@Forever_Free Are you saying that the information I provided is questionable at best (on topic), or that the information contained within Wikipedia is questionable at best (off topic)? If the former, everything I said is backed up by the links I provided. If the latter, then see this article and this letter for some interesting observations on the matter.
In any case, encyclopedias are by nature nothing more than starting points for knowledge. No single article, whether it be found on Wikipedia or in the Encyclopædia Britannica, can give you understanding of a topic. It can only start you down the path of understanding.
