Dear Bruno, I decided so many times not to reflect to the esoteric sci-fi assumptions (thought experiments?) on this list - about situations beyond common sense, their use as templates for consequences. Now, however, I can't control my 'mouse' - in random and probabilistics. * Bruno quotes in " -- " lines, like the starting proposition: "It is because an event can be random or probabilistic..." * "...the perfect throwing of the perfect coin gives an random experience with a probability "measure" HEAD = 1/2, TAIL = 1/2...."

Wrong. A "PERFECT coin PERFECTLY thrown gives ALWAYS either HEAD or TAIL. It is those imperfections unobserved(?) that makes the difference in the outcome to 50-50. The only difference that really counts is the starting condition - whether it is thrown head or tail UP. To your subsequent 3 questions the answer is YES - depending how you identify 'probability'. (I don't). To your evaluating paragraph "Fair Enough": fair enough. That makes my point. * The "experiments with sleeping in the room with whiskey" are above my head (=my common sense). The Einstein conclusions show that even a big genius like him cannot cope with epistemic enrichment coming AFTER his time. (Which extends into the contemporary novelties as well?!) "...Einstein missed comp by its "conventionalist math" blindness perhaps, togethet with the fact that he was not interested in computer science. ..." I admire Kim's scientific tenacity to absorb your 'explanations' to the level of asking resonable questions. I could not spend so much time to submerge myself - and - maybe I am further away from your domain to do so. Thanks for the (*) added post scriptum, I missed it so far. One word of how I feel about probability: In the conventional (scientific/math) view we consider model domains for our observation (interest). Within such domain we 'count' the item in question (that is statistical) irrespective of occurrences beyond the boundaries of that domain. The "next" occurrence in the future history is undecided from a knowledge of the domain's past history in our best effort: we can consider only the 'stuff' limited into our model, cannot include effects from 'the rest of the world', so we cannot tell a 'probability' of the 'next' occurrence at all. Ominscient is different. I am not. Thanks for an interesting reading.
