Please stop being a miserable delete artist   I note that almost all of your edits are to destroy somebody elses well meant contributions   Certainly we need to keep rubbish of the Wikipedia but we do not need self appointed self righteous policemen picking at details   That behaviour poisonous Wikipedia  It is hard to encourage new editors to contribute when you just beat them up over pedantic nonsense  In my case you attacked a noncontroversial contribution to an article because of references  Not because you disagreed with it or even understood it  Just because of the legalistic issue of references  And the article does actually read a bit like a company sales promotion but you would not have noticed that more serious issue  Well Ill tell you a dirty little secret about Wikipedia  Lots of good contributions do not have references  Particularly about maths science and technology  But just because some well meaning editor does not go to the extra effort cite does not make it original research  If there is controversy then certainly references are essential and need to be good ones  But most of the world is not controversial  Just look at your User Contribution history  What a miserable tale it tells  So if you must edit wikipedia please try to contribute positively rather than just focusing on picking on other peoples generous contributions
