i'm quite sceptical about the role of article-like lectures here on Wikiversity. When can an article-like page be more pedagogical and attract a sufficient number of editors that it becomes more useful to students than the corresponding Wikipedia (or Wikibook) pages? In SR and GR, we have these lectures:
i didn't want to compete with existing material, so it took me some time to realise how these should be classified and placed in the Topic:special relativity and Topic:general relativity, and in what way my own contributions (a course, which contains lectures in non-article format + exercises) would be complementary.
The reality on Wikipedia for physics/mathematics subjects is that even though in principle, Wikipedia is supposed to be "encyclopedic and not pedagogical", in practice the culture for physics/mathematics subjects is that the pedagogical quality is often quite high. My guess is that for a physics/maths course here on Wikiversity, the first question before contributing material should be: am i contributing something which is not already present or better done on the Wikipedia or on Wikibooks?
