How does *the arrow shot at a target *(in Zeno's Paradox) *compute* the truth of the forall-exists quantifier construct in the Caucy definition? Or what is computing the truth of that for the arrow? When one simulates the arrow shot at a target on a computer using a numerical calculus software package, there are only floating-point numbers, and the arrow "gets to the target" because the finite floating-point number resolution makes it so. - pt -- You received this message because you are subscribed to the Google Groups "Everything List" group.
