This is a neat trick someone taught me.
Look up any word with a definition in Wikipedia and bring up the page. Then, click on the first available link within the article that is NOT in parentheses and NOT written in italics. Then keep on repeating this process for every resulting linked page.
Eventually you end up at "Philosophy".
It works so well that it blew my mind. A group of people in an online forum tried to break it and could only find TWO exceptions that loop back to themselves.
Worked starting with "analog".
Formula One took 22 clicks. It not really a phenomenon if you ask me. Everything is based on philosophy when you consider the definition. Philosophy is the study of general and fundamental problems, such as those connected with existence, knowledge, values, reason, mind, and language. That pretty much covers everything in existence. Not something that blows my mind, wikipedia is well connected throughout its articles.
