If you have been voting for politicians who promise to give you goodies at someone else's expense, then you have no right to complain when they take your money and give it to someone else, including themselves.

Randomness?

A few years ago, I heard a story about a university experiment of pattern analysis on random numbers, which I remembered something like this:

Some university has two programs running simultaneously on a mainframe. One perpetually generates a stream of random numbers – mathematically random, not like a low-level RND pseudorandom function found in many programming languages. The other one perpetually analyzes the stream for repetitive patterns. Short repetitions are relatively common, but every so often, a repetition occurs that is statistically extremely improbable. Analysis shows that an even more improbable percentage of these occurences happened within an hour of some major world event – earthquake, war or terrorist attack, death of a world leader, etc.

The story has many of the hallmarks of an urban legend, especially the whole "powerful knowledge They don't want you to know" feel of it. I had thought about it a couple of times, but had mostly forgotten about it... until yesterday, when I read this post.

I commented on it, and didn't get any direct answers, but there were a couple of (confrontational sounding) comments from one reader trying to get me to defend the claims of the story. I explained that I was not defending it, I was just wondering if anyone had heard of it and whether or not it was a hoax.

As I was trying to properly word my response, I thought it would be a good idea to find a reference to explain the meaning of "mathematical randomness" as I understood it. When I googled some search terms, the FIRST link listed both explains the concept, and has a link to the EXACT EXPERIMENT I was asking about in the first place - noosphere.princeton.edu.

How random is that?!?

The experiment is not quite what I remember. The premise of the experimenters sounds like new-age-global-consciousness nonsense, but the experiment itself is interesting (just click on the data access link, and there are several options available for viewing the data itself).
