The Math Behind PageRank 131
anaesthetica writes "The American Mathematical Society is featuring an article with an in-depth explanation of the type of mathematical operations that power PageRank. Because about 95% of the text on the 25 billion pages indexed by Google consist of the same 10,000 words, determining relevance requires an extremely sophisticated set of methods. And because the links constituting the web are constantly changing and updating, the relevance of pages needs to be recalculated on a continuous basis."

If google used a single computer to do all the work, and truly did 80*25B^2 operations, they'd be morons.

So it means the only way that Mr. A will come across Mr. B's website is if he kept on looking for 100s of result pages or if he just chanced upon it via something he read about earlier. Doesn't it defeat the purpose of making the searches more relevant, specially since lots of webmasters actively use PageRanking system to get better ranking on the search index. Where does that leave the people with worthwhile content but not much popular backing?
(I would like to clear that I am not trying to knock this system or anything, I am just curious about the implications for small-but-good-content website owners)
