dp x dx > h / (2 x pi) = Planck’s constant / ( 2 x pi )

Zawodny claims that Pagerank is dead. He says that the act of Google trying to “understand” the web caused the web itself to change. All this because his website has a higher pagerank (on his first name) than his blog. So blogs kill Pagerank. It could be very reasonable to think that the Google people adjusts the importance of blogs, and it could be very reasonable to think that it’s okay. But I’m quite sure that it’s not very reasonable to announce a technology’s death just because of this.

I don’t se the Heisenberg Uncertainty Principle relation either. Well, it would be there – if Google decided to crawl itself.

Let me state this notion more precisely. Suppose a particle has momemtum p and a position x. In a Quantum Mechanical world, I would not be able to measure p and x precisely. There is an uncertainty associated with each measurement, e.g., there is some dp and dx, which I can never get rid of even in a perfect experiment!!!. This is due to the fact that whenever I make a measurement, I must disturb the system. (In order for me to know something is there, I must bump into it.)
