized in "obsolete theories in physics" ...and the list on the category page should be reviewed with an eye toward scientific and informational integrity.

:::It's as obsolete as a model of the atom can get. It has been outdated since the discovery of the nucleus. It has been further outdated since the discovery of quantum mechanics. The [[Thomson problem]] is a question that arose from it and has been studied for other reasons, but that doesn't make ''the plum pudding model'' anything other than an obsolete model of the atom.

:::For analogy: somebody figured out [https://www.youtube.com/watch?v=qS4H6PEcCCA how to draw Homer Simpson with epicycles], but epicycles are still an obsolete way of understanding the solar system. [[User:XOR'easter|XOR'easter]] ([[User talk:XOR'easter|talk]]) 14:20, 9 February 2023 (UTC)
::::The analogy to epicycles is without merit here even with an assumption that my intent is to use the Thomson problem as a stand-in for the plum pudding model.
::::Models ≠ theories. Scientific and grammatical fact. The category does not apply here. Categories about chickens do not apply to oranges. 2 + 2 ≠ 5. Certainly not if we're being serious, professional, or sane. [[User:Tjlafave|TJ LaFave]] ([[User talk:Tjlafave|talk]]) 21:09, 24 March 2023 (UTC)
::I'm a little bemused by the intensity of this challenge. Though the article may be a bit inaccurate in describing Thomson's corpuscular theory of matter, challenging the category makes no sense. —[[User_talk:Quondum|Quondum]] 23:09, 9 February 2023 (UTC)
:::@[[User:Tjlafave|Tjlafave]], you appear to be the author of the paper [https://www.sciencedirect.com/science/article/abs/pii/S0304388613001277?via%3Dihub "Correspondences between the classical electrostatic Thomson problem and atomic electronic structure"]. By categorizing this atomic model as obsolete we are not saying the [[Thomson problem]] is obsolete, or that papers on it are not valuable. [[User:StarryGrandma|StarryGrandma]] ([[User talk:StarryGrandma|talk]]) 19:20, 13 February 2023 (UTC)
::::This isn't about whether or not the Thomson problem is obsolete nor whether papers about it are of any value.
::::In as plain English as possible, the "plum pudding model" is not a "scientific theory." Categorizing the "plum pudding model" as a "theory" is scientifically and grammatically incorrect. Further categorizing the "plum pudding model" as "obsolete" is both disingenuous and scientifically incorrect for a variety of reasons I gave earlier and many more that have impacts in many branches of science.
::::''Ipso facto'', by multiple metrics, categorizing the Wikipedia page on the "plum pudding model" as an "obsolete theory(ies) in physics" is a error. Continuing to reinstate that error is intentional disinformation.
::::2+2 does not equal 5. Stating this on a mathematics page would be intentional disinformation.
::::At least half of the linked pages from the category page in question are errors. [[User:Tjlafave|TJ LaFave]] ([[User talk:Tjlafave|talk]]) 20:54, 24 March 2023 (UTC)
:::::{{u|Tjlafave}}, it seems that there is widespread disagreement over the precise criteria for inclusion in [[:Category:Obsolete scientific theories]]. This was also an issue at {{slink|Talk:Rayleigh–Jeans law|Not obsolete physics}}. I do not have strong opinions about what the inclusion criteria should be, but I think that [[:Category:Obsolete scientific theories]] should document them clearly and precisely. It would probably make sense for you to open an [[WP:RFC|RfC]] at [[Category talk:Obsolete scientific theories]], and I could help you with that process if you are interested.  — <span style="font-variant:small-caps">[[User talk:Freoh|Freoh]]</span> 02:01, 26 March 2023 (UTC)
:::::"the "plum pudding model" is not a "scientific theory."
:::::Not anymore no. At the time, however, it was so. Now it's obsolete, and no one uses it to describe the atom anymore.  <span style="font-variant:small-caps; whitespace:nowrap;">[[User:Headbomb|Headbomb]] {[[User talk:Headbomb|t]] · [[Special:Contributions/Headbomb|c]] · [[WP:PHYS|p]] · [[WP:WBOOKS|b]]}</span> 01:57, 6 April 2023 (UTC)
::I am also surprised at the heat of the initial query in this thread. I think it is misplaced. The plum pudding model is clearly a scientific theory, and it is clearly obsolete. I say these things with at least some authority, as I am a retired professor of history of science who specialized over my 40+ year career in the close study of theories in the physical sciences of the 19th and 20th centuries, particularly atomic theory. The definitions given at the top of the thread are deficient. Throughout the history of science, models can definitely fulfill the definition of theories. In fact, the definition given above of a model can also serve as an excellent definition of a theory: "a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes"; we speak (for instance) of the geocentric or heliocentric model of the solar system. The plum pudding model (his theory of the composition of the atom) died with advent the Rutherford-Bohr nuclear atom, as Thomson well recognized. "Damaging"? "False"? "Misleading"? No, none of these.[[User:Ajrocke|Ajrocke]] ([[User talk:Ajrocke|talk]]) 18:17, 30 April 2024 (UTC)
