The site refused to let me read it all, but I can tell you it's horseshit. You can't "short-circuit" a chaotic dynamic. The two body problem is ordered and you can guess where the two bodies will be at some abitrary future, but a choatic dynamic (like the 3 or n-body problem) will not be analyzable--it's not regular. The *only* way to predict what will happen in a 3+-body problem is to actually simulate it. Done. Mark
