Re: Re: [Fis] Re: What is the definition of information ?

Information is the pointing out of one alternative among many. Therefore, there must be several alternatives. The only way I can find something made up by man's phantasies in which something could be otherwise is the descision whether one regards a set of object as a collection of individual things (here, one recognises the DIFFERENCES) or one regards them as groups which share properties (here, one recognises the SIMILARITIES).
Our thought-up (mental, theoretical, abstract) constructs are considered well-made in that case if they do not allow for ambiguities. It is a tragedy of our biological heritage that we have the natural urge to think error-free, and that a deviation is causing a feeling of error, although in nature quite many things do have a slack and a deviation. We simply over-idealise into a stupid and useless formalism, which negates the natural imperfection in Nature.
This natural imprefection has the order of magnitude of 3.8 which is not much relative to the two extents which deviate relative to each other, namely some 10E160 and 3.8x10E160.
Sorry to bore you with actual, factual prosa while you are doubtlessly slaying dragons and hunt for mysteries.

Still: information is the pointing out of one alternative among several. (This implies that a) the more alternatives, the more information; b) information is, like as anything really rational, mappable into additions.) There is absolutely no need to romanticise about information. This makes a sham extasy like playing peek-aboo with a child. If I pretend that Information iss such a heavy and complicated matter, then I get very excited if I can hack it. If it is just the pointing out of a summand among many summands of an addition, then it sizzles and a feeling of "so what" comes along. Are we in science to have excited inner workings or are we there to work?

Hope you come down from romanticism. Dry and boring stuff does have some merits, too. (Mostly, the merits are technical and therefore economical. It may be that we lose in the FIS chatroom the excitement of discussing something mysterious but at the same time we may get along with the boring and less-than-peppy task of understanding how Nature packages info (be it in the memory or in genetics) and translates probablities into certainities (be it in physics or chemistry).
