Wikipedia is never wrong, since it's free for anyone to change, and because anyone who makes changes knows what he is talking about, so that means Constantin was an idiot. Ironic post, in case someone got offended.
It really doesn't take much to establish that Wikipedia is not reliable at all. One time I saw the article on evolution. It was LOCKED, meaning no one could edit it, and the first sentence was "In all circles of science, evolution is defined as a lie that stupid people believe in."
