This is beautiful. I've always thought sites like IMDB and Wikipedia are hypertext expressions of the purest form. As a nerdy kid, over a few years I read my way through a significant chunk of the early 1990's Groliers Encyclopedia set my Grandma bought me at Krogers. And it was never cover-to-cover reading, instead it was filled with hopping around, page-to-page, volume-to-volume. Start at oscilloscope, but what's a…

Ah yes. To me (to my productivity's detriment...) quite often when I visit Wikipedia it becomes a learning adventure. From one thing you can hop to the other, finding out all sorts of interesting and obscure things. To a curious mind like mine, Wikipedia is heaven!

From a mathematical perspective, this is actually not that surprising.

Think of the act of clicking the first link in the Wikipedia article as a function that takes in the page you're on and outputs another page.

If you call this function on itself over and over again (ie use the output of one step as in the input of the next step), you will eventually enter a loop. The proof of this is simple: there are only a finite number of Wikipedia articles, therefore you must eventually reach an article you've seen before. (This is the same reason systems with a finite number of states cannot be chaotic.)

Since it's necessarily true that all articles will eventually reach a loop when you iteratively click the first link, we have to ask: how unusual is it that they usually reach the SAME loop?

I can't replicate it, but I encountered a weird bug. I entered "Star Trek" and hit Enter. The suggested items list appeared and I clicked on "Star Trek". Page titles appeared as normal, but everything appeared twice, like so: Star Trek Star Trek Cinema of the United States Film Cinema of the United States Recording Data Level of measurement Film ...etc until the last page title, "Reality" Seems like two processes wer…

I also got a weird one: Anime Animation The page you specified doesn't exist

That's funny because the first link on the Animation page is

http://en.wikipedia.org/wiki/Illusion

Is that an Easter Egg (illusion == doesn't exist)?
