Adrie, Glad you liked the examples. I don't do math so I never expected my explanation of the problem to do it justice. But do you think my interpretation of it is an example of chaos arising from a relatively simple deterministic system is incorrect?
Here is another simple example you might like. If you have a language with as few as two words in it; you can use it to generate an infinite number of sentences.

Krimel , the three body problem was solved long ago by Karl Sundman, the n-body problem is the same as the three body problem but then n(number) represents any other than 3body, so multiple body's. This proves that poincare's approach (chaos) was wrong, he failed. i'm impressed with your impression on the subject, but,.....your explanation/interpretation of the 3 body-problem is not wat the three body problem is about. The problem does not stand for the relative impossibility to predict the relative positions at "a " moment in time, but for this . It seemed to be an impossibility to ,given the positions at a moment in time , backwards predict all previous occupied positions, and furthermore predict all future positions derived from this moment and positions. this is not about relativity,but about the gravitational interaction on the body's and it only appeared in the past to be a chaotic model, as poincare was thinking. it was not. Karl Sundman solved the problem with pure mathematikal force In the provided link you can read how Sundman solved the case,pay special attention to the endsentence proving the perfect concentric trajectory's of the body's/particles (same) http://mcs.cankaya.edu.tr/ogrenciler/proje2009Guz/200322031CemMOGULTAY/rapor .pdf Another example I like is pool. Billiard became something like the standard metaphor of Newtonian mechanics; a game whose outcomes and relations were perfectly describable in mathematical terms. Except it isn't. Mathematics can be used to describe and predict the outcomes of certain aspects of the game of pool but it cannot be all that helpful in predicting who will win a game of pool. It does what math does. It describes outcomes in a perfect world of Platonic ideals which no rough edges. ---Predicting the winner, this is the variable ,the human player, you cannot predict his behaviour, the outcome of the game is derived from this entity Pool is predictable if played by robots, the mathematikal model is descibable. greetzz, Adrie 2010/8/22 Krimel <[email protected]> > > [Krimel] > > Poincare's three body problem is another example.
