>What is wikipedia? Is is available on the internet?

The better question would be "is it available anywhere else"?
Try this: http://en.wikipedia.org/wiki/Divine_proportion

>I may have used it quite a lot if I came across information on the web by searching google. I do that a LOT (search google when I'm looking for quick references since all of my books are at home). I don't pay close attention to the website unless it is overseas, obviously slanted, or advertisements.

The name is self-explanatory in this case - it's a wiki, and it's an encyclopedia. I love the dry scientific and neutral style of the texts. Seems to be a lot of people have invested a lot of time to put the database together.
