My Pensieve

It is well known that PageRank is at the heart of Google's technologies (at least, when it was growing).
Ask someone, "why is PageRank called so?".... They will tell you, "They rank pages. Page... Rank... get it?... duh.".

But, Page stands for Larry Page's last name!

Also, the output of PageRank is an eigenvector. As simple as that.

So, someone called it the $ 25 billion eigenvector!

It pays to be good at maths.

To understand PageRank, I recommend that you read the following (in order):

Interesting Snippet: Larry Page's brother was a techie too. He sold his eGroups company to Yahoo! for
a cool half a billion dollars
