A lot of these stubs are pretty low quality, and could use going over by someone with some knowledge of the subject (or even just Wikipedia experience). I've cleared out a couple of stale merge proposals, and added a reference, but there is much more work to be done. Some of these stubs really could use expansion as well.

If members of this project could help writing those articles, that would be much appreciated. See our journal-writing guide at WP:JWG for help on writing these articles. Note that some of these might be better as sections of another article (usually publisher, or affiliated society), similar to Australia ICOMOS#Historic Environment.

Hello fellow Wikipedians. I am in the process of creating an article about the 4D shape, the “cubinder”. It was previously red linked on other articles, and I was surprised to see it was not already an item listed for creation by Wiki Projects Mathematics, as the duocylinder and spheriender are already articles. I require help to improve the draft, as I require more formulae, sources, and additional information to create this article. You can access this page at User:Darnburn98/Cubinder, please come on over and help improve this article to get into the main space!Darnburn98 (talk) 22:26, 20 January 2017 (UTC)[reply]__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"2017-01-20T22:26:00.000Z","author":"Darnburn98","type":"comment","level":1,"id":"c-Darnburn98-2017-01-20T22:26:00.000Z-Draft:Cubinder_,_Needs_improvement_with_formulae,_sources_and_additional_informa","replies":[]}}-->

The WikiJournal of Science is a start-up academic journal which aims to provide a new mechanism for ensuring the accuracy of Wikipedia's scientific content. It is part of a WikiJournal User Group that includes the flagship WikiJournal of Medicine.[1][2]. Like Wiki.J.Med, it intends to bridge the academia-Wikipedia gap by encouraging contributions by non-Wikipedians, and by putting content through peer review before integrating it into Wikipedia.
Since it is just starting out, it is looking for contributors in two main areas:
Editors
See submissions through external academic peer review
Format accepted articles
Promote the journal
Authors
Original articles on topics that don't yet have a Wikipedia page, or only a stub/start
Wikipedia articles that you are willing to see through external peer review (either solo or as in a group, process analagous to GA / FA review)
Image articles, based around an important medical image or summary diagram

In perspective projection section should be x' = x/w_c and y' = y/w_c instead of x' = x/z and y = y/z
That's meant to be a projection onto the plane . In homogeneous coordinates, this is the plane , so actually either form is correct, and the version with z in the denominator seems more natural to me.

Also, the affine coordinates of the image are and the homogeneous coordinates of the same point are denoted here (note the colons). As the homogeneous coordinates are defined up to the multiplication by a scalar, for defining affine coordinates, they can be used only in a homogeneous way (that is the numerator and the denominator must be both linear in homogeneous coordinates), which is not the case when you write D.Lazard (talk) 14:48, 28 January 2017 (UTC)[reply]__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"2017-01-28T14:48:00.000Z","author":"D.Lazard","type":"comment","level":3,"id":"c-D.Lazard-2017-01-28T14:48:00.000Z-S\u0142awomir_Bia\u0142y-2017-01-28T12:33:00.000Z","replies":[]}}-->
