Some minor touches[edit source]

I sorted the Topics, removed "Topic:" from each of the subdivisions' names, created a new Elementary Mathematics division to help reduce clutter, and fixed a couple other minor details. MichaelShoemaker 01:12, 3 February 2009 (UTC)[reply]

most-perfect magic square from the Parshvanath Jain temple in Khajuraho
earlier contribution Only Three Squares,
Only One Pattern

Dear friends,

I was on a long wikibreak. I started to work again on most-perfect magic square, see sandbox/squares, sandbox/squares (details), Values of the Chautisa Yantra_magic square and commons:project:Featured_picture_candidates/File:Magic square at the Parshvanatha temple, Khajuraho.png.
The informations are to large for a Wikipedia article. Please ket me know at user talk:Gangleri if somebody can cooperate in writing, proofreading, advising about these topics.

links at The On-Line Encyclopedia of Integer Sequences!

I have some ideas about making a generalisation of the Frénicle standard form using Galois group (see Galois theory) and residuals (see Isomorphism, Automorphism) to show that there is only one "generalised esentialy different" most-perfect magic square
examples ilustrates some of the homeomorphisms

Best regards and greatings from Munich. Best regards

Speaking of that, where is a good place for collaborative research in mathematics in general? DariusGoad (discusscontribs) 20:56, 12 August 2013 (UTC)[reply]

PDF Files and Audio Books , The Wiki3[edit source]

I'm very much interested in Mathematics, maybe a bit more compared to other areas of Science.... Does anyone think it would be a bit more interesting if we could download or view online mainly pdf, or other file reading formats of the main subjects and.... if Wiki volunteers, would want creating general knowledge audio books of the main subject...

eg.... A Main book about science and another separate audio book of subjects included, and sub audio books on parts of the subject book and goes on....

and we can call it wiki3 or Media3 (MediaWiki+mp3)

Does anyone think that would work....

Disorganized topics list[edit source]

It seems like the topic list could be better organized. I'm new to editing so I don't want to do it myself, since I'd worry that I'd break a link to a page. But is "fundamental mathematics" different from "college mathematics" and "elementary mathematics" and "secondary mathematics"? And then there's another category of "general mathematics"? And "trigonometry" falls underneath several of these, so probably shouldn't be such a high-level topic. It would be good to collapse and clean these categories. And is "properties" really deserving of a whole topic? --Addemf (discusscontribs) 23:20, 4 July 2021 (UTC)[reply]

Categories list is difficult to read on mobile[edit source]

Someone with experience in Mathematics needs to adjust the categories into subcategories. See Wikiversity:Categories#Category Sources and Hierarchy for appropriate structure(s). -- Dave Braunschweig (discusscontribs) 03:09, 12 December 2022 (UTC)[reply]
I'd be happy to adjust the categories, I just can't figure out how it's all structured in Wikiversity. You try to edit the category page and it inherits from another page. You go chase that page and it says that it inherits from somewhere else. You go chase that page and can't see where the data is coming from.

Recommended sequence of courses[edit source]

I wonder if anyone would agree that it would be nice to have, as prominently displayed as possible, a recommended sequence of courses? The category listing seems like the first and main thing that a new viewer would look at to see what's available here, and it really leaves one with a sense of disorganization and not much of a sense of what is available.

I would place Arithmetic as a foundational course, after which we can list Algebra, then Geometry, Calculus, Discrete Math, Linear Algebra, and so on. I don't know exactly how we would display and maintain the recommended sequence. We might also want to display a "tree" structure rather than a straight-line. But something like this seems like it would be very helpful to a new visitor.

Unfortunately I'm not familiar enough with how to edit this sort of data to do it myself, but I'm happy to discuss ideas if anyone knows more than me about how to do it. Addemf (discusscontribs) 06:14, 13 March 2024 (UTC)[reply]

I have just added a section on the portal page. For now it is just a plain text list. I hope to eventually internally link some of these to courses that have already been partially or fully implemented.
I also welcome any corrections or additions to the list, this is only a first attempt at presenting some useful organization. Addemf (discusscontribs) 17:35, 13 March 2024 (UTC)[reply]
Also, it occurs to me that we may have several different people producing several different versions of the same course. For instance, I have been thinking about creating a course on "reasoning", but one aimed at philosophers, scientists, and mathematicians. It will overlap heavily with the existing course on discrete mathematics for computer scientists, and one could take either course in order to satisfy the "discrete mathematics" prerequisite listed in the "Suggested Courses" section. But how would people know that it exists?
Would we want to (a) make these links to a page of links to courses? Or (b) list the various course options directly in the recommendation section of the portal?
I think to keep the portal looking somewhat clean, I'd favor (a) but want to hear if anyone has other thoughts. Addemf (discusscontribs) 18:32, 13 March 2024 (UTC)[reply]
