Random Precision

Yesterday my rando play played three consecutive tracks from the Van Der Graaf album "Present" starting with the opener "Every Bloody Emperor" and finishing with "Nutter Alert", this was followed by a couple of Spirit songs thwn that awful Cream song then two Stone Roses songs. At first I thought it had slipped off random play but as I was walking and I like the album I was OK with it.

A couple of months ago I was talking with Juliet and Kirsty and about how people don't really understand the concept of "random". She had provided a "random" data sample, then the requester came back and said they wanted data from Area "A" , Area "B" , well each area they covered. Kirsty pointed out that that this wouldn't be a random sample if you started applying criteria.

Jordan Ellenberg point to an American Lottery result where the same numbers were selected two draws in a row. In a true random selection 1,2,3,4,5,6 is just as random and likely as any other. Ellenberg points out that the improbable is highly probable. The nature of random is that it may appear ordered, it's not, but our minds always try to order things, and see logical patterns, and we can see logical patterns where the probability is just complete randomness and even chaos (think reading tea leaves and the I-Ching which is basically throwing sticks. You can add divination by cards like Tarot (I do have two Tarot decks but they are just works of art), which again uses randomness to determine fact, which really is not a practical or logical path to go down.

Well we are at Friday , and the real Football season starts today whith Sunderland playing Derby and Nottingham Forest take on Millwall. It looks sunny, but it looked sunny yesterday. I will walk into work today and listen to more random music
