Few corrections corresponding to my areas of expertise.
I'm no fan of something I read a while ago on another user page: only edit articles not being in ones own area of expertise, because this would contribute to neutrality; my opinion and my experience is that this contributes to wrong interpretations (e.g. wrong translations from other languages when citing) or even to citogenesis[1]... and it's difficult to find references to real self-evident basics of an area of expertise, and thus difficult to correct them on Wikipedia.
